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.)

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 Spark Plug
●
Check the spark plug gap (A, Figure 10) 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.
