Properly filed cutters are shown as 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.

The following guide bars may be considered to have equivalent kickback energy.
∙Sprocket nose guide bars of the same length and nose radius, same pitch and having the same number of teeth.
∙A hard nose guide bars of the same length and nose radius as a sprocket nose bar.
SAW CHAIN
CAUTION
Do not use replacement saw chain unless it has been designated as meeting the ANSI B 175.1- 2000 kickback performance requirements.
