Safety devices serve for the protection
of the user and must not be put out of
operation or bypassed with respect to
their function.
While reducing the water supply/quan-
tity regulation at the pump head, the
overflow valve opens and part of the
water flows back to the pump suck
side.
If the pulling lever on the trigger gun is
released the pressure switch turns off
the pump, the high-pressure jet is
stopped. If the pulling lever is pulled
the pump is turned on again.
The overflow valve and pressure
switch are set and sealed at the facto-
ry. Setting only by customer service.
Electrical and electronic devices often
contain components which could po-
tentially pose a danger to human
health and the environment if handled
or disposed of incorrectly. However,
these components are necessary for
the proper operation of the device. De-
vices marked with this symbol must not
be disposed of with regular household
rubbish.
