using the tools included with your pressure washer and
follow these instructions:

from the end of the nozzle extension (Figure 21).

Remove the in-line filter from the other end of the
nozzle extension.
4.
Use the wire included in the kit (or a small paper clip)
to free any foreign material clogging or restricting the
nozzle (Figure 21).
5.
Using a garden hose, remove additional debris by back
flushing water through the nozzle extension
(Figure 22). Back flush between 30 to 60 seconds.Turn
the adjustable nozzle extension to stream spray and
move the nozzle from low to high while flushing.
