Check and Clean Chemical Injection Tube
Examine the filter on the chemical injection tube and
clean if clogged. The tube should fit tightly on barbed
fitting. Examine tube for leaks or tears. Replace the
filter or tube if either is damaged.
If you have used the chemical injection tube you must
flush it with clean water before stopping the engine.
Place the small filter end of the chemical
injection tube in a bucket of clean water.
Slide the adjustable nozzle forward.
Squeeze the spray gun trigger for two minutes to
flush the chemical injection tube.
Shut off the engine.
Important: Simply shutting OFF engine will not release
pressure in the system. When engine has shut down,
squeeze the trigger on the gun to relieve the
pressure in the hose.
Purge Pump of Air and Contaminants
To remove the air from the pump, follow these
steps:
Set up the pressure washer as described in the
ASSEMBLY section and connect the water
supply.
Remove the wand extension from the gun.
Squeeze the trigger on the gun and hold.
To remove any contaminants from the pump,
follow these steps:
Set up the pressure washer as described in the
ASSEMBLY section, and connect the water
supply.
Remove the nozzle extension from the spray
gun.
Start the engine according to instructions in
OPERATION section.
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.
Nozzle Maintenance
If the adjustable nozzle becomes restricted or
clogged with foreign materials, such as dirt, excessive
pump pressure may develop. If this nozzle becomes
partially clogged, it can cause a pulsing sensation
during use. This generally is not a pump related
problem, but rather a clogged or partially restricted
adjustable nozzle.
If the adjustable nozzle becomes clogged or partially
restricted, immediately clean the nozzle with the kit
included with your pressure washer by following
these instructions:
Shut off the engine and turn off the water supply.
Separate the nozzle extension from the gun.
Adjust the nozzle extension to the stream
position.
Remove nozzle from the end of the wand
extension (Figure 16) using a 2mm or 5/64 allen
wrench (like the one included in the kit).
Use the wire included in the kit (Figure 17) or a
small paper clip to free the foreign materials
clogging or restricting the nozzle.
Figure 16 Remove nozzle.
Figure 17 Clean the nozzle.
