User manual SHIMANO DH-3R30-N

[. . . ] 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 {177 ­ 310 lb. } (for the DH-3R35-H/DH-3R30-H) or 65 ­ 120 kg {144 ­ 265 lb. } (for the DH-3R35-N/DH-3R30-N). 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. [. . . ] 0. 8 mm Diameter 1. 8 ­ 2 mm CAUTION ­ To avoid serious injuries: Frame cable Lamp cable 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: Approx. 16 mm Bend the cable wires and run them along the grooves. NOTE: Carefully read the Front Inter-M Brake System Service Instructions for roller brakes in conjunction with these Service Instructions. 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. Use a 6 V/2. 4 W bulb for the front lamp and a 6 V/ 0. 6 W bulb for the taillamp. 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. 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. [. . . ] Connect the two wires to ensure that the current flows smoothly.
