MAINTENANCE
Check and Clean Inlet Screen
Examine screen on the water inlet. Clean if the
screen is clogged or replace if screen is damaged.
Check High Pressure Hose
High pressure hose can develop leaks from wear,
kinking, or abuse. Inspect hose each time before
using it. Check for cuts, leaks, abrasions or bulging of
cover, damage or movement of couplings. If any of
these conditions exist, replace hose immediately.
DANGER: Water spraying from a leak is
capable of injecting material into skin.
Inspect hose each time before using it.
Never repair a high pressure hose.
Replace it with another hose that meets
the maximum pressure rating of your
pressure washer.
Check Chemical Injecting Tube
Examine the filter on the chemical injecting tube and
clean if clogged. The tube should fit tightly on barbed
fitting. Examine the tube for leaks or tears. Replace
the filter or tube if either is damaged.
Check Gun and Dual lance
Examine hose connection to gun and make sure it is
secure. Test trigger by pressing it and making sure it
springs back into place when you release it. Put safety
latch in on position and test trigger. You should not be
able to press trigger.
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 OPER-
ATION 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 Injecting Tube
If you have used the chemical injecting tube 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 injecting
tube 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 1-2 minutes to
flush the chemical injector hose.
Shut off the engine.
Important: Simply shutting OFF engine will not release
pressure in the system. When the engine has shut
down, squeeze the trigger on the spray gun to
relieve the 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 instruc-
tions:
Shut off the engine and turn off the water supply.
Press trigger to relieve pressure.
Separate the dual lance from the spray gun.
Use the wire included in the kit or a small paper
clip to free the foreign materials clogging or restrict-
ing the nozzle (Figure 11).
