Note: Engine power will decrease 3-1/2% for each 1,000 feet (300 meters) above sea level and
1% for each 10_ F (5.6_ C) above 77_F (25_ C). It will operate satisfactorily at an angle
up to 15_. Refer to the equipment operator manual for safe allowable operating limits
on slopes.

Technical Information

Engine Power Rating Information
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.

STORAGE
Engines stored over 30 days need to be protected or drained of fuel to prevent gum
from forming in fuel system or on essential carburetor parts.
For engine protection, we recommend use of Briggs & Stratton Fuel Stabilizer
available from an Authorized Briggs & Stratton Service Dealer. Mix stabilizer with fuel in
fuel tank or storage container. Run engine for a short time to circulate stabilizer through
carburetor. Engine and fuel can be stored up to 24 months.
Note: If stabilizer is not used or if engine is operating on gasoline containing alcohol,
e.g. gasohol, remove all fuel from tank and run engine until it stops from lack of fuel.
1. Change oil. See Oil service.
2. Remove spark plug and pour about 30 ml (1 oz) of engine oil into cylinder.
Replace spark plug and crank slowly to distribute oil.
3. Clean chaff and debris from cylinder and cylinder head fins, under finger guard
and behind muffler.
4. When removing the unit from storage, only use fresh gasoline. Perform
operation checks, see maintenance schedule, before starting engine.
