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
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.
• Squeeze trigger on gun to purge pump system of
air and impurities.
• Attach nozzle extension to spray gun. Tighten by
hand.
Move the throttle lever to "Fast" position, shown
here as a rabbit.
• Move the choke lever to the "Choke" position.
NOTE: For a warm engine, be sure the choke lever is
in the "Run" position.
• Place your left foot on the lower frame and grasp
the handle as shown. Your unit may appear slightly
different from that shown here.
• Position the nozzle in the low pressure mode (slide
nozzle forward) and squeeze the trigger on the
spray gun to relieve 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. Release the trigger.
• Engage the safety latch to the spray gun trigger.
Safety Latch
• Pull the starter grip handle lightly with your right
hand until you feel some resistance, then pull
briskly.
• Return the starter grip handle slowly. DO NOT let
rope "snap back" against starter.
• When engine starts, slowly move choke lever to
the "Run" position. If engine falters, move choke
lever to the "Choke" position, then to the "Run"
position.
• If engine fails to start after six pulls, move choke
lever to the "Run" position. If engine fires, but does
not continue to run, move choke lever to the
"Choke" position, then to the "Run" position.
NOTE: If the recoil starter is hard to pull, it may be
necessary to squeeze the gun trigger to relieve
internal pump pressure.
How to Stop Your Pressure Washer
• Move the 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.
On the end of your spray gun is a nozzle handle that
can adjust the spray pressure and the spray pattern.
• Point the nozzle toward the ground, disengage the
safety latch, and press the trigger to test the
pattern.
Rotating the nozzle adjusts the spray pattern from
a narrow pattern to a fan pattern.
I ,
Twist nozzle counter- Twist nozzle clockwise for
clockwise for fan pattern, narrow spray 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.
Sliding the nozzle forward and back adjusts the
spray pressure.
Applying Detergent with 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 the detergent solution as required by the
job.
• Hang the detergent solution container on the hook
attached to the handle.
Slide nozzle backward for
high pressure mode.
Slide nozzle forward for low
pressure mode and
detergent application.
• 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.
• 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. 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 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.
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.
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 125°-155°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.

washer in low pressure mode (adjustable nozzle in
the forward position). Flush for one to two minutes.
• Shut off the engine and let it cool, then remove all
hoses.

handle about 6 times. This should remove most of
the liquid in the pump.
