Possible signs of wear on chain drive components
Chain ring and sprocket
If the teeth on the chain ring and/or the sprocket are worn due to material abrasion, move-
ment of the chain on the corresponding gear wheel is not as reliable and it can slip off easily.
Chain and chain links
If the chain links are worn because of material abrasion, the free openings between them
that interlock with the teeth widen. Movement of the chain on the corresponding gear
wheel is thus not as reliable and it can slip off easily. You may also have the impression that
the chain has stretched.
Check chain rings, sprockets and chain regularly for signs of wear.
• Contact your specialist dealer to replace worn chain rings or sprockets.
• Contact your specialist dealer to adjust the chain correctly or replace it if you have the
impression that the chain has widened or if you notice signs of wear on the chain links.

Cleaning and care
Make sure that the chain drive components are free from any soiling and clean the compo-
nents regularly to ensure that the chain drive functions correctly.
• Clean the chain using a clean cloth with a dab of oil applied, if required.
• If necessary, clean the gear wheels with a soft brush.
•
Lubricate the chain with universal oil:
-
after you have cleaned the chain,
-
if the chain has become excessively wet,
-
at regular intervals, after roughly 15 hours of operation.
• Contact your specialist dealer if the chain drive components are showing tougher signs
of soiling or if you notice that chain drive components are damaged.
