TO ENSURE SAFETY
WARNING
• When installing components, be sure to follow the instructions that are given in the instruction manuals.
It is recommended that you use only genuine Shimano parts. 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:
• When the shifting switch is operated, the motor which drives the front derailleur will operate without stopping at the shifting
lever position. Always be sure to disconnect the battery before carrying out installation and adjustments, otherwise your
fingers may become stuck.
• Install in a place where it will not obstruct the operation of the brake lever.
NOTE
Be sure to also inform users of the following:
• Be sure to keep turning the crank during the lever operation.
• Be careful not to let water get into the terminals.
• 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:
• Always be sure to adjust the top adjustment bolt and the low adjustment bolt according to the ULTEGRA 6770 dealer's manual.
If these bolts are not adjusted, the chain may become clamped between the spokes and the large sprocket and the wheel may
lock, or the chain may slip onto the small sprocket.
• Always be sure to use the TL-EW02 special tool to remove the electric wires.
• When routing the electric cable, make sure that it does not interfere with the operation of the brake lever.
• If the component configuration changes or malfunction is observed, use the E-tube Project software to update the firmware of
each component to the latest version and perform a check again. Also make sure that the E-tube Project software is the latest
version. If the software is not the latest version, the component compatibility or the product functions may not be sufficiently
available.
The actual product may differ from the illustration because this manual is intended chiefly to explain the procedures for
