GASOLINE ENGINE
A manufacturer of an aftermarket part assumes the responsibility that the part will not adversely affect emission performance. The
manufacturer or rebuilder of the part must certify that use of the part will not result in a failure of the engine to comply with
emission regulations.
Maintenance
Follow the maintenance schedule. Remember that this schedule is based on the assumption that your machine will be used for its
designed purpose. Sustained high-load or high-temperature operation, or use in unusually wet or dusty conditions, will require
more frequent service.
