General Safety Information

WARNING

– To avoid serious injuries:

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.

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.

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:

According to German regulations (StVZO), a hub dynamo in Germany requires

overvoltage protection. This hub dynamo 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 SM-DH10 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.

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

Front lamp

Taillamp

6.0 V/ 2.4 W

6.0 V/ 0.6 W

6.0 V/ 3.0 W

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.

Technical Service Instructions

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 quick release lever has been secured.

Note:

The toothed axle washer is not necessary

for a quick release type.

Connect the two wires to ensure that the

current flows smoothly.

Do not switch over the frame cable and the lamp cable

by mistake. If the cables are connected incorrectly, the

lamp will not illuminate.

Twist the cable wires before connecting them so that

they stay together.

Note:

Secure the cable to the front fork or the basket stay so that it will not

get caught in the spokes or any other parts while riding. If the

position of the hub dynamo may change with respect to the lamp

while riding, for example when 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.

Connect so that the current from the hub dynamo flows through the

cable from the lamp connection terminal of the hub dynamo to the

frame connection terminal.

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, first 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, first secure the wheel to the front forks and then connect the

connector cover.

Checking the lamp illumination

Rotate the front wheel and check that the

lamp illuminates.

These service instructions explain how to use and maintain the Shimano bicycle parts which have been

used on your new bicycle. For any questions regarding your bicycle or other matters which are not related to
