Check High Pressure Hose
High pressure hoses can develop leaks from wear, kinking,
or abuse. Inspect hose before each use. Checkfor cuts,
leaks, abrasions, bulging of cover, or damageor movement
of couplings. If any of these conditions exist, replace hose
immediately.
A 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 repairhigh pressure hose.Replace it.
• Replacement hoseratingMUSTexceedmaximum pressure

Check Detergent Siphonin9 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. Replacethe filter or tube if either is
damaged.

position and test trigger. You should not be able to press
trigger. Replacespray 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 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 releaseretained high water pressure.
A 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.
• Keephigh pressure hoseconnected to pumpand spraygun
whilesystemis pressurized.
• ALWAYSpointspraygun in safedirectionand squeeze spray
guntrigger,to release high pressure, e verytime youstop

3. Remove nozzle extension from spray gun.
4. Twist nozzle clockwise to stream position. Using a 2mm
(5/64) allen wrench, remove orifice from end of nozzle
extension.

Use a small paper clip to free any foreign material
clogging or restricting orifice.
.
Using a garden hose, remove additional debris by back
flushing water through nozzleextension. Back flush
between 30 to 60 seconds. Turn adjustable nozzle
extension to stream spray and move nozzlefrom low to
high while flushing.
7. Reinstall orifice into nozzle extension. DONOT
overtighten orifice with allen wrench.
8. Reconnect nozzle extension to spray gun.
9. Make sure garden hose is connected to water inlet.
Checkthat high pressure hose is connected to spray gun
and pump. Turn on water.
10. Engagetrigger lock on spray gun and start engine
following instructions How to Start Your Pressure
Washer.
11. Test pressure washer by operating nozzle in high and
low positions.
