CHAIN ADJUSTMENT
Chain should be checked, adjusted and lubricated as
per the Maintenance Chart to ensure safety and prevent
excessive wear. If the chain becomes badly worn or is
poorly adjusted (i.e., if it is too loose or too taut), it could
escape from sprocket or break.

the locking nut (2) of the wheel axle;
- adjust the linkages (3) on both sides of the swinging
arm using a 6 mm. Allen wrench;
- make sure the wheel axle is properly aligned using the
graduated scale (4) for reference;
- the operation done, tighten the wheel axle locking nut

After adjustment, always make sure that chain has a
slack of 12 mm (0.47 in.).
