Watch the movement of the door arm. If the Chamberlain
Door Arm hits the rail before the garage door is fully
open, the angle of the arms must change. Close the
garage door and use another hole to change the angle of
the system. Try again until the Chamberlain Door Arm

operator head is quicker.

ML750, ML850 please read section #15, setting limits
manually as found in the HAVING A PROBLEM section in
your owner’s manual. While setting the door limits manually,
leave door and operator disconnected at all times.
15. Use limit adjustment of
garage door opener to
level the garage door
WARNING
4. Reconnect the inner and outer trolley sections so the door is
connected to the operator.
Do not attempt to adjust the spring. Call a local
garage door installing professional.
5. Force must be learned after completion of the limit settings.
For models ML700, ML750, ML850 please read section #26.
The Protector System™ (a safety reversing sensor
accessory) must be installed, if the Chamberlain
Arm is used (model 770E).
6. Run the operator again to ensure the door is opening and
closing correctly.
Continue with the instructions in your Owner’s Manual.
Having a problem?
1. Pull the manual release handle to disengage the trolley.
2. Lift the door about halfway. Release the door. It should stay in
place, supported entirely by its springs.
3. Raise and lower the door to see if there is any binding or
sticking. If your garage door binds, sticks or is out of balance,
call a professional garage door service engineer.
Note: Lubricate the inside and outside of the rail.
Note: In some cases you may find the door will not open fully
until the force has been set.
Note: In rare installations, the canopy door may touch the
operator rail when closing. This is NOT the fault of the operator
or arm. If this occurs:
1. Manually check the operation of the canopy door to ensure
that it is closing easily. The door must have a slight drop at
the start of closing.
2. If the door is not running easily, check that the side wires are
not catching or binding on the wire guides. Move the guides
until the wires run free.
3. Raise the operator head by about 50mm (2”) vertically so
there is a slight downward angle on the rail.
4. The door spring may be over tensioned.
