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.

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.
Check Gun and Nozzle Extension
Examine the hose connection to the gun and make sure it
is secure. Test the trigger by pressing it and making 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.
Purge Pump of Air and
Contaminants
To remove air from the pump, follow these steps:
• Set up the pressure washer as described in “Preparing
Pressure Washer For Use” (page 5). Connect the water
supply and turn water ON.
• Pull the trigger on the gun and hold.
• When the water supply is steady and constant, engage
the safety latch.
To remove contaminants from the pump, follow
these steps:
• Set up the pressure washer as described in “Preparing
Pressure Washer For Use” (page 5). Connect the water
supply and turn water on.
• Start the engine using instructions given earlier in this
manual.
• Squeeze the trigger on the gun and hold.
• When the water stream is steady and constant, engage
the safety latch and attach the nozzle extension.
Cleaning Detergent Siphoning Tube
If you used the detergent siphoning tube, you must flush it
with clean water before stopping the engine.
• Place the detergent siphoning tube in a bucket full of
clean water.
• Slide the adjustable nozzle forward to the low pressure
position. 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 gun to
relieve the pressure in the hose.
Nozzle Maintenance
If a nozzle becomes restricted or clogged with dirt or
foreign materials, a pulsing sensation caused by excessive
pump pressure may occur during use.
Immediately clean a clogged or partially restricted nozzle
with the kit included with your pressure washer by
following these instructions:
• Shut off the engine and turn off the water supply.
• Disengage the safety latch and pull the trigger on the
spray gun. Hold until all water is purged from the unit.
Engage the safety latch on the spray gun.
• Separate the nozzle extension from the spray gun.
• Twist nozzle to stream setting.
• Remove nozzle from the end of the nozzle extension
using a 2 mm or 5/64 allen wrench (included in Nozzle
Cleaning Kit) (Figure 18).
