16 Inspection and Maintenance
16.2 Inspecting and Maintaining the Pressure 
Washer
WARNING
Before carrying out any of the maintenance work specified in 
this chapter @ 6, take certain measures to reduce the risk 
of personal injury from unintended activation: switch off the 
pressure washer and disconnect the unit from the power 
supply. Relieve all system pressure and lock the spray gun 
trigger.
Proper maintenance of the pressure washer includes the 
following activities:
► Inspecting hoses, couplings, connectors and gaskets 
periodically and having a worn component replaced.
► Having worn, missing or damaged safety labels replaced 
by an authorized STIHL servicing dealer.
The pump is pre-filled with pump oil and does not require 
replacement or maintenance.
If you make a warranty claim for a component that has not 
been serviced or maintained properly, coverage may be 
denied.
16.3 Lubricating the Gaskets
To lubricate the gaskets:
► Grease the gaskets (1) with food-safe fitting grease.
