Installation Instructions
Top Channel Installation (Cont)
3.
With the help of two assistants, lift the top channel
up and over roto, yoke and OV (Figure 19).
DANGER
Be sure that the feeder wire and/or any access
control pad wiring is out of the way and is not
caught between the top channel and the yoke,
roto or OV, as this may damage the wires.
4.
Align the top channel spline shaft with the roto
cavity and carefully lower the top channel spline
shaft into the roto cavity (Figure 20).
NOTE
Apply grease to the end of the spline shaft before
inserting.
5.
Once the top channel is seated firmly in place, use
an Allen wrench to tighten the set screw
(Figure 20).
6.
Confirm roto is level and plumb.
