RECOMMENDATIONS
The warranty of the high pressure washer does not
cover items that have been subjected to operator
abuse or negligence. To receive full value from the
warranty, operator must maintain high pressure
washer as instructed in this manual.
 Some adjustments will need to be made periodi-
cally to properly maintain your high pressure
washer.
 All adjustments in the Service and Adjustments
section of the engine owners manual should be
made at least once each season.
 Once a year you should clean or replace the spark
plug, clean or replace the air filter and check the

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 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.
Check Gun and Wand
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 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 five 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 the
pressure in the hose.
