2. Setup
The Stair Climber Trolley Dolly requires minimal assembly. Follow these steps to prepare your dolly for use:
- Unfold the Frame: Gently pull the handle upwards and unfold the main frame until it locks into place. Ensure all joints are securely extended.
- Attach the Bag (if separate): If your model includes a removable bag, slide it onto the frame, ensuring it is properly seated and secured.
- Check Wheel Security: Verify that all six wheels are firmly attached and rotate freely. Some users have noted that wheels may require a firm push until a "click" is heard to ensure they are fully engaged.

5. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Dolly is difficult to pull up stairs. | Overloaded, wheels obstructed, or improper technique. | Reduce load. Check wheels for debris. Ensure the dolly is tilted correctly to engage the stair-climbing wheels. |
| Wheels feel loose or detached. | Wheels not fully engaged during assembly. | Push wheels firmly onto axles until a "click" is heard, indicating secure attachment. |
| Dolly makes loud noises when climbing stairs. | Normal operation on some surfaces, or wheels may need lubrication. | This can be normal. If excessive, check for debris in wheels or apply a small amount of silicone lubricant to wheel axles. |
| Dolly rolls away when loading/unloading. | No wheel lock mechanism on this model. | Exercise caution. Position the dolly against a wall or use your foot to stabilize it during loading and unloading. |
