ASSEMBLY
Tension the chain by turning the chain tensioning screw
clockwise using the combination spanner. The chain should
be tensioned until it does not sag from the underside of the
bar. See instructions under the heading Tensioning the chain.
The chain is correctly tensioned when it 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.
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.
