• This dealer’s manual is for use with the ULTEGRA 6770 series (electronic gear shifting system) only. For any information regarding
the ULTEGRA 6700 series which does not appear in this manual, refer to the Service Instructions included with each component.
• 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, otherwise your fingers may become
stuck.
• When installing components, be sure to follow the instructions which are given in the dealer’s manual. It is recommended that
you use only genuine Shimano parts at this time. In addition, if parts such as bolts and nuts become loose or damaged, the bicycle
may suddenly fall over and serious injury may occur as a result.
• When installing components, be sure to follow the instructions which are given in the dealer’s manual. If adjustments are not
carried out correctly, problems may occur such as the chain coming off, and the bicycle may suddenly fall over and serious injury
may occur as a result.
• After reading this dealer’s manual thoroughly, keep it in a safe place for later reference.
If charging is not complete after 1.5 hours of charging time
has elapsed, stop the charging.
If this is not observed, fire, bursting or overheating may
occur.
Do not place the battery into fresh water or sea water, and
do not allow the battery terminals to get wet.
The operating temperature ranges for the battery are given
below. Do not use the battery in temperatures outside
these ranges.
1. During discharge: –10°C - 50°C
2. During charging: 0°C - 45°C
If the battery is used or stored in temperatures which are
outside these ranges, fire, injury or problems with
operation may occur.
Do not use the battery if it has any noticeable scratching or
other external damage.
If this is not observed, bursting, overheating or problems
with operation may occur.
Do not subject the battery to strong shocks or throw it.
Do not use the battery if leakages, discoloration,
deformation or any other abnormalities occur.
If any leaked fluid gets on your skin or clothes, wash it off
immediately with clean water.
The leaked fluid may damage the skin.
Do not use or place the battery at or near sources of fire.
If this is not observed, sparking, bursting, fire or electric
shocks may result.
Do not recharge the battery in places which have high
humidity or outdoors.
Do not insert or remove the plugs while they are wet. If the
insides of the plugs are wet, dry them thoroughly before
inserting them.

Be sure to hold the power cable by the power plug when
connecting and disconnecting the power plug from the
electrical outlet.
If you do not hold the power cable by the power plug, fire
or electric shocks may occur.
* If heat or acrid-smelling smoke is coming out from the
power plug.
* There may be a bad connection inside the power plug.
Do not overload the electrical outlet with appliances
beyond its rated capacity, and use only a 100 – 240 V AC
electrical outlet.
If the electrical outlet is overloaded by connecting too
many appliances using adapters, overheating resulting in
fire may occur.
Do not damage the power cord or power plug. (Do not
damage, process, forcibly bend, twist or pull them, bring
them near hot objects, place heavy objects on them or
bundle them tightly together.)
If they are used while damaged, fire, electric shocks or
short-circuits may occur.
Do not use the charger with commercially-available
electrical transformers designed for overseas use.
If this is not observed, they may damage the charger.
Always be sure to insert the power plug as far as it will go.
If this is not observed, fire may occur.

• The two left crank arm mounting bolts should be tightened alternately in stages rather than each bolt being fully tightened all at
once. Use a torque wrench to check that the final tightening torques are within the range of 12 - 14 N·m. Furthermore, after
riding approximately 100 km (60 miles), use a torque wrench to re-check the tightening torques. It is also important to
periodically check the tightening torques. If the tightening torques are too weak or if the mounting bolts are not tightened
alternately in stages, the left crank arm may come off and the bicycle may fall over, and serious injury may occur as a result.
• If the inner cover is not correctly installed, corrosion of the axle may occur, and this may damage the axle and the bicycle may fall
over, and serious injury may occur as a result.
• Before riding the bicycle, check the crank arms thoroughly to see if they contain any cracks. If the crank arms are cracked, they
may break and you may fall off the bicycle.
