ENGINE TECHNICAL iNFORMATiON

This is a single cylinder, Uhead, air cooled engine, it
is a low emissions engine.

in the State of California, Model Series
100000 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.

Regular maintenance wilJ improve the performance
and extend the life of the pressure washer. See any

authorized Sears deaJer for service.

The pressure washer warranty does not cover items
that have been subjected to operator abuse or

negligence. To receive full value from the warranty,

the operator must maintain pressure washer as

instructed in this manual including proper storage as

detailed in "Storage" on pages 18-19.

Some adjustments will need to be made periodically to
properly maintain your pressure washer.

All service and adjustments should be made at least
once each season. Follow the requirements in the

"Maintenance Schedule" chart above.

NOTE: Once a year you should clean or replace the

spark plug and replace the air filter. A new spark plug
and clean air filter assure proper fuel-air mixture and

help your engine run better and last longer.
If equipped with inflatable tires, keep the air pressure

at the value marked on the tire or within 15 and 40 psi.

Maintenance, replacement or repair of the emission
control devices and systems may be performed by any
non-road engine repair establishment or individual.

extension.

.

Use a small paper clip to free any foreign material
clogging or restricting spray tip.

• NEVER repair high pressure hose, Replace it,

• Replacement hose rating MUST exceed maximum
pressure rating of unit.

Check Gun and Nozzle Extension

Examine hose connection to gun and make sure it is
secure. Test trigger by pressing it and making sure it
springs back into place when you release it. Engage
trigger lock and test trigger. You should not be able to
press trigger. Replace gun immediately if it fails any of

these tests.

ENGINE MAINTENANCE

Oil Recommendations
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

NOTE: Synthetic oil meeting ILSAC GF-2, API
certification mark and API service symbol with "SJ/CF
ENERGY CONSERVING" or higher, is an acceptable

oil at all temperatures. Use of synthetic oil does not
alter required oil change intervals.

* 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.

Checking Oil Level
Oil level should be checked prior to each use or at least

every 5 hours of operation. Keep oil level maintained.

1. Make sure pressure washer is on a level surface.

2. Remove oil dipstick and wipe dipstick with clean
cloth. Replace and tighten dipstick. Remove and

and check oil level.

3. Verify oil is at "Fulr' mark on dipstick. Replace and
tighten dipstick.

WHEN ADJUSTING OR MAKING REPAIRS 3"O YOUR
PRESSURE WASHER

Disconnect the spark plug wire from the spark plug and
place the wire where it cannot contact spark plug.

WHEN TESTING FOR ENGINE SPARK

Use approved spark plug tester.
DO NOT check for spark with spark plug removed,

/

Adding Engine Oil

1. Make sure pressure washer is on a level surface.

2. Check oil level as described in "Checking Oil Level".

3. If needed, slowly pour oil into oil fill opening to the
"Full" mark on dipstick. DO NOT overfill.
