underside of the bar. (12)
Whether the groove in the bar has become badly worn.
Replace the bar if necessary. (16)
Whether the tip of the bar is uneven or badly worn. If a
hollow forms on the underside of the bar tip this is due
to running with a slack 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 knob by
turning the knob clockwise. (13)

To prolong the life of the bar you should turn it over daily.
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. (20)
