ASSEMBLY
Fitting the cutting head
• Fit the cutting head on
the shaft so that the screw
(A) is aligned with the
hole in the shaft as
shown.
• Tighten screw A.
• Tighten screw B.
NOTE! Make sure that
the drive shaft inside the
shaft engages with the
cut-out in the cutting
head.
Mounting guide bar and chain
• Unscrew the bar nut and
remove the guard.
• Fit the bar over the bar
bolt.Place the bar in its
rearmost position. Place
the chain over the drive
sprocket and in the
groove on the bar. Begin
on the top side of the bar.
• Make sure that the edges
on the cutting links are
facing forward on the top
side of the bar.
• Fit the clutch cover and
locate the chain adjuster
pin in the hole on the bar.
Check that the drive links
of the chain fit correctly
on the drive sprocket and
that the chain is in the
groove on the bar.
Tighten the bar nut finger
tight.
• Tension the chain by
using the combination
wrench. Turn the chain
adjuster screw clockwise.
The chain should be
tensioned until it fits
snugly on the underside
of the bar.
• The chain is correctly
tensioned when there is no
slack on the underside of the
bar, but it can still be turned
easily by hand. Hold up the
bar tip and tighten the bar
nuts with the combination
wrench.
• 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
gives good cutting
performance and long
lifetime.
