Safety Devices
Caution
Safety devices protect the user and must not be
modified or bypassed.
Power switch
The appliance switch prevents unintentional op-
eration of the appliance.
Lock trigger gun
This lock locks the lever of the trigger gun and
prevents the inadvertent start of the appliance.
Overflow valve with pressure switch
The overflow valve prevents the permissible
working pressure from being exceeded.
If the lever on the trigger gun is released the
pressure switch turns off the pump, the high-
pressure jet is stopped. If the lever is pulled the
pump is turned on again.
High pressure hose
The high pressure hose is specially constructed
with reinforced walls to handle water pressure up
to 13 MPa (1900 psi) - it can be easily damaged
and should be stored carefully.
Do not kink.
Do not drive vehicles over the hose.
Do not expose the hose to sharp edges or
corners.
Misuse will lead to ballooning or premature fail-
ure and will invalidate warranty.
