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 the 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
cleaner 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 press the
trigger 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.
In case of a leakage there is no guarantee for possible
consequential damages.
