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.

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.
To adjust the harness
You should always use the harness with the machine to
give maximum control over the machine and reduce the
risk of fatigue in your arms and back.
1. Put on the harness.
2. Hook the machine onto the harness support hook.
3. Adjust the length of the harness so that the support
hook is roughly level with your right hip.
