ASSEMBLY STEP 1

Attach the Collar to the Motor Unit

To avoid installation difficulties, do not run the door operator until
instructed to do so.
• Loosen the collar screws (1).
• Attach collar to either the left or the right side of the motor unit.
Ensure that the collar is seated all the way on motor shaft until stop is
reached.
• Position the collar so that the screws are facing up (accessible when
attached to the torsion bar).
• Tighten both sides of collar screws equally to secure collar to the
motor unit (16Nm-19Nm . of torque).
Use Hex bits 1/8" from hardwarebag..
NOTE: For most installations the screws should be facing up for easy
access. Do not tighten set screws until indicated.
ASSEMBLY STEP 2
Attach Mounting Bracket to Motor Unit
• Loosely attach slotted side of mounting bracket to the same side of
the motor unit as the collar, using self-threading screws provided.
NOTE: Do not tighten until instructed. Illustrations shown are for left side
installation.

the case where the torsion bar is not round or the normal mounting area
is obstructed.
To prevent possible SERIOUS INJURY or DEATH, the collar MUST
be properly tightened. The door may not reverse correctly or limits
