MAINTENANCE AND STORAGE
Refer to Table 2. Maintenance Schedule, 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 a maintenance schedule, 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.
