Installation and Operating InstructionsElectric Pressure Washer

1. Oil Plug2. Pressure Adjustment Knob3. On/Off Switch4. Outlet5. Inlet6. Chemical Filter7. Chemical Regulator8. Pressure Indicator9. Oil Level Indicator10. Automatic Gun11. High-Pressure Hose12. Quick-Lance13. Multireg Nozzle

THE MACHINE MUST BE PLACED IN A HORIZONTAL POSITION, ON A LEVEL SURFACE.

Remove plug from oil cap. Check that the oil in the sight glass is atthe halfway level.

Connection of high pressure line:1. Insert the lance in the gun and turn the nut to tighten it safely (A).2. Connect the high pressure hose to the OUTLET port (B) and tighten the nut.Connection to water supply:1. The maximum temperature of the inlet water must not exceed 140oF.2. Connect the water supply to the INLET port by means of a reinforced hose (200 PSI) with internal diameter of no

less than 13 mm (1/2”).3 Considering that the water flow decreases in accordance with the length of the hose, make sure that the quantityof water reaching the machine is at least 2.7 GPM.

GENERAL PUMP A member of the Interpump Group Formula 99SElectric Pressure Washer

Connection to electrical supply:1. Make sure that the main voltage is the same as shown on the identification label on the machine.2. Make sure that the plug complies with your local regulations, and that it is provided with ground connection.3. The power outlet must be protected by a residual circuit breaker having a sensitivity of less than 30 amp.4. Do not connect other appliances to the same outlet.5. Insert the plug after making sure that the switch on the machine is in the OFF position.

WARNING: In case of power failure during operation, turn the machine OFF for safety reasons.

Starting the machine:1. Turn on the water.2. Hold the gun in the open position to allow the air to escape from the hose.3. Switch on the unit.4. At this point adjust the machine to your pressure requirement and you are ready to begin.

CHECKING AND CHANGING THE OIL- The level of the oil must be checked periodically.- The first important oil change must be carried out after the first 20 hours of work and successively every 150 hours.- In any case we suggest an oil change at least once a year.- Oil type: Series 100 GP-oil (30 wt. non-detergent)- Capacity: 11 oz.

GENERAL PRECAUTIONS FOR USE

1. Keep the machine out of the reach of children.2. High pressure water jets are potentially dangerous if used incorrectly. In particular, the jet must not be directed

against persons or animals, electrical equipment or the machine itself.DO NOT USE the machine when persons and/or animals are within the reach of the jet.

3. The user must operate the machine in safe conditions and situations avoiding any situations of potential danger tohimself or other persons. In particular the user will have to:- Avoid operating in unstable balance conditions.- Remember that the high pressure jet generates a recoil when the gun is opened. The force of this recoil is lessthan 4.5 pound-force.

- Use adequate protective clothing.- Wear protective goggles and anti-slip rubber shoes.- Avoid contaminating the environment with polluting, toxic or harmful substances.

4. This machine is build in compliance with the requirements of the current safety regulations. The use of electricalappliances involves the respect of some basic rules:- Do not touch electrical parts or components.- All operations of inspection, maintenance or repair must be made by qualified personnel only. ALWAYSdisconnect the plug before proceeding to any of the above mentioned operations.

5. Do not pull power cord to unplug. Do not pull high pressure hose to move unit.6. Before using the machine, inspect power cord to make sure it is not damaged. If it is damaged, have it replaced

by qualified personnel. Replace power cord only with a cable of the same type as the original, this can beidentified by the marking on the outer sleeve. Do not damage or effect risky repair on power cord.

7. Before using the machine, inspect high pressure hose to make sure it is not damaged. In case of replacementmake sure the new hose has at least the same specifications as the original. Technical specifications (maximumworking pressure, date of manufacture, name of manufacturer) must be marked on the outer sleeve of hose.

GENERAL PRECAUTIONS FOR USE (continued)

8. While the machine is running, do not cover it and do not place it in an enclosed space with insufficient ventilation.9. Do not leave the machine running for more than 5 minutes with the gun closed. Should it run for a longer period,

the temperature of the recirculating water will increase rapidly and could risk damaging the pump and pump seals.10. When the machine is not in use, lock gun trigger in safe position to prevent it from being opened by accident.11. For the sake of safety use only approved spare parts and accessories.

HOW TO USE ROTOCLEAN OR VARIOJET HOW TO USE THE “ROTOTEK” (OR “MULTIREG”)Fig. 1

The shape (from straight to fan)of the jet of water can beadjusted by simply turning theRotoclean or Variojet.

Fig. 2For Rotoclean only, theadjustment of the jet must becarried out with the gun in theclosed position.

A) Selection of high or lowpressure by push-pull action.The selection of the pressuremust be carried out with the gunin closed position (1).

B) Adjustment from straight (4)to fan (5) of water jet by simpleturning of the ROTOTEK.

HOW TO USE THE DETERGENT KITThe unit can suck and mix detergents and other liquid chemicalsthanks to an automatic device incorporated in the unit itself, whichis remote-controlled by operating the Rototek. The unit is equippedwith a chemical suction kit (Fig A).

- Fit the brass connector into the chemicalcontrol knob and filter into chemicalcontainer (Fig. B).

- Select low pressure with the Rototek(Fig. C)

- At this point the suction and mixing of thechemical will start automatically.

- You can regulate the quantity ofchemicals by adjusting the chemicalcontrol knob (Fig. D).

- When you wish to stop using chemicals inorder to clean or rinse, simply release thegun trigger and adjust the Rototek to highpressure.

- At this point the chemical injectionautomatically stops.

- If you foresee not using the unit for a longperiod of time, we suggest to clean thechemical suction kit with clear water toavoid chemical deposit build-up.

CHECKING THEWATER FILTER

It is important to checkthe water filter beforeusing the machine.Remember that awell-cleanedfilter means goodperformanceand long life for yourmachine.

PRECAUTIONS IN THECASE OF STORING or

FREEZINGIf the unit is to be stored in aplace where there is risk of freez-ing, or it is to remain unused formore than 3 months, we recom-mend placing some anti-freezesolution into the pump (a normalanti-freeze as used in your vehi-cle). If in doubt at low tempera-tures or any long length of stor-age time, we suggest you turn themotor with the key providedbefore starting, to release anypossibilities of blockages fromfreezing or a build-up of line scaledeposits.
