21
• Connect the lance hose (35) to the spray gun (57) depending on the type of high pressure cleaner you
have. Operation H 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 (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 find 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
