The teeth of the top part must be oriented as shown
in the diagram.
ATTENTION !! Make sure to match the chain teeth

to achieve initial light tension (fig. 9).
9) Fit the chain cover back on and tighten the nuts by
hand.

er tension has been reached, the chain can be raised
with two fingers to the point where an entire guide
tooth is visible (Fig. 9 part. A).
11) Fully tighten the two nuts with the key provided (Fig.
10) keeping the point of the bar raised. Check that
the chain can run freely in the bar.
NOTE!! The tension of a new chain must be checked
and set (with the engine off and the brake on) after a few
minutes of work.
