Be sure to observe the following when using the Auto-. If this is not done, incorrect operations such as unwanted gear shifting may occur while riding, and this might lead to your feet coming off the pedals and the bicycle falling over. 1) WARNING Check that the motor unit and the connector are securely installed with the connector fixing bolts so that there is no gap between them. If there is a gap between the motor unit and the connector, vibration may occur or water may get inside, and this may cause incorrect signals to be output.

SENSOR 4. Installing the speed sensor Installation position Install the speed sensor to the left-side chainstay of the rear wheel, in a position as close to the hub as possible. Install the speed sensor close to the hub. Installing the magnet Install the magnet to one of the wheel spokes so that the magnet is aligned with one or other of the two lines on the speed sensor. Install the magnet so that there is a clearance of 2 6 mm between the magnet and the speed sensor at this time. Speed sensor 2 lines Installing the speed sensor Gently wrap the speed sensor cable twice around the stay so that the cable then points toward the front of the bicycle. Next, place the pad in between the speed sensor and the chainstay, and then tighten the speed sensor fixing bolt so that the speed sensor will not turn. agnet 1 Nm {10 kgfcm} agnet fixing bolt Spacer Spoke 1 Nm {10 kgfcm} Speed sensor fixing bolt Cable Spoke side o not forget to install the spacer, otherwise the magnet fixing bolt will loosen and the magnet will fall off the spoke. agnet Speed sensor Speed sensor Chainstay agnet Pad SENSOR Leave a clearance of 2 6 mm between the speed sensor and the magnet. 5

For reversed fork end When mounting the chain on the sprocket, remove the chain from the chainring in order to protect the motor unit. After mounting the chain on the sprocket and setting the hub axle into the fork ends, place the chain back onto the chainring. Hub axle Fork end otor unit 2. Install the motor unit to the hub so that the mark (yellow) on the motor unit is aligned with the mark (yellow) on the hub lock spacer. After this, gently push the motor unit while turning it slowly to set it correctly until it stops turning on the hub axle. Next, secure the motor unit by tightening right-hand lock nut B. When tightening right-hand lock nut B, hold the two bevelled surfaces of the hub axle (8-mm wide) with a spanner to stop the hub axle from turning. Check that the guide of right-hand lock nut A is seated securely in the guide hole on the front of the motor unit. otor unit guide hole Right-hand lock nut A guide otor unit Front For standard fork end The motor unit may be obstructed by the frame in this case, which can cause difficulties in setting the hub into the fork ends. Turn the motor unit slightly as shown in the illustration before setting the hub into the fork ends. At this time, do not tighten the brake unit fixing nut of the Inter- brake so that the Inter- brake can rotate on the hub axle during installation.
