Service Air Filter

See Figure: 8
WARNING
Gaseous vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
• Never start and run the engine with the air cleaner assembly (if equipped) or the
air filter (if equipped) removed.
NOTICE Do not use pressurized air or solvents to clean the filter. Pressurized air
can damage the filter and solvents will dissolve the filter.
See the Maintenance Schedule for service requirements.
Various models use either a foam or a paper filter. Some models may also have an
optional pre-cleaner that can be washed and reused. Compare the illustrations in this
manual with the type installed on your engine and service as follows.
Paper Air Filter
1. Remove the fastener(s) (A, Figure 8).
2. Remove the cover (B, Figure 8).
3. Remove the fastener(s) (C, Figure 8) and retainer (D).
4. Remove the air filter (E, Figure 8).
5. Remove the pre-cleaner (F, Figure 8), if equipped, from the air filter (E).
6. To loosen debris, gently tap the air filter (E, Figure 8) on a hard surface. If the air
filter is excessively dirty, replace with a new air filter.
7. Wash the pre-cleaner (F, Figure 8), if equipped, in liquid detergent and water.
Allow the pre-cleaner to thoroughly air dry. Do not oil the pre-cleaner.
8. Assemble the dry pre-cleaner (F, Figure 8), if equipped, to the air filter (E).
9. Install the air filter (E, Figure 8) and secure with retainer (D) and fastener(s) (C).
10. Install the cover (B, Figure 8) and secure with the fastener(s) (A). Make sure the
fastener(s) is tight.
Service Cooling System
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 grille.
2. Keep linkage, springs and controls clean.
3. Keep the area around and behind the muffler, if equipped, free of any combustible
debris.
4. Make sure the oil cooler fins, if equipped, are free of dirt and debris.
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 Service 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.
