User Manual
An operating coupler should fit in the rearmost hole with
no clearance problems, and the coupler and it’s box can
be attached using screw #212 (supplied, see drawing).
If, however, your choice of coupler does have clearance
problems when mounted in the rear threaded nut, simply
mount it to the threaded nut further forward.
