SERVICE PRESSURE WASHER
MAINTENANCE
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 and in the engine 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 (888) 228-3068 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.
NOTICE
Improper treatment of pressure washer can damage it and
shorten its life.
• DO NOT insert any objects through cooling slots.
WARNING
The high pressure stream of water that this
equipment produces can cut through skin and its
underlying tissues, leading to serious injury and
possible amputation.
• NEVER repair high pressure hose. Replace it.
• Replacement hose rating MUST exceed maximum pressure rating of
unit.
