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.
