• Press the spray gun lever (15) and wait for a continuous jet of water to come through which means
the pump is priming correctly.
• Move the master switch (1) to "0" position and close the water supply tap.
• Press the spray gun lever (15) to discharge any residual pressure.
• Connect the lance hose (22) to the spray gun (17), tightening it firmly. Operation C in Fig. 13.
• Ensure that the nozzle holder head (23) or device (39) is not in the detergent dispensing / low pressure
position as in Fig. 8-a (see also the "Operation with detergent" paragraph).
• Open the water supply tap, if any.
• Start the high pressure cleaner again moving the master switch (1) to "1" position.
• Press the spray gun lever (15) checking that the nozzle spray is uniform and there are no drips. Wait
for a continuous jet of water to come through.
• If necessary, regulate pressure by way of the pressure adjustment knob (8). Turn it clockwise to increase
pressure, anticlockwise to reduce it. You can see the pressure on the pressure indicator (9). Operation A
in Fig. 10.
NOTE: To reduce pressure, nozzle holder head (23) or device (39) can be used, proceeding as in Fig. 8-a
only with ejector kit (38) connected (see also the "Operation with detergent" paragraph).
The recommended detergents are more than 90% biodegradable. On how to use the detergent please
refer to the instructions given on the detergent pack label.
• Move the master switch (1) to "0" position.
• Fix the free end of the detergent suction hose (28) to the detergent suction fitting (11) of the ejector
kit (38) with the clamp (27) provided. Operation G in Fig. 13.
• Connect the quick coupling of the ejector kit (38) to the water outlet fitting (12), screw and tighten the
ring nut by hand completely. Operation F in Fig. 13.
• Connect the quick coupling (26) of the high pressure hose (25) to the water outlet fitting of the ejector
kit (38), screw in and tighten the ring nut by hand completely. Operation F in Fig. 13.
• Put the hose (28) in the tank (37) which has already been prepared with detergent to the strength
required: in this case too, follow the instructions given for the dosage on the detergent pack label.
• Turn the nozzle holder head (23) or device (39) as schematized in Fig. 8-a and then operate the spray
gun lever (15) and start dispensing detergent.
• Start the high pressure cleaner again, moving the master switch (1) to "1" position and operate the
lever (15): suction and mixing occur automatically as the water flows through.
• To stop the supply of detergent and restore high pressure operation, release the lever (15), stop the
high pressure cleaner, moving the master switch (1) to "0" position and operate on the head (23) or
device (39) as in Fig. 8-b.
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 (16). Operation S in Fig. 7.
• Releasing the spray gun lever (15) the high pressure cleaner moves to the by-pass operating mode,
and if it remains in this condition it will stop automatically after approximately 13 seconds.
The high pressure cleaner resumes normal functioning when the spray gun lever is pressed again.
