• DO NOT modify engine to run on alternate fuels.

To protect the fuel system from gum formation, mix in a fuel
stabilizer when adding fuel. See Storage. All fuel is not the
same. If you experience starting or performance problems
after using fuel, switch to a different fuel provider or change
brands. This engine is certified to operate on gasoline. The
emission control system for this engine is EM (Engine
Modifications).

CAUTION! 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 treated
with a fuel preserver or emptied before storage of 30 days or
longer. If adding a fuel preserver, fill the fuel tank with fresh
fuel. If only partially filled, air in the tank will promote fuel
deterioration during storage. If fuel preserver is not used,
drain the fuel tank, start the engine and let it run until the fuel
lines and carburetor are empty. Use fresh fuel next season. See
Storage for additional information.

NEVER use engine or carburetor cleaner products in the fuel
tank as permanent damage may occur.

High Altitude

At altitudes over 5,000 feet (1524 meters), a minimum
85 octane / 85 AKI (89 RON) gasoline is acceptable. To
remain emissions compliant, high altitude adjustment is
required. Operation without this adjustment will cause
decreased performance, increased fuel consumption, and
increased emissions. See a qualified Sears dealer for high
altitude adjustment information. Operation of the engine at
altitudes below 2,500 feet (762 meters) with the high altitude
kit is not recommended.

FreshStart® Fuel Cap

The FreshStart® fuel cap (A) is designed to hold a
cartridge (B) which contains fuel preserver. Adding fuel
preserver helps keep fuel fresh and carburetors clean for
easier starting all season long. The FreshStart® fuel cap, if
equipped with a cartridge, automatically drips concentrated
fuel preserver into your fuel tank so you don’t have to add it
yourself.

NOTE: FreshStart® fuel preserver cartridge is available as an
optional accessory, retail item 7133386. It is not included
with the pressure washer. Contact the original equipment
manufacturer, retailer, or dealer to obtain a cartridge
designed for the FreshStart® fuel cap installed on this
engine.

Read and follow all instructions and warnings given in the
FreshStart® fuel preserver cartridge package.

Connect Hose and Water Supply to Pump

NOTICE: DO NOT run the pump without the water supply
connected and turned on.

ENGINE TECHNICAL INFORMATION

This is a single cylinder, overhead valve (OHV), air cooled
engine. It is a low emissions engine.

In the State of California, Model 120000 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 gross power rating for individual gas engine models is
labeled in accordance with SAE (Society of Automotive
Engineers) code J1940 (Small Engine Power & Torque
Rating Procedure), and rating performance has been
obtained and corrected in accordance with SAE J1995
(Revision 2002-05). Torque values are derived at 3060 RPM;
horsepower values are derived at 3600 RPM. Actual gross
engine power will be lower and is affected by, among other
things, ambient operating conditions and engine-to-engine
variability. Given both the wide array of products on which
engines are placed and the variety of environmental issues
applicable to operating the equipment, the gas engine will not
develop the rated gross power when used in a given piece of
power equipment (actual "on-site" or net power). This
difference is due to a variety of factors including, but not
limited to, accessories (air cleaner, exhaust, charging,
cooling, carburetor, fuel pump, etc.), application limitations,
ambient operating conditions (temperature, humidity,
altitude), and engine-to-engine variability. Due to
manufacturing and capacity limitations, Briggs & Stratton
may substitute an engine of higher rated power for this
Series engine.

This pressure washer is rated in accordance to the Pressure
Washer Manufacturer’s Association (PWMA) standard
PW101 (Testing and Rating Performance of Pressure
Washers).
