39 - </strong>If you going to solder to the motor tabs, it's a good idea to
40 - bend them out of the way before installing the encoder. If you're going to
41 - use push on connectors this step isn't necessary. Be sure to orient the
42 - motor as shown EXACTLY as the raised plastic (name, logo and plus sign)

55 - Before removing the adhesive backing material, fit the sensor to the motor
56 - as shown. It has to be oriented EXACTLY as shown for proper fit. When you
57 - are happy with the placement, remove the backing and carefully press it in
58 - place. I have not needed the expensive alignment tool from US Digital to
59 - do this, but you have to be careful not to press it firmly until it is
60 - exactly centered. If you are good with your hands this will be easy. If
