Setting The Saw Chain

Important points for proper maintenance of saw chain:

• Keep the cutters sharp at all times.

• Keep the left and the right cutters properly aligned.

• Note that blunt or irregular cutters will result in poor cutting performance,

increased vibration of chains and premature breakage of the saw chain.

• Drive link serves to remove

sawdust from the groove of the

guide bar. Keep the lower edge of

the drive link sharp where

indicated.

Setting Saw Chain

• For setting saw chain, round file

(4.0 mm [5/32 in.] diam.) and flat

file are used.

• Push file as shown.
