Pressure Washer Rinsing

_ ARNING: Be extremely careful if you use the

pressure washer from a ladder, scaffolding or

any other relatively unstable location. Pressure

in a running washer builds as you climb. When
you press the trigger, the recoil from the initial
spray could cause you to fall. The high pressure
spray could also cause you to fall if you are too
close to the cleaning surface.

For Rinsing:

• Slide the nozzle backward to high pressure, press
the trigger and wait for the detergent to clear.

NOTE: You can also stop detergent flow by removing

detergent siphoning tube from container.

• Keep the spray gun a safe distance from the area

you plan to spray.

• Apply a high pressure spray to a small area, then

check the surface for damage. If no damage is

found, it is okay to continue cleaning.

• Start at the top of the area to be rinsed, working

down with same overlapping strokes as you used

for washing and applying detergent.

Automatic Cool Down System

(Thermal Relief)

If you run the engine on your pressure washer for
3-5 minutes without pressing the trigger on the spray

gun, circulating water in the pump can reach
temperatures between 140-145°F. The automatic cool
down system engages at this temperature and cools
the pump by discharging the warm water onto the
ground, preventing internal pump damage.

PRESSURE WASHER
MAINTENANCE

Check and Clean Inlet Screen

Examine garden hose inlet screen. 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.

_ ANGER: Never repair a high pressure hose.

Replace with hose that exceeds the maximum
pressure rating of your pressure washer.

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 illustrationand service the in-line filter if it

becomes clogged, as follows:

In-line Filter

Nozzle extension

O-ring

.

Detach nozzle extension from gun and remove o-
ring and screen from nozzle extension. Flush the
screen, gun, and nozzle extension with clean

water to clear debris.

.

If the screen is damaged, the o-ring kit contains a
replacement in-line filter screen and an o-ring. If
undamaged, reuse screen.

.

Place the in-line filter screen into the threaded end
of the nozzle extension. Direction does not matter.

Push the screen in with the eraser end of a pencil
until it rests flat at the bottom of the opening. Take

care to not bend the screen.

4. Place the o-ring into the recess. Push the o-ring
snugly against the in-line filter screen.

5. Assemble the nozzle extension to the spray gun,
as described earlier in this manual.

Purge Pump of Air and Contaminants

To remove air from the pump, follow these steps:

• Set up the pressure washer as described in the

ASSEMBLY section and connect the water supply.

• Pull the trigger on the gun and hold until a steady

extension.

Nozzle Maintenance

If the nozzle becomes restricted or clogged with

foreign materials such as dirt, excessive pump

pressure may develop. A partially clogged nozzle can
cause a pulsing condition during use. This generally is
not a pump related problem, but rather a clogged or
partially restricted nozzle.

If the nozzle becomes clogged or partially restricted,
immediately clean the nozzle with the kit included with
your pressure washer by following these instructions:

• Shut off the engine and turn off the water supply.

• Separate the nozzle extension from the gun.

• Rotate to stream setting.

• Remove nozzle from the end of the nozzle

extension using a 2 mm or 5/64 allen wrench.

11

• Use the wire included in the kit or a small paper
clip to free the foreign materials clogging or

restricting the nozzle.

Insert wire into nozzle and turn back

and forth to clear obstruction.

Remove additional debris by back flushing water
supply through nozzle extension. Back flush

between 30 to 60 seconds. Turn nozzle extension

to stream spray and move nozzle from low to high

pressure while flushing.

• Reinstall nozzle into nozzle extension. Do Not
overtighten.

• Reconnect nozzle extension to spray gun.

• Reconnect the water supply, turn ON the water,
and start the engine.

• Test the pressure washer by operating with nozzle
in the high and the low pressure positions.
