Maintenance
Maintenance Information
WARNING
During maintenance if it is necessary to tilt the unit, make sure that the fuel tank, if
mounted on the engine, is empty and that the spark plug side is up. If the fuel tank is not
empty, leakage can occur and could result in a fire or an explosion. If the engine is tilted
in a different direction, it will not easily start because of oil or fuel contamination of the air
filter or the spark plug.
We recommend that you see a Briggs & Stratton Authorized Service Dealer for all
maintenance and servicing of the engine and engine parts.
NOTICE
All the components used to build this engine must remain in place for correct operation.
WARNING
Accidental engine spark can cause an electric shock or fire and could result in
entanglement, traumatic amputation or laceration.
Before you make adjustments or repairs:
• Disconnect the spark plug wire and keep it away from the spark plug.
• Disconnect the battery wire from the negative battery terminal (only engines with
electric start.)
• Use only the correct tools.
When you check for spark:
• Use an approved spark plug tester.
• Do not check for spark with the spark plug removed.
Emissions Control Service
For maintenance, replacement, or repair of emissions control devices and
systems, contact a qualified off-road engine repair establishment or service
technician. However, for "no charge" emissions control service, the work must be done
by a factory authorized dealer. Refer to the Emissions Control Statements.

Carburetor and Engine Speed
Do not make adjustments to the carburetor or engine speed. The carburetor was
set at the factory to operate satisfactorily in most conditions. Do not change the
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 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.
Servicing the Spark Plug
Check the spark plug gap (A, Figure 12) 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.
™
and No
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.
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.
™
