MAINTENANCE AND STORAGE
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 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 en-
gine 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 it in unusually wet or dusty conditions, consult your servicing dealer for
recommendations applicable to your individual needs and use.
