Check In-Line Filter
Refer to Figure 17 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 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.

sure it springs back into place when you release it. Put the
safety latch in the ON position and test the trigger. You
should not be able to press the trigger.

Detergent Siphon Tube
If you have used the detergent siphon tube you must flush
it with clean water before storing the unit.
• Place the detergent siphon tube in a bucket full of clean
water.
• With the engine running, flush for 1–2 minutes.
• Shut off the engine.
IMPORTANT:
Simply shutting OFF engine will not
release pressure in the system. When the engine has shut
down, squeeze the trigger on the spray gun to
relieve the pressure in the hose.
