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)
43 + will prevent the adhesive from making good contact if the encoder is not

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
