ASSEMBLY
Fit the bar over the bar bolts. Place the bar in its rearmost
position. Place the chain over the drive sprocket locate it in
the groove on the bar. Begin on the top edge of the bar.
Make sure that the edges of the cutting links are facing
forward on the top edge of the bar.
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.
Tension the chain by turning the wheel down (+).
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.
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.
