do it yourself!
Possible cause no.1: Leakage
Having closed th trigger gun with safety
catch, the HP cleaner must shut down and
the pressure gauge must show „0" bar.
If the pressure gauge shows full pressure but
the motor constantly switches on and off,
a leakage at the pump, at the high-pressure
hose, at the trigger gun or at the lance can
be the reason.
Proceeding:
Check connections from the HP cleaner to the
high-pressure hose and from the hose to the
trigger gun and also the connection between
lance and trigger gun for tightness.
Switch off the cleaner. Shortly press the
trigger of the trigger gun with safety catch
to decrease the pressure.
Unscrew HP hose, trigger gun with safety
catch and lance and check the O-rings.
If the O-rings are damaged they have to
be replaced.
