Problem
After closing the safety trigger gun the high pressure cleaner
keeps switching on and off.
Possible cause No. 1
Leckage.
In case of a leakage there is no guarantee for possible
consequential damages.
Having closed the safety trigger gun, the
high pressure cleaner must shut down.
Failure to shut down may be caused by lea-
kage in the high pressure pump, the switch,
the high pressure hose, the safety trigger
gun or the lance.
Proceeding:
Check connections from the high pressure
cleaner to the high pressure hose and from
the high pressure hose to the safety trigger
gun and also the connection between lance
and safety trigger gun for tightness.
Switch off the high pressure cleaner. Shortly
press the trigger of the safety trigger gun
to decrease the high pressure cleaner.
Unscrew high pressure hose, safety trigger
gun and lance and check the O-rings. If
the O-rings are damaged they have to be
replaced.
