2. Open the chain access cover (12) by using the

supplied wrench. To open turn the access cover nut

1/4 turn anti-clockwise. (See Fig. C)

3. Release tension on the chain by loosening the chain

tensioner bolt (15). Turn the chain tensioner bolt anti-

clockwise 2 or more times. (See Fig. D)

4. Re-tighten the chain tensioner bolt by turning the

chain tensioner bolt. When tightening the chain

tensioner bolt the automatic chain tensioning system

will set the tension to the chain at the same time.

5. Check that the correct chain tension has been set.

It should be possible to pull the chain away from the

side of the bar approximately 3mm and it should snap

back. (See Fig. E)

If tension is incorrect, repeat step 3, ensuring the bar

is free to move when the tensioner is released.
