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 chainsaw, 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 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 opera-
tion, or use in unusually wet or dusty conditions, consult your servicing dealer for recommen-
dations applicable to your individual needs and use.
