governor spring, linkages, or other parts to adjust the engine speed. If adjustments
are necessary, contact a Briggs & Stratton Authorized Service Dealer for servicing.
NOTICE
The equipment manufacturer specifies the maximum speed for the engine as installed
on the equipment. Do not exceed this speed. If you are not sure what the equipment
maximum speed is, or what the engine speed is set to from the factory, contact a Briggs
& Stratton Authorized Service Dealer for assistance. For safe and correct operation
of the equipment, the engine speed should only be adjusted by a qualified service
technician.

Servicing the Spark Plug

Check the spark plug gap (A, Figure 11) with a wire gauge (B). If necessary, set the
spark plug gap. Install and tighten the spark plug to the correct torque. For gap and
torque specifications, refer to the Specifications section.
NOTE: In some areas, it is mandatory by local law that you use a resistor spark plug
to decrease ignition signals. If a resistor spark plug was installed by the equipment
manufacturer, use the same type for replacement.
Servicing the Exhaust System
WARNING
During operation, the engine and muffler become hot. If you touch a hot engine,
thermal burns can occur.
Combustible materials, 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.
It is a violation of California Public Resource Code, Section 4442, to use or operate the
engine on any forest-covered, brush-covered, or grass-covered land unless the exhaust
system is equipped with a spark arrester, as defined in section 4442, maintained in
effective working order. Other states or federal jurisdictions may have similar laws;
reference Federal Regulation 36 CFR Part 261.52. Contact the original equipment
manufacturer, retailer, or dealer to obtain a spark arrester designed for the exhaust
system installed on this engine.
Remove debris from the muffler and cylinder area. Inspect the muffler for cracks,
corrosion, or other damage. Remove the deflector or the spark arrester, if equipped, and
inspect for damage or carbon blockage. If damage is found, install the replacement parts
before you operate the equipment.
WARNING
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.

Change Engine Oil

WARNING
Fuel and its vapors are flammable and explosive. Fire or explosion could result in
burns or death.
During operation, the engine and muffler become hot. If you touch a hot engine,
thermal burns can occur.
• If you drain the oil from the top oil fill tube, the fuel tank must be empty. If it is not
empty, fuel leakage can occur and cause a fire or an explosion.
• 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.
Used oil is a hazardous waste product and must be discarded of correctly. Do not
discard with household waste. Contact your local authorities, service center, or dealer
for safe disposal or recycling facilities.
Remove Oil
1. With the engine OFF but warm, disconnect the spark plug wire (D, Figure 12), and
keep it away from the spark plug (E).
2. Remove the oil drain plug (F, Figure 13). Drain the oil into an approved container.
NOTE: All of the oil drain plugs (G, Figure 13) can be installed in the engine.
3. Install and tighten the oil drain plug (F, Figure 13).
Add Oil
• Make sure the engine is level.
• Clean the oil fill area of all debris.
• Refer to the Specifications section for oil capacity.
1. Remove the dipstick (A, Figure 14). Remove oil from the dipstick with a clean cloth.
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.
Change Gear Reduction Oil
Some engines are equipped with a Gear Reduction Unit. If equipped, refer to the steps
for one of the Gear Reduction Units that follow.
2:1 Chain Reduction Unit
If the engine is installed with a 2:1 chain reduction unit (G, Figure 15), an oil change is
not necessary. The oil in the engine also lubricates the chain reduction unit.
6:1 Gear Reduction Unit
If your engine is equipped with a 6:1 gear reduction unit, do the steps that follow:
1. Remove the oil fill plug (A, Figure 16) and the oil level plug (B).
2. Remove the oil drain plug (C, Figure 16) and drain the oil into an approved
container.
3. Install and tighten the oil drain plug (C, Figure 16).
4. Slowly add gear reduction oil (80W-90) into the oil fill hole (D, Figure 16). Continue
to add the gear reduction oil (80W-90) until the oil comes out of the oil level hole
(E).
5. Install and tighten the oil level plug (B, Figure 16).
6. Install and tighten the oil fill plug (A, Figure 16).
NOTE: The oil fill plug (A, Figure 16) has a vent hole (F) and must be installed on the
top of the gear case cover as shown.

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.
Foam Air Filter
1. Loosen the fastener(s) (A, Figure 17).
2. Remove the cover (B, Figure 17), fastener (D) and washer (E).
3. Remove the foam element (C, Figure 17) from the air filter base (G).
4. Remove the support cup (F, Figure 17) from the foam element (C).
5. Clean the foam element (C, Figure 17) in liquid detergent and water. Squeeze dry
the foam element in a clean cloth.
6. Soak the foam element (C, Figure 17) in clean engine oil. To remove
the unwanted engine oil, squeeze the foam element with a clean cloth.
7. Install the support cup (F, Figure 17) into the foam element (C).
8. Install the foam element (C, Figure 17) to the air filter base (G) and onto the stud
(H). Make sure that the foam element is correctly assembled to the air filter base
with a washer (E) and fastener (D).
9. Install the cover (B, Figure 17) with the fastener(s) (A). Make sure that the
fastener(s) is tight.
Paper Air Filter
1. Loosen the fastener(s) (A, Figure 18).
2. Remove the cover (B, Figure 18) and fastener (E).
3. Slowly remove the pre-cleaner (D, Figure 18), if installed, and the air filter (C) from
the air filter base (F).
4. Lightly tap the air filter (C, Figure 18) on a hard surface. If the filter is dirty, replace
it.
5. Remove the pre-cleaner (D, Figure 18), if installed, from the air filter (C).
