BEFORE YOU BEGIN

1. Look at the wall or ceiling above the garage door. The header bracket must be securely fastened to structural
supports.
2. Do you have a finished ceiling in your garage? If so, a support bracket and additional fastening hardware
(not supplied) may be required.
3. Do you have an access door in addition to the garage door? If not, model CM1702 outside quick release accessory
is required. This accessory allows manual operation of the garage door from outside in case of power failure.
4. Complete the following test to make sure your garage door is balanced and is not sticking or binding:
• Lift the door about halfway. Release the door. If balanced, it should stay in place, supported entirely by its springs.
• Raise and lower the door to see if there is any binding or sticking. If your door binds, sticks, or is out of balance, call
a trained door technician.

ASSEMBLE 7527SP1 POLE PACK (OPTIONAL)
Remove the 5 sectional poles from the carton and lay them
out on the floor. The end pole (i.e. the pole without a
tapered edge) should be placed at the header end.
Assemble the poles by inserting the tapered end into the
non-tapered end of the next pole as illustrated. Ensure that
each pole is pushed firmly into the next.
NOTE: If using a mallet to drive the joins home, use a
piece of timber at each end to minimise burring.
