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.

•  For setting saw chain, round file (4.0 mm dia.  

5/32 in.) and flat file are used.  

•  To keep correct position and correct angle,  

use the file holder (Sure Sharp

).
