See Figure: 10, 11
WARNING
Running engines produce heat. Engine parts, especially muffler, become extremely
hot.
Severe thermal burns can occur on contact.
Combustible debris, such as leaves, grass, brush, etc., can catch fire.
• Allow muffler, engine cylinder and fins to cool before touching.
• Remove accumulated debris from muffler area and cylinder area.
NOTICE
Do not use water to clean the engine. Water could contaminate the fuel
system. Use a brush or dry cloth to clean the engine.
This is an air cooled engine. Dirt or debris can restrict air flow and cause the engine to
overheat, resulting in poor performance and reduced engine life.
1. Use a brush or dry cloth to remove debris from the air intake area (A, Figure 10).
2. Keep linkage, springs and controls (B, Figure 11) clean.
3. Keep the area around and behind the muffler (C, Figure 11) free of any combustible
debris.
4. Make sure the oil cooler fins (D, Figure 11) are free of dirt and debris.
5. Loosen fastener(s) (E, Figure 10) until you hear a click. Remove panel (F). and clean
the area of dirt and debris. Make sure the underside of the panel is also clean.
6. Install the panel (F, Figure 10) and secure with fastener(s) (E). Tighten fastener(s)
until you hear a click.
7. Cyclonic Air Filter System (G, Figure 10): Loosen fastener (H, Figure 10) 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
Gaseous 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.
Engine Oil
While the engine is still warm, change the engine oil. See the Change Engine Oil section.
NOTICE Store the engine level (normal operating position). If the engine is tipped in
any other direction, it may be difficult to start due to oil contaminating the air filter and/or
the spark plug.

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.
