Check In-Line Filter
Refer to Figure 13 and service the in-line filter if it
becomes clogged, as follows:
1. Detach gun and nozzle extension from high pressure
hose. Detach nozzle extension from gun and remove
o-ring and screen from nozzle extension. Flush the
screen, gun, and adjustable 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.
3. Place the in-line filter screen into the threaded end 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.
4. Place the o-ring into the recess. Push the o-ring snugly
against the in-line filter screen.
5. Assemble the nozzle extension to the spray gun, as
described earlier in this manual.

Nozzle Maintenance
If a nozzle becomes restricted or clogged with foreign
materials, such as dirt, excessive pump pressure may
develop. A pulsing sensation occurs during use. This
generally is not a pump related problem, but rather a
clogged or partially restricted nozzle.
If a nozzle become clogged or partially restricted,
immediately clean it with the kit included with your
pressure washer by following these instructions:
• Shut off the engine and turn off the water supply.
• Remove the nozzle from the end of the nozzle
extension.
• Use the wire included in the kit or a small paper clip to
free the foreign materials clogging or restricting the
nozzle (Figure 14).
• Remove additional debris by rinsing out the nozzle. Rinse
between 30 to 60 seconds.
• Reinstall the nozzle into the nozzle extension.
• Reconnect the water supply, turn on the water, and start
the engine.
• Test the pressure washer.
