washer, please call the pressure washer helpline at
1-800-222-3136.
To Start Your Pressure Washer
To start your engine-powered pressure washer for the
first time, follow these instructions step-by-step. 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
2.2 gallons per minute.
• Check that the high pressure hose is tightly
connected to the spray gun and to the pump. See
“Assembling Your Pressure Washer” 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.
• Move engine control lever to the “Start/Choke”
position.
NOTE: For a warm engine, be sure the control lever is
in the “Run” position.
• As shown in the illustration to the right, ensure the

How to Stop Your Pressure Washer
• Move control 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.
DANGER! Never adjust spray pattern when
spraying. Never put hands in front of nozzle to
adjust spray pattern.
Your spray gun is equipped with an adjustable nozzle
that permits you to change the spray pressure and the
spray pattern, as follows:
• Pushing the nozzle forward changes the spray
pressure from high to low pressure. Pulling the
nozzle back changes the pressure from low to high.
• Twisting the nozzle adjusts the spray pattern from
a narrow pattern to a fan pattern.
• Point the nozzle toward the ground, disengage the
safety latch, and press the trigger to test the
pattern.
• 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 chemicals 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 the adjustable nozzle.
• Prepare detergent solution as required by the job.
• Hang the detergent solution container on the hook
attached to the handle.
• Place the filter end of the detergent siphoning tube
into the detergent container.
CAUTION! When inserting the filter into the
detergent container, route the tube so as to
keep it from inadvertently contacting the hot
muffler.
• 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. Start
the engine.
• Attach the nozzle extension to the spray gun. Slide
the adjustable nozzle forward to low pressure
mode. Detergent cannot be applied with the nozzle
in high pressure position.
• Apply detergent to a dry surface, starting from the
bottom and working up.
• Allow the detergent to “soak in” for 3-5 minutes
before rinsing. Reapply as needed to prevent
surface from drying.
• Start at lower portion of area to be washed and
work upward, using even overlapping strokes.
IMPORTANT: You must flush the chemical injection
system after each use by placing the filter into a clean
bucket of water and running the pressure washer in
low pressure for 1-2 minutes.
Twist nozzle counterclockwise for fan pattern.
Twist nozzle clockwise for
narrow spray pattern.

Pressure Washer Rinsing
WARNING! 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
cools the pump by discharging the warm water onto the
ground, preventing internal pump damage.

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 spray gun.
• Rotate to stream setting.
• Remove nozzle from the end of the nozzle
extension using a 2 mm or 5/64 allen wrench.
• Use the wire included in the kit or a small paper
clip to free the foreign materials clogging or
restricting the nozzle.
• 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.
O–Ring Maintenance
Your pressure washer uses o-rings to keep hose and
spray gun connections tight and leak-free. Through
the normal operation of your unit, these o-rings 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. Refer to the
instruction sheet provided in the kit to service your
unit’s o-rings. Note that not all of the parts in the kit
will be used on your unit.
Parts in the O–Ring Kit include:
• 1 o–ring, red, (p/n B2726) for the end of the spray
gun connection between gun and nozzle extension.
