Check In-Line Filter
Refer to Figure 14 and service the in-line filter if it
becomes clogged, as follows:
1. Detach spray gun and nozzle extension 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 adjustable
nozzle extension with clean water to clear debris.

replacement in-line filter screen and o-ring. If
undamaged, reuse screen.
3. Place in-line filter screen into threaded end of nozzle
extension. Direction does not matter. Push screen in
with eraser end of pencil until it rests flat at bottom of

Nozzle Maintenance
A pulsing sensation felt while squeezing the spray gun
trigger may be caused by excessive pump pressure. The
principal cause of excessive pump pressure is a nozzle
clogged or restricted with foreign materials, such as dirt,
etc. To correct the problem, immediately clean the nozzle
using the tools included with your pressure washer and
follow these instructions:
1. Shut off engine and turn off water supply.
2. Remove spray tip from end of nozzle extension.
3. Remove in-line filter from other end of nozzle
extension.
4. Use wire included in kit (or a small paper clip) to free
any foreign material clogging or restricting spray tip
(Figure 10).
5. Using a garden hose, remove additional debris by back
flushing water through nozzle extension (Figure 11).
Back flush between 30 to 60 seconds.
