Levorotary/Dextrorotary Distinction:

HELPFUL TRICK: Make an "O" with your index finger and thumb. Using the tip of your finger as the end of the wire, follow the direction down your finger and it will give you the direction the spring is coiled.

Adjust the Spring Tension: It is dangerous to adjust the torsion spring. Please call a professional to adjust.

REMOVING THE OLD SPRINGS
WARNING
It is dangerous to remove the torsion spring. Please call a professional to operate.

- Unplug the garage door opener and clamp the door to the track. Disconnect the garage door opener so the door remains closed. Use locking pliers or a C-clamp to secure the door to the track to keep it from opening when you release the tension on the springs.

- Loosen the set screws while holding each spring with a winding bar. Position a sturdy ladder to the side of the springs, rather than working directly in front of them, for safety reasons. Put on eye protection and leather gloves. Push a winding bar into the bottom hole of the winding cone on the outside of 1 spring. Use a wrench to loosen the 2 set screws. Keep a firm grip on the bar as the spring will expand powerfully as screws are released. Repeat on the other side. To ensure the bars fit securely into the winding cone holes, file down the ends.
Note:
A: Using a screwdriver, pin punch, or plier handles to unwind the bar could result in serious injury, as these tools aren't designed to hold the spring in place.
B: Avoid standing on a bucket or chair to reach the springs. Use a ladder to minimize the risk of injury.

- Unwind each spring with the help of 2 winding bars.
Position the second winding bar into a hole on the winding cone at a perpendicular angle to the first. Unwind the spring 1/4 turn at a time, moving the winding bar to the next open perpendicular position after each 1/4 turn. Repeat on the other spring.

- Remove the nuts and bolts, then slide the springs to the end brackets. Using a wrench, remove the 2 nuts and bolts that secure each spring to the center bracket. Then slide each spring toward the end bracket.

- Secure the tube and remove the springs, cables, and cable drums. Use locking pliers or a C-clamp to secure the torsion tube to the center bracket to keep it from moving. Then, use a wrench to loosen the set screws on both lift cable drums. Disconnect the lift cables, then slide cable drums and springs off the torsion tube.
Note: Securing the tube is an essential step that will prevent the tube from moving around and potentially injuring you, so be sure to fully lock it in place.
WARNING
It is dangerous to install the torsion spring. Please call a professional to operate.

- Slide the left spring onto the tube and add the cable drum.
When your new springs arrive, put the new left spring on the torsion tube, ensuring that the stationary cone on the end of the spring faces the center bracket. After sliding the new spring into place, replace the cable drum and insert the torsion bar into the left bearing bracket.

- Install the center bearing and the right spring, then secure the cones. Slide the torsion bar to the left then add the center bearing. Slide the right spring onto the bar and press the bearing into the stationary cone. Connect both stationary cones to the center bracket with the nuts and bolts you removed previously. Remove the locking pliers or clamp from the center bracket.

- Thread the cables and tighten the drums.
Run the lift cable between the roller and the doorjamb. Slip the lift cable end through the cable slot on the drum. Then attach locking pliers to the torsion tube to secure it in place. Spin the drum to wind the cable into the grooves, then tighten the set screws. Repeat on the other side, leaving the locking pliers in place. Note: For the door to operate properly, you need the same amount of tension on both sides, so take care to tighten each side evenly.

- Wind the springs.
Insert 2 winding bars into the winding cone so they are perpendicular to each other. Use the bars to turn the spring a quarter turn at a time, moving the bars to holes in the cone as necessary. Follow the supplier's recommendation for the number of turns to complete. Repeat on the other spring.
Note:
A: Generally, you'll need 30 quarter-turns for a 7 ft (2.1 m) tall door and 30 quarter-turns for an 8 ft (2.4 m) tall door.
B: Winding the spring too tight could cause it to break and injure you, so it is important to follow the supplier's recommendation and don't over-wind the spring.

- Stretch the springs out 1/4 inch (6.4mm).
When the spring is fully wound, leave 1 winding bar in a slot of the cone perpendicular to the floor. Tap the winding bar with a hammer to stretch the 1/4 inch (6.4mm) out from the center. Repeat on the other side.

- Tighten the set screws.
Tighten each set screw until it contacts the torsion tube. Tightening the screw more than this could distort or puncture the torsion tube, so be sure to make no more than 1 full rotation once the screws touch the torsion tube.

- Remove the clamps or pliers.
It is now safe to remove the clamps or pliers you used to hold both torsion bar and the garage door itself in place.
Note: When to add or unwind 1 or 2 quarter turns, must hold clamps or pliers again.

- Check the balance after installation.
Leave the door at half way position:
If the door moves up on itself, means torsion springs are wound too much. In this case, unwind both of the torsion springs 1 or 2 quarter turns so the door balances itself.
MAINTENANCE
- Use a neutral cleaner and a soft brush to clean the garage door times a year.
- Use a lightweight oil spray on all springs, hinges, rollers and pivot points at least once a year to allow your garage door to slide smoothly up and down.
- Once a year, you should thoroughly inspect the electric garage door and tighten all screws, nuts or bolts that may be loose.
- Using a cloth and a concentrated but non-corrosive cleaner, wipe the garage door track and carefully clean all exposed parts of the rollers to remove all excess moisture.
