38 | 1.<br> |
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 |
44 | applied with the proper orientation.</font></td> |

54 | 2.</strong><br> |
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 |
61 | you have ten thumbs, you might want to ask for help.</font></td> |
