GENERAL MAINTENANCE
RECOMMENDATIONS
The pressure washer warranty does not cover items that
have been subjected to operator abuse or negligence. To
receive full value from the warranty, the operator must
maintain the high pressure washer as instructed in this
manual.
• Some adjustments will need to be made periodically to
properly maintain your high pressure washer.
• All maintenance in this manual and 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 gun and
nozzle extension assembly for wear. A new spark plug
and clean air filter assure proper fuel-air mixture and
help your engine run better and last longer. Please refer
to your engine owner’s manual for more details.
BEFORE EACH USE
• Check engine oil level.
• Check water inlet screen for damage.
• Check in-line filter for damage.
• Check high pressure hose for leaks.
• Check detergent siphoning tube and filter for damage.
• Check gun, nozzle extension, and nozzles for leaks.
• Rinse out garden hose to flush out debris.

MAINTENANCE
Check and Clean Inlet Screen
Examine the screen on the water inlet. Clean it if the
screen is clogged or replace it if screen is damaged.
Check High Pressure Hose
The high pressure hose can develop leaks from wear,
kinking, or abuse. Inspect the 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 the hose immediately.
WARNING! 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 Siphoning Tube
Examine the filter on the detergent tube and clean if
clogged. The tube should fit tightly on the barbed fitting.
Examine the tube for leaks or tears. Replace the filter or
tube if either is damaged.
Cleaning Detergent Siphoning Tube
If you used the detergent siphoning tube, you must flush it
with clean water before stopping the engine.
• Place the chemical injection siphon/filter in a bucket full
of clean water.
• Attach the black low pressure nozzle.
• Flush for 1-2 minutes.
• 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 gun to
relieve the pressure in the hose.
Check Gun and Nozzle Extension
Examine the hose connection to the gun and make sure it
is secure. Test the trigger by pressing it and making sure it
springs back into place when you release it. Put the safety
latch in the on position and test the trigger. You should not
be able to press the trigger.
