cover after adjusting the chain tension. Make sure that
the saw chain does not loose at lower side.

CAUTION:
• Do not tighten the saw chain too much.
Excessively high tension of saw chain may
cause breakage of saw chain, wear of the guide
bar and breakage of the adjusting dial.
• A chain which is too loose can jump off the bar,
and therefore presents an accident risk.

saw chain in a clean place free from sawdust
