MAINTENANCE SCHEDULE
MAINTENANCE AND STORAGE
Please read the maintenance schedule, found in the
accompanying combined exhaust and evaporative emissions
control warranty statement, and observe these recommended
care operating intervals to extend the life of your engine.
Good maintenance is essential for safe, economical, and
trouble-free operation. It will also help reduce air pollution.
To help you properly care for your engine, the following
pages include routine inspection procedures and simple
maintenance procedures using basic hand tools. Other service
tasks that are more dicult, or require special tools, are best
handled by professionals and are normally performed by a
technician or other qualied mechanic.
Maintenance, replacement or repair of the emissions
control devices and systems may be performed by any
non-road engine repair establishment or individuals.
However, items must be serviced by an authorized dealer
to obtain "no charge" emissions control warranty service.
The maintenance schedule applies to normal operating
conditions. If you operate your engine under unusual
conditions, such as sustained high-load or high-temperature
operation, or use in unusually wet or dusty conditions, consult
your servicing dealer for recommendations applicable to your
individual needs and use.
