Operator`s manual

Introduction/Contents
Your chainsaw is only as good as your chain, guide bar,
and sprocket. They function as a team while cutting wood
and must be maintained as a team.
A properly maintained chain, bar, and sprocket will provide
excellent cutting performance. An improperly maintained
chain will cause damage to the bar and sprocket, will cut
poorly, and will create potential safety hazards.
This manual addresses the maintenance of only Oregon
®
manufactured chains, bars, and sprockets. For information on
maintenance and operation of your saw, refer to your saw’s
operator’s manual or contact your local chainsaw dealer.
