Before Storage
Before you store your unit for the off-season, read the
Maintenance and Storage instructions in the Safety
Rules section, then perform the following steps:
• Turn the mower blades OFF, set the ground speed
control levers to START / PARK, set the parking brake
lever to ENGAGE, and remove the key from the igni-
tion switch.
• Check all fluid levels. Check all maintenance items.
Battery life will be increased if it is removed, put in a
cool, dry place and fully charged about once a
month. If the battery is left in the unit, disconnect the
negative cable.
It is important to prevent gum deposits from forming in
the essential fuel system parts such as the carburetor,
fuel filter, fuel line, and fuel tank during storage. Also,
alcohol blended fuels (called gasohol or using ethanol or
methanol) can attract moisture which leads to the sepa-
WARNING
Never store the unit (with fuel) in an enclosed,
poorly ventilated structure. Fuel vapors can travel
to an ignition source (such as a furnace, water
heater, etc.) and cause an explosion.
Fuel vapor is also toxic to humans and animals.
ration and formation of acids during storage. Acidic gas
can damage the fuel system of an engine while in stor-
age.
To avoid engine problems use fuel stabilizer, especially
before storage of 30 days or longer.
After Storage
Before starting the unit after it has been stored:
• Check all fluid levels. Check all maintenance items.
• Fill with FRESH fuel.
• After starting, allow the engine to warm before oper-
ating.

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 horsepower). 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.
