Service Air Filter
See Figure: 12, 13, 14
WARNING
Fuel and its 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.
Loosen the fastener(s) (A, Figure 12) that hold the cover (B).
2.
Remove the cover (B, Figure 12) and the filter (D).
3.
To loosen debris, gently tap the filter (D, Figure 12) on a hard surface. If the filter is
excessively dirty, replace with a new filter.
4.
Install the filter (D, Figure 12).
5.
Install the cover (B, Figure 12) and secure with fastener(s) (A). Make sure the
fastener(s) are tight.
Paper Air Filter
1.
Loosen the fastener(s) (A, Figure 13) and remove the cover (B).
2.
Remove the fastener(s) (C, Figure 13) and the filter (D).
3.
Remove the pre-cleaner (E, Figure 13), if equipped, from the filter (D).
4.
To loosen debris, gently tap the filter (D, Figure 13) on a hard surface. If the filter is
excessively dirty, replace with a new filter.
5.
Wash the pre-cleaner (E, Figure 13) in liquid detergent and water. Allow the pre-
cleaner to throughly air dry. Do not oil the pre-cleaner.
6.
Assemble the dry pre-cleaner (E, Figure 13) to the filter (D).
7.
Install the seal washer (F, Figure 13), the filter (D), and the pre-cleaner (E) into the
air filter base (G) and onto stud (H). Make sure the filter is properly assembled into
base and secure with the fastener(s) (C).
8.
Install the cover (B, Figure 13) and secure with fastener(s) (A). Make sure the
fastener(s) is tight.
Foam Air Filter
1.
Loosen the fastener(s) (A, Figure 14) that holds the cover (B).
2.
Open the cover (B, Figure 14) and remove the filter (C).
3.
Wash the foam element (C, Figure 14) in liquid detergent and water. Squeeze dry
the foam element in a clean cloth.
4.
Saturate the foam element (C, Figure 14) with clean engine oil. To remove excess
engine oil, squeeze the foam element in a clean cloth.
5.
Install the filter (C, Figure 14).
6.
Install the cover (B, Figure 14) and secure with the fastener(s) (A).
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
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.
