• 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,
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.
