The bench offers multiple adjustable positions to target different muscle groups. To adjust, locate the adjustment pins or levers beneath the backrest and seat. Pull the pin, adjust the bench to the desired angle (incline, flat, or decline), and ensure the pin locks securely into place before use.

4.3 Using the High Pulley for Lat Pull-Down:
Attach a suitable weight plate (28mm diameter) to the weight post on the high pulley system. Sit on the bench facing the pulley, grasp the lat bar, and perform controlled pull-down movements. Ensure the cable system is free of obstructions and operates smoothly.

The weight posts on the lat pull-down and leg developer are designed to fit standard 28mm diameter weight plates.
5. Maintenance
- Cleaning: Wipe down the bench and frame with a damp cloth after each use to remove sweat and dust. Avoid abrasive cleaners.
- Hardware Check: Periodically check all bolts, nuts, and screws for tightness. Retighten as necessary to ensure stability and safety.
- Foam Padding: Inspect foam padding for tears or excessive wear. Clean with a mild soap solution if needed.
- Cable System (Lat Pull-Down): Regularly inspect the cable for fraying or damage. Ensure pulleys move freely and are lubricated if necessary.
- Storage: The bench is foldable for compact storage. Ensure it is folded correctly and stored in a dry, safe place when not in use.
