STORAGE
Fuel can become stale when stored over 30 days. Stale fuel causes acid and
gum deposits to form in fuel system or on essential carburetor parts. Mix fuel
stabilizer with fuel in tank or storage container. Run engine for a short time to
circulate stabilizer through carburetor and engine. Engine and fuel can be stored
up to 24 months.
If fuel stabilizer is not used, you need to drain gasoline from equipment prior to
storage. Run engine until it stops from lack of fuel.
If FRESH START fuel cap with concentrated slow drip liquid cartridge is used,
there is no need to drain fuel, as long as cartridge contains stabilizer for seasonal
storage.
1. Change oil.
2. Remove spark plugs and pour about 30 ml (1 oz) of engine oil into
cylinders. Replace spark plugs and crank slowly to distribute oil.
3. Clean grass/chaff from cylinders and cylinder head fins and behind muffler.
4. When engine is cooled from operating, Store in a clean dry area.
WARNING
Do not store in same area as a stove, furnace, water heater, or other
appliance that uses a pilot light or has a device that can create a spark.
Engine fumes could ignite.

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.
