6. Connect the spark plug wire(s) (D, Figure 9) to the spark plug(s) (E).
Servicing the Air Filter
WARNING
Fuel vapors are flammable and explosive. Fire or explosion could result in burns
or death.
• Do not start and operate 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 could result in
damage to the filter and solvents will dissolve the filter.
See the Maintenance Schedule for service requirements.
Different models will use a foam or a paper filter. Some models could also have an
optional pre-cleaner that can be washed and used again. Compare the illustrations in
this manual with the type installed on your engine and service as follows.
Cyclonic Air Filter
1. Open the fastener(s) (A, Figure 13) and remove the cover (B).
2. Remove the air filter (C, Figure 13).
3. To loosen debris, lightly tap the air filter on a hard surface. If the air filter is dirty,
replace it with a new air filter.
4. To remove the safety filter (D, Figure 13), if equipped, carefully pull it away from the
air cleaner body (E). Make sure that dirt or debris does not go into the engine.
5. Install the new safety filter (D, Figure 13) in the air cleaner body (E).
6. Install the air filter (C, Figure 13) above the safety filter (D).
7. Install the cover (B, Figure 13) and close the fastener(s) (A).
Low Profile Air Filter
1. Remove the fastener(s) (A, Figure 14).
2. Remove the cover (B, Figure 14).
3. Remove the fastener(s) (C, Figure 14) and retainer (D).
4. Remove the air filter (E, Figure 14).
5. Remove the pre-cleaner (F, Figure 14), if equipped, from the air filter (E).
6. To loosen debris, lightly tap the air filter (E, Figure 14) on a hard surface. If the air
filter is dirty, replace with a new air filter.
7. Clean the pre-cleaner (F, Figure 14), if equipped, in liquid detergent and water.
Make sure the pre-cleaner is fully dry. Do not lubricate the pre-cleaner.
8. Assemble the dry pre-cleaner (F, Figure 14), if equipped, to the air filter (E).
9. Install the air filter (E, Figure 14) with the retainer (D) and fastener(s) (C).
10. Install the cover (B, Figure 14) with the fastener(s) (A). Make sure the fastener(s) is
tight.
Servicing the Cooling System
WARNING
During operation, the engine and muffler become hot. If you touch a hot engine,
thermal burns can occur.
Combustible debris, such as leaves, grass, and brush can catch fire.
• Before you touch the engine or muffler, stop the engine and wait two (2)
minutes. Make sure that the engine and muffler are safe to touch.
• Remove debris from the muffler and engine.
NOTICE
Do not use water to clean the engine. Water could cause contamination of the fuel
system. Use a brush or dry cloth to clean the engine.
This is an air cooled engine. Dirt or debris can stop the air flow and cause the engine to
become too hot and result in unsatisfactory performance and decreased engine life.
1. Use a brush or dry cloth to remove debris from the air intake area (A, Figure 15).
2. Keep linkage, springs, and controls (B, Figures 15, 16) clean.
3. Keep the area around and behind the muffler (C, Figures 15, 16) free of
combustible debris.
4. Make sure the oil cooler fins (D, Figure 15) are free of dirt and debris.
5. Loosen the fastener(s) (E, Figures 15, 16) and remove the debris access panels
(F). Remove grass and debris that has collected on the cylinders.
6. Install the debris access panels (F, Figures 15, 16) and attach with fastener(s) (E).
After a period of time, debris can collect in the cylinder cooling fins and cause the engine
to overheat. This debris cannot be removed without partial disassembly of the engine.
As recommended in the Maintenance Schedule, have a Briggs & Stratton Authorized
Service Dealer inspect and clean the air cooling system.
Servicing the Fuel System
WARNING
Fuel and its vapors are flammable and explosive. Fire or explosion could result in
burns or death.
• Keep fuel away from sparks, open flames, pilot lights, heat, and other ignition
sources.
• Frequently examine the fuel lines, fuel tank, fuel cap, and connections for cracks
or leaks. Replace damaged parts.
• Before you clean or replace the fuel filter, drain the fuel tank or close the fuel
shut-off valve.
• If fuel spills, wait until it dries before you start the engine.
• Replacement parts must be of the same design and installed in the same
position as the original parts. Other parts could result in damage or an injury.
Fuel Filter, if equipped
1. Before you clean or replace the fuel filter (A, Figure 17), drain the fuel tank or close
the fuel shut-off valve. If the fuel tank is not drained, fuel leakage could occur and
cause a fire or explosion.
2. Use pliers to squeeze tabs (B, Figure 17) on the clamps (C), then move the clamps
away from the fuel filter (A). Twist and pull the fuel lines (D) off of the fuel filter.
3. Check the fuel lines (D, Figure 17) for cracks or leaks. Replace if necessary.
4. Replace the fuel filter (A, Figure 17) with an original equipment replacement filter.
5. Attach the fuel lines (D, Figure 17) with clamps (C).
Storage
Fuel System
Refer to Figure: 18.
Keep the engine level (normal operating position). Fill the fuel tank (A, Figure 18) with
fuel. For fuel expansion, do not fill 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. Operate the engine until it stops from lack of fuel. The use of
a fuel stabilizer in the storage container is recommended to keep fuel fresh.
Engine Oil
While the engine is still warm, change the engine oil. Refer to Change the Engine Oil
section.
