22 Small repairs -
The pressure gauge shows full pressure although the gun has
been closed. The pressure switch valve switches constantly.
In case of a leakage there is no guarantee for possible
consequential damages.
do it yourself!
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 pres-
sure 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 press the
trigger of the gun to decrease the pressu-
re.
Unscrew HP hose, gun and lance and
check the O-rings.
If the O-rings are damaged they have to
be replaced.
