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. See Emission Warranty on
page 17.
