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. |
9Fasten Rail to Opener and Install
Chain/Belt
Holding chain (4) and belt (5) out of the way, slide rail
(1)onto shim (2) until rail is secure. Take the chain/belt and wrap it around the sprocket (3). Make
sure the teeth on the sprocket have engaged the chain/belt.
3. | Depending on your door's construction, you might need a special door arm. See your dealer. |
4. | Do you have an access door in addition to the garage door? If not, Model 1702E Outside Quick Release |
| Accessory is required. This accessory allows manual operation of the garage door from outside in case of |
| power failure. |

ASSEMBLY SECTION
IMPORTANT: If you have a canopy door, you need to use the instructions packed with The Chamberlain Arm™ Accessory in conjunction with this Owner's Manual when assembling the rail.
Thread spring nut on carriage bolt until finger tight. Insert a screwdriver tip (1) into one of the slots of the nut ring (2) and brace it firmly against the header sleeve. Place an open end wrench (3) on the square end of the spring nut (4), slightly rotate nut about 1/4
5Assemble the Rail
Grease inside edges of rail sections using grease (1). Place rail pieces (2) on flat surface for assembly. All four rail sections are interchangeable. Slide rail brace
(3)onto rail section. Connect rail by sliding rail brace onto next rail section. Tap rail assembly (4) on piece of wood (5) until rail sections are flush. Repeat with remaining rail sections.
turn clockwise until nut ring (2) is released against header sleeve (5). This sets spring to optimum chain tension. Chain may slip off sprocket if chain/belt is too
loose. If chain does slip re-tighten spring nut by turing nut clockwise 1/2 turn. Do NOT overtighten chain/belt.
12Position the Header Bracket
6Install the Chain/Belt
Remove chain/belt from carton and lay chain out on floor (do not allow chain/belt to twist).
A. Chain: Push pins of master link bar (3) through chain link (4) and hole in back end of trolley (5). Push cap (2) over pins and onto notches. Slide clip-on spring (1) over cap and onto pin notches until both pins are securely locked in place.
B. Belt: Hook the trolley connector (6) into the slot (7) on the trolley (8).
The header bracket must be rigidly fastened to a | 1 |
structural support of the garage. Reinforce the wall or | |
ceiling with a 40mm (1-1/2") board if necessary. | 4 |
Failure to comply may result in improper operation of |
safety reverse system. | 2 |
You can attach the header bracket either to the header |
wall (1) or to the ceiling (3). Follow the instructions which | |
will work best for your particular requirements. With the | |
door closed, mark the vertical centerline (2) of the garage | 3 |
door. Extend line onto header wall above the door. | |
Open door to highest point of travel. Draw an intersecting | |

13Install the Header Bracket
NOTE: Refer to vertical center and horizontal lines created in step 12 for proper placement of header bracket.
A. Wall Mount: Center the header bracket (1) on the vertical center line (2) with the bottom edge of the header bracket on the horizontal line (4) (with the arrow pointing toward the ceiling). Mark all of the header bracket holes (5). Drill 4,5mm (3/16") pilot holes and fasten the header bracket with wood screws (3).
