Maintenance
To ensure long and reliable service, carry out
the following maintenance regularly.
Regularly check for obvious defects such as
loose fixings, and worn or damaged compo-
nents.
Check that covers and guards are undamaged
and correctly fitted. Carry out necessary main-
tenance or repairs before using.
Cleaning
Never use the pressure washer without the fil-
ter or with a dirty or damaged filter. Using the
pressure washer without a filter or with a dirty
or damaged filter may invalidate the warranty.
The clear outer casing 12a on the bosch wa-
ter filter 12 allows the user to see any build-up
of sediment. To clean the filter, first unscrew
it from the machine and push a small screw
driver through the opening to remove the rub-
ber washer 12c and filter barrel 12b. Take care
not to lose them. Wash the pieces under a
tap to remove any sediment. Reassemble by
repositioning the filter barrel 12b within the
clear plastic casing 12a and push the rubber
washer 12c back into place ensuring that it
sits firmly between the filter barrel and screw
thread (Fig. 13).
Take care of your pressure washer when in
use, be sure to keep connections and acces-
sories clean. A metal cleaning pin 11 is includ-
ed with the kit enabling the user to remove any
material that may become lodged (Fig. 14).

sure hose.

using a soft brush or cloth. Do not use water,
