6. Troubleshooting
If you encounter any issues with your weight bench, refer to the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Bench feels unstable or wobbly. | Loose fasteners or uneven floor. | Tighten all nuts and bolts. Adjust the rotating base on the feet to level the bench on uneven surfaces. |
| Limited range of motion during leg extensions/curls or preacher curls. | Preacher pad or other padded bars obstructing movement. | Ensure the preacher pad is detached when performing leg exercises. For leg extensions, adjust the seat angle to a higher notch if needed to achieve full range of motion. |
| Difficulty adjusting angles. | Adjustment pins not fully disengaged or engaged. | Ensure adjustment pins are fully pulled out before attempting to change angles, and fully inserted to lock the desired position. |
If the issue persists, please contact customer support.
