The environmental policy of ALTOALTO has made it a natural part of the concept of the com-

pany to reduce the effect on our environment as much aspossible. This plan is effected through a constant developmentin all branches of the company so that the greatest number ofelements in our high pressure washers affects the environmentto a minimum.

This product too is characterised by the attitude of ALTOtowards the environment.

The majority of the incorporated plastic components and firstand foremost, the cabinet, is made of the environmentallydesirable polypropylene plastic material. The applied form ofthe substance can be regranulated, which means that thesubstance can be reused upon discarding.

To ensure the possibilities of recycling theplastic materials of the product, they have beenmarked with a recycling symbol and the type ofmaterial.

It is also a part of our concern for environmen-tal problems that the high pressure washer ismaintenance-free, meaning that the oil in the high pressurepump will not have to be changed. The oil is in a closed systemand is only changed by an eventual servicing.

For the production of this high pressure washer the latesttechniques and technology have been applied. The consump-tion of unnecessary subsidiary materials has been minimized,and during the final test of the product the test water is recy-cled.

United Kingdom: Health and safety at Work Act 1974 Guidance Note P.M. 29It has always been the ALTO policy to ensure that all ALTO products are safe and without risk to health or safetywhen properly used.ALTO always endeavour to provide customers with every available item of information on the product they areusing by the issue of descriptive instruction manuals, literature and brochures which are constantly beingupdated and reviewed.If you have any doubts or problems please do not hesitate to contact ALTO Customer Services on01768 868995 or write to ALTO Consumer Products, Gilwilly Industrial Estate, Penrith, Cumbria, CA11 9BN.

2.1 Starting-upUpon the unpacking of your machine please check it for any defects. If you find any, we kindly ask you tocontact your ALTO distributor.Check the electric cable

The insulation of the electric cable should be in a safe condition.Please contact a qualified electrician or the nearest ALTO distributor if any doubts arise.

Check the voltageCheck that the voltage stated on the model tag corresponds to your mains voltage.

Power consumption, fuseCheck the power consumption stated on the model tag and then check correct prefuse.

Mains power connectionFaulty connection of the machine can cause electric shock.

1. Only connect the machine to an installation with earth connection.2. If you are in doubt about connections, please contact a qualified electrician for correct installation.3. We recommend you to connect the machine to a power source with a Residual Current Device (RCD),

which will disconnect the power supply if the leakage current exceeds 30 mA for 30 milli seconds.4. The electric supply connection shall be made by an qualified electrician and comply with the latest edition

of the IEC Wiring Regulations.

Extension cableIf you want a wider radius of action ALTO recommend you to use an extension hose instead of an exten-sion cable. If you want to apply an extension cable when operating a three-phase high pressure washer,we recommend you to use the cable dimensions mentioned below: (The use of the stated cable dimen-sions implies that the mains voltage is stable and corresponding to the voltage stated on the model tag.)

Note: If an extension cable is required it must be earthed and connected through the plug to theearth cable of your supply network in accordance with prescribed safety regulations.

5. Extension cable, plug and socket should be waterproof.6. Always use a cable similar to the one mounted on the machine i.e. with earth connection and for outdoor

use. If you are in doubt, please contact a qualified electrician or the nearest ALTO distributor.7. Cable connections should be kept dry and off the ground.8. Check extension cables before usage. Don’t use damaged cables.

2.2 OperationThis machine produces a high pressure jet and operation contrary to the instructions can cause severe injury!For your own and the safety of others the following precautions should always be observed:

1. WARNING! Never direct the water jet towards people, pets, electric wiring, or the machine itself.2. WARNING! Never try to clean clothes or footwear on yourself or other persons.3. We recommend you to wear goggles during operation.4. Never work barefoot or with sandals.5. Operator and anyone in immediate vicinity of the site of cleaning should take

action to protect himself from being struck by debris dislodged during operation.6. According to regulations persons under the age of 18 must not operate cleaning machines with a working

pressure above 70 bar (applies to this machine).7. The machine should be placed as far away from the cleaning site as possible.8. Only let instructed personnel operate the machine.9. Don’t start the machine until the high pressure hose has been correctly mounted.

10. Spray handle and lance are affected by a backward force (thrust) during operation - thereforealways hold the spray lance firmly with both hands.

Safety precautions and warnings GB

11. When pausing during operation, stop the machine by turning the start/stop button to pos. O and securethe spray handle against inadvertent use by locking the trigger with the locking device.

12. Only activate the trigger by hand. Never tie it up or fix it in any other way.13. Avoid damage to the high pressure hose such as running over by a car, squeezing, pulling, knotting/

kinking etc. and keep it away from oil and sharp or hot objects, as such may cause the hose to burst.14. Danger of scalding! Never dismount the high pressure hose or the water inlet hose while the machine is

in operation. Disconnect the cleaner, shut off the water supply and activate the spray handle beforedismounting the high pressure hose or the water inlet hose.

15. Never jerk the cable to disconnect the plug from socket.16. Always disconnect the plug from socket prior to disconnecting any extension cables.17. Avoid damage to the electric cables such as running over by a car, squeezing, pulling, knotting etc. and

keep them away from sharp or hot objects.18. According to the legislation in many countries it is forbidden to use the machine in an environment where

there could be a danger of explosion. If any doubt arises, please contact your local authorities.Important! OFFSHORE: Never use the machine in an environment where there could be a danger of

explosion (according to EN-50014).19. WARNING! High pressure hoses, nozzles and connections are important for safety when operating the

machine. Only use the high pressure hoses, nozzles and connections prescribed by ALTO.20. For safety reasons only use original ALTO accessories and spare parts.21. In icy conditions never start the cleaner until machine, hoses and accessories have thawed. Otherwise

the machine could be damaged.22. The cleaner should not be covered during operation.

2.3 Safety devices on the machineAutomatic start/stop (only 30CA)The machine is fitted with a start/stop function, which automatically switches off the machine when thespray handle is closed or if a nozzle is blocked. The start/stop function ensures that the pressure will neverexceed the working pressure by more than 20 bar. At this pressure the machine will automatically stop.

Circulation valve (safety valve) (only 30C COMPACT �)The pressure side of the high pressure pump is fitted with a circulation valve (safety valve). This valvecirculates the water back to the suction side of the pump when the spray handle is closed or if a nozzle isblocked. The circulation valve has been constructed as a safety function ensuring that the pressure willnever exceed the working pressure by more than 20 bar. At this pressure the circulation valve will auto-matically switch from high pressure to circulation mode.The pump will overheat if it is not disconnected within 5 min. and thus it may be damaged (only 3 min. at50°C). The circulation valve ensures that the machine becomes devoid of pressure when it is stopped.

Motor protectionThe electric motor features an overcurrent release for protection of motor against overloading. In the caseof increased power consumption (maloperation) the power for the motor will automatically be disconnected.

2.4 General1. It is not allowed to clean asbestos-containing surfaces with high pressure, unless using special equipment.2. Persons under the influence of alcohol, drugs and medicine should not operate the machine.3. Never touch plug and socket with wet hands.4. WARNING! This machine has been constructed for use with ALTO detergents. The use of other

detergents or chemicals may cause problems as to the operation and the safety.5. When using detergents the instructions should always be strictly observed.6. Always unplug when cleaning and maintaining the machine.7. If the electric cable is damaged, it must be replaced by ALTO trained service personnel or a similarly

trained person to avoid a dangerous situation (NB! Type Y connection: A special tool is required for thedisassemblance of the machine).

8. Don’t use the machine if the electric cable or important parts of the equipment are damaged - i.e. safetydevices, high pressure hoses, spray handles, cabinet.

9. The user is obliged to observe all national working environment and working safety regulationsconcerning the "operation of high pressure washers".

10. The most efficient cleaning is obtained if you adjust the distance to the surface which is to be cleaned.Thus you will also avoid damaging the surface.

4.0 Fields of application and working methods GB

4.1 Fields of applicationThe most important fields of application for this product are:

Agriculture Cleaning of machinery, agricultural implements, stalls, equipment, andbuildings.

Transport Cleaning of trucks, buses, cars etc.

Light industries Degreasing and cleaning of machines, workpieces, and vehicles.

Service Cleaning of vehicles, cleaning of public paths, institutions etc.

Domestic use Car, motor cycle, boat, caravan, trailer, tiles, wood works, roofs, outhouses,

greenhouses, barbecue, garden furniture etc.

4.2 Working pressureThe high pressure washer may be used with high or low pressure at your own option.

Low pressure Is first and foremost used for application of detergents and for washing off.

High pressure Is used for cleaning.

4.3 DetergentsThe most efficient cleaning is reached with detergents in conjunction with the high pressure cleaning. Forthat purpose ALTO can offer you a series of products specially developed for high pressure cleaning,among other fields within:

Cleaning of cars, caravans, boats etc. DescalingCleaning of tiles, roofs, wood works etc. Degreasing of workpiecesCleaning of buildings, machinery, stalls etc. Disinfection

The products are water-based, without phosphates, and the applied tensides (surface active substances)comply with the present requirements for easy biodegradability.Contact your ALTO distributor for directions as to which product will fulfill your requirements.The method of application and the dosage of the individual products appear on the product labels or thedata sheet. The dosage is adjusted on the high pressure washer.

4.4 Dosing of detergentThe high pressure washer features a built-in injector enabling dosing of detergent to the water when thecleaner is in low pressure mode. With this dosing unit it is possible to vary the dosing of detergent infinitelybetween 0-5%, and thus most cleaning jobs will be covered (also see section 3.1.5).

Change from application of detergent under low pressure to cleaning under high pressure is simply effectedby switching from »low pressure mode« to »high pressure mode« on the spray lance. You will not have tomount or dismount any parts by normal use of detergent.

For foam cleaning you will have to mount the special foam injector between the high pressure washer andthe high pressure hose. Insert the suction hose of the injector into the foam detergent. Mount foam lanceon spray handle and you are now ready for foam application. Upon the application dismount the foaminjector and replace the foam lance by a spray lance and you are ready for cleaning.

Fields of application and working methods GB

4.5 Working methodsYour high pressure washer has been developed for cleaning according to the so-called »2-step method«.

STEP 1 Application of detergentSTEP 2 High pressure cleaning

In practice the working process is laid down in accordance with the actual job, but as a starting point thefollowing working method can be described for a job:

1. Apply detergent under low pressure. The dosage is chosen according to the job which is to be carried outand the adjustment is made on the dosing unit.

2. Await acting time. Let the detergent act on the dirt/surface for a short time prior to pressure cleaning -usually a few minutes.

3. High pressure cleaning. Clean all surfaces under high pressure.4. Rinse afterwards, if necessary, to make sure that residual impurities are removed from the surface.

In connection with the working process, the optimum cleaning will be reached by following these 3 piecesof advice:

Advice no. 1When using a detergent, always apply it on a dry surface. If the surface is rinsed with water at first, it maybe difficult for it to absorb the detergent, and the result is a reduced effect of the detergent.

Advice no. 2When applying a detergent on large vertical surfaces (i.e. the sides of a truck) work from below and moveupwards. Thus you will avoid the detergent running off the surface through grooves and dark streaks ap-pearing on the surface whilst cleaning.

Advice no. 3During the high pressure cleaning you should work so that the high pressure water does not run over thesurface which has not been cleaned yet. This is to ensure that there is sufficient detergent on the surfacewhen the high pressure water is applied.

5.0 Pre-priming

The cleaner is pre-priming and can take water from a tank, a stream or the like. In suction mode the waterinlet hose and the pump should be filled with water prior to starting. The suction height depends on thewater temperature. Max. suction height of 1 m is reached with cold water up to 10°C.

If there is a risk of impurities (i.e. running sands) in the inlet water, an external suction filter should bemounted beyond the internal filter of the cleaner. Contact your ALTO distributor for further information.

12

6.1 Cleaning of high pressure nozzleClogging up in the nozzle causes a pump pressure which is too high, and cleaning is immediately required.

1. Stop the cleaner and detach the spray lance.2. Carefully clean the nozzle. You may use ALTO nozzle cleaning tool no 6401654.

IMPORTANT: ONLY use the cleaning tool when the spray lance is detached!3. Flush the spray lance backwards with water.4. If the pressure is still too high, repeat items 1-3.

6.0 Maintenance GB

Your ALTO high pressure washer is maintenance-free and therefore no special qualifications are requiredfor the daily use.

However, it applies to the most exposed components that a minimum of maintenance ensures a prolongedand problem-free operation. Therefore it will be a good idea to make a habit of the following:

Before mounting the water inlet hose and the high pressure hose, the couplings should becleaned free of dust and sand.

Before mounting spray lance or any other accessory on the spray handle, the machine shouldbe started and the coupling cleaned of dust and sand.

In periods where detergents are not used, the injector system should be flushed through withpure water to avoid drying up/clogging up of soap in the system.

The water filter should be cleaned once a month or more frequently if required.

The machine should be stored in a frost-free room. If by mistake the machine freezes up, itmust not be started. Let machine, hoses and accessories thaw out before starting up.NEVER START A FROZEN MACHINE.

6.2 Cleaning of water inlet filterThe water filter (1) should be cleaned once a monthor more frequently if required. Remove the springring (2) by means of a screw driver and take out thewater filter. Loosen large persistant particles andcarefully clean the filter. Remount the water filterbefore using the machine again.

6.3 Cleaning of ventsThe machine should be kept clean so as to letcooling air pass freely to the machine vents, sidesand bottom (3). Prevent water from penetrating thecleaner through these vents.

8.0 Functional description GBHigh pressure pump, water systemThe water passes from the inlet nipple (a) through a water filter (b) and into the high pressure pump (c). The high pressure pump is a pistonpump with internal valve systems ensuring that the pump will supply an exactly measured out water volume per unit of time.The water circulates from the pump (c) to the automatic start/stop valve system (g).When the spray handle is closed or the nozzle (o) is blocked, the water will automatically be recirculated to the suction side of the pump.The circulation valve is adjusted (constructed) to open at approximately 20 bar above the working pressure. When stopped the cleaner willautomatically be devoid of pressure. The water proceeds through the detergent injector (h) which is controlled by the dosing unit (j) with filter(i) and then it passes through the outlet socket of the machine (k).It then proceeds through the hose (l) and the valve of the spray handle (m) and the valve of the spray lance (n) and finally through the nozzle(o) where the water has reached a very high speed. The pump pressure is shown on the pressure gauge (p).Electric motorThe air-cooled motor is protected against overloading, as the starter switch features an overcurrent release. This cuts out the current in theevent of a continuously high power consumption or a blocked fan.If the power for the motor is cut off because of overloading, the motor can only be restarted by activating the start button (see section 3.5).In case the motor stops because of interrupted power supply the motor can be restarted by connecting the power supply.NB: it is not permissible to change the electric system of the machine.

Lors d’un arrêt, lapression descend automatiquement. L’eau passe par l’injecteur de détergent (h), dirigé par l’injecteur/doseur (j) avec filtre (i) et elle sortensuite du nettoyeur par la tubulure d’évacuation (k).Ensuite, elle passe à travers le flexible (l) et la vanne de la poignée-gâchette (m), la vanne de la lance (n) et finalement par la buse (o) oùl’eau circule à très grande vitesse. Relever la pression à la pompe sur le manomètre (p).Le moteur électriqueLe moteur à refroidissement par air est protégé contre toute surcharge, le bouton de mise en marche étant muni d’une protection moteur.Celle-ci coupe le courant en cas d’une consommation continue à surtension ainsi que dans le cas où un rotor serait bloqué.Si le moteur est coupé à cause d’une surcharge, il doit être redémarré par le bouton de mise en marche - voir point 3.5. En cas de coupure àcause d’une coupure de courant, le moteur redémarre lors du rétablissement de l’alimentation en courant.NB : Les modifications des couplages électriques du moteur sont interdites.

8.0 Werkingsprincipe NLHogedrukpomp, watersysteemHet water stroomt via de inlaatnippel (a) door het waterfilter (b) naar de hogedrukpomp (c). De hogedrukpomp is uitgevoerd met zuigers, dieervoor zorgen dat via een intern kleppensysteem per tijdseenheid telkens een exact afgemeten hoeveelheid water wordt geleverd.Het water circuleert van de pomp (c) naar het omloopventiel met automatische start/stop functie (g).Als het spuitpistool (m) gesloten is of de nozzle (o) verstopt is, zal het water automatisch terugstromen naar de zuigzijde van de pomp.Het omloopventiel is (van fabriekswege) afgesteld op opening bij ca. 20 bar boven de werkdruk. Bij uitschakeling is de reiniger automatischdrukloos.Het water loopt vervolgens door de reinigingsmiddelen-injecteur (h) die wordt ingeregeld door de doseerknop (j) met filter (i) en verlaat daarnade machine via de hogedrukkoppeling (k). Dan door de slang (l), het pistool (m) en de lans (n) en tenslotte door de nozzle (o), waar het watereen zeer hoge snelheid bereikt. De pompdruk kan afgelezen worden op de manometer (p).ElektromotorDe luchtgekoelde motor is beveiligd tegen overbelasting, daar de schakelaar is uitgevoerd met een overbelastingsbeveiliging.Deze schakelt de stroom uit ingeval van een continu hoog stroomverbruik of een geblokkeerde rotor.Indien de elektromotor door overbelasting geen stroom meer krijgt, kan de motor alleen opnieuw worden gestart door middel van de AAN/UIT-knop (zie paragraaf 3.5). Als de motor stopt door stroomuitval kan de motor opnieuw gestart worden door de stroom weer aan te sluiten.N.B.: het is niet toegestaan het elektrisch systeem van de machine te wijzigen.
