ASSEMBLY
Fit the clutch cover and locate the chain adjuster pin in the
hole in the bar. Check that the drive 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 nuts finger
tight.
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.
