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 the Saw Chain

• For setting saw chain, round file 

(5/32 in. diameter) and flat file are 

used.

• Push file as shown.

• To keep correct position and 

correct angle, use a file holder.
