Regular maintenance will improve the performance
and extend the life of the equipment. See any
Authorized Briggs & Stratton service dealer for
service. Use only original equipment replacement
parts. Other parts may not perform as well, may
damage the unit, and may result in injury. In
addition, use of other parts may void your warranty.
• Check the fasteners. Make sure all fasteners are
tight.
• Follow the information in the Maintenance section
to keep the unit in good operating condition.
Unintentional sparking can result in
fire or electric shock.
Unintentional start-up can result in
entanglement, traumatic amputation,
or laceration.

• Do not tamper with governor spring, links or
other parts to increase engine speed.

hard object because the flywheel may later
shatter during operation.
