Installation Guide
Installing your new torsion springs requires caution and precision. Follow these steps for a safe setup (professional installation recommended):
- Prepare Tools: Gather a socket wrench, vise grips, winding bars (included), ladder, and safety glasses.
- Release Tension: Safely unwind the old springs by inserting the winding bars into the winding cone and slowly releasing tension.
- Remove Old Springs: Loosen the set screws on the winding and stationary cones, then slide the old springs off the torsion bar.
- Install New Springs: Slide the new left and right springs onto the torsion bar, ensuring correct orientation (left and right labeled).
- Secure Cones: Tighten the set screws on the winding and stationary cones to secure the springs to the bar.
- Wind Springs: Use the 17.2-inch non-slip winding bars to apply the recommended number of turns (typically 7-8 full turns for a 7-8ft door).
- Test Operation: Carefully lift the door to check balance and adjust tension if needed.
- Lubricate: Apply a light garage door lubricant to the springs for smooth operation (though coating minimizes lubrication needs).
Safety Warning: Torsion springs are under high tension and can cause serious injury. If unsure, hire a professional technician.
