SITE PREPARATIONS
It is imperative that the wall or mounting surface provide adequate support for the operator.
This surface must:
a) Be rigid to prevent play between operator and
door shaft.
b) Provide a level base.
c) Permit the operator to be fastened securely and
with the drive shaft parallel to the door shaft.
The safety and wear of the operator will be adversely
affected if any of the above requirements are not met.
KEEP DOOR BALANCED. STICKING OR BINDING
DOORS MUST BE REPAIRED. DOORS, DOOR
SPRINGS, CABLES, PULLEYS, BRACKETS AND
THEIR HARDWARE MAY BE UNDER EXTREME TENSION AND CAN CAUSE SERIOUS PERSONAL
INJURY. CALL A PROFESSIONAL DOOR SERVICEMAN TO MOVE OR ADJUST DOOR SPRINGS OR
HARDWARE.
For metal buildings, fasten 2 x 2 x 3/16 (or larger)
angle iron frames to the building purlins. Retain 51/2 between frames. See Figure 1.
