Wear Inspection:

the chain. If the "Red Zone" (6) on the label
aligns with the "Arrow Mark" (7) on the
chain adjuster plates after the chain has
been adjusted to the proper slack, the chain
is excessively worn and must be replaced.
The proper slack is :
20 - 30 mm (0.8 - 1.2 in)
Damage to the bottom part of the frame
may be caused by excessive drive chain
slack of more than:
50 mm (2.0 in)
