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 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).
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. Engage trigger lock on spray gun and 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
Purchase an O-Ring / Maintenance Kit, Model 6048, by
contacting the nearest authorized service center. It is not
included with the pressure washer. This kit 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.

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.
