ENGINE MAINTENANCE
Refer to engine emission warranty included with your product
for maintenance schedule.
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 in-
clude 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 con-
ditions. 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 servic-
ing dealer for recommendations applicable to your individual
needs and use.
