1. Loosen the screw on the cutting head. (A)
2. Fit the cutting head on the shaft so that the screw (A)
is aligned with the hole in the shaft as shown.
3. Finger tighten the screw (A). Make sure that screw
(A) fits into the hole in the shaft.
4. Tighten screw (A).
5. Tighten screw (B).
To assemble the bar and chain
1. Unscrew the bar nut and remove the protective
cover.
2. 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.
3. Make sure that the edges of the cutting links are
facing forward on the top edge of the guide bar.
4. Fit the cover and locate the chain adjuster pin (A) in
the hole in the bar. Check that the drive links of the
chain fit correctly on the drive sprocket (B) and that
the chain is in the groove in the bar (C). Tighten the
bar nut finger-tight.

5. Tension the chain by turning the chain tensioning
screw clockwise using the combination spanner. The
chain should be tensioned until it does not sag from
the underside of the bar.
6. 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 nuts with the combination spanner.
7. 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.
