2. Slowly add oil into the engine oil fill (C, Figure 14). Do not put too much oil in the
engine oil fill. Wait one minute and then check the oil level.
NOTE: Do not add oil at the quick oil drain, if equipped.
3. Install and tighten the dipstick (A, Figure 14).
4. Remove the dipstick and check the oil level. The correct oil level is at the top of the
full indicator (B, Figure 14) on the dipstick.
5. Install and tighten the dipstick (A, Figure 14).
6. Connect the spark plug wire(s) to the spark plug(s). See Remove Oil section.
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 use either a foam or a paper filter. Some models can also have an
optional pre-cleaner that can be cleaned and used again. Compare the illustrations in
this manual with the type installed on your engine.
1. Open the fastener(s) (A, Figure 15) and remove the cover (B).
2. Remove the nut (C, Figure 15) and the retainer (D).
3. To make sure debris does not enter the carburetor, remove the foam element from
the air filter base.
4. Remove the air filter (E, Figure 15).
5. To loosen debris, lightly tap the filter on a hard surface. If the air filter is dirty,
replace it with a new filter.
6. Remove the pre-cleaner (F, Figure 15), if equipped, from the air filter (E).
7. Clean the pre-cleaner (F, Figure 15), if equipped, in liquid detergent and water. Let
the pre-cleaner fully air dry. DO NOT lubricate the pre-cleaner.
8. Install the dry pre-cleaner (F, Figure 15), if equipped, to the air filter (E).
9. Install the air filter (E, Figure 15) and attach with the retainer (D) and nut (C).
10. Install the cover (B, Figure 15) and attach with the fastener(s) (A).
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 installed
1. Before you clean or replace the fuel filter (A, Figure 16), 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 16) 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. Examine the fuel lines (D, Figure 16) for cracks or leaks. Replace if necessary.
4. Replace the fuel filter (A, Figure 16) with an original equipment replacement filter.
5. Attach the fuel lines (D, Figure 16) with clamps (C).
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 prevent 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 grille.
2. Keep linkage, springs, and controls clean.
3. Keep the area around and behind the muffler, if equipped, free of combustible
debris.
4. Make sure the oil cooler fins, if equipped, are clean.
After a period of time, the cylinder cooling fins can collect debris and cause the engine
to overheat. This unwanted material 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
Fuel System
Refer to Figure: 17.
WARNING
Fuel and its vapors are flammable and explosive. Fire or explosion could result in
burns or death.
Fuel Storage
• Because pilot lights or other ignition sources can cause explosions, keep fuel or
equipment away from furnaces, stoves, water heaters or other appliances that
have pilot lights.
Keep the engine level at the correct operating position. Fill the fuel tank (A, Figure 17)
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. The
use of an alcohol-free fuel stabilizer and ethanol treatment in the fuel storage container
is recommended. This keeps fuel fresh and decreases fuel-related problems or
contamination in the fuel system.
When you fill the container with fuel, add an alcohol-free fuel stabilizer as specified by
the manufacturer's instructions. 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 is
out of fuel.
NOTE: DO NOT run the Electronic Fuel Injection engine out of fuel. Fuel pump damage
can occur. Make sure to add the correct amount of fuel stabilizer to the fuel tank, and
run the engine for 30 minutes.
Engine Oil
While the engine is still warm, change the engine oil. Refer to Change the Engine Oil
section.
