Troubleshooter
Problem:
No water from nozzle although the high-pressure cleaner
is running. The stainless steel pressure gauge shows full
pressure.
Cause:
Most likely the nozzle is blocked.
The stainless steel pressure gauge shows full pressure,
but from the nozzle comes only little water or no water at
all.
(Inside the stainless steel pressure gauge is no water but
a filling with glycerin to damp the vibration of the poin-
ter.)
Problem:
Irregular jet from nozzle. The stainless steel pressure
gauge shows low pressure.
Cause:
Most likely the valves are soiled or sticky.
The stainless steel pressure gauge shows low pressu-
re despite fully turned up pressure regulation. The water
from the lance comes in squirts. The high-pressure hose
vibrates.
(Inside the stainless steel pressure gauge is no water but
a filling with glycerin to damp the vibration of the poin-
ter.)
Proceeding:
Switch off the high-pressure cleaner. Pull plug from the
socket. Operate safety trigger gun catch several times to
decrease the pressure.
Remove safety trigger gun and lance first, then rinse
high-pressure hose to remove possible soiling.
Check water inlet filter for soiling.
If the problem still exists, take wire (paper clip) and push
through nozzle opening. If this procedure is not success-
ful, the nozzle has to be replaced.
Pull plug from socket prior to starting any repair
work!
Proceeding:
Unscrew all 6 valves, one after the other (hexagonal
brass screws, 3 in a row, vertically and horizontally).
Take out valve body and O-ring by means of needle nose
pliers. Check O-ring for damage. In case of a damage the
O-ring has to be replaced.
Take a wire (paper clip) and clean valves under running
water.
Do not forget the O-ring during reassembly!
