Mount the MC-SCR MotoR

The MC-SCR motor can be mounted either to the top
or bottom of the table with lag screws. First, mark the
proper position for the motor's bracket. Use
guide for the positioning of the mounting holes (accurate
for Sailrite 111 sewing machines). If necessary, install the
drive belt first to help ensure proper motor position.
