Technical Service Instructions SI-5EV0B

FD-4400 Front derailleur

General Safety Information

• 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.
