General Safety Information
WARNING
• Obtain and read the service instructions carefully prior to installing the parts. Loose,
worn, or damaged parts may cause injury to the rider.
We strongly recommend only using genuine Shimano replacement parts.
• Be careful not to let the cuffs of your clothes get caught in the chain while riding,
otherwise you may fall off the bicycle.
• Read these Technical Service Instructions carefully, and keep them in a safe place for
later reference.
Note
• If gear shifting operations cannot be carried out smoothly, clean the derailleur and
lubricate all moving parts.
• If the amount of looseness in the links is so great that adjustment is not possible, you
should replace the derailleur.
• When the chain is in the position shown in the illustration,
the chain may contact the front chainrings or front derailleur
and generate noise. If the noise is a problem, shift the chain
onto the next-larger rear sprocket or the one after.
• For smooth operation, use the specified outer casing and
the bottom bracket cable guide.
• Grease the inner cable and the inside of the outer casing
before use to ensure that they slide properly.
• Parts are not guaranteed against natural wear or deterioration resulting from normal
use.
• For maximum performance we highly recommend Shimano lubricants and
maintenance products.
• For any questions regarding methods of installation, adjustment, maintenance or
operation, please contact a professional bicycle dealer.
In order to realize the best performance, we recommend that the following
combination be used.
