For Installation to the Bicycle, and Maintenance:
• This is a small waterproof connector. Do not repeat connecting and disconnecting it. It may impair the function.
• Be sure to attach dummy plugs to any unused terminals.
• The units are designed to be fully waterproof to withstand wet weather riding conditions. However, do not deliberately
place them into water.
• Always be sure to use the TL-EW02 special tool to remove the electric wires.
• If the chain keeps coming off the sprockets during use, replace the sprockets and the chain.
• Do not disassemble, otherwise operating problems will result.
• The motors of the front derailleur and the rear derailleur cannot be repaired.
• Contact Shimano for information regarding the shipment of the battery charger to South Korea and Malaysia.
<EW-SD50/EW-SD50-I: Electric Wires / SM-EWC2: Electric Wire Covers>
• Secure the electric wires with cable ties so that they do not interfere with the chainrings, sprockets and tires.
• The strength of the adhesive is fairly weak, to prevent the paint on the frame from being peeled off at the same time when
removing the electric wire cover for reasons such as 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 this is not observed, the paint on the frame will
peel off too.
• Do not remove the wire holders which are attached to the built-in type electric wires (EW-SD50-I). The wire holders prevent
the electric wires from moving inside the frame.
<ST-6770: Dual Control Lever>
• SW-R610 cannot be used with ST-6770 because the shape of its connector is different from that of E-tube.
• Dummy plugs are installed at the time of shipment from the factory. Do not remove them except when necessary.
• When routing the electric wires, take care to ensure that they do not interfere with the brake levers.
<RD-6770: Rear Derailleur>
• Always be sure to adjust the top adjustment bolt and the low adjustment bolt according to the instructions given in the
adjustment section. 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.
• If gear shifting adjustment cannot be carried out, check the degree of parallelism at the rear end of the bicycle. Also check
if the cable is lubricated and if the outer casing is too long or too short.
• The tension pulley has an arrow on it to indicate the direction of rotation. Install the tension pulley so that the arrow is
pointing clockwise when looking at the outer side of the derailleur.
