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.

GENERAL RECOMMENDATIONS
Regular maintenance will improve the performance
and extend the life of the pressure washer. See any
authorized Sears 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.
