When chain has been filed on the
bar, supply sufficient oil to it, move
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.
To sharpen other chains, follow chain manufacturer’s instructions.
