2 SAFETY INSTRUCTIONS

2.1 The BRUKS-KLÖCKNER-Drum chipper is technically sound and safe to operate.

However, any machine can cause dangers if operated in an unsafe manner or by

personnel unfamiliar with the machine.

2.2 Every person concerned with installation, start-up, operation and maintenance of the chipper must have read and understood the complete manual, in particu-lar the section "safety instructions". The user is advised to have this confirmed by signature of the appropriate personnel.

2.3 The drum chipper is designed exclusively for the production of chips from wood. Any

other use is improper and no responsibility can be accepted by the manufacturer.

2.4 The user is responsible to protect the machine from foreign metal or rocks etc. with

appropriate devices, such as metal detectors, magnets, cleaning rolls etc.

2.5 The user must also ensure that the area surrounding the chipper is within the allow-

able limits for dust concentrations.

2.6 The inferred area and the movable fedoras must be guarded by fencing or barriers.

2.7 Noise control is to be provided as per local regulations.

2.8 Emergency stop buttons must be located in the immediate vicinity of the machine.

2.9 Near the chipper earplugs must be worn.

2.10 Unauthorised changes and modifications to the machine must not be done for rea-

sons of safety.

2.11 The user is responsible that the machine is only operated in good condition.



2.12 The operating personnel is required to inspect the chipper at least once daily and

report any defects or changes in operation immediately.

2.13 Regular inspection, maintenance and repair checks must only be performed with ma-chine at a standstill.

If for this purpose protecting devices, coverings or similar have to be opened or re-moved, the drum chipper must be prevented from accidental starting. This is normally done by locking out the main switch.

2.14 Any work must only be performed with machine at a standstill.

2.15 No protective or safety devices may be removed.

If it is necessary to remove guards for maintenance, they must be re-installed imme-

diately upon completion of the work.

2.16 The hydraulic unit is equipped with an accumulator. This may have to be inspected

and approved by the local authorities. The user is responsible to observe the local

regulations in full and obtain such approval if necessary as well as later re-

inspections.

2.17 The accumulator was sealed through TÜV, the appropriate authority in Germany and

the seal may not be removed.

2.18 All work on the hydraulic unit, except as listed here-in, must only be performed by

qualified tradesmen.

2.19 Prior to any work on any part of the hydraulics, all machine parts must be lowered.

2.20 Those units in connection with the accumulator will remain pressurised after lowering

of machine parts and motors are stopped. For this reason, the oilside of the accumu-

lator must be drained prior to commencing work on the hydraulics. (see chapter „in-

spection and maintenance“).



2.21 When working underneath the hood, it must be secured with the holding pin.

2.22 When working underneath the cradle, it must be secured with the cradle support

.

2.23 When working on the rotor it must be secured with the holding pin.

2.24 When working with the knives, cut resistant safety gloves must be worn.

2.25 Besides these safety instructions, all appropriate local rules and regulations must be

observed.



3 MACHINE DESCRIPTION 3.1 Constructional design

3.1.1 Rotor bearings

The rotor is running on oversized spherical roller bearings. The steel housings are

flanged and spigotted into the chipper housing side plates. Seals are lip type.

3.1.2 Feedroll carrier pivot

The feedroll carrier pivot connects the pivot/cradle with the machine housing and it is

formed by heavy spherical roller bearings in flanged steel housings.

3.1.3 Lower feedrolls and bearings

The feedrolls with special tooth profile are running in heavy spherical roller bearings

in flanged steel housings, spigotted in the housing sidewalls. Seals are lip type.

The teeth of the feedrolls are hard tipped to prevent wear.

The feedrolls are driven by a gear motor driving the first feedroll behind the rotor with

roller chain drives from roll to roll. These chain drives are protected by an oilbath type

chain case, completely enclosed, ensuring proper lubrication while keeping out dust

and dirt.

3.1.4 Upper feedrolls and bearings

These feedrolls are similar to the lower feedrolls with the exception that they are

mounted in a carrier, which pivots up and down to adjust for different sizes of pieces

to be chipped.

Drive is by gear motor to the first feedroll at the inlet.



3.1.5 Counter knife carrier

The anvil carrier is positioned on top of the anvil carrier support, welded into the ma-

chine. The anvil carrier is held by plates and pressure bolts on each side of the hous-

ing. To change anvils, the carrier can be moved laterally by hydraulics. Anvil carrier

and support are provided with replaceable wear plates.

3.1.6 Rotor

Description of bearings see 3.1.1.

The rotor consists of the welded steel rotor, the knives and knife mounting device.

The standard knife mounting is by clamping plates with bolts, tapered wedge type

knife clamping is also available. The rotor is provided with replaceable wearplates

underneath the knives.

The rotor is mounted onto the shaft utilising tapered ring locking elements.

3.1.7 Hood

The hood covers the housing over the rotor and provides access for knife changes.

The hood pivot is a bushing type.

3.1.8 Screen

The screen is of welded steel construction, heavily re-inforced and mounted in guides

in the housing sideplates.

3.1.9 Feedroll carrier

The feedroll carrier is a solid welded steel fabrication, and carries the upper feedrolls.

The carrier is pivoting from the inlet of the machine, see 3.1.2.

3.1.10 Machine housing

The machine housing is a heavy welded steel construction and carries all

aforementioned components.



3.1.11 Hydraulic plant

The hydraulic plant includes the hydraulic power pack, the cylinders and piping on

the machine.

The power pack consists of motor, pump, accumulator, tank and all control valves.

The connection from the ping to the power pack and to the cylinders is by high pres-

sure hoses.

3.1.12 Motor plant

On smaller machines with lower drive power the pulley will be normally mounted di-

rectly onto the motor shaft. The motor itself will be placed on slide rails and the whole

belt drive is secured by a protection cap.

High drive power and great belt tension powers (particularly when using flat belts)

require a separate bearing of the motor pulley. In those cases the motor and the pul-

ley are to be mounted separately on a console. Depending on the power transmis-

sion, connection is to be effected by means of a jaw clutch or bolt coupling. The pul-

ley is fastened by means of cone clamping devices on the shaft. The bearing is per-

formed by heavy roller bearings in plummer blocks. The whole console is born on

slide rails and can be moved on same by adjusting spindles for tensioning, respec-

tively loosening of the belt.

Also refer to the spare part drawings, chapter "Spare part drawings and piece lists"

mentioned in above groups.

3.1.13 Cradle support

BRUKS-KLÖCKNER Drum Chippers are fitted by standard with hydraulically driven

support rods used for supporting the swing when open for cleaning and repair works.

Support rods fastened on left and right side on extended cylinder supports with

knuckle eyes. Provide upper end with ball head. During machine operation placed

slanting to rear. With the swing completely open the rods are hydraulically moved

forward until reaching position under the ball socket in the swing-cylinder support,

then the swing is lowered by some centimetres until the swing is resting on the rods.



3.1.14 Run-up device (if requested)

The run-up device is a hydraulic donkey drive that with reduced electrical power in

combination with hydraulic power transmission shall overcome the existing inertia of

masses of the system of chipping rotor ? pulley ? electric driving motor.

The reason is to reduce or prevent the starting currents that would generate with di-

rect start by the main motors.

For this purpose, the system chipping rotor ? pulley ? electric driving motor is

dragged up to the rated speed of the main motors by an installed hydraulic motor.

When reaching the rated speed the main motors are hooked up into the electric net-

work with the result that high power withdrawal of the electric network is prevented.

Subsequent to reaching the rated speed and join-up of the main motors into the elec-

tric network, the hydraulic motor respectively the hydraulic power transmission is un-

coupled via a specifically previewed coupling.

3.1.15 Rotor hood locking device (if requested)

The hood locking is a hydraulically operated safety device ensuring the automated

operation of the drum chipper. The hood can only be opened e.g. for replacing the

blades at the chipping rotor, with the chipping unit stopped or out of operation. For

this there is an electric link to the hood locking allowing opening of the hood only if

the a.m. conditions are met.



3.1.16 Rotor turning device (if requested)

For positioning the blades in blade replacement position

With a hydraulically operated unit the chipping rotor of the drum chipper can be

automatically turned into the maintenance position (blade replacement position). This

is carried out with a specific ratchet construction driven by a hydraulic cylinder. Dur-

ing the work clearance stroke this ratchet engages into a toothed disc mounted onto

the rotor shaft, and turns it. By repeating this process the rotor is turned until the re-

spective position is reached.

Inductive proximity switches control the limits of travel of the hydraulic cylinder. With

standstill of the cylinder, a hydraulic shut-off valve blocks the cylinder is in the

reached position.

Because of the special shape of the ratchet and the blocking of the cylinder in main-

tenance position there is no need for a locking pin for blocking the rotor.

This also prevents overtravelling the maintenance position because of the rotor iner-

tia.



3.1.17 Screen basket

The chipper is provided with a screen changing device. The rear side of the chipper

and the screen changing device are forming a unit.

To unlock the rear side of the chipper release the swivelling screw fittings. Through

the hydraulic the screen changing device can be driven out. Before changing the

screen, the fastening screws have to be released.

3.2 Functional description

3.2.1 Stock feed The material to be chipped is fed to the chipper by a belt or vibratory feeder. The up-

per and lower feedrolls positively grab the material and push it to the rotor at a con-

trolled rate. The upper feedrolls adjust for height of the material to be chipped.

The pressure of the upper feedrolls on the material is generated by the weight of the

feedroll carrier and the hydraulic cylinders are used to reduce this pressure to the

minimum required for proper feeding. This will extend life of the feedroll teeth and re-

duce damage to the wood.

3.2.2 Chipping operation

The knives chip the material by cutting the length of the chip with the thickness re-

sulting from the knife angle and specific characteristics of the wood being chipped.

The chips are collected in the pocket below the knife and carried past the anvil. The

chips are now thrown out by centrifugal force, with the oversize pieces held back by

the screen and chipped again.

3.2.3 Material distribution

The funnel under the chipper embraces the whole scuttle of the machine. Also fine

material under the feedrolls would be taken and lead in the following conveyor.

3.2.4 Overload protection

For preventing overload of the main motor, the drum chipper is fitted with a load-

depending feed control. With the power consumption of the main motor reaching

rated current, the feed motors are disconnected (time-delayed). They are automati-

cally reconnected if the power consumption of the main motor drops to 70% of the

rated value



3.2.5 Start and run up

The machine is started with a hydraulic system up to rated speed to avoid high start-

ing currents. During run-up, the rotor speed is continuously monitored and adjusted

to rated speed. Only after remaining steady at rated speed, the hydraulic system is

switched off, and the main motors are switched on. The overriding clutch, which con-

nects hydraulic motor and electric motor, during run-up works in lock-in operation and

with switch-off of the hydraulic system in free-wheeling operation. This clutch works

wear resisting because of the hydro-dynamic clamping piece lift-off.

3.2.6 Hydraulic functions

• Reducing the swing contact pressure

The cylinders with the knuckle eyes on the swing are connected with the ac

cumulator on the hydraulic unit and are continuously pressurized. The function

is continuously active. The initial pressure is set with a manually operated

three-way cock.

4 TRANSPORTATION AND STORAGE 4.1 Transport rules and regulations

4.1.1 The drum chipper must be lifted with the lifting lugs as shown (see drawing below).

4.1.2 The drum chipper must be carefully handled, to prevent damage caused by force or

careless loading and unloading.

4.1.3 During transportation, the machine must not be exposed to large variations in tem-

perature (condensation) and shocks.

4.1.4 When using wire rope or chains, wooden blocks are to be used to prevent damage to

the paint.

4.1.5 The drum chipper itself is to be handled with utmost care.



4.2 Transportation fixtures Depending on method of shipping, various fixtures and protective devices may be

attached to the chipper. These must only be removed at installation or start up.

4.3 Storage at site If the chipper is to be stored at site, a protected storage area, free of vibrations, must

be provided. The chipper is to be covered to prevent dust and moisture from enter-

ing. If stored outside the chipper must sit on supports and not directly on the ground.

Machines and parts that are completely packed (in boxes, foil etc.) the packing must

not be removed until installation.

Bare metal surfaces are protected with a protective coating for about a year. Should

the machine be stored for longer periods, it is necessary to recoat these areas (for

instance with Valvoline Tectyl 506).

4.4 Break down for chipment The chipper is shipped broken down for shipment.

The following parts are shipped separately: - Gear motor with base

- Outboard bearing with support (if required)

- Guide rail for anvil carrier

- Hydraulic cylinder for anvil

- Hydraulic powerpack with hoses

- Knife adjusting jig

- Tools



4.5 Scope of supply The contents of the shipment must be checked on arrival against the packing list.

Any discrepancies, shortages or damages must be immediately reported to the

transportation company.



5 INSTALLATION

5.1 General comments

We recommend that the installation be performed or supervised by personnel of BRUKS-KLÖCKNER.

We cannot be responsible for damages caused through improper installation. Every person concerned with installation, start-up, operation and maintenance

of the chipper must have read and understood the complete manual, in particu-lar the section "safety instructions". The user is advised to have this confirmed by signature of the appropriate personnel.

The drum chipper can be mounted on a concrete foundation or a solid steel structure.

The design of the supporting structure is to be done by qualified persons according to

the loads in the enclosed general arrangement drawings.

In the vicinity of the machine sufficient space is to be provided for the operation,

maintenance and repair works.

If the chipper is installed at other than ground level, it may be desirable to install ac-

cess platforms.

A general arrangement drawing containing all necessary information concerning di-

mensions, loads and weights is enclosed. Installation is to be performed according to

this drawing.



Installation procedure: 5.2 Set-up and preliminary alignment Drum chipper is placed on foundation or support and aligned with the anchor or hold

down bolts.

Level drum chipper. To level drum chipper longitudinally place machinist’s level on

foot of chipper. To level drum chipper laterally use machinist’s level across belt

sheave or on side of crowned flat belt sheaves.

Levelling is done by means of the levelling screws in the base of the machine. If re-

quired the base is to be shimmed with large shims

Do not tighten down the machine after this preliminary alignment.

5.3 Installation of hydraulic plant The hydraulic unit is connected to the piping on the machine by means of the sup-

plied hoses. (See enclosed hydraulic diagram). The plugs in the fittings of the ma-

chine and power pack must be removed.

The hoses are ready for installation, the union must be tightened by turning the nut

one half turn after the point of noticeable turning force increase is reached, while

holding the fitting with a wrench.

This work is to be performed cleanly, so that absolutely no dirt or other foreign parti-

cle enters the hydraulic circuit.

The hydraulic tank is filled at the factory. The oil level must be checked by means of

the sight glass and to the upper marker if oil level is too low.

Oil used at the factory: SHELL Tellus 46.

For topping up only this type of oil is to be used. When changing oil, any other oil

with similar properties can be used. (see maintenance - lubrication schedule).

The hydraulic powerpack can be fixed to the concrete cinch anchors, sized according

to the size of the mounting holes on the unit. If the machine is installed on a steel



structure, it is recommended that the power pack be installed on vibration dampening

supports.

5.4 Installation of lower feedroll drive Install gear motor and base according to the general arrangement drawing.

The coupling halves on the shafts are pushed together after inserting the flexible

element by moving the whole gear motor. The gear motor is aligned as accurately as

possible with the levelling screws. If necessary, shims are to be used here, too. This

line-up is to be done carefully and accurately; dimensions and allowable tolerances

can be found in the attached installation instructions for flexible couplings (see ap-

pendix).

5.5 Final alignment The feedroll motors and hydraulic pump motor are connected electrically and run for

a short time. Check for rotation.

The top feedroll carrier is raised with feedroll motors running. The appropriate valve

can be activated manually (see chapter „Spare parts drawings and piece lists / as-

sembly hydraulic plant“).

Uneven, jerky movement of the cylinders indicates air in the hydraulic fluid. To bleed

the system, the highest fitting on each cylinder is carefully loosened until oil appears.

Unusual noises caused by metallic contact "pinging" or contact between feedroll car-

rier and housing indicates that the machine is twisted; the machine must be level

over the whole length. The machine must be re-aligned and re-checked until the

movements are satisfactory and quiet. The gear motor can now be re-aligned and the

whole machine and gear motor tied down.

The coupling guard is to be mounted over the gear motor coupling and fastened to

the foundation. The perforated plates are to be screwed down on both sides above

the slot.



5.6 Counterknife carrier guide rail installation When pulling out the counterknife carrier the guide rail has to be fasten with screws

on the anvil

5.7 Installation of hydraulic cylinder for anvil The cylinder is supplied complete with support and high pressure hoses and is

mounted as follows:

5.8.1 Dismount stop block from the pivot

5.8.2 Insert cylinder trunnion in pivot

5.8.3 Mount stop block

5.8.4 Connect cylinder rod clevis to anvil carrier with pin and secure it.

5.8.5 Pull out anvil carrier 3/4 of its length. This will line up the cylinder exactly.

5.8.6 If necessary, shim foot of cylinder support and fasten to foundation.

5.8.7 Connect hoses with piping on machine according to hydraulic diagram. Hoses are

provided with quick couplers; remove plugs in openings.

After this initial installation, it is a simple matter to install and remove cylinder. In or-

der to save space beside the machine, the cylinder may be kept separately and in-

stalled only when required.



5.8 Installation of motor and base Bolt slide rails to base and install motor. Place assembly on foundation and line up so

that both sheaves are in line. This can be checked with a straight edge or string

which must touch each sheave in two points without being bent.

Fig.: line up of sheaves Riem2.cdr

Before final tightening of anchor bolts the motor (or motor base) is to be moved over

the whole length of rails, while checking the alignment of sheaves in different posi-

tions.

It is very important that this line up is accurate and without twist; the motor (or motor

base) must rest equally on all rails.

5.9 Installation of drive belt(s) and guard Prior to installation, the grooves of V-belt sheaves or surface of flat belts pulleys must

be cleaned carefully and any oil, grease or corrosion protection must be removed.



5.9.1 Applying and tensioning of V-belts

For flat belts the proper tension is expressed in %. (The proper tension for this belt

see chapter „Technical Data“).

Fig.: Example of tensioning belt to 2%. Riem3.cdr

- Lay belt on flat surface and mark outside with two marks in a distance of 1000 mm

(short belts 500 mm).

- Carefully place belt on sheaves and tighten belt with adjusting screws until dis-

tance between marks has grown to indicate proper tension.

For example: For 2% tension the distance between the marks must be 1020 mm (510 mm) (see

Fig.).

- Distance of marks to be checked again after rotation drive several times by hand

to distribute belt tension equally.

- Flat belt drives do not have to be re-tensioned; therefore it will be useful to mark

the final position of the motor on the slide rails allowing the belt to be tensioned

very simply after removal for repairs.

The foregoing is only valid for flat belts made by SIEGLING under the name Ex-tremultus 85.



After installation of the belt is complete, the belt guard must be mounted as shown on

the general arrangement drawing.

5.10 Electrical installation Electrical installation must be performed by qualified personnel observing all local

rules and regulations

After completing the installation and all electrical work, start up procedure is to

be executed as follows:

6.1 Preliminary checks

• During shipment the rotor was secured against rotation by means of the

holding pin. This pin can now be removed.

• Check all bolts for proper tightness. The knife clamping bolts (or spindle

for wedge type clamping) must be checked with torque wrench supplied

with the chipper (see „operating instructions“).

• Check rotor space, chipper inlet and feedroll area for foreign objects

such as tools, hard hats, welding rods etc.

• Check electrical installation in accordance with all local rules and regula-

tions.

• Check rotation of all E-motors.

• Check oil and gas pressure in accumulator (see chapter „Inspection and

Maintenance“).

• Bleed hydraulic system by carefully loosening the topmost fitting on the

cylinders until oil appears.

• Check lowering speed of top feedroll carrier. This can be adjusted with

the flow control in the cylinder connection or throttle valve (see „Spare

part drawings and piece lists / assembly hydraulic plant“).



• Check lowering speed of hood. This can be adjusted with the flow control

in the cylinder connection (see „Spare part drawings and piece lists / assembly of hydraulic plant“).

6.2 Starting

• Start up chipper and check electrical interlocks and controls for proper

start up sequence and shut down sequence.

• Check all drives for correct locking and connection and if control works

correctly. Furthermore all electrically controlled functions are to be per-

formed several times.

• The proper function of all safety devices such as emergency stop, limit

switch for hood, safety switch at chipper inlet, metal detector, pull cord

switch, motion switch and starter is to be checked very carefully.

• If everything is satisfactory run chipper without load for about an hour.

Check for abnormal noises and watch bearing temperature (max. 70

deg. C on outside of bearing housing).

• Now the chipper can be run under load; it is recommended to start with

small amounts of wood and slowly increase to the full load capacity.

6.3 Subsequent checks

• After 4 - 5 hrs. check V-belts for proper tension and adjust if necessary.

• After 8 - 10 hrs. check all bolts for proper tightness.

• After one week check return filter in hydraulic power pack and change if

necessary (see „Inspection and Maintenance“).



7 OPERATING INSTRUCTIONS

7.1 General comments Every person concerned with installation, start-up, operation and maintenance

of the chipper must have read and understood the complete manual, in particu-lar the section "safety instructions". The user is advised to have this confirmed by signature of the appropriate personnel.

For the following description it is assumed that the controls have been supplied by

BRUKS-KLÖCKNER GmbH. If controls have been supplied by the user, they must

be executed in such a way that the functions correspond completely with the func-

tions described in this manual.

7.2 Operation of the machine When operating with normal loads on an even continuous basis, the chipper will op-

erate automatically without attendant.

When operating at maximum capacity with varying infeed material of large dimen-

sions, the infeed should be controlled by an operator. The upper feedrolls will be lifted up as long as the button "feedrolls up" is depressed. This enables the operator to make the indeed opening suitable for the required height. When re-leasing the button the feedrolls will lower again.

Feedrolls can be stopped and reversed to clear any jams or wedged in pieces.

The automatic load control stops the feedrolls upon reaching full load main motor

current. They will start automatically again when the current drops 30% below full

load. (This is adjustable). If the chipper is equipped with a brake (optional), the rotor

run out time is shortened considerably. The rotor brake is activated while depressing

the button rotor brake". The brake applies in intervals to prevent excessive heat build

up in the brake disc. Interlocks must ensure that the brake can only be activated

when the main motor has been switched off.



7.3 Knife change (general)

Knives and anvil must only be changed with switched-off (locked-out) machine. The

opening of the hood and movement of the anvil is interlocked and will only be possi-

ble after the timer has run out after switching off the main motor.

Before the timer is running out neither the rotor hood nor the anvil carrier can be extended out of the machine.

The release can be done only after switching off the main motor over press buttons.

If the machine is equipped with a motion switch (optional) it will replace the timer.

The release of these functions is signalised by control lamps.

For knife changes, it is imperative to wear cut resistant gloves to prevent accidental

cuts. This work must be performed in a steady well thought out way to prevent injury;

the knives are sharp.

7.3.1 Knife change

- unlock the rotor hood locking device

- Open hood by depressing button „hood up“. The hood can only be opened during

standstill of the rotor. When the hood is completely open the press button may be

released. If the press button is released before, the hood will remain in its posi-

tion. Upon reaching of the fully open position the safety pin must be inserted im-

mediately.

- Secure rotor against rotation with the holding pin.

This pin is inserted through the side plate into a hole in the rotor. This will also en-

sure that the rotor is in an ideal position to change a knife.

- Pull out knife toward the front.



- Clean out knife pocket, particularly the clamping surfaces and insert a new re-

ground knife. (For grinding and adjustment see „Inspection and Maintenance“).

- Tighten knife clamping bolts.

Start with a bolt in the center and then alternatively left and right. It is imperative

that the supplied torque wrench be used for this purpose (for required torque see

„Technical data“). Electrical or pneumatic wrenches must not be used. If the bolts

need to be replaced, a lubricant containing MoS2 must be used.

- Pull out rotor holding pin and rotate rotor to the next position by hand.

- After changing all knives the rotor holding pin is to be placed back into its holder

and the rotor to be rotated manually for control.

- After pulling out the safety bolt (if bolt skews, just gently tap the press button „hood

up“) the rotor hood is to be lowered by pressing the button „hood down“. When re-

leasing the press button while lowering the hood will remain in its respective posi-

tion.

- If the hood is completely closed it is to be locked with the rotor hood locking de-

vice.



7.3.1.1 Knife change



7.3.1.2 Counter knife change with clamped anvils

- Remove anvil hold down plates and the bolts on both sides of the machine. For

this purpose the counter nuts of the setscrews are to be released and the set-

screws to be screwed back. The fastening screws of the safety plates are to be

completely unscrewed and the safety plates to be removed.

- Extend anvil carrier and anvil by pressing button „extend anvil“ onto the rail placed

laterally at the machine. Please note that the anvil carrier can only be extended

when the rotor is fully stopped. If the hydraulic cylinder of the anvil carrier is

jammed (e.g. if resin residues are sticking to the anvil), the ball valve inside the

penstock (pressure pipe) towards the anvil is to be shortly opened. This effects

that oil is being pumped under the anvil carrier loosening it from the anvil. During

operation this ball valve must always be closed.

- Loosen tension wedge by means of the masked tension/pressure bolts. Introduce

ISK key into cover plates at the backside of the carrier.

- Screw back set screws for anvil.

Introduce ISK-key into the rear side of the carrier.

- Remove anvil by pulling it laterally out of the carrier. Do not remove the stops.

- Insert new or reground anvil and tighten the set screws lightly. It is imperative that

the clamping surfaces are absolutely clean.

- Tighten wedge by means of the push/pull screw (For required torque see “Techni-

cal data“).

- Move anvil carrier laterally into the machine by activating the button „Anvil in“.

- Remount holding plates by tightening set screws against plates (for required

torque see technical data) prior to tightening the bolts securing the holding plates.

Set screws must be secured with locknuts.



- Rotate rotor by hand for one full revolution, prior to restarting the chipper.



8 INSPECTION AND MAINTENANCE

8.1 General comments

• Every person concerned with installation, start-up, operation and mainte-

nance of the chipper must have read and understood the complete man-

ual, in particular the section „safety instructions“. The user is advised to

have this confirmed by signature of the appropriate personnel.

• Regular maintenance must only be performed with switched off (locked

out) motors.

• Prior to commencing any work on the machine it must be locked out ac-

cording to the appropriate rules and regulations.

• Any bolted connection that was loosened in the course of maintenance

work must be checked after eight hours running time.

• Due to the strong vibrations during operation, all bolted connections

must be regularly checked and tightened if required.

• Any bolts and nuts that become unusable must be replaced with the

same type and grade.

• Due to widely varying operating conditions of chippers, it cannot be pre-

dicted how often regular checks and maintenance will be required. The

user must establish those intervals with due consideration to operating

conditions prevailing at the user's operation.

abridged respectively.



8.3 Knives

8.3.1 Knife grinding

Always use cut resistant gloves when handling knives.

The knives are manufactured of high grade alloy steel and must always be ground

with adequate coolant. Overheating will cause localised reduced hardness or cracks

and tensions which can cause knife to break.

8.3.1.1 Grinding of knives

The knives should be kept in sets for regrinding. After grinding the knives in a set

should have the same width; this will prevent rotor imbalance.

The knives must be ground to the angles shown in the following tables.

The knives must be ground on the surface shown by shading. The shading also indi-

cates maximum extension of grinding permitted.

Concave grinding surfaces must be prevented, use a grinding stone to remove any

burrs.

When the knives have been reduced to the minimum width they must not be used

anymore and have to be replaced by new knives. Replace knives always in sets.



8.3.1.2 Grinding of counter knives

Grinding angles are shown in the following tables.

The anvil must only be ground on the surfaces indicated by shading; shading also

indicates maximum grinding allowance.

Use a grinding stone to remove any burrs.

When the anvil has been reduced to the minimum width it must not be used any-

more; replace it with a new anvil.



8.3.2 Knife setting

The knife setting is adjusted outside the machine in the supplied knife jig.

Adjust knives as follows:

- Set knife with adjusting pieces in knife jig as shown.

- Loosen set screws in adjusting pieces.

- Move adjusting pieces against stop.

- Tighten set screw in adjusting pieces.

- Remove knife from jig.



8.3.3 Re- adjusting the jig

On machines equipped with bolted anvils, the grinding of the anvil moves the position

of the knife edge and the knife jig must be adjusted for the new dimension "X". For

this purpose a knife adjusted for the old dimension "X" is mounted in the chipper and

with a feeler gauge the gap between knife and anvil is measured. Then the stops of

the knife jig are changed, so that the dimension "X" of the jig corresponds with the

dimension "X" of the chipper.

Knife clearance between anvil and knife 0,3 - 0,5 min.

This adjustment of the knife jig is not required with machines with clamped anvils; af-

ter grinding of the anvil the cutting edge of the anvil moves automatically into the old

position.

8.4 Hydraulic plant

please refer to the separately attached documentation’s of our sub-suppliers.

8.4.1 Accumulator (only for hydraulic plant of the chipper)

8.4.1.1 Oil pressure p3

The oil pressure in the accumulator must be checked daily. After starting hydraulic

pump with the push-button „pump on“ the lever of the ball valve is moved to the posi-

tion „charge accumulator“. The pressure gauge of the accumulator shows the in-

creasing pressure. When the pressure indicated on the hydraulic diagram is reached

the lever is moved back into operating position. If the pressure should be too high, it

can be reduced by moving the lever into the position „empty accumulator“. After set-

ting the proper pressure the hydraulic pump is turned off.

The accumulator oil pressure must be adjusted with the top feedrolls in fully lowered

position.



Warning: The hydraulic pump should run only as long as necessary as extended running will

heat up the hydraulic fluid. Oil temperature over 60 deg. C is damaging to the oil; the

temperature can be checked on the combined level indicator/thermometer.

8.4.1.2 Gas pressure p1

The gas (nitrogen) pressure in the accumulator must be checked after start-up and

after repairs at least once in the first week. If no pressure loss has occurred it must

be checked again after 3 months and if that check shows no pressure loss the

checks can be done at yearly intervals.

Gas pressure is checked as follows:

- Move lever of ball valve slowly into the position „empty accumulator“.

- Slowly let the oil escape from the accumulator, while observing the oil pressure on

the pressure gauge of the accumulator.

- When the gas pressure p1 is reached, the needle of the pressure gauge drops

suddenly down to zero. The pressure noted just before the drop is the gas pressure p1. This must correspond with the value noted on the hydraulic diagram.

Following the check of p1, the oil pressure p3 must be set again as described pre-

viously (see 8.3.1.1)

Is the accumulator gas pressure too low, it will be necessary to refill the accumulator

with nitrogen. This can be done with a special fitting, which is not part of the supply. If

the user has such a fitting, the filling must be done according to the enclosed manual

for the filling of accumulators.

We recommend that this work be done at a properly equipped service centre by

qualified personnel (for instance at a Bosch service centre).



8.4.2 System pressure

Maximum system pressure must be checked daily. After starting the pump, the pres-

sure can be read on the pressure gauge on valve block. The pressure must corre-

spond with pressure indicated on the hydraulic diagram. Changing of the pressure is

done by adjusting the pressure limiting valve (see chapter „Spare part drawings and

part lists/design hydraulic aggregate“).

8.4.3 Oil tank

Check the oil level daily. If level drops below lower limit oil must be added.

Prior to adding or changing oil, lower all cylinders and empty the oilside of the accu-

mulator (lever of ball valve in position „accumulator empty“. Following this procedure,

the oil pressure p3 must be set again (see 8.3.1.1).

When adding oil, the same make and type of oil must be used. If the oil make or type

must be changed, the system must be completely emptied and flushed with the new

type of oil prior to filling the system with the new oil. This will avoid potential problems

with sticky valves.

Oil used at the factory: SHELL Tellus 46.

Used hydraulic oil must be disposed of in suitable manner; please ensure that oil

does not find its way into the sewer.

8.4.4 Filter

The filter element must be checked regularly. Initial check one week after start-up

and thereafter every three months. To check this, the red plastic cover of the filter is

removed giving access to the filter element. If it is dirty and clogged it must be re-

placed by a new one.



8.4.5 Hydraulic hoses

The hydraulic hoses must be checked regularly and, if damaged or show signs of

ageing, must be replaced.

8.4.6 Pipework

8.5 Gear motors For maintenance of the gear motors, as well as installation and operation we refer to

the attached documentation of the manufacturer.

8.6 Electrical motors For maintenance of the electrical motors, as well as installation and operation, we

refer to the documentation of the manufacturer.

8.7 Couplings For maintenance of the couplings, as well as installation and operation, we refer to

the documentation of the manufacturer.

8.8 Belt drive

8.8.1 V-belt

Proper belt tension is very important to achieve full power transmission and long life.

Too much or inadequate tension will result in short belt life; too much tension will also

result in bearing overload.

- The belt tension must be checked regularly, and adjusted if necessary.

- After a new set is installed, the tension must be checked after 4 or 5 hrs. running

time, and adjusted if necessary.

- No belt wax or compound must be used.



- In order to check or change the belts, the belt guard must, if necessary, be re-

moved. This must only be done with the machine at a standstill and a locked out

motor. After completion of the work, the guard must be replaced immediately.

- When changing belts, the centre distance must be reduced, so that the belts slip

on easily. If the belts are forced on by rotating the sheave, damage to the belts can

occur, as well as injury to the hands; the high moment of inertia makes fast stop-

ping of the sheave by hand impossible.

8.8.2 Flat belts

Flat belts do not require maintenance.

Checks for tension are not required.

However, should the belt be removed or changed for any reason, it is important that

the belt be re-installed with the correct tension.

In order to check or change the belt, the belt guard must, of necessity, be removed.

This must only be done with the machine at a standstill and a locked-out motor. After

completion of the work, the guard must be replaced immediately.

8.9 Chain drive Chains running in completely enclosed chain cases require new grease once a year.

At this time the case should be thoroughly cleaned and filled with new grease. To

change grease only partially is not recommended.

Chains running in open chain guards require lubrication once a day with oil applied

with oil can or brush.

Kette4.cdr



The chain should be cleaned regularly.

To clean the chains, brush with a coarse brush to remove any dirt. Wash the chain in

benzene, kerosene or similar solvent and soak it in this for 24 hrs. After this the chain

should be clean, if it is, it will no longer make any scratching sounds when the links

are moved.

In order to lubricate the chain, it should be submersed in a bath of good quality motor

oil and moved around.

Prior to re-installation the sprockets must be cleaned thoroughly.

8.10 Rotor wear plates (optional) The wear plates (counter knives) underneath the knives should be observed at every

knife change. They must be replaced before the wear reaches the rotor body. These

wear plates must be changed as a set, to prevent rotor imbalance.

8.11 Feedrolls The wear of the feedroll teeth should be observed, short round teeth affect the indeed

and therefore the chip quality. The two feedrolls just ahead of the rotor show usually

the strongest wear.

In order to fully utilise the life of all feedrolls, they can be exchanged with other rolls

showing less wear. There are two types of feedrolls and any roll must be replaced by

a roll of the same type.

The cleaning comb installed between rotor and lower first feedroll usually experi-

ences a lot of wear and must be replaced when worn. The cleaning comb on the up-

per feedroll does not usually receive a lot of wear.



8.12 Screen The screen should be checked at fairly large intervals.

Broken bars, due to wear or foreign material, increase the openings. This will result in

larger chips and overs escaping. A damaged screen should be replaced immediately

with a new one.

8.13 Lubrication Careful lubrication ensures troublefree operation of the drum chipper.

- All lubrication must be performed with the machine at a standstill.

- Lubrication is to be performed as per attached lubrication schedule with the listed

lubricants.

- Lubricants of different makes but same type and properties can be used.
