General Safety Information

WARNING

• Be careful not to let the cuffs of your clothes get caught in the chain
while riding, otherwise you may fall off the bicycle.

• Obtain and read the service instructions carefully prior to installing
the parts. Loose, worn or damaged parts may cause the bicycle to fall
over and serious injury may occur as a result. We strongly recommend
only using genuine Shimano replacement parts.

• Obtain and read the service instructions carefully prior to installing
the parts. If adjustments are not carried out correctly, the chain may
come off and this may cause you to fall off the bicycle which could result
in serious injury.

• Read these Technical Service Instructions carefully, and keep them in a
safe place for later reference.

Note

• If gear shifting operations do not feel smooth, wash 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.

• Shimano does not provide the bottom bracket mount fixing bolts.

• For smooth operation, use the specified outer casing and the bottom
bracket cable guide.

• 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.
