| Do not release the torsion spring tension |
|
|
| |||
| unless you are a qualified and experienced |
|
|
| |||
| door technician. Instead have a professional | APPROVED WINDING BAR | |||||
| door agency release the tension. | ||||||
| Step 1: Close the door and place vice |
|
|
| |||
| clamps on the back legs of both vertical |
|
|
| |||
| tracks, above the third roller to prevent the |
|
|
| |||
| door from lifting as you unwind the springs. |
|
|
| |||
| Use only approved winding bars available |
|
|
| |||
| from your dealer. Do not use undersized |
|
|
| |||
| steel rods, screw drivers or anything else |
|
|
| |||
| to unwind the springs. Position the ladder |
|
|
| |||
| just off to the side of the winding cone. |
|
|
| |||
| The winding cone should be easy to reach |
|
|
| |||
| without putting your body directly in front |
|
|
| |||
| of it. |
|
|
| |||
|
|
|
|
|
|
|
|
| Step 2: Insert a winding bar into one of the |
|
|
| |||
| holes in the winding cone. Exert upward |
|
|
| |||
| pressure. Using caution, loosen the two |
|
|
| |||
| (2) set screws in the winding cone. Be |
|
|
| |||
| prepared to support the full torsional force |
|
|
| |||
| of the spring when the set screws are | SET SCREWS | |||||
| loosened. |
|
|
| |||
| Step 3: Once set screws are loose, slowly |
|
|
| |||
| and carefully lower the winding rod until it |
|
|
| |||
| rests against the door. Insert other winding |
|
|
| |||
| bar into the upper hole. Push up and |
|
|
| |||
| remove lower bar. Carefully lower upper |
|
|
| |||
| winding bar, 1/4 turns at a time until it rests |
|
|
| |||
| against the door. Repeat process until all |
|
|
| |||
| tension is relieved. If your door is equipped |
|
|
| |||
| with two (2) torsion springs, follow the same |
|
|
| |||
| procedure to relieve tension on the second |
|
|
| |||
| spring. |
|
|
| |||
| Step 4: Remove vice clamps from tracks, |
|
|
| |||
| unbolt torsion shaft assembly and remove |
|
|
| |||
| from work area. |
|
|
