Engine Maintenance
Regular maintenance will improve the performance and
extend the life of the engine. Contact 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.
Follow the instructions and
schedule below.
Emission Control
Maintenance, replacement or repair of the emission
control devices and systems may be performed by
any nonroad engine repair establishment or

under the terms and provisions of the Briggs & Stratton

part repair or replacement must be performed by a
factory authorized dealer.
