perform these tasks before you can operate your
pressure washer:
1. Add oil to engine crankcase.
2. Add fuel to fuel tank.
3. Connect high pressure hose to spray gun and pump.
4. Connect water supply to pump.
Add Engine Oil
IMPORTANT: Any attempt to crank or start the engine
before it has been properly serviced with the
recommended oil may result in an engine failure.
NOTE: When adding oil to the engine crankcase, use
only high quality detergent oil rated with API service
classification SF, SG, SH, SJ or higher. DO NOT use
special additives.
1. Choose a viscosity according to the following table.
STARTING TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
* 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 and
clean area around oil fill.
3. Remove dipstick and wipe clean with cloth.
4. Replace and tighten dipstick.Remove and check
oil level.
5. Slowly pour oil into oil fill opening. Pause to permit
oil to settle. Fill to "Full" mark on dipstick. DO NOT
OVERFILL. Remove dipstick and check oil level.

ENGINE TECHNBCAL INFORMATION
This is a single cylinder, Uhead, air cooled engine, it
is a low emissions engine.
in the State of California, Model Series 90000 engines
are certified by the California Air Resources Board to
meet emissions standards for 125 hours. Such
certification does not grant the purchaser, owner or
operator of this engine any additional warranties with
respect to the performance or operational life of this
engine. The engine is warranted solely according to
the product and emissions warranties stated
elsewhere in this manual.
Power Ratings
The power ratings for an individual engine model are
initially developed by starting with SAE (Society of
Automotive Engineers) code J1940 (Small Engine
Power & Torque Rating Procedure) (Revision 2002-
05). Given both the wide array of products on which
our engines are placed, and the variety of
environmental issues applicable to operating the
equipment, it may be that the engine you have
purchased will not develop the rated horsepower when
used in a piece of power equipment (actual "on-site"
power). This difference is due to a variety of factors
including, but not limited to, the following: differences
in altitude, temperature, barometric pressure, humidity,
fuel, engine lubrication, maximum governed engine
speed, individual engine to engine variability, design of
the particular piece of power equipment, the manner in
which the engine is operated, engine run-in to reduce
friction and clean out of combustion chambers,
adjustments to the valves and carburetor, and other
factors. The power ratings may also be adjusted
based on comparisons to other similar engines utilized
in similar applications, and will therefore not
necessarily match the values derived using the
foregoing codes.

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, contact your local Sears service center.
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 spark
arrester.
WARNING
DO NOT touch hot surfaces.
Allow equipment to coo! before touching.
The pressure washer must be at least 5 feet from
structures having combustible walls and/or other
combustible materials.
Keep at least 3 feet of clearance on al! sides of pressure
washer for adequate cooling, maintenance and servicing.
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. If you equip the muffler with a spark attester,
it must be maintained in effective working order.
Remove spark arrester screen for cleaning and
inspection.
Replace if screen is damaged.
Air Cooling System
Over time debris may accumulate in cylinder cooling
fins and cannot be observed without partial engine
disassembly. For this reason, we recommend you have
an authorized Sears service dealer clean the cooling
system per recommended intervals (see "Maintenance
Schedule" on page 13). Equally important is to keep top
of engine free from debris. See "Clean Debris".
Keep areas within heavy line clear of debris.
C_ean Combustion Chamber
We recommend you have an authorized Sears service
dealer remove combustion deposits from the cylinder,
cylinder head, top of piston and around valves per
recommended intervals (see "Maintenance Schedule"
on page 13).

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 detergent siphoning tube by placing the filter
into a pail of clean water while running pressure
washer in low pressure mode. Flush for one to two
minutes.
2. Shut off engine, let it cool, then remove all hoses.
3. Disconnect spark plug wire from spark plug.
4. Empty pump of all liquids by pulling recoil handle
about 6 times. This should remove most liquid in
pump.
5. if storing for more than 30 days see "Long Term
Storage" on next page.
6. Coil 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.
7. 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.
8. Reconnect spark plug wire to spark plug.
9. Store unit in a clean, dry area.
WARNING
WINTER STORAGE
CAUTtON
• Failure to do so will permanently damage your pump
and render your unit inoperable.
•Freeze damage is not covered under warranty.
To protect the unBtfrom freezing temperatures:
1. Flush detergent siphoning tube by placing filter
into a pail of clean water while running pressure
washer in low pressure mode. Flush for one to two
minutes.
2. Empty pump of all pumped liquids by pulling recoil
handle about 6 times. This should remove most
liquid in pump.
3. Use pump saver, available at a local Sears service
center, to treat pump. This minimizes freeze
damage and lubricates pistons and seals.
4. 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.
WHEN STORING FUEL OR EQUIPMENT WiTH FUEL IN
TANK
Store away from furnaces, stoves, water heaters, clothes
dryers or other appliances that have pilot light or other
ignition source because they can ignite fuel vapors.
WHEN DRAINING FUEL
Turn pressure washer OFF and let it cool at least 2
minutes before removing fuel cap. Loosen cap slowly to
relieve pressure in tank.
Drain fuel tank outdoors.
Keep fuel away from sparks, open flames, pilot lights,
heat, and other ignition sources.
DO NOT light a cigarette or smoke.
17

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 aicoholzblended 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 fue[ can
be stored up to 24 months with additive.
• Add fue[ 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 Oil"
on page 15.
Oil Cylinder Bore
• Remove spark plug. Squirt about 1/2 oz. of clean
engine oil into the cylinder. Cover spark plug hole
with rag. Pui[ recoil handle slowly to distribute oil.
Avoid spray from spark plug hole.
• Instal[ 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.
CAUTION
*Failure to do so will permanently damage your pump
and render your unit inoperable,
, Freeze damage is not covered under warranty.
NOTE: Sears pump saver is available as an optional
accessory. It is not included with the pressure washer.
CAUTION
Always wear eye protection when using PumpSaver.
To use the pump saver:
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.
