Dirt in the suction filter
Unscrew filter basket and clean.
Possibly clean it with
compressed air
Nozzles are clogged
Flow nozzle and end plug is
dismounted and cleaned. The
nozzle pipes are cleaned. Check
all hoses for dirt. Make sure the
hose couplings are tight so the
pump does not take in ”false” air.
Spring in overpressure valve is
not tensioned enough
Open all nozzle valves. Take
overpressure valves out of the
container. If a lot of liquid comes
out the spring must be tensioned
(prolonged)
D. Motor for pump drops out

are cleaned. When assembling
the overpressure valve the grey

app. 10 min. before the motor for
the pump is reset.
