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.
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.
Purge Pump of Air and
Contaminants
To remove air from the pump, follow these steps:
• Set up the pressure washer as described in
“Preparing the Pressure Washer for Use” on page 5.
• Connect and turn ON the water supply.
• Pull the trigger on the spray gun and hold.
To remove contaminants from the pump, follow
these steps:
• Set up the pressure washer as described in
“Preparing the Pressure Washer for Use” on page 5.
• Remove the nozzle extension from the spray gun.
• Connect and turn ON the water supply.
• Start the engine according to instructions given in
“How to Start Your Engine” on page 8.
• Squeeze the trigger on the spray gun and hold.
• When the water supply is steady and constant,
engage the safety latch and refasten the nozzle
extension.
Check Chemical Injection Tube
Examine the filter on the detergent hose and clean if
clogged. The tube should fit tightly on the barbed
fitting. Examine the tube for leaks or tears. Replace
the filter or tube if either is damaged.
Cleaning Chemical Injection Tube
If you have used the chemical injection tube you must
flush it with clean water before stopping the engine.
• Place the chemical injection tube in a bucket full of
clean water.
• 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.
Nozzle Maintenance
If a nozzle becomes restricted or clogged with foreign
materials, such as dirt, excessive pump pressure may
develop. This condition is indicated by a “pulsing”
sensation during use.
If the nozzles become clogged or partially restricted,
immediately clean the nozzles 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).
Use wire here
to remove
debris.
