Instrukcje instalacji
Safety Warning: Garage door springs are under extreme tension and can cause serious injury. If you are unsure about any step, consult a qualified garage door technician. Do not attempt to remove the bottom roller bracket if it is connected to the lift cable, as it is under spring tension.
- Przygotuj drzwi: Close the garage door completely and disengage the garage door opener. This prevents the door from opening unexpectedly during installation. All rollers will be replaced with the door in the closed position.
- Remove Existing Rollers (Upper and Middle): For rollers not connected to the lift cable, carefully pull the roller off its track. Use a claw hammer or pry bar if necessary to gently pry the roller out of the track. Once off the track, remove the roller from its hinge bracket.
- Install New Rollers (Upper and Middle): Insert a new DURA-LIFT roller into the hinge bracket. Repeat this process for all upper and middle rollers, working on one side of the garage door at a time.
- Track Removal (Optional): If you find it difficult to remove rollers from the track, you may carefully unbolt sections of the track to create more access. Ensure to re-bolt the track securely in place once all new rollers are installed.
- Replace Top Rollers: To replace the top rollers, the door should be closed. Remove the bracket that holds the roller and replace it with a new roller. Reattach the bracket and repeat the process on the other side of the door.
- Bottom Roller Replacement (Caution): The bottom roller is typically integrated with the lift cable and is under significant spring tension. It is recommended to consult a professional for this step or proceed with extreme caution. If replacing yourself, ensure the door is fully open and supported, and the tension on the cable is relieved before attempting to remove the bottom roller.
- Ponowne zaangażowanie otwieracza: Once all rollers are replaced and securely in place, re-engage the garage door opener and test your door to ensure it opens and closes smoothly and quietly.

Konserwacja
To ensure the continued smooth and quiet operation of your DURA-LIFT garage door rollers, periodic maintenance is recommended:
- Smarowanie: Apply a silicone-based garage door lubricant to the roller stems and the inside of the tracks annually. Avoid using WD-40 as it is a degreaser and can remove existing lubrication. The built-in lubrication groove on the rollers helps distribute lubricant effectively.
- Czyszczenie: Periodically inspect the rollers and tracks for any accumulation of dirt, dust, or debris. Clean as needed to prevent interference with roller movement.
- Kontrola: Regularly check rollers for any signs of wear, damage, or wobbling. While DURA-LIFT rollers are designed for durability, timely inspection can prevent potential issues.
Rozwiązywanie problemów
If you experience issues after installing your new rollers, consider the following:
- Persistent Noise: While nylon rollers significantly reduce noise, other components of your garage door system (e.g., opener, springs, hinges) may still contribute to sound. Ensure all other moving parts are properly lubricated and in good condition.
- Rough Operation: Verify that all rollers are correctly seated in their tracks and that the tracks themselves are clean, free of obstructions, and properly aligned. Check that all hinge bolts are tightened.
- Roller Wobble: Ensure rollers are fully inserted into their hinge brackets and secured.
