[. . . ] SI-20M0E-003-00 General Safety Information WARNING ­ To avoid serious injuries: Compatible bicycles are those with 26-28 inch wheels (for the DH-2R35/DH-2R30-E hub dynamos) or 16-20 inch wheels (for the DH-2R30-ES hub dynamo). If the hub dynamo is used with wheels which are smaller than 26 inches (for the DH-2R35/DH-2R30-E) or 16 inches (for the DH-2R30-ES), the braking force may be too great, which could cause the wheels to lock and the bicycle to lose its balance and fall over. The hub of the DH-2R35/DH-2R30 has a built-in power modulator which controls the braking force to prevent it from being too great. [. . . ] If the cables are connected incorrectly, the lamp will not illuminate. Twist the cable wires before connecting them so that they stay together. Recommended wire specifications Wire Insulation Lamp connection terminal Type Wire Insulation Stranded Size (AWG) 22 Diameter approx. 0. 8 mm Diameter 1. 8 ­ 2 mm Frame cable Lamp cable CAUTION ­ To avoid serious injuries: Approx. 16 mm Bend the cable wires and run them along the grooves. 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. Insert Bend NOTE: This hub dynamo is rated for 6 V/ 2. 4 W specifications. Carefully read the Front Inter-M Brake System Service Instructions for roller brakes in conjunction with these Service Instructions. 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. If the lamp is frequently turned on when riding at high speed ranges, it will shorten the operating life of the bulbs. 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. Connector cover (black) Groove Note: Set so that it faces the right way. Do not allow the cable wires to touch each other. Press in until you hear a click. Hub dynamo connection terminal Frame connection terminal Lamp connection terminal 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. [. . . ] For any questions regarding your bicycle or other matters which are not related to Shimano parts please contact the place of purchase or the bicycle manufacturer. * Service Instructions in further languages are available at : http://techdocs. shimano. com Please note: Specifications are subject to change for improvement without notice. (English) Note: When tightening the cap nuts, tighten the nuts alternately on both sides and do not concentrate all of the effort for tightening and loosening the cap nut on one side of the wheel only, otherwise the hub axle may turn, which could excessively tighten or loosen the lock nuts.
