links of the chain fit correctly over the drive sprocket
and that the chain is correctly located in the groove in
the bar. Tighten the bar nut with your fingers.

screw clockwise using the combination spanner. The
chain should be tensioned until it does not sag from
the underside of the bar. (42)

slack on the underside of the bar, and it can still be
turned easily by hand. Tighten the bar nut with the
combination spanner while holding up the tip of the
bar. (43)
• 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. (44)
