ENGINE TECHNICAL INFORMATION

This is a single cylinder, L-head, 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.

SERVICE DATES

GENERAL RECOMMENDATIONS

Regular maintenance will improve the performance

and extend the life of the pressure washer. See any

Sears or other qualified service dealer 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.

EMISSION CONTROL

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

BEFORE EACH USE

1. Check engine oil level.

2. Check water inlet screen for damage.

3. Check in-line filter for debris.

4. Check high pressure hose for leaks.

5. Check chemical filters for damage.

6. Check gun and nozzle extension assembly for

leaks.

7. Purge pump of air and contaminants.

CAUTION

• DO NOT insert any objects through cooling slots.

• Use a damp cloth to wipe exterior surfaces clean.

• Use a soft bristle brush to loosen caked on dirt, oil,
etc.

• Use a vacuum cleaner to pick up loose dirt and debris.

• Use low pressure air (not to exceed 25 psi) to blow
away dirt. Inspect cooling air slots and openings on
the pressure washer. These openings must be kept

clean and unobstructed.

Check and Clean Inlet Screen

Examine garden hose inlet screen. Clean if it is
clogged or replace if it is torn.

Check High Pressure Hose

High pressure hoses can develop leaks from wear,
kinking, or abuse. Inspect hose before each use.
Check for cuts, leaks, abrasions, bulging of cover, or
damage or movement of couplings. If any of these
conditions exist, replace hose immediately.

j A WARNING i

2. Place in-line filter screen into threaded end of
nozzle extension. Direction does not matter. Push

screen in with eraser end of pencil until it rests flat
at bottom of opening. Take care not to bend screen.

3. Place o-ring into recess. Push o-ring snugly against
in-line filter screen.

4. Assemble nozzle extension to spray gun, as
described earlier in manual.

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

spray tip clogged or restricted with foreign materials,
such as dirt, etc. To correct the problem, immediately

clean the spray tip following these instructions:

1. Shut off engine and turn off water supply.

2. Remove spray tip from end of nozzle extension.

3. Remove in-line filter from other end of nozzle
extension.

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

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

WARNING

WHEN ADJUSTING OR MAKING REPAIRS TO YOUR
PRESSURE WASHER

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

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

Oil

Oil Recommendations
NOTE: When adding oil to the engine crankcase, use

only high quality detergent oil classified "For Service SF,
SG, SH, SJ" or higher. DO NOT use special additives.

1. Choose a viscosity according to the following table:

104 F_

68
5O

32

14

4

-22

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.

SAE 30:40 °F and higher (5 °C and higher) is good

for all purpose use above 40°F, use below 40°F will

cause hard starting.
10W-30:0 to 100 °F (-18 to 38 °C) is better for

varying temperature conditions. This grade of oil
improves cold weather starting, but may increase oil
consumption at 80°F(27°C) or higher.
*Check oil level frequently at higher temperatures.

Synthetic 5W-30:-20 to 120 °F (-30 to 40 °C)
provides the best protection at all temperatures as well
as improved starting with less oil consumption.

5W-30:40 °F and below (5 °C and below) is
recommended for winter use, and works best in cold

conditions.
