Check High Pressure Hoses
The high pressure hoses can develop leaks from wear,
kinking, or abuse. Inspect the hoses each time before using
them. 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 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 nozzle
clogged or restricted with foreign materials, such as dirt, etc.
To correct the problem, immediately clean the nozzle
following 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.
3. Remove nozzle from end of nozzle extension.
4. Use a small paper clip to free any foreign material
clogging or restricting nozzle (A).
5. Remove nozzle extension from spray gun.
7. Using a garden hose, remove additional debris by back
flushing water through nozzle extension. Back flush
between 30 to 60 seconds.
8. Reinstall nozzle into nozzle extension.
9. Reconnect nozzle extension to spray gun.
10. Make sure garden hose is connected to water inlet.
Check that high pressure hose is connected to spray
gun and pump. Turn on water.
11. Start engine following instructions How to Start Your
Pressure Washer.
12. Test pressure washer by operating with each quick
connect nozzle.
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.

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 hoses connected to pump, hose reel 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.
