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 lance. 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 lance to the spray gun, as described
earlier in this manual.
Check Detergent Hose
Examine the filter on the detergent hose and clean if
clogged. Hose should fit tightly on barbed fitting.
Examine hose for leaks or tears. Replace the filter or
hose if either is damaged.
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 dual lance 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 dual lance 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 dual lance.
Cleaning Chemical Injector Hose
If you have used the chemical injector hose you must
flush it with clean water before stopping the engine.
To clean the chemical injector hose:
Place the small filter end of the chemical injector
hose in a bucket of clean water.
Open the chemical valve handle fully on the lance
by turning it counterclockwise. This puts the gun in
low pressure.
Squeeze the spray gun trigger for 1 to 2 minutes to
flush the chemical injector hose.
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 water
pressure in the hose.
Nozzle Maintenance
If the nozzle on the dual lance 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
nozzle.
If the 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.
Press trigger to relieve pressure.
Separate the dual lance from the gun.
Use the wire included in the kit (Figure 14) or a
small paper clip to free the foreign materials
clogging or restricting the nozzle.
