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.

Proper filing tools for setting saw chain are avail-
able from your Echo dealer.

•  For setting saw chain, round file (33SL : 4.5 mm 

dia. or 20BPX, 95VP : 3/16 in.) and flat file are 

used.  

•  To keep correct position and correct angle,  

use the file holder (Sure Sharp
