Before Each Use
1. Check engine oil level.
2. Clean debris.
3. Check water inlet screen for damage.
4. Check high pressure hose for leaks.
5. Check cleaning tank and detergent siphoning tube for
damage.
6. Check spray gun and nozzle extension assembly for
leaks.
7. Rinse out garden hose to flush out debris.
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 detergent siphon hose and clean if clogged. The
hose should fit tightly on the detergent shut-off valve and
pump. Examine the hose for leaks or tears. Replace the hose
if damaged.
Check Gun and Adjustable 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.
Nozzle Maintenance
A pulsing sensation felt while squeezing the spray gun
trigger may be caused by excessive pump pressure. The
principal cause of excessive pump pressure is a nozzle
clogged or restricted with foreign materials, such as dirt, etc.
To correct the problem, immediately clean the orifice
following these instructions:
1. Shut off engine and turn off water supply.
2. ALWAYS point gun in a safe direction and squeeze
spray gun trigger to release retained high water
pressure.
3. Remove orifice (
A
) from end of nozzle extension.
Separate nozzle extension from spray gun. Twist nozzle
clockwise to stream position. Using a 2mm (5/64) allen
wrench, remove orifice from end of nozzle extension.
4. Remove nozzle extension from spray gun.
5. Use a small paper clip to free any foreign material
clogging or restricting orifice (
A
).

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.
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.
Spray gun traps high water pressure, even when
engine is stopped and water is disconnected,
which can cause injury.
• Keep high pressure hose connected to pump and spray gun
while system is pressurized.
• ALWAYS point spray gun in safe direction and squeeze spray
gun trigger, to release high pressure, every time you stop
engine. Engage trigger lock when not in use.
