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.

• 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.

• 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.

• Be sure to read the service instructions for the Front Drive System in conjunction with these service

instructions.
