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 (starting on page 6) 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.
Cleaning Chemical Injector
System
If you have used the chemical injector system 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 12 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.
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 15) using a 2mm or 5/64 allen wrench (like
the one included in the kit).
Use the wire included in the kit (Figure 15) or a
small paper clip to free the foreign materials
clogging or restricting the nozzle.
Remove additional debris by back flushing water
supply through wand extension (Figure 16). Back
flush between 30 to 60 seconds. Turn nozzle
extension to stream spray and move nozzle forward
and backward while flushing.
