You may find it helpful to refer to the applicable
illustration as you proceed with the installation of your
garage door operator and The Chamberlain Arm™. The
garage door opener must be installed parallel to the floor.

Follow rail assembly instructions as shown in the Owner's
manual. Note: For the best operating result of canopy doors,
use only 3-sections of the 4-piece rail or add a rail support
bracket as shown (16). Make sure rail support bracket does
not interfere with the trolley movement (Purchase part no.

600121). If 3 rails sections are used, the chain (belt) must be
cut by the same amount. For belts, a new belt clip is
recommended (Purchase part no. 041B5669).

facing lintel, which does not allow the header bracket to
be fitted directly above the garage door, you should see
Figure 16 & text with this instruction.

high point of door travel as shown in the Owner’s
manual.

Standard canopy garage doors

Canopy doors are normally provided without a frame, for
fixing to a timber frame. In this case, ensure header
bracket is located as shown below:

The template is provided for use with two different types
of doors. Position and mark holes as directed below,
based on your requirements.

• Position the template horizontally to match up the
centerlines of the header bracket and the template.
Refer to Figure 8 or Figure 9, depending on your door
style.

• To check, place the extension arm on the trolley into
the slot on the template. The extension arm should be
straight and in line with the garage door operator rail.

• Bend back tabs on the template (Figure 7).

• Rest the bottom of the tabs on the top of the door as
shown in Figure 8 (door without a lip). This provides
proper vertical replacement of holes.

Note: The door arm should extend about 13mm (1/2”)
over the top of the door (Figure 10 or Figure 11). If
not, check template and hole positions.

• Select and mark the (2) template holes which will allow
the mounting screws the best possible support in the
door, (preferable hole locations into the door’s main
bracing) as shown in Figures 10/11.

If possible, use

additional screws.

The garage door may require additional bracing to
provide suitable support.

To prevent damage to garage door, do NOT drill through the
entire door.

• With a 4.5mm (3/16") bit, drill two holes, 25mm (1")
deep.

• Attach the door arm with proper hardware provided
(Figure 12).

Note: Whenever possible, use the nuts and bolts
supplied (A).

For metal or metal-braced doors, use self-tapping
screws supplied (B). For timber or timber-braced doors,
use wood screws supplied (C).

• Before tightening the screws, align the door arm so it
is vertical. Use a level to assist. The tighten the screws.

allow the screws to go into a cross bracing support of
the door (Figure 13). Door may REQUIRE
ADDITIONAL bracing to provide suitable support.

2. Mark and drill two 4.5mm (3/16") holes. Use the proper
screws provided.

The centerline of the garage door opener and the
centerline of the door arm should match to prevent
binding of the arm in operation.

3. Recheck and if not aligned, correct.

Open the garage door slowly and carefully by hand.
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
does not hit the rail anymore. In some cases raising the
operator head is quicker.

WWARNARNINGING

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:

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,
leave door and operator disconnected at all times.

4. Reconnect the inner and outer trolley sections so the door is
connected to the operator.

5. Force must be learned after completion of the limit settings.
For models ML700, ML750, ML850 please read section #26.

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:

Manually check the operation of the canopy door to ensure

1.
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.
