Add Oil
• Make sure the engine is level.
• Clean the oil fill area of any debris.
• See the Specifications section for oil capacity.
1.
Remove the dipstick (A, Figure 8) and wipe with a clean cloth.
2.
Slowly pour oil into the engine oil fill (C, Figure 8). Do not overfill. After adding oil,
wait one minute and then check the oil level.
Note: Do not add oil at the quick oil drain (H, Figure 10), if equipped.
3.
Install and tighten the dipstick (A, Figure 8).
4.
Remove the dipstick and check the oil level. Correct oil level is at the top of the full
indicator (B, Figure 8) on the dipstick.
5.
Reinstall and tighten the dipstick (A, Figure 8).
6.
Connect the spark plug wire (D, Figure 8) to the spark plug (E).
Service Air Filter
See Figure: 12
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.
1.
Loosen the fastener(s) (A, Figure 12).
2.
Remove the cover (B, Figure 12).
3.
To remove the filter (C, Figure 12), lift the end of the filter and then pull the filter off
the intake (E).
4.
To loosen debris, gently tap the filter (C, Filter 12) on a hard surface. If the filter is
excessively dirty, replace with a new filter.
5.
Remove the pre-cleaner (D, Figure 12), if equipped, from the filter (C).
6.
Wash the pre-cleaner (D, Figure 12) in liquid detergent and water. Allow the pre-
cleaner to air dry. Do not oil the pre-cleaner.
7.
Assemble the dry pre-cleaner (D, Figure 12), if equipped, to the filter (C).
8.
Install the filter (C, Figure 12) on the intake (E). Push the end of the filter into the
base. Make sure the filter fits securely in the base.
9.
Install the cover (B, Figure 12) and secure with the fastener(s) (A). Make sure the
fastener(s) is tight.
Service Fuel System
See Figure: 13
WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
• Keep fuel away from sparks, open flames, pilot lights, heat, and other ignition
sources.
• Check fuel lines, tank, cap, and fittings frequently for cracks or leaks. Replace if
necessary.
• Before cleaning or replacing the fuel filter, drain the fuel tank or close the fuel shut-
off valve.
• If fuel spills, wait until it evaporates before starting engine.
• Replacement parts must be the same and installed in the same position as the
original parts.
Fuel Filter, if equipped
1.
Before replacing the fuel filter (A, Figure 13), if equipped, drain the fuel tank or
close the fuel shut-off valve. Otherwise, fuel can leak out and cause a fire or
explosion.
2.
Use pliers to squeeze tabs (B, Figure 13) on the clamps (C), then slide 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 13) for cracks or leaks. Replace if necessary.
4.
Replace the fuel filter (A, Figure 13) with an original equipment replacement filter.
5.
Secure the fuel lines (D, Figure 13) with clamps (C) as shown.
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.
Fuel System
See Figure: 14
Store the engine level (normal operating position). Fill fuel tank (A, Figure 14) with fuel.
To allow for expansion of fuel, do not overfill 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 fuel stabilizer to the fuel as 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 fuel stabilizer 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. Run the engine until it stops from lack of fuel. The use of a
fuel stabilizer in the storage container is recommended to maintain freshness.
Engine Oil
While the engine is still warm, change the engine oil. See the Change Engine Oil
section.
