User’s manual
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 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 condi-
tions exist, replace the hose immediately.
WARNING: The high pressure stream of
water that this equipment produces can cut
through skin and its underlying tissues, lead-
ing to serious injury and possible amputation.
NEVER repair high pressure hose. Replace it.
Replacement hose rating MUST exceed maxi-
mum pressure rating of unit.
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
Examine the hose connection to the spray gun
and make sure it is secure, and make sure the
“Safety Lock” is present attached on the trig-
ger, it helps to prevent any accident jets when
in operating. Replace spray gun immediately if
it the “Safety Lock” is damage or not works.
Check Spray Wand
Occasionally, the spray wand can become
clogged with foreign materials such as dirt.
When this happens, excessive pressure can de-
velop. Whenever the pressure nozzle becomes
partially clogged, the pump pressure will pul-
sate. It should be immediately cleaned.
Nozzle Maintenance
A pulsing sensation felt while squeezing the
spray gun trigger may be caused by excessive
pump pressure. The principal cause of exces-
sive pump pressure is a spray tip clogged or re-
stricted with foreign materials, such as dirt, etc.
To correct the problem, immediately clean the
spray tip following these instructions:
1. Shut off engine and turn off water supply.
2. ALWAYS point spray gun in a safe direction,
squeeze spray gun trigger to release retained
high water pressure.
WARNING: The high pressure stream of
water that this equipment produces can cut
through skin and its underlying tissues, lead-
ing to serious injury and possible amputation.
Spray gun traps high water pressure, even
when engine is stopped and water is discon-
nected, 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
squeeze spray gun trigger, to release high pres-
sure, every time you stop engine.
3. Remove spray tip from end of nozzle exten-
sion.
4. Use a small paper clip to free any foreign
material clogging or restricting spray tip (A).
5. Remove nozzle extension from spray gun.
6. Using a garden hose, remove additional
debris by back flushing water through nozzle
extension.
7. Reinstall spray tip into nozzle extension.
8. Reconnect nozzle extension to spray gun.
9. Make sure garden hose is connected to wa-
ter inlet. Check that high pressure hose is con-
nected to spray gun and pump. Turn on water.
10. Start engine following instructions How to
Start Your Pressure Washer.
11. Test pressure washer by operating with
each quick connect spray tip.
