Refer to Figure 13 and service the in-line filter if it
becomes clogged, as follows:
1. Detach spray gun from high pressure hose.
Detach nozzle extension from spray gun and
remove o-ring and screen from nozzle extension.
Flush the screen, spray gun, and nozzle extension
with clean water to clear debris.
2. If the screen is damaged, the o-ring kit contains a
replacement in-line filter screen and an o-ring. If
undamaged, reuse screen.

of the nozzle extension. Direction does not matter.
Push the screen in with the eraser end of a pencil
until it rests flat at the bottom of the opening. Take
care to not bend the screen.

snugly against the in-line filter screen.
5. Assemble the nozzle extension to the spray gun,
as described earlier in this manual.
