inhaled or ingested, causing severe nausea,
fainting or poisoning. The harmful elements may
cause property damage or severe injury.
• 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. See “Storage” on
page 15 for cold weather protection.
• 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.
• Never operate units with broken or missing parts,
or without protective housing or covers.
• 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 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.

• 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 dealer.

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
2.4 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.
• 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.
• Rotate the fuel shut-off valve to the “On” position
(fully counter-clockwise).
• Move the throttle lever to “Fast” position.
• Move the choke lever to the “Choke” position.
NOTE: For a warm engine, be sure the choke lever is
in the “Run” position.
• Grasp the unit’s handle with your left hand. Pull the
starter grip 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 throttle lever to “Stop” position.
• Turn the fuel shut-off valve to the “Off” position
(fully clockwise).
• Squeeze trigger on the spray gun to relieve
pressure in the hose.

How To Use the Adjustable Nozzle
Now that you know how to START and STOP your
pressure washer, 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.
• Point the nozzle towards a hard surface, 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.
• 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
lowest 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.
• 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.
Slide nozzle backward for
high pressure mode.
Slide nozzle forward for
low pressure mode and
detergent application.
Twist nozzle counterclockwise for fan pattern.
Twist nozzle clockwise for
narrow spray pattern.
10
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 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.
How to Use the Hose Reel
Your pressure washer is equipped with a hose reel
that is designed to store your hose when unit is not in
use. These instructions are for short term storage
only. For long term storage see “Storage” on page 15.
After each use:
• Disconnect hose from spray gun and high pressure
outlet on pump.
• Drain water from hose.
• Slide one end of the hose into the hole on the hose
reel. Turn the hose reel with the handle to coil the
hose onto the reel.
• Push the other end of the hose into the clip on the
handle of your unit.
IMPORTANT: Do Not use your pressure washer with
the hose coiled onto the hose reel. The hose reel is for
storage purposes only.
Adjustable Hose Reel Spring Tension
The hose reel is provided with a spring tension
adjustment knob, as shown above.
Although the operator can loosen or tighten the knob
to achieve the desired reel tension, the manufacturer
recommends that the knob be fully hand tightened
(clockwise).

Nozzle Maintenance
A pulsing sensation felt while squeezing the spray gun
trigger may be caused by excessive pump pressure.
The principal cause of excessive pump pressure is a
nozzle clogged or restricted with foreign materials,
such as dirt, etc. To correct the problem, immediately
clean the nozzle using the tools included with your
pressure washer and follow these instructions:
1. Shut off the engine and turn off the water supply.
2. Detach the nozzle extension from the spray gun.
Twist the nozzle clockwise to the stream position.
Using the supplied 2mm (5/64) allen wrench,
remove the nozzle from the end of the nozzle
extension.
3. Remove the in-line filter from the other end of the
nozzle extension.
4. Use the wire included in the kit (or a small paper
clip) to free any foreign material clogging or
restricting the nozzle.

and start the engine.
9. Test the pressure washer by operating with nozzle
in the high and in the low 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 spray gun and nozzle
extension.
• 1 o–ring, yellow, (p/n B2264) for the end of the
high pressure hose.
NOTE: The above two o–rings are close in size.
Please match carefully to assure proper o–ring usage.
• 1 water inlet screen (p/n B2384) for the garden
hose connector.
To remove a worn or damaged O–Ring:
• Use a small flathead screwdriver to get underneath
the o–ring and pry it off.
ENGINE MAINTENANCE
Checking Oil Level
Oil level should be checked prior to each use or at
least every 5 hours of operation. Keep oil level
maintained.
Changing Oil
Change engine oil after the first 5 hours and every
50 hours thereafter. If you are using your pressure
washer under extremely dirty or dusty conditions, or in
extremely hot weather, change oil more often.
Change oil while engine is still warm from running, as
follows:
• Drain fuel tank by running pressure washer until
fuel tank is empty.
• Disconnect spark plug wire and keep it away from
the spark plug.
• Remove oil drain plug and drain oil into appropriate
receptacle.
• Reinstall drain plug. Remove oil fill cap.
• Fill to point of overflowing at oil fill cap with
recommended oil.
• Reinstall oil fill plug and tighten securely.
• Wipe up any remaining oil.
• Reconnect spark plug wire to the spark plug.
Insert wire into nozzle and turn back
and forth to clear obstruction.
