TO ENSURE SAFETY
WARNING
••When installing components, be sure to follow the instructions that are given in the instruction manuals.
It is recommended to use genuine Shimano parts only. If parts such as bolts and nuts become loose or damaged, the bicycle may
suddenly fall over, which may cause serious injury.
In addition, if adjustments are not carried out correctly, problems may occur, and the bicycle may suddenly fall over, which may
cause serious injury.
•• Be sure to wear safety glasses or goggles to protect your eyes while performing maintenance tasks such as replacing parts.
••After reading the dealer's manual thoroughly, keep it in a safe place for later reference.
Be sure to also inform users of the following:
•• Be careful not to let the hemming of your clothes get caught in the chain while riding. Otherwise you may fall off the bicycle.
NOTE
Be sure to also inform users of the following:
•• If gear shifting operations cannot be carried out smoothly, clean the derailleur and lubricate all moving parts.
•• 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-largest rear sprocket or the one after.

•• Products are not guaranteed against natural wear and deterioration from normal use and aging.
•• For maximum performance we highly recommend Shimano lubricants and maintenance products.
For Installation to the Bicycle, and Maintenance:
•• Use an OT-SP cable and cable guide for smooth operation.
•• If the amount of looseness in the links is so great that adjustment is not possible, you should replace the derailleur.
The actual product may differ from the illustration because this manual is intended mainly to explain the procedures for
using the product.

„ Brazed-on type
If installing the front derailleur to a brazed-on type frame, a backup plate must be attached to the seat tube. Always be sure to
install the backup plate in order to prevent damage to the frame from the pressure applied by the support bolt of the front
derailleur.
Installation of the backup plate
Check the position where the support bolt directly touches the frame when the support bolt of the front derailleur is being
adjusted, and attach the backup plate in that position. In addition, avoid positioning the tape that attaches the backup plate to
the seat tube in the location where the support bolt directly touches the frame.
* When the mounting band adapter (SM-AD90/79/67)
is used, the support bolt and the backup plate are
not required.

ADJUSTMENT
„„Connection and securing of inner cable
Adjusting the cable route
The distance of the movement of the front derailleur varies according to the end point of the cable guide or the position of the
hole in the frame through which the cable is passed. Adjust the distance of the movement by turning ON/OFF the converter.

How to turn ON/OFF the converter
The protrusion on the converter and the dent beside it serve as a guide.
•• The protrusion is on the outer side of the bicycle: OFF
•• The protrusion is on the inner side of the bicycle: ON
(Either ON or OFF can be selected if the cable is on the center line.)
