links are facing forward on the top edge of
the guide bar.

tensioning screw clockwise using the
combination spanner. The chain should be

does not sag from the underside of the bar,
but can still be turned easily by hand. Hold
up the bar tip and tighten the bar nuts with
the combination spanner.
7. When fitting a new chain, the chain tension
has to be checked frequently until the
chain is run-in. Check the chain tension
regularly. A correctly tensioned chain
ensures good cutting performance and
long life.
