•  Place the depth gauge tool firmly on guide bar 

so that depth gauge protrudes.  
Then file top of depth gauge with the flat file until 
flat with top of the depth gauge tool. 

-  Be sure to round off the front edge of the 

depth gauge.

Properly filed cutters are shown in illustration. 

When setting of the chain is finished, soak it in oil 
and wash away filings completely before using. 

-  When chain has been filed on the bar,  

supply sufficient oil to it, rotate the chain 
slowly to wash away the filings before using 
again. 

-  If the chain saw is operated with filings 

clogged in the groove, the saw chain and the 
guide bar will be damaged prematurely. 

-  If the saw chain becomes soiled with resin, for 

instance, clean it with kerosene and soak in it 
oil.
