General Recommendations
Regular maintenance will improve the performance and
extend the life of the pressure washer. See any qualified
dealer for service.
The pressure washer’s 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 pressure washer as instructed in this manual,
including proper storage as detailed in Winter Storage and
Long Term Storage.
NOTE: Should you have questions about replacing
components on your pressure washer, please call
(800) 743-4115 for assistance.
Some adjustments will need to be made periodically to
properly maintain your pressure washer. Check the
spray gun and nozzle extension assembly for wear.
All maintenance in this manual and the engine
operator’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. 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 operator’s manual for more details.

Pressure Washer Maintenance
Clean Debris
Daily or before use, clean accumulated debris from cleaning
system. Keep linkage, spring and controls clean. Keep area
around and behind muffler free from any combustible debris.
Inspect cooling air slots and openings on the pressure
washer. These openings must be kept clean and
unobstructed.
Cleaning system parts should be kept clean to reduce the
risk of overheating and ignition of accumulated debris.
Use a damp cloth to wipe exterior surfaces clean.
Use a soft bristle brush to loosen caked on dirt, oil, etc.
Use a vacuum cleaner to pick up loose dirt and debris.
Check and Clean Inlet Screen
Examine the screen on the pump’s 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.
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.
Check Gun and Nozzle Extension
Examine the hose connection to the spray gun and make
sure it is secure. Test the trigger by pressing the red button
and making sure the trigger “springs back” into place when
you release it. You should not be able to press the trigger
without pressing the red button. Replace spray gun
immediately if it fails any of these tests.

shorten its life.
