HOW TO USE YOUR

PRESSURE WASHER

If you have any problems operating your pressure washer,
please call the pressure washer helpline at 1-800-270-1408.

How to Start Your Engine

The best way to start your engine-powered pressure
washer for the first time is to follow these instructions
step-by-step. You may also refer to your engine owner’s
manual. This starting information also applies whenever you
start the engine after you have let the pressure washer sit
idle for at least a day.

• Place the pressure washer in an area close enough to an
outside water source capable of supplying water at a
flow rate greater than 3.3 gallons per minute.

• Check that the high pressure hose is tightly connected to
the spray gun and to the pump. See “Preparing Pressure
Washer for Use” (page 5) for illustrations.

• Make sure unit is in a level position.

• Connect the garden hose to the water inlet on the
pressure washer pump. Turn on the water.

CAUTION! Do Not run the pump without the water

supply connected and turned on. You must follow this
caution or the pump will be damaged.

• Squeeze the trigger on the gun until you have a steady
stream of water. This purges the pump of air and
impurities.

• Attach the adjustable nozzle extension to the spray gun.
Tighten by hand (Figure 8).

• Position the nozzle in the low pressure mode (see “How
to Use the Adjustable Nozzle” and squeeze the trigger
on the spray gun to relieve the air pressure caused by
turning ON the water. Water will flow out of the gun in
a thin stream.

• Continue to hold trigger until there is a steady stream of
water and no air remains in the system. This will make it
easier to pull start the engine. Release the trigger.

• Engage the safety latch to the spray gun trigger
(Figure 9).

• Position the choke to the “Full” choke position.

NOTE: For a warm engine, be sure the choke lever is in
the “No” choke position.

• Move throttle lever to “Fast” position.

• Grasp the starter grip handle and pull slowly until you
feel some resistance. Then pull rapidly to start the
engine.

• Return the starter grip handle slowly. Do Not let rope
“snap back” against recoil housing.

• If the choke was placed in the “Full” choke position to
start the engine, slowly push it to the “No” choke
position as soon as the engine warms up enough to run
smoothly.

• If the engine fails to start, review instructions given in the
engine owner’s manual.

How to Stop Your Pressure Washer

• Move throttle lever to “Stop” position.

• Squeeze trigger on the spray gun to relieve

pressure in the hose.

NOTE: A small amount of water will squirt out when you

release the pressure.

How to Use the Adjustable Nozzle

You now should know how to START your pressure
washer and how to STOP it. The information in this
section will tell you how to adjust the spray pattern and
apply detergent or other cleaning chemicals.

CAUTION! Never adjust spray pattern when

spraying. Never put hands in front of nozzle to
adjust spray pattern.

The adjustable nozzle permits you to adjust the spray
pressure and the spray pattern, as follows:

• Slide the nozzle forward to adjust the spray to low
pressure mode (Figure 10). Slide the nozzle backward to
achieve high pressure.

• Twisting the nozzle adjusts the spray pattern from a
narrow pattern to a fan pattern (Figure 10).

• Point the nozzle toward the ground and press the trigger
to test the pattern (Figure 11).

• Increase or decrease the pressure of the spray by turning
the pressure control knob counterclockwise or
clockwise respectively (Figure 12).

• For most effective cleaning, keep the spray nozzle
between 8 to 24 inches away from cleaning surface.

• If you get the spray nozzle too close, especially using high
pressure mode, you may damage the surface being
cleaned.

• Do Not get closer than 8 inches when cleaning tires.

Applying Detergent with the

Adjustable Nozzle

IMPORTANT: Use soaps designed specifically for
pressure washers. Household detergents could damage

the pump.
IMPORTANT: You must attach all hoses before you

start the engine. Starting the engine without all the hoses
connected and without the water turned ON will damage
the pump.

To apply detergent, follow these steps:

• Review the use of adjustable nozzles.

• Prepare the detergent solution as required by the job.

• Hang the detergent solution on the hook of the
wireform attached to the handle, as shown in Figure 13.

• Place the small filter end of the detergent siphoning tube
into the detergent container.

CAUTION! Keep the detergent siphoning tube from

coming in contact with the hot muffler. This will damage
the plastic tube. When inserting the filter into a cleaning
solution bottle, route the tube so as to keep it from
inadvertently contacting the hot muffler.

• Slide the adjustable nozzle forward to low pressure
mode. Detergent cannot be applied with the nozzle in
high pressure position.

• Make sure the garden hose is connected to the water
inlet. Check that the high pressure hose is connected to
the spray gun and the pump (see “How To Use Your
Pressure Washer”, page 8). Start the engine.

• Apply detergent to a dry surface, starting from the
bottom and working up.

• Allow the detergent to “soak in” for 3-5 minutes before
washing and rinsing. Reapply as needed to prevent
surface from drying.

• For washing, start at lower portion of area to be washed
and work upward, using long, even, overlapping strokes.

Pressure Washer Rinsing

WARNING! Be extremely careful if you must

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 from flowing by
simply removing detergent siphoning tube from bottle.

• 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 a temperature
between 140–145°F. When the water reaches this
temperature, the automatic cool down system engages and
cools the pump by discharging the warm water onto
the ground. This system prevents internal damage to the
pump.

PRESSURE WASHER

MAINTENANCE

Check and Clean Inlet Screen

Examine the screen on the water inlet. Clean it if the
screen is clogged or replace it if screen is damaged.

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.

WARNING! Water spraying from a leak is

capable of injecting material into skin. Inspect hose
each time before using it. Never repair a high
pressure hose. Replace it with another hose that
exceeds the maximum pressure rating of your
pressure washer.

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 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 safety
latch in the ON position and test the trigger. You should
not be able to press the trigger.

Check In-Line Filter

Refer to Figure 14 and service the in-line filter if it
becomes clogged, as follows:

1. Detach gun and nozzle extension from high pressure
hose. Detach nozzle extension from gun and remove
o-ring and screen from nozzle extension. Flush the
screen, gun, and adjustable nozzle extension with clean
water to clear debris.

IMPORTANT: Simply shutting OFF engine will not
release pressure in the system. When the engine has

shut down, squeeze the trigger on the gun to
relieve the pressure in the hose.

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
using the tools included with your pressure washer and
follow these instructions:

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

2. Detach the nozzle extension from the spray gun. Twist

the nozzle clockwise to the stream position. Using the
supplied 2mm (5/64) allen wrench, remove the nozzle
from the end of the nozzle extension (Figure 15).

start the engine.

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

O–Ring Maintenance

Through the normal operation of your pressure washer,
o–rings, which keep the connections of the hoses and gun
tight and leak–free, may become worn or damaged.

Provided with your pressure washer is an O–Ring
Maintenance Kit which includes replacement o-rings,
rubber washer and water inlet filter.

To remove a worn or damaged o–ring:

• Use a small flathead screwdriver to get underneath the

o-ring and pry it off.

ENGINE MAINTENANCE

See the engine owner’s manual for instructions on how to
properly maintain the engine.

CAUTION! Avoid prolonged or repeated skin

contact with used motor oil. Used motor oil has
been shown to cause skin cancer in certain
laboratory animals. Thoroughly wash exposed areas
with soap and water.
KEEP OUT OF REACH OF CHILDREN. DON'T
POLLUTE. CONSERVE RESOURCES. RETURN
USED OIL TO COLLECTION CENTERS.

PREPARING THE UNIT

FOR STORAGE

Water should not remain in the unit for long periods of
time. Sediments or minerals can deposit on pump parts and
“freeze” pump action. If you do not plan to use the
pressure washer for more than 30 days, follow this
procedure:

1. Flush detergent siphoning tube by placing the filter into
a pail of clean water while running pressure washer in
low pressure mode (adjustable nozzle in the forward
position). Flush for one to two minutes.

2. Shut off the engine and let it cool, then remove all
hoses. Disconnect spark plug wire from spark plug.

3. Empty the pump of all pumped liquids by pulling the
recoil handle about 6 times. This should remove most
of the liquid in the pump.

NOTE: To protect the unit from freezing temperatures,
draw RV antifreeze (non-alcohol) into the pump by pouring
the solution into a 3-foot section of garden hose connected
to inlet adapter and pulling recoil handle twice.

4. Store unit in a clean, dry area.
