* Please check below photos on how to attach the motor to a William Optics GT71 or a W.O. with a similar focuser
- Remove the brake thumbscrew pointed with red arrow
- Remove the coarse knob
- Align the bracket (place the 6th slot of the bracket on top of the brake hole) and use a bolt and a spacer to secure it in place (you will find different sizes of bolts/spacers in the box)
- Use the appropriate motor coupler from the 6 x motor coupler bag and connect motor shaft with focuser’s shaft. Make sure to tighten all coupler grub-screws.
