thin stream. Continue to hold trigger until there is a
steady stream of water and no air remains in the
system. Release the trigger.
Safety Latch
Engage the safety latch to the spray gun trigger.
• 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 knob to
the "Run" position. If engine falters, move choke
knob to the "Choke" position, then to the "Run"
position.
• If engine fails to start after six pulls, move choke
knob to the "Run" position. If engine fires, but does
not continue to run, move choke knob to the
"Choke" position, then to the "Run" position.

necessary to squeeze the gun trigger to relieve
internal pump pressure.
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.
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 an adjustable nozzle
that you can use to adjust the spray pattern and the
spray pressure.
• Slide the nozzle forward for low pressure spray;
slide it backward for high pressure spray.
• For most effective cleaning, keep the spray nozzle
between 8 to 24 inches away from cleaning
surface.

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 keep the
surface wet.
• 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 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.

nearest Sears service center. Engine performance
may be affected at attitudes above 7000 feet. For
operation at higher elevations, contact your nearest
Sears service center.
Spark Arrester Service
Your engine is not factory-equipped with a spark
arrester. In some areas, it is illegal to operate an
engine without a spark arrester. Check local laws and
regulations. A spark arrester is available from your
nearest Sears service center. If you need to order a
spark arrester, please call 1-800-366-PART.
The spark arrester must be serviced every 50 hours to
keep it functioning as designed.
If the engine has been running, the muffler will be very
hot. Allow the muffler to cool before servicing the
spark arrester.

AFTER EACH USE
Water should not remain in the unit for long periods of
time. Sediments or minerals can deposit on pump
parts and "freeze" pump action. Follow these
procedures after every use:
• 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.
• Shut off engine, let it cool, then remove all hoses.
• Disconnect spark plug wire from spark plug.
• Empty the pump of all liquids by pulling recoil
handle about 6 times. This should remove most of
the liquid in the pump.
• If storing for more than 30 days see "Long Term
Storage" on next page.
• Coil the high pressure hose and inspect it for
damage. Cuts in the hose or fraying could result in
leaks and loss of pressure. Should any damage be
found, replace the hose. Do Not attempt to repair a
damaged hose. Replace the hose with the genuine
Sears part.
• Disconnect hose from spray gun and high pressure
outlet on pump. Drain water from hose, gun, and
nozzle extension and use a rag to wipe off the
hose.
• Coil hose and properly hang it on the wire support
provided.
• Reconnect spark plug wire to spark plug.
• Store unit in a clean, dry area.
WINTER STORAGE
CAUTION! You must protect your unit from freezing
temperatures. Failure to do so will permanently
damage your pump and render your unit inoperable.
Freeze damage is not covered under warranty.
To protect the unit from freezing temperatures:
• 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.
• Empty the pump of all pumped liquids by pulling
recoil handle about 6 times. This should remove
most of the liquid in the pump.
• Use pump saver, available at Sears retail item
# 74403, to treat pump. This prevents freeze
damage and lubricates pistons and seals.
• If pump saver is not available, connect a 3-foot
section of garden hose to the water inlet adapter.
Pour RV-antifreeze (antifreeze without alcohol) into
the hose. Pull the recoil handle twice. Disconnect
3-foot hose.
_ WARNING! Never store the engine with fuel in
the gas tank indoors or in enclosed, poorly
ventilated areas where fumes may reach an
open flame, a spark, or pilot light.
