Electronic Fuel Management System
The Electronic Fuel Management System monitors engine temperature, engine speed,
and battery voltage to adjust the choke during engine start-up and warm-up. There
are no adjustments on the system. If start-up or operation problems occur, speak to
a Briggs & Stratton Authorized Service Dealer.
NOTICE Make sure that you follow these rules or the Electronic Fuel Management
System could be damaged.
• DO NOT start the engine if the battery cables are loose.
• Before you connect the jump start cables, or disconnect or reconnect the battery
cables, turn the ignition switch to the OFF position. When you charge the
battery, turn the ignition switch to the OFF position.
• When you disconnect the battery cables from the battery, disconnect the
negative (- ) cable, and then disconnect the positive (+) cable to the battery.
When you connect the battery cables to the battery, connect the positive (+)
cable, and then the negative (-) cable to the battery.
• DO NOT use a battery charger to start the engine.
• DO NOT disconnect the battery cables during engine operation.
• DO NOT spray water directly on the Electronic Control Unit.
Carburetor and Engine Speed
Do not make adjustments to the carburetor, 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 7) with a wire gauge (B). If necessary, set the

Servicing the Exhaust and Cooling Systems
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.
This is an air cooled engine. Dirt or unwanted material can prevent air flow and cause
the engine to become too hot. This results in unsatisfactory performance and decreases
the life of the engine. The cylinder cooling fins can collect unwanted material that cannot
be remove without partial disassembly of the engine. Make sure that a Briggs & Stratton
Authorized Service Dealer examines and cleans the air cooling system. Refer to the
Maintenance Schedule.
1. Make sure that no combustible materials are around and behind the muffler.
2. Use a brush or dry cloth to remove all unwanted material from the blower housing
cover, muffler and cylinder area. DO NOT use water to clean the engine.
3. Make sure that the linkage, springs, and controls are clean.
4. Examine the muffler for cracks, corrosion, or other damage.
5. Remove the deflector or the spark arrester, if installed, and examine for damage or
carbon blockage. Make sure that you clean or install the replacement parts before
you operate the equipment.

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.
