Troubleshooting - Echo CS-400 Operator's Manual

CS-400
• 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.
