Reinforced arm for tilting garage door

Plan:

• 2 people + protections
• 1 clamp
• 1 screwdriver with a size 10 bit
• 1 large flat screwdriver
• 1 wedge
• 1 new arm + perforated strap - door in manual mode (motor carriage disengaged)

Procedure:

1 - Open the door and secure it with a clamp in the rail, in front of a roller

(No intervention if the door is closed and springs are taut!!!)

2 - Detach the springs one by one on the side of the arm to be changed and remove the perforated strap from the arm

3 - Using a screwdriver equipped with a size 10 bit, remove the 2 upper screws that hold the arm to its pivot

4 - Support the bottom of the door with a second person

5 - Remove the clamp that blocks the roller

6 - Close the door gently with two people, one inside and the other outside

!! CAUTION DELICATE MANEUVER !!

Be careful because there are no more springs, the weight of the door may be surprising!

Be careful if the door has no handle, the maneuver will be done from the bottom of the frame, so watch out for pinching risks during the maneuver and at the end of closing.

7 - Once the door is closed, secure it with a clamp in the rail, in front of a roller

8 - Place a small wedge under the door frame, of the same height as the space between the floor and the frame

9 - Remove the clip at the end of the arm (attached to the connecting piece at the bottom of the apron) using a large flat screwdriver

10 - Using a screwdriver equipped with a size 10 bit, remove the 2 lower screws that hold the arm to its pivot
