SAFETY RULESATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!

Safety is a primary concern in the design andmanufacture of our products. Unfortunately, ourefforts to provide safe equipment can be wipedout by an operator’s single careless act.

In addition to the design and configuration ofequipment, hazard control and accident preven-tion are dependent upon the awareness,concern, judgement, and proper training ofpersonnel involved in the operation, transport,maintenance and storage of equipment.

It has been said “The best safety device is aninformed, careful operator.” We ask you to be thatkind of operator.

TRAINING■■ Safety instructions are important! Read allattachment and power unit manuals; follow allsafety rules and safety decal information.(Replacement manuals are available from sellingdealer.) Failure to follow instructions or safetyrules can result in serious injury or death.

■■ If you do not understand any part of this man-ual and need assistance, see your dealer.

■■ Operators must be instructed in and be capa-ble of the safe operation of the equipment, itsattachments, and all controls. Do not allow any-one to operate this equipment without properinstructions.

■■ Never allow children or untrained persons tooperate equipment.

■■ Train all new personnel and review instructionsfrequently with existing workers. A person who hasnot read and understood all operating and safetyinstructions is not qualified to operate themachine. An untrained operator exposes himselfand bystanders to possible serious injury or death.

PREPARATION■■ Always wear relatively tight and belted clothingto avoid getting caught in moving parts. Wear stur-dy, rough-soled work shoes and protective equip-ment for eyes, hair, hands, hearing, and head; andrespirator or filter mask where appropriate.

■■ Make sure attachment is properly secured,adjusted, and in good operating condition.

■■ Power unit must be equipped with ROPS orROPS cab and seat belt. Keep seat belt securelyfastened. Falling off power unit can result in deathfrom being run over or crushed. Keep foldableROPS system in “locked up” position at all times.

■■ A heavy load can cause instability in driving apower unit. Make sure the rear of the tractor isproperly counter-balanced with weights. Alwaysdrive slowly – especially around turns. An unsta-ble power unit could steer badly and possibly tipover, causing injury or death.The use of the optional rear 3 pt. ballast box isrecommended. Ask your dealer.

■■ Do not exceed the lift capacity of your loader.See loader specifications.

■■ Know your equipment's capabilities, dimen-sions, and operations before operating. Visuallyinspect your equipment before you start, andnever operate equipment that is not in properworking order with all safety devices intact.Check all hardware to ensure it is tight. Make cer-tain that all locking pins, latches, and connectiondevices are properly installed and secured.Remove and replace any damaged, fatigued, orexcessively worn parts. Make certain all safetydecals are in place and are legible. Keep decalsclean, and replace them if they become worn orhard to read.

■■ Move wheels to the widest recommended set-ting to increase stability.

■■ Do not work under raised loaders without sup-porting them. Do not use support material madeof concrete blocks, logs, buckets, barrels, or anyother material that could suddenly collapse orshift positions. Make sure support material issolid, not decayed, warped, twisted, or tapered.Lower loaders to ground level or on blocks.Lower loaders and attachments to the groundbefore leaving the cab or operator's station.

■■ Check the power unit's hydraulic system. Besure the hydraulic oil and filter have been serv-iced according to manufacturer's recommenda-tions. Refer to your power unit loader operator'smanual or dealer for any adjustments necessaryto put the hydraulic system in good workingorder.

DEALER ASSEMBLY(Models AV20H, AV20E, AV20D, AV20G)

Root Grapples are shipped completely assembled.

NOTE: Check customer’s tractor and loader for remote hydraulic outletsmounted on the front of the loader.

If customer’s equipment does not have this option, then it will be nec-essary to install hydraulic lines to the hydraulic remote outlets at the rearof the tractor.

If customer’s tractor is not equipped with hydraulic remote outlets, thenone pair must be installed.

Optional parking stands are available. Stands fit all models – order5WS811395.

Model AV20H only – The Root Grapple is packaged with the hydraulichoses coiled and tied to the hydraulic cylinder.

After removing the Model AV20H from the skid, untie the hydraulichoses and remove the three 3/8” x 3” bolts from the formed channel hoseguide. Locate the hoses into the channel and reinstall the three bolts. Thechannel holds the hoses so they will loop properly at the lower pivot point.

OPTIONAL PARKING STAND INSTALLATION

The pair of parking stands bolt on the back side of the main frame.Locate a stand about 4 inches in from the end on each side of the mainframe. See parts drawing on page 22.

Remove 1/2” carriage bolt from the clevis on the stand bracket. Installthe clevis over the 3 inch square Lower Main Frame tube. Replace thecarriage bolt and tighten.

Install the stand weldment into the bracket and pin in place. NOTE: Forthe model AV20H, install the pin in second hole location from the top ofstand weldment. For all other models, use the top hole.

HANDLING MATERIAL

Approach the material to be handled with thegrapple clamp open, when the rake frame contactsthe material, close the grapple clamp. As the load islifted, tilt the frame back and then apply hydraulicpressure to the grapple clamp a second time.Sometimes, as the load is being lifted or pulled froma pile, it will shift.

It is recommended that the Root Grapple be tiltedback when transporting. Always carry a load in a lowposition so that you have good visibility and a lowcenter of gravity.

When lifting a heavy log or tree, always lift slowlyand while the load is low to the ground, make thedecision if the root grapple is properly positioned orif the load is too big or heavy to safely handle.

If necessary, the operator must release the RootGrapple from the load and back away. Then use achain saw to cut it into lighter or more manageablepieces.

When handling a pile of posts, trees, boards, limbs,etc., it may be necessary to release the load and pickup smaller amounts.

The Root Grapple used properly, will make difficulthandling and clean up jobs easier, but it requires agood safe operator.

When picking up logs or fallen trees, make surethat you pick up in the center of the load weight.Remember that the stump end of a tree that hasbeen bulldozed out of the ground has a lot of soilattached to the roots and can be very heavy.

If you are handling stumps that have soil attached tothe roots, it is strongly suggested that you use therake points to loosen and knock the soil off. Pickingthe stumps up and dropping them a few times will alsoremove soil. Removing soil from the roots will result ina cleaner burn pile and less cleanup work later.

When approaching a pile of brush or trees, watchout for branches sticking out of pile that may contactoperator or power unit.

If operator is handling large branches or trees thatare considerably wider than the width of the powerunit, always be alert for branches of standing treesthat could snap back toward the operator.

■■ Use extreme care when working close to fences,ditches, other obstructions, or on hillsides.

■■ Keep load centered on Root Grapple andloader. Make sure all loads are secure before lift-ing. If lifting with the grapple and the loadappears to be unstable, lower the load, open thegrapple and reposition the load to attain fullstability.

■■ Be sure the load does not stick out too far infront of the grapple. A light load sticking out toofar can have the same tipping effect as a heavyload carried in close.

■■ Watch for and avoid hidden obstructions, i.e.,buried pipes, rocks, concrete piers, uneven con-crete slabs, stumps, etc., when operating.

■■ Stop power unit and equipment immediatelyupon striking an obstruction. Turn off engine,remove key, inspect, and repair any damagebefore resuming operation.

■■ Stop loader gradually when lowering or liftingloads.




■■ When on a slope, keep the load low and pro-ceed with extreme caution. Do not drive ACROSSa steep slope - drive straight up and down.

With a LOADED attachment - face the attach-ment and load uphill.With an EMPTY attachment - face the attach-ment downhill.

■■ Keep alert and watch the rear as well as thefront when working with the Root Grapple.


TRANSPORTATION■■ Always comply with all state and local lawsgoverning highway safety and lighting and mark-ing requirements.



■■ Use extreme care and reduce ground speed onslopes and rough terrain. Travel with attachmentas close to the ground as possible.

■■ Do not operate or transport equipment whileunder the influence of alcohol or drugs. Consultyour doctor about operating this machine whiletaking prescription medications.

OPERATION■■ Always sit in power unit seat when operatingcontrols or starting engine. Securely fasten seatbelt, place transmission in neutral, engage brake,and ensure all other controls are disengagedbefore starting power unit engine.

■■ Know your controls and how to stop engineand attachment quickly in an emergency.

■■ Consult local utilities before working. Knowlocation of and avoid contacting all undergroundcables, pipelines, overhead wires and other haz-ards in working area.

■■ Operate only in daylight or good artificial light.


■■ Keep hands, feet, hair, and clothing away fromequipment while engine is running. Stay clear ofall moving parts.

■■ Power unit must be equipped with ROPS orROPS cab and seat belt. Keep seat belt securelyfastened. Falling off power unit can result indeath from being run over or crushed. Keep fold-able ROPS system in “locked up” position at alltimes.


■■ Look down and to the rear and make sure areais clear before operating in reverse.
