SHARPENING THE SAW CHAIN

The saw chain must be sharpened to the manufacturer's
specifications. If the saw chain is not properly sharp-
ened, the risk of kickback increases.
See Illustration:
Saw Chain Pitch
See Figure A. Pitch refers to the saw chain measure-
ment. A chain's pitch is the distance between any three
consecutive rivets divided by two. Example: .65 divided
by two equals .325 pitch.
This distance divided
by two equals Pitch "A".
