• Use a vacuum cleaner to pick up loose dirt and debris.
Check and Clean Inlet Screen
Examine the screen on the pump’s water inlet. Clean if it is
clogged or replace if it is torn.
Check High Pressure Hose
High pressure hoses can develop leaks from wear, kinking,
or abuse. Inspect hose before each use. Check for cuts,
leaks, abrasions, bulging of cover, or damage or movement
of couplings. If any of these conditions exist, replace 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 Nozzle Extension
Examine hose connection to gun and make sure it is secure.
Test trigger by pressing it and making sure it springs back
into place when you release it. Engage safety latch and test
trigger. You should not be able to press trigger. Replace gun
immediately if it fails any of these tests.
Check In-Line Filter
Refer to the illustration and service the in-line filter if it
becomes clogged, as follows:
1. Detach nozzle extension from gun and remove o-ring and
screen from nozzle extension. Flush screen, gun, and
nozzle extension with clean water to clear debris.
2. Place in-line filter screen into threaded end of nozzle
extension. Direction does not matter. Push screen in with
eraser end of pencil until it rests flat at bottom of
opening. Take care not to bend screen.
3. Place o-ring into recess. Push o-ring snugly against in-
line filter screen.
4. Assemble nozzle extension to spray gun, as described
earlier in manual.
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 release retained high water pressure.
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.
5. Remove in-line filter from other end of nozzle extension.
6. Use a small paper clip to free any foreign material
clogging or restricting orifice.
7. 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.

• NEVER repair high pressure hose. Replace it.
• Replacement hose rating MUST exceed maximum pressure
rating of unit.
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.
WARNING
• DO NOT insert any objects through cooling slots.
Improper treatment of pressure washer can damage it
and shorten its life.
NOTICE
• Keep high pressure hose connected to pump and spray gun
while system is pressurized.
• ALWAYS point 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.
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.
