SAFETY RULES
3
• Do Not allow CHILDREN to operate the pressure
washer at any time.
• Operate engine only at governed speed. Running
the engine at excessive speeds increases the
hazard of personal injury. Do Not tamper with parts
which may increase or decrease the governed
speed.
• Do Not wear loose clothing, jewelry or anything
that may be caught in the starter or other rotating
parts.
• Before starting the pressure washer in cold
weather, check all parts of the equipment and be
sure ice has not formed there.
• Never use a spray gun which does not have a
trigger lock or trigger guard in place and in working
order.
• Keep the hose connected to machine or the spray
gun while the system is pressurized. Disconnecting
the hose while the unit is pressurized is dangerous.
• Units with broken or missing parts, or without
protective housing or covers, should NEVER be
operated.
• Check the fuel system for leaks or signs of
deterioration, such as chafed or spongy hose,
loose or missing clamps, or damaged tank or cap.
Correct all defects before operating the pressure
washer.
• Do Not spray flammable liquids.
• Use a respirator or mask whenever there is a
chance that vapors may be inhaled. Read all
instructions with mask so you are certain the mask
will provide the necessary protection against
inhaling harmful vapors.
• Never aim the spray gun at people, animals or
plants. The high pressure stream of water that this
equipment produces can pierce skin and its
underlying tissues, leading to serious injury and
possible amputation.
• Never allow any part of the body to come in
contact with the fluid stream. Do Not come in
contact with a fluid stream created by a leak in the
high pressure hose.
• Always wear eye protection when you use this
equipment or when you are in the vicinity where
the equipment is in use.
• High pressure spray can cause paint chips or other
particles to become airborne.
• Do Not operate the pressure washer above the
rated pressure.
• Never move the machine by pulling on the high
pressure hose. Use the handle provided on the
unit.
• Always be certain the spray gun, nozzles and
accessories are correctly attached.
• Do Not secure the spray gun in the (open)
position.
• High pressure spray may damage fragile items
including glass. Do Not point spray gun at glass
when in the jet spray mode.
• Hold the spray gun firmly in your hand before you
start the unit. Failure to do so could result in an
injury from a whipping spray gun. Do Not leave the
spray gun unattended while the machine is
running.
• The cleaning area should have adequate slopes
and drainage to reduce the possibility of a fall due
to slippery surfaces.
• Keep water spray away from electric wiring or fatal
electric shock may result.

machine.
• The muffler and engine heat up during operation
and remain hot immediately after shutting it down.
Avoid contact with a hot muffler or engine as you
could be severely burned.
• Operate and store this unit on a stable surface.
• High pressure hose can develop leaks from wear,
kinking, abuse, etc. Water spraying from a leak is
capable of injecting material into skin. Inspect hose
each time before using it. Check all hoses for cuts,
leaks, abrasions or bulging of cover, or damage or
movement of couplings. If any of these conditions
exist, replace hose immediately. Never repair high
pressure hose. Replace it with another hose that
exceeds maximum pressure rating of your unit.
• The muffler and air cleaner must be installed and in
good condition before operating the pressure
washer. These components act as spark arresters
if the engine backfires.
In the State of California a spark arrester is required
by law (Section 4442 of the California Public
Resources Code). Other states may have similar laws.
Federal laws apply on federal lands.
NOTE: If you equip the muffler with a spark arrester, it
must be maintained in effective working order. You
can order a spark arrester through your authorized
Sears service center.

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.
• Rotate the choke knob to the “Choke” position.
NOTE: For a warm engine, be sure the choke knob is
in the “Run” position.
• Move the throttle lever to “Fast” position, shown on
unit as a rabbit.
• As shown at the right, ensure the nozzle extension
is NOT attached to the spray gun.
• Place your left foot on the unit’s lower frame.
• Grasp the spray gun with your left hand and
squeeze the trigger on the spray gun. Water will
flow out of the spray gun in a thin stream. Continue
to squeeze the trigger. Your left hand will also
serve to steady the unit.
• Grasp the recoil starter handle with your right hand,
as shown. Pull the starter handle lightly until you
feel some resistance, then pull briskly. Return the
starter grip handle slowly. Do Not let rope “snap
back” against starter.

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
WARNING! 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.
CAUTION! 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.
• 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
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.
After you have applied detergent, scour the surface
and rinse it clean as follows:
• Apply safety latch to spray gun.

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 to the store.

Service Air Cleaner
Your engine will not run properly and may be
damaged if you run it with a dirty air cleaner.
Service the air cleaner once every 100 hours of
operation or once each year, whichever comes first.
Service more often if operating under dirty or dusty
conditions. Replacements are available at your local
Sears service center.
To service the air cleaner, follow these steps:
• Remove screws and lift cover.
• Carefully remove pre-cleaner and cartridge
assembly.
• After servicing pre-cleaner and cartridge, assemble
pre-cleaner on cartridge.
• Install pre-cleaner/cartridge in base.

Carburetor
If you think your carburetor needs adjusting, see your
nearest Sears service center. Engine performance
may be affected at altitudes above 4000 feet. For

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

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.
• Remove spark arrester screen for cleaning and
inspection.
• Replace if screen is damaged.
