Initial Operation:
The Chamberlain Arm™ has been designed so that, when used with a Chamberlain manufactured operator, the door will open to a fully horizontal position (Figure 16).
Note: The door may be designed in such a way that it does not open to the full horizontal. Adjust the UP limit so that the door stops at a slightly downward angle when open.
Note: If safety reversing sensors (Protector System) must be installed, please refer to your owner´s manual before proceeding to Setting the limits and learning the force:

When returning to your Owner’s Manual, adjust the trolley travel limits as follows:
1. | With the inner and outer trolley sections still disconnected, |
| manually open your door to the horizontal position. Make a |
| mark on the rail where the end of trolley nearest to the |
| operator stops. |
2. | Manually close the door and mark the rail where the end of |
| the trolley nearest the door stops. |
3. | With the inner and outer trolley sections still disconnected, |
| activate the operator and adjust the limits following the |
| owners manual of the garage door opener, until the inner |
| trolley stops on the marks you made. For models ML700, |
| 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, |

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.
WARNING
Do not attempt to adjust the spring. Call a local garage door installing professional.
The Protector System™ (a safety reversing sensor accessory) must be installed, if the Chamberlain Arm is used (model 770E).
