4. Mounting Header Bracket

 Determine the highest arcing point of the garage door (Fig.4) and mark this as a horizontal line on the

structural wall (header) above the top edge of the garage door. (Fig.5)

 Determine the Garage door Center Line and mark a vertical line on the Header above the top edge of the

Garage door. (Fig.5)

 Centralize the bottom edge of the Header Bracket on the intersection of the 2 marked lines and mark the

location of at least 2 of the Header Bracket screw holes (Fig.5) The 2 holes must both be either in the

vertical or horizontal plane. (not one vertical and the other horizontal)

 Drill the 2 screw holes and use 2 screws of at least 8mm diameter to secure the Header Bracket to the

header.

 Important Note: The Header Bracket carries ALL of the opening and closing thrust of the AGDO

and as such must be securely fastened to a rigid, structural member of the garage.

5. Mounting Towing Bracket

 Determine the Garage Door Center Line and affix the Towing Bracket (Fig.5) to a structural member of

the garage door. Mark the location of at least 2 screw holes as far apart from each other as possible

 Drill the 2 screw holes with appropriate drill and securely mount the Towing Bracket to the garage door

using screws of at least 6mm diameter.

 Important Notes:

a. It is recommended to use fixing screws and nuts rather than self drilling screws.

b. For Sectional Garage Doors the pivot point of the Towing Bracket, where it attaches to the

Towing Arms, should be located approx 150 ~ 200mm down from the top edge of the top

panel. For Tilt Doors the pivot point should be as close to the top edge of the Garage door as

possible.

6. Attaching Drive Pole Assembly to Header Bracket

 Lay the assembled AGDO on the garage floor in line with the centerline of the garage door so that the

Power Head (Fig.2) is furthest from the garage door.

 Important Note: avoid scratches and potential damage to the AGDO plastic covers by placing the

Power Head on cardboard or foam.

 Lift the Drive Pole Assembly up to the Header Bracket so that the Terminal Bracket sits in between the

ears of the Header Bracket. (Fig 6)

 Align the mounting holes of the Header Bracket and Terminal Bracket and fully insert the Clevis Pin.

 Secure the Clevis Pin with the Spring Pin.
