Maintenance
Regular maintenance will improve the performance and
extend the life of the engine. See any Authorized Briggs
& Stratton Dealer for service. Use only genuine Briggs
& Stratton parts. Other parts may not perform as
well, may damage the engine, and may result in
injury. In addition, use of other parts may void your
warranty.
Emission Control
Maintenance, replacement or repair of the emission
control devices and systems may be performed by
any nonroad engine repair establishment or
individual. However, to obtain no charge repairs under
the terms and provisions of the Briggs & Stratton
warranty statement, any service or emission control part
repair or replacement must be performed by a factory
authorized dealer.
Wear eye protection when doing
repair work.
Frostbite can result from skin/eye
contact with leaking LP liquid.
WARNING
• Installation, adjustment and repair work should
be done by a qualified technician.
• Flexible supply lines should be checked
regularly to make sure they are in good
condition. Replace damaged or leaking
components.
Before performing maintenance or repairs:
• Disconnect spark plug wire and keep it away
from spark plug.
• Disconnect battery at negative terminal (only
engines with electric start).
• Use only correct tools.
• Do not strike the flywheel with a hammer or
hard object because the flywheel may later
shatter during operation.
• Do not tamper with governor spring, links or
other parts to increase engine speed.
When testing for spark:
• Use approved spark plug tester.
• Do not check for spark with spark plug
removed.
Unintentional sparking can result
in fire or electric shock.
Fire or explosion can cause
severe burns or death.
