Maintenance and repair
You can see the elongation of
the chain through the slot (A)
in the protective case.
The lever (B) of the chain
tensioner moves from the
top (new/shortened chain)
downwards (elongated chain)
as the chain length increases.
If the lever is no longer visible
in the slot, the chain must be
shortened. Replace the chain
if the permissible elongation
of the chain (= 3% of the
original length) is exceeded.
You can see the length of
the chain at the level of
the tensioning lever (X)
of the chain tensioner.
The tensioning lever (X)
moves from the top
(new/shortened chain)
downwards (elongated chain)
as the chain length increases.
When the tensioning lever (X)
is in the lowest position,
the chain must be shortened.
Replace the chain if the
permissible elongation of
the chain (= 3% of the
original length) is exceeded.
