Small repairs - do it yourself!
The pressure gauge shows full pressure although the gun has
been closed. The pressure switch valve switches constantly.
Possible cause no.1: Leakage
Having closed th gun, the HP cleaner must
shut down and the pressure gauge must
show „0“ bar.
If the pressure gauge still shows full
pressure and the motor constantly
switches on and off, the possible reason
for this can be a leakage of the pump, the
HP hose or the lance.
Proceeding:
Check the connections from the HP clea-
ner to the the HP hose, from the hose to
the gun and also the connection between
lance and gun for tightness.
Switch off the cleaner. Shortly pull the trig-
ger of the gun to decrease the
pressure.
Unscrew HP hose, gun and lance and
check the O-rings.
If the O-rings are damaged they have to
be replaced.
Caution! In case of a leakage there is no guarantee for
possible consequential damages.
