* The use of multi-viscosity oils (5W-30, 10W-30, etc.)
in temperatures above 40=F (4=C) will result in higher
than normal oil consumption. When using a multi-
viscosity oil, check oil more frequently.
** If using SAE 30 oil in temperatures below 40=F
(4:C), it will result in hard starting and possible
engine bore damage due to inadequate lubrication.
2. Place pressure washer on a level surface.
3. Clean area around oil fill.
4. Remove oil fill cap and dipstick.
4. Install fuel cap and wipe up any spilled fuel.
IMPORTANT: It is important to prevent gum deposits
from forming in essential fuel system parts, such as the
carburetor, fuel filter, fuel hose or tank during storage.
Also, experience indicates that alcohol-blended fuels
(called gasohol, ethanol or methanol) can attract
moisture, which leads to separation and formation of
acids during storage. Acidic gas can damage the fuel
system of an engine while in storage.
To avoid engine problems, the fuel system should be
emptied before storage of 30 days or longer. See
"Storage" on pages 16-17. NEVER use engine or
carburetor cleaner products in the fuel tank or
permanent damage may occur.

may be affected at altitudes above 3000 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. Ifyou 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.

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:
1. Flush chemical system by turning its chemical
shut-off valves to "Off' position and run pressure
washer with black spray tip. Flush for one to two
minutes.
2.
3.
4.
.
6.
7.
.
Shut off engine, let it cool, then remove all hoses.
Disconnect spark plug wire from spark plug.
Empty pump of all liquids by pulling recoil handle
about 6 times. This should remove most liquid in
pump.
If storing for more than 30 days see "Long Term
Storage" on next page.
Uncoil high pressure hose and inspect it for
damage. Cuts in hose or fraying could result in
leaks and loss of pressure. Should any damage
be found, replace hose. DO NOT attempt to repair
a damaged hose. Replace hose with genuine
Sears part.
Disconnect hose from spray gun and high
pressure outlet on pump. Drain water from hose,
gun, and nozzle extension. Use a rag to wipe off
hose.
Slide one end of hose into hole on hose reel. Turn
hose reel with handle to coil hose onto reel.
9. Reconnect spark plug wire to spark plug.
10. Store unit in a clean, dry area.
,_ WARNINGI 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.
WINTER STORAGE
To protect the unit from freezing temperatures:
1. Empty all chemical reservoirs as follows:
a. Disconnect hose connected to chemical inject
fitting on pump. Place end of hose into
suitable container.
b. Rotate one of the chemical shut-off valves to
"On" position and open that tanks cover.
Gravity will empty tank contents into container.
c. When first tank is empty, repeat step (b) for
other tank, using a different container.
d. Reconnect hose to chemical inject fitting on
pump. Add 0.5 quart of clean fresh water to
each tank and close tanks covers.
2. Flush chemical system by selecting one tank,
turning its chemical shut-off valve to "On _ position
and run pressure washer with black spray tip.
Flush until first tank is empty. Turn its chemical
shut-off valve to "Off' position. Flush other tank
the same way.
3. Shut off engine and let it cool, then remove high
pressure and garden hoses. Disconnect spark
plug wire from spark plug.
4. Empty pump of all pumped liquids by pulling recoil
handle about 6 times. This should remove most
liquid in pump.
5. Use pump saver, available at Sears retail item
71-74403, to treat pump. This minimizes freeze
damage and lubricates pistons and seals.
6. If pump saver is not available, connect a 3-foot
section of garden hose to water inlet adapter. Pour
RV-antifreeze (antifreeze without alcohol) into
hose. Pull recoil handle twice. Disconnect 3-foot
hose.

LONG TERM STORAGE
If you do not plan to use the pressure washer for more
than 30 days, you must prepare the engine and pump
for long term storage.
It is important to prevent gum deposits from forming in
essential fuel system parts such as the carburetor, fuel
filter, fuel hose or tank during storage. Also,
experience indicates that alcohol-blended fuels (called
gasohol, ethanol or methanol) can attract moisture,
which leads to separation and formation of acids
during storage. Acidic gas can damage the fuel
system of an engine while in storage.
Protect Fuel System
Fuel Additive:
If adding a fuel additive, fill the fuel tank with fresh
fuel. If only partially filled, air in the tank will promote
fuel deterioration during storage. Engine and fuel can
be stored up to 24 months with additive.
Add fuel additive following manufacturer's
instructions.
Make sure you have water supply to pump inlet
connected and turned ON.
Run the engine outdoors for 10 minutes to be sure
that treated fuel has replaced the untreated fuel in
the carburetor.
If fuel additive is not used, remove all fuel from tank
and run engine until it stops from lack of fuel.
Change Oil
While engine is still warm, drain oil from crankcase.
Refill with recommended grade. See "Changing OiF on
page 14.
Oil Cylinder Bore
Remove spark plug. Squirt about 1 tablespoon of
clean engine oil into the cylinder. Cover spark plug
hole with rag. Pull recoil handle slowly to distribute
oil. Avoid spray from spark plug hole.
Install spark plug. DO NOT connect spark plug
wire.
Protect Pump
To protect the pump use Sears pump saver to prevent
freeze damage and lubricate pistons and seals.
Freeze damage is not covered underwarranty.
NOTE: Sears pump saver, item number 71-74403, is
available as an optional accessory. It is not included with
the pressure washer.
To use the pump saver:
CAUTION
1. Attach hose on pump saver can to pump inlet.
2. Push in can top to dispense pump saver.
3. When pump saver fluid begins to exit pump outlet,
the pump is protected.
4. Remove pump saver from pump inlet.
OTHER
DO NOT store fuel from one season to another.
If possible, store your unit indoors and cover it to
give protection from dust and dirt. BE SURE TO
EMPTY THE FUEL TANK.
IMPORTANT: NEVER cover your cleaning system
while engine and exhaust area are warm.
