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 suf-
ficient oil to it, move the chain slowly to wash away
the filings before using again.

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.

These angles are referred to as 91PX. To sharp-
en other chains, follow chain manufacturer's
