5.2 Detachable Preacher Pad
The preacher pad can be detached for specific exercises, such as leg curls, to improve training efficiency. To detach, locate the quick-release mechanism or pin securing the preacher pad and remove it. Reattach by aligning and securing the pad until the mechanism locks.
5.3 Leg Developer Usage
The leg developer features a 2-in-1 weight rod compatible with both Olympic and standard weight plates. To use, slide your desired weight plates onto the rod. The leg developer also includes a fixed pin to lock it in position when not in use or for specific exercises like sit-ups without weights. To unlock the sleeve for weight plates, you may need to unscrew a retaining screw first.

6. Maintenance
Regular maintenance ensures the longevity and safe operation of your weight bench.
- Cleaning: The premium leather material is sweat-resistant and durable. Wipe down the pads with a damp cloth after each use to remove sweat and dirt. Use a mild soap solution for deeper cleaning, then wipe dry. Avoid abrasive cleaners.
- Inspection: Periodically check all bolts, nuts, and pins for tightness. Retighten as necessary. Inspect the frame for any cracks or damage, and the upholstery for tears or excessive wear.
- Storage: Store the bench in a dry, clean environment away from direct sunlight and extreme temperatures.
7. Troubleshooting
If you encounter any issues with your OPPSDECOR Adjustable Weight Bench, refer to the following common solutions:
- Bench feels unstable: Ensure all assembly bolts are fully tightened. Check that the bench is on a level surface; use the adjustable base feature to compensate for uneven floors.
- Adjustment pin not locking: Ensure the backrest or seat is properly aligned with the desired hole. Clean any debris from the pin mechanism.
- Squeaking noises: Check and tighten all bolts. Applying a small amount of silicone-based lubricant to pivot points may help, but avoid getting lubricant on upholstery.
- Difficulty moving the bench: Ensure the wheels are clear of obstructions. Lift the non-wheeled end sufficiently to allow the wheels to roll freely.
If problems persist, please contact customer support.
