Initial Operation:The Chamberlain Arm has been designed so that, when usedwith a Chamberlain manufactured operator, the door will open toa fully horizontal position (Figure 16).Note: The door may be designed in such a way that it does notopen to the full horizontal. Adjust the UP limit so that the doorstops at a slightly downward angle when open.Note: If safety reversing sensors (Protector System) must beinstalled, please refer to your owner´s manual beforeproceeding to Setting the limits and learning the force:Setting the limits and learning the force:When returning to your Owner’s Manual, adjust the trolley travellimits as follows:1. With the inner and outer trolley sections still disconnected,manually open your door to the horizontal position. Make amark on the rail where the end of trolley nearest to theoperator stops.2. Manually close the door and mark the rail where the end ofthe trolley nearest the door stops.3. With the inner and outer trolley sections still disconnected,activate the operator and adjust the limits following theowners manual of the garage door opener, until the innertrolley stops on the marks you made. For models ML700,ML750, ML850 please read section #15, setting limitsmanually as found in the HAVING A PROBLEM section inyour owner’s manual. While setting the door limits manually,leave door and operator disconnected at all times.4. Reconnect the inner and outer trolley sections so the door isconnected to the operator.5.

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 fullyuntil the force has been set.Note: In rare installations, the canopy door may touch theoperator rail when closing. This is NOT the fault of the operatoror arm. If this occurs:1. Manually check the operation of the canopy door to ensurethat it is closing easily. The door must have a slight drop atthe start of closing.2. If the door is not running easily, check that the side wires arenot catching or binding on the wire guides. Move the guidesuntil the wires run free.3. Raise the operator head by about 50mm (2”) vertically sothere is a slight downward angle on the rail.4. The door spring may be over tensioned.15141.
