Setting up the Motor Bracket

There are 3 drive gears included – 1 for Canon focus ring, 1 for Fujinon focus ring, 1 for iris ring of
either type. You merely need to select the correct black drive gear by checking the teeth against the
lens ring. Based on these factors, attach the appropriate black drive gear to the motor spindle. It may
be a tight fit initially, but once it's started you can use the fixing screw and washer to help press the
gear into place.
The motor bracket should attach to directly to your lens. It comes set
up for standard size lenses. If you have a small-diameter lens for a
1/3" sensor camera, you may have to reverse the attachment arm to
engage on the smaller-radius side. Try mounting the bracket first
and if it engages tightly without moving, you don't need to flip the
bracket. Set the position of the motor-gear relative to the gear ring
on the lens, but leave the gears disengaged for now.
Also note that you can detach the motor from the bracket and flip its
position on the bracket, or simply flip the entire bracket around, if
needed. There are several ways to configure and attach the bracket
system – it was designed to be flexible to work with your needs.
You'll set up the hand unit next. To do this, you need to be able to
rotate the lens by hand and move the motor without moving the lens,
so leave a gap between the motor gear and lens ring for now.
