Regular maintenance will improve the performance and extend the life of the engine. See any Authorized Briggs

&Stratton Dealer for service. Use only genuine

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.

CAUTION

All the components used to build this engine assembly must remain in place for the proper operation of this engine.
