Having closed the trigger gun with safety
catch, the HP cleaner must shut down.
Failure to shut down may be caused by
leakage in the pump, the pressure switch,
the high pressure hose or the trigger gun
with safety catch.
Proceeding:
Check connections from the HP cleaner to
the high pressure hose and from the hose
to the trigger gun and also the connecti-
on 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.
