6. Install the panel (F, Figure 14) and secure with fastener(s) (E). Tighten fastener(s)
until you hear a click.
7. Cyclonic Air Filter System (G, Figure 14): Loosen fastener (H, Figure 14) and
pivot Cyclonic Air Filter, if equipped, away from the engine. It is not necessary to
remove the flexible air cleaner hose (J). After cleaning, make sure to reposition the
air filter and tighten the fastener.
After a period of time, debris can accumulate in the cylinder cooling fins and cause the
engine to overheat. This debris cannot be removed without partial disassembly of the
engine. Have a Briggs & Stratton Authorized Dealer inspect and clean the air cooling
system as recommended in the Maintenance Schedule.
Storage
WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
When Storing Fuel Or Equipment With Fuel In Tank
• Store away from furnaces, stoves, water heaters or other appliances that have
pilot lights or other ignition sources because they can ignite fuel vapors.
Fuel System
See Figure: 16
Store the engine level (normal operating position). Fill fuel tank (A, Figure 16) with fuel.
To allow for expansion of fuel, do not overfill above the fuel tank neck (B).
Fuel can become stale when kept in a storage container for more than 30 days. Each
time you fill the container with fuel, add STA-BIL 360°
specified by the manufacturer's instructions. This keeps fuel fresh and decreases fuel-
related problems or contamination in the fuel system.
It is not necessary to drain fuel from the engine when STA-BIL
®
360° PROTECTION™ is added as instructed. Before storage, turn the engine ON for 2
minutes to move the fuel and stabilizer through the fuel system.
If gasoline in the engine has not been treated with a fuel stabilizer, it must be drained
into an approved container. Run the engine until it stops from lack of fuel. The use of a
fuel stabilizer in the storage container is recommended to maintain freshness.
Engine Oil
While the engine is still warm, change the engine oil. See the Change Engine Oil
section.

Engine power will decrease 3.5% for each 1,000 feet (300 meters) above sea level and
1% for each 10° F (5.6° C) above 77° F (25° C). The engine will operate satisfactorily
at an angle up to 15°. Refer to the equipment operator's manual for safe allowable
operating limits on slopes.

We recommend that you see any Briggs & Stratton Authorized Dealer for all
maintenance and service of the engine and engine parts.
Power Ratings: The gross power rating for individual gasoline engine models is
labeled in accordance with SAE (Society of Automotive Engineers) code J1940 Small
Engine Power & Torque Rating Procedure, and is rated in accordance with SAE J1995.
Torque values are derived at 2600 RPM for those engines with "rpm" called out on the
label and 3060 RPM for all others; horsepower values are derived at 3600 RPM. The
gross power curves can be viewed at www.BRIGGSandSTRATTON.COM. Net power
values are taken with exhaust and air cleaner installed whereas gross power values
are collected without these attachments. Actual gross engine power will be higher than
net engine power and is affected by, among other things, ambient operating conditions
and engine-to-engine variability. Given the wide array of products on which engines
are placed, the gasoline engine may not develop the rated gross power when used in a
given piece of power equipment. This difference is due to a variety of factors including,
but not limited to, the variety of engine components (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 engine.
