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.
NOTICE
Improper treatment of pressure washer can damage it
and shorten its life.
• DO NOT insert any objects through cooling slots.
• 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.
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.

WARNING
Check Detergent Siphoning Tube
Examine the detergent reservoirs and detergent siphoning
tube and clean if clogged. The tube should fit tightly on the
barbed fitting of the pump and detergent shut-off valve.
Examine the tube for leaks or tears. Replace the reservoir or
tube if either is damaged.
Check Spay Gun and Nozzle Extension
Examine the hose connection to the spray 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
trigger lock in the ON position and test the trigger. You
should not be able to press the trigger.
Check In-Line Filter
Service the in-line filter if it becomes clogged, as follows:
A
1. Detach spray gun and nozzle extension from high
pressure hose. Detach nozzle extension (A) from spray
gun and remove o-ring (C) and screen (B) from nozzle
extension. Flush screen, spray gun, and nozzle
extension with clean water to clear debris.
2. Place in-line filter screen into threaded end of nozzle
extension. Direction does not matter. Push screen in
with eraser end of pencil until it rests flat at bottom of
opening. Take care not to bend the screen.
3. Place o-ring into recess. Push o-ring snugly against
in-line filter screen.
4. Assemble nozzle extension to spray gun, as described
in Assembly section.
