User manual SHIMANO DH-2R30-E

[. . . ] When the braking force reaches a certain level, the power modulator operates to prevent the braking force from going past that level. The recommended operating range for the power modulator is for bicycles with a gross weight (bicycle + rider + luggage) of 80 ­ 140 kg (176 ­ 308 lb. ) for the DH-2R35-E-H and 65 ­ 120 kg (144 ­ 265 lb. ) for DH-2R35-E/DH-2R30. If the gross weight of the bicycle is heavier than the recommended weight range, the braking force may be insufficient, and if it is lighter than the recommended weight range, the braking force may become too great and the wheels may lock and bicycle may fall over. [. . . ] 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 Connector cap (gray) Note: 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. It cannot be used for 6 V / 3 W specifications. Carefully read the Front Inter-M Brake System Service Instructions for roller brakes in conjunction with these Service Instructions. 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. Use a 6 V/ 2. 4 W bulb for the front lamp. 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 force the connection terminal to turn after the cap nut has been secured.
