• 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,
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.
