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.
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.
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 Spray Gun
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.
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 orifice
clogged or restricted with foreign materials, such as dirt, etc.
To correct the problem, immediately clean the orifice using
the tools included with your pressure washer and follow
these instructions:
1. Shut off engine and turn off water supply.
2. ALWAYS point spray gun in a safe direction, press red
button and 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, 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, press red button
and squeeze spray gun trigger to release high pressure, every
time you stop engine.

3. Remove nozzle extension from spray gun.
4. Twist nozzle clockwise to stream position. Using 2mm
allen wrench, remove orifice (A) from end of nozzle
extension.

5. Use wire (or small paper clip) to free any foreign
material clogging or restricting orifice (B).
6. Using a garden hose, remove additional debris by back
flushing water through nozzle extension. Back flush
between 30 to 60 seconds. Turn adjustable nozzle
extension to stream spray and move nozzle from low to
high while flushing.
7. Reinstall orifice into nozzle extension. DO NOT
overtighten orifice with allen wrench.
8. Reconnect nozzle extension to spray gun.
9. Make sure garden hose is connected to water inlet.
Check that high pressure hose is connected 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 nozzle in high
and low positions.
O-Ring Maintenance
Through the normal operation of your pressure washer,
o–rings are used to keep the connections of the hoses and
spray gun tight and leak–free. These o-rings may become
worn or damaged.
An O–Ring Maintenance Kit is provided with your pressure
washer which includes replacement o-rings, rubber washer
and water inlet filter. Refer to the instruction sheet provided
in the kit to service your unit's o-rings. Note that you will not
use all of the parts in the kit.
To remove a worn or damaged o–ring; use a small flathead
screwdriver to get underneath the o-ring and pry it off.
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 leaking connections with sealant of any kind.
Replace o-ring or seal.
