Engine Maintenance
Please read the maintenance schedule and observe these
recommendations 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 difficult, or
require special tools, are best handled by professionals and
are normally performed by a technician or other qualified
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 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.
