THERMIC 22 H - Pressure washer Lavor - Free user manual and instructions

USER MANUAL THERMIC 22 H Lavor

• Instruction manual - Use and Maintenance

• For the engine to reach its maximum power it needs at least 10 hours running-in at a load 15 to 20% lower than the machine’s maximum performance.

• The engine’s maximum power diminishes as the altitude and ambient temperature at which it is working increases (there is a drop of about: 3.5% every 305 m/1000 ft above sea level and 1% every 5.6°C/42°F above 16°C/61°F). If the high pressure water cleaner is used at a high altitude or with high ambient temperature please refer to the engine’s operating and maintenance manual to see if any precautions need to be taken.

• The declared performance refers to an atmospheric pressure of 1013 hPa at sea level and an ambient temperature of 16°C/61°F.

• If the high pressure cleaner is not connected to the water mains but takes water from a tank, in certain conditions the thermostat valve can open and prevent the complete self-priming of the pump. In these cases, t a rubber hose into the hose connection of the thermostatic valve and bring the other end of the hose to the tank from where the pump takes the water.

INSTALLATION - ASSEMBLING THE ACCESSORIES

AND FILLING THEENGINE CRANKCASE WITH OIL

• Unwind the high pressure hose (59) and screw the end without the quickt coupling onto the spray gun(57) thread and tighten well with two 22 mm xed jaw spanners (not supplied). OperationB in Fig.5.

• Connect the quickt coupling(34) to the water outlet tting(15), screw down and tighten the ring nut by hand. OperationC in Fig.5.

• Insert the gasket(49) in the water inlet tting (16) and screw the water inlet hose-end tting (11) on to it. OperationD in Fig.5.

• Fill the engine crankcase with oil, following the instructions given in the relevant operating and maintenance manual (this is not to be done on machines with Diesel engines as they are lled with oil in the factory).

OPERATION – PRELIMINARY ACTIVITIES

• Do the preliminary activities described in the operating and maintenance manual of the engine mounted on the high pressure cleaner. In particular remember to ll with fuel and check the level of engine oil. NOTE: the THERMIC model has a capacious tank(28) integrated in the high pressure cleaner frame.

• When the engine is o and the machine is completely cold, check the level of pump oil by way of the level indicator(38). Also check the gearbox oil level by way of the level indicator (44) on those models thus equipped. When topping up is needed please refer to the lubricant types given in the “SpecIFIcatIonS and technIcal data” paragraph.

• Check if the water inlet lter (23) is clean.

• Take the high pressure cleaner to the place of work using the handle(4).

• Engage the parking brake(41).

• Unwind the high pressure hose completely(59).

• Fix a supply hose with an inside diameter of 19mm/0,75in to the water inlet hose-end tting (23). Operation G in Fig.5.

• Start the engine, referring to the relevant operating and maintenance manual.

• Open the water supply tap (if connected to the drinking water mains it is mandatory to use a back-ow preventer: to use this device refer to the relevant instruction manual), making sure there are no drips. Alternatively, put a suction hose in a tank.

• Press the spray gun lever(33) and wait for a continuous jet of water to come through which means the pump is priming correctly. EN18

• Stop the engine, referring to the relevant operating and maintenance manual, and close the water supply tap, if any.

• Press the spray gun lever(33) to discharge all residual pressure.

• Connect the lance hose(35) to the spray gun (57) depending on the type of high pressure cleaner you have. OperationH in Fig.5. STANDARD OPERATION (HIGH PRESSURE)

• Start the engine, referring to the relevant operating and maintenance manual.

• Open the water supply tap, if any.

• Press the spray gun lever(33) checking that the nozzle spray is uniform and there are no drips.

• If necessary regulate the pressure by way of the pressure regulating knob(17). Turn it clockwise to increase pressure, anticlockwise to reduce it. You can see the pressure on the pressure indicator(18). CAUTION

• Before expecting maximum performance of the high pressure cleaner it is good practice to warm the engine up for a couple of minutes. STOPPING OPERATION

• When the spray gun lever(33) is released it stops the high pressure jet and the machine goes to the bypass mode.

• Pressing the spray gun lever(33) again the high pressure jet starts again. WARNING

• If you have to interrupt the high pressure jet and put the spray gun down, without stopping the machine, you have to insert the safety stop(32). Operation S in Fig.3. CAUTION

• Do not leave the high pressure cleaner for more than three minutes in bypass (spray gun closed) if the optional thermostatic valve has not been installed by a Specialized Technician. STOP

• Close the water supply tap or take the suction hose out of the tank.

• Drain the water from the high pressure cleaner, working it for a few seconds with the spray gun lever(33) pressed.

• Carry out the stop operations, explained in the engine operating and maintenance manual and take the ignition key out(43) (Diesel engines and petrol engines with electrical start-up).

• Discharge any residual pressure from the high pressure hose(59), keeping the spray gun lever(33) pressed for a few seconds.

• Wait for the high pressure cleaner to cool down. DECOMMISSIONING

• Carefully rewind the high pressure hose(30) or (59) without making any kinks in it.

• Follow the instructions for decommissioning as given in the engine operating and maintenance manual.

• The high pressure cleaner must be kept in a dry, clean place paying attention not to damage the high pressure hose. Engage the brake (41) to avoid any uncontrolled movements of the machine. NOTE: after a prolonged period of non-use you could nd a few drops of water under the pump. This dripping normally disappears after a few hours of use. If it does persist however, contact a Specialized Technician.19 ROUTINE MAINTENANCE Do the operations described in the “Stop” paragraph and follow the instructions given in the following table. Also remember to carry out the routine maintenance jobs given in the engine operating and maintenance manual, especially as regards to checking engine oil, the air lter and the spark plug. MAINTENANCE SCHEDULE JOB Every time it is used

• Check the high pressure hose, ttings, spray gun and lance hose. If one or more parts are found to be damaged do not, under any circumstances, use the high pressure cleaner and contact a Specialized Technician.

• Check pump oil level.

• Remove all dirt and debris from the cooling ns on the engine, from the air inlet grids, from the mechanisms and rev regulator springs (refer to the engine operating and maintenance manual). Weekly • Clean the water inlet lter(23). Unscrew the cap(61) and take the cartridge out(63), (see Fig.4). It is normally enough to put the cartridge under running water or blow it with compressed air to clean it. In the most dicult cases, use a scale remover or replace it, contacting an authorised assistance centre to buy the new cartridge. Mount the cartridge and screw the plug back down. Monthly • Clean the water inlet lter(23) (refer to what has been explained previously).

• Clean the nozzle. It is normally enough to put the needle (29) supplied through the hole of the nozzle to clean it. If the results are not good, replace the nozzle purchasing it from an authorised assistance centre. The professional xed fan nozzle mounted on the nozzle holder heads (24) can be replaced using a 14 mm box spanner (not supplied).

• Oil or grease the rotating or sliding parts the operator is able to reach (refer also to the engine operating and maintenance manual).

• Check soundness of the water inlet and outlet circuits.

• Check clamping of the pump to the engine and the engine to the frame. If clamping is found to be insecure do not, under any circumstances, use the high pressure cleaner and contact a Specialized Technician. CAUTION

• When working, the high pressure cleaner should not be too noisy and there should be no obvious drips of water or oil underneath it. If this is the case have the machine checked by a Specialized Technician. SPECIAL MAINTENANCE Special maintenance must only be done by a Specialized Technician, complying with the following table. Also remember to carry out the special maintenance jobs listed in the engine operating and maintenance manual. MAINTENANCE SCHEDULE JOB After the rst 50hours of operation
