ASSEMBLY

Tension the chain by turning the wheel down (+). The chain should be tensioned until it does not sag from the underside of the bar.

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 clutch by turning the knob clockwise.

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.
