General Safety Information
r
WARNING
●
Obtain and read the service instructions carefully prior to installing the
parts.
Loose, worn, or damaged parts may cause serious injury to the rider.
We strongly recommend only using genuine Shimano replacement parts.
● The DH-T708/SM-AX60 can be used in combination with a special front
fork.If it is used in combination with any other front fork, it may cause
the wheel to become detached from the bicycle while you are riding and
result in serious bodily injury.
● Check that the wheels are fastened securely before riding the bicycle.
If the wheels are loose in any way, they may come off the bicycle and
serious injury may result.
● Check that the lamp illuminates normally when riding at nighttime.
● Read these Technical Service Instructions carefully, and keep them in a
safe place for later reference.
● Be sure to carefully read the Service Instructions for the disc brakes and
the SM-AX60.
CAUTION
The hub dynamo generates an extremely high voltage. Never touch the
connection terminal of the hub dynamo directly while riding the bicycle or
while the wheel is spinning. Touching the dynamo terminal may cause an
electric shock.
NOTE:
● Be sure to read these Service Instructions together with the Service
Instructions for the disc brake system.
● According to German regulations (StVZO), a hub dynamo in Germany
requires overvoltage protection. This hub dynamo (3.0 W) does not
have overvoltage protection inside the hub itself. Use an external
overvoltage protector with a symbol
to show that it complies with the German regulations (Shimano SMDH10 overvoltage protector or similar product).
● Check the degree of parallel of the front fork end. If the front fork end is
severely out of parallel, deformation of the hub axle may cause noise
from an obstruction inside the hub dynamo to be generated.
● Be sure to install the hub dynamo to the front fork so that the side with
the connection terminal is on the right when facing toward the front of
the bicycle. If the side with the connection terminal is facing toward the
left, the hub dynamo may not turn properly while riding.
● Check that the hub dynamo connection terminal is securely connected
before using the hub dynamo.
● Compatible bulbs

6.0V-3.0W ------
● If the bulb of either the front lamp or taillamp blows, excessive voltage
will be applied to the remaining lamp and shorten the operating life of
the bulb, so any blown bulbs should be replaced as soon as possible.
● Lamps with electrical circuits such as automatic lamps may become
damaged if the bicycle is ridden at high speeds.
● If the lamp is frequently turned on when riding at high speed ranges, it
will shorten the operating life of the bulbs.
● Do not disassemble the internal hub mechanism.
● Do not apply any lubricant to the inside of the hub, otherwise the grease
will come out and it may cause problems with conductivity.
● The hub dynamo will cause the turning of the wheel to become slightly
heavier because of the magnet inside the hub.
● Parts are not guaranteed against natural wear or deterioration resulting
from normal use.

Installation of the front wheel
Install the wheel so that the side with the hub dynamo connection
terminal is on the right side when looking toward the front of the
bicycle, and so that the hub connection terminal is aligned with the front
fork or with the basket stay. Then install by following the procedure
shown in the illustration below so that the connection terminal is facing
upward.
Do not force the connection terminal to turn after the E-Thru lever axle
has been secured. If you force the connection terminal to turn, it may
become damaged, or the wire inside the connection terminal may break.

If the position of the hub dynamo may change with
respect to the lamp while riding, for example when
Remove
using a suspension fork, make sure that the cable
is connected so that it will not be too loose or too
tight at any point within the range of movement.
To disconnect the lamp from the hub dynamo,
●
remove the connector cover.
● Do not ride the bicycle while the connector cover is
removed, otherwise the cable might get caught in
the bicycle wheel.
● When removing the bicycle wheel, fi rst remove the connector cover. If
the
cables are pulled strongly, it may break the cable wires or cause poor
contacts.
Furthermore, when installing the wheel, fi rst secure the wheel to the
front forks and then connect the connector cover.

These service instructions explain how to use and maintain the Shimano
bicycle parts which have been used on your new bicycle. For any
