If the arrowhead and hole are not aligned, rotate the hub key
clockwise using any appropriate tool to achieve alignment.
Figure 19. Step 5.
Step 6:
With the arrowhead and hole aligned, push on the two captive
mounting screws until they are nearly flush with their mounting collars.
This will simplify the Step 7 mounting process.
Section 7: Installation of Motor Operator
Proceed with the following 11 steps:
Step 1:
Remove the four screws holding the front cover in place (two
on each side of the cover).
Figure 16. Step 1.
Step 2:
Remove the front cover. Pull down on the charging handle to
simplify removal.
Figure 17. Step 2.
Step 3:
If an existing motor operator is already installed, remove it first
by following the instructions outlined in Section 8. If not, proceed with
Step 4.
Step 4:
To simplify installation, examine the motor operator to verify
that the hub key on the motor operator is in the proper position. It is
properly positioned if the arrowhead on the hub key lines up with the
hole in the hub housing as shown. If they are aligned, proceed to
Step 6.
