TO ENSURE SAFETY

Be sure to also inform users of the following:

For installation to the bicycle and maintenance

Be sure to follow the instructions provided in the manuals when installing the product.

Only use SHIMANO genuine parts. If a component or replacement part is incorrectly assembled or adjusted, it

can lead to component failure and cause the rider to lose control and crash.

Wear approved eye protection while performing maintenance tasks such as replacing components.

Be careful not to let the hemming of your clothes get caught in the chain while riding. Otherwise, you may

fall off the bicycle.

When operating the shift switch, be careful not to allow your fingers to be caught in the derailleur. The motor

in the derailleur is powerful enough to be operated without stopping until the shifting position is reached,

and may cause serious injury if your fingers interfere with the shifting motion.

Be sure to also inform users of the following:

For installation to the bicycle and maintenance

Be sure to rotate the crank arm when carrying out any operations which are related to gear shifting.

The connectors are small and waterproof, so do not connect and disconnect electric wires except when

necessary. Doing so may impair the waterproofing.

Be careful not to get water into the E-TUBE ports.

The components are designed to be fully waterproofed to withstand wet weather riding conditions; however,

do not deliberately place them into water.

Do not clean the bicycle in a high-pressure wash. If water gets into any of the components, operating

problems or rusting may result.

Be sure to keep rotating the crank arm during gear shifting operations.

Handle the components carefully, and avoid subjecting them to strong shock.

Do not use the thinners or harsh solvents to clean the products. Such solvents may damage the surface.

If gear shifting operation does not feel smooth, consult the place of purchase for assistance.

Keep away from magnetic objects. If this is not observed, problems with operation may occur.

When installing a product that uses a magnet, make sure the magnet is set in the specified location before

installing the product.

Contact the place of purchase for updates of the component software. The most up-to-date information is

available on the SHIMANO website.

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.

Be sure to attach dummy plugs to any unused E-TUBE ports.

Be sure to use the SHIMANO original tool TL-EW300 to remove and install the electric wires.

The clamp band, clamp screw and clamp nut are not compatible with other products. Be sure to always use

the clamp band, clamp screw or clamp nut which is specific to each product.

Electric wires/electric wire covers

Secure the electric wires with a zip tie so that they do not interfere with the gears or tires, etc.

The strength of the adhesive is fairly weak to prevent the paint on the frame from being peeled off when

removing the electric wire cover, such as when replacing the electric wires. If the electric wire cover is peeled

off, replace it with a new one. When removing the electric wire cover, do not peel it off too vigorously. If so,

the paint on the frame will peel off, too.

Do not remove the wire holders which are attached to the internal type electric wires (EW-SD300-I). The wire

holders prevent the electric wires from moving inside the frame.

When installing to the bicycle, do not forcibly bend the electric wire plug. It may result in a poor connection.

and length adjustment. If the front derailleur is accidentally triggered while performing a

maintenance procedure, your fingers could get caught in the front derailleur and be injured.
