PROBLEMS CAUSES REMEDIES
The pump does not
prime.
Suction of air. Check the integrity of the suction circuit.
Delivery line closed (e.g., spray gun closed). Reset the delivery pressure (e.g., press the spray
gun lever).
Suction circuit with choke points. Check the suction circuit (especially make sure
the suction lter is clean).
The pump fails to reach
max pressure.
Pressure adjustment knob (15) not tightened
enough.
Turn the knob clockwise until required pressure
is achieved.
Not enough water supply or priming too deep. Make sure the water supply ow rate or priming
depth is in compliance with the indications in the
“SPECIFICATIONS AND TECHNICAL DATA” paragraph.
Suction circuit with choke points. Check the suction circuit (especially make sure
the suction lter is clean).
Unsuitable conditions of use (e.g., nozzle worn,
lance in low-pressure position, etc.)
Restore the correct conditions of use.
Irregular pressure and
ow rate (pulsating).
Air suction. Check the integrity of the suction circuit.
Suction lter dirty. Clean the lter.
Not enough water supply or priming too deep. Make sure the water supply ow rate or priming
depth is in compliance with the indications in the
“SPECIFICATIONS AND TECHNICAL DATA” paragraph.
The pump has not completed priming. Prime the pump according to the indications
of the
“STANDARD OPERATION (HIGH PRESSURE)”
paragraph.
Accessory clogged (e.g. clogged nozzle). Restore the correct use of the accessory.
Too much noise. Suction circuit with choke points. Check the suction circuit (especially make sure
the suction lter is clean).
Water supply temperature too high. Keep to the temperatures indicated in the
“SPECIFICATIONS AND TECHNICAL DATA” paragraph.
Low detergent suction. Use of the accessory not in low-pressure mode
(e.g., lance not in low-pressure position).
Restore the correct use of the accessory.
Detergent metering device closed or set for
low suction.
Turn the detergent adjustment knob (16)
anticlockwise.
Use of detergent which is too viscous. Keep to uses and dilutions shown on detergent
plate.
