• 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 it in oil.
