HOW TO USE YOUR PRESSURE
WASHER
If you have any problems operating your pressure
washer, please call the pressure washer helpline at
1-800-222-3136.
To Start Your Pressure Washer
The best way to start your engine-powered pressure
washer for the first time is to 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" (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.
_ AUTION: 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 trigger on gun to purge pump system of
air and impurities.
• Attach nozzle extension to spray gun. Tighten by
hand.
• Choose the nozzle you want to use and insert it
into the nozzle extension. See "How to Use the
Nozzles".
• Engage the safety latch to the spray gun trigger.
Latch
Move throttle lever to "Fast" position, shown here
as a rabbit.
\
• Pull the starter grip handle lightly until you feel
some resistance, then pull briskly.
• Return the starter grip handle slowly. Do Not let
rope "snap back" against starter.
• If the engine fails to start, disengage safety latch
and squeeze trigger on gun to release pump
pressure. Engage safety latch and repeat previous
two steps.
• If the choke knob was placed in the "Choke"
position to start the engine, move it slowly to the
"Run" position as the engine warms up enough to
run smoothly.
How to Stop Your Pressure Washer
• Move throttle lever on engine 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.
• Move the choke knob to the "Choke" position.
NOTE: For a warm engine, be sure the choke knob is
in the "Run" position.
How to Use the Nozzles
_ DANGER! Never exchange nozzles without
locking the safety latch on the trigger.
The quick-connect on the nozzle extension allows you
to switch between four different nozzles. The nozzles
vary the spray pattern as shown below.

To change nozzles:
• Engage the safety latch on the spray gun.
• Pull back the collar on the quick-connect and pull
the current nozzle off. Store the nozzle in the
space provided on the control panel.
NOTE: For a more gentle rinse, select white 40 °
nozzle. To scour the surface, select yellow 15° or red
0° nozzle. To apply chemical, select black low
pressure nozzle.
• Pull back on the collar, insert the new nozzle and
release the collar. Pull on the nozzle to make sure
it is securely in place.
• For most effective cleaning, keep the spray nozzle
between 8 to 24 inches away from the cleaning
surface. If you get the spray nozzle too close, you
may damage the cleaning surface.
Cleaning and Applying Chemical
• Apply the detergent to a dry surface, starting at
lower portion of area to be washed and work
upward, using long, even, overlapping strokes. Do
Not allow the detergent to dry on. Allowing
detergent to dry on surface may cause streaking.
• Allow the detergent to soak between 3-5 minutes
before washing and rinsing. Reapply as needed to
prevent surface from drying.
Pressure Washer Rinsing
_ ARNING! 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 force you to fall. The
high pressure spray could also force you to fall if
you are too close to the cleaning surface.
_ ARNING! 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.
IMPORTANT: Use soaps designed specifically for
pressure washers. Household detergents could
damage the pump.
To apply detergent follow these steps:
• Review the use of the nozzles.
• Prepare the detergent solution as required by the
manufacturer.
• Hang the detergent solution container on the hook
at the rear of the pressure washer.
• Place the small filter of the chemical injection tube
into the detergent container.
_ AUTION! Keep the chemical injection tube
from coming in contact with the hot muffler. This
will damage the chemical injection tube. When
inserting the filter into a chemical bottle, route
the tube so as to keep it from inadvertently
contacting the hot muffler.
• Make sure the black nozzle is installed on the
nozzle extension.
NOTE: Detergent cannot be applied with the high
pressure nozzles (White, Yellow, or Red).
• Make sure the garden hose is connected to the
water inlet. Check that high pressure hose is
connected to spray gun and pump, then start
engine.
After you have applied detergent, scour the surface
and rinse it clean as follows:
• Apply safety latch to spray gun.
• Remove the black chemical nozzle from the nozzle
extension.
• Select and install the desired high pressure nozzle
following the instructions "How to Use the Nozzles"
on page 7.
• Keep the spray gun a safe distance from the area
you plan to spray.
• Apply a high pressure spray to an small area and
then check the surface for damage. If no damage
is found, you can assume it is okay to continue
cleaning.
• Start at the top of the area to be rinsed, working
down with same overlapping strokes used for
cleaning.
• The use of a brush may be helpful on some hard to
clean surfaces.
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. Once the pump has
cooled, it will stop discharging.
NOTE: This is not a leak. Do Not return the pressure
washer.
