no water but a filling with glycerin to damp
the vibration of the pointer.)
Proceeding:
Switch off the high pressure cleaner. Pull
plug from the socket. Operate safety trigger

pressure.
Unplug trigger gun with safety catch and
lance first, then rinse high pressure hose to

this procedure is not successful, the nozzle
has to be replaced.
