4.3 Folding and Storage
The JOROTO MD55 bench is designed for compact storage. To fold the bench:
- Ensure all attachments (preacher curl pad, leg extension) are in their most compact or removed positions.
- Locate the folding mechanisms, typically pins or levers, on the main frame.
- Release the mechanisms and carefully fold the bench sections together.
- Secure the folded sections if there are locking pins or straps.
Once folded, the bench can be easily stored under a bed or in a wardrobe, making it ideal for small living spaces.
5. Maintenance
- Cleaning: Wipe down the bench with a damp cloth after each use to remove sweat and dirt. Use a mild soap solution for deeper cleaning, then wipe dry.
- Inspection: Regularly check all bolts, nuts, and moving parts for tightness and wear. Tighten any loose fasteners.
- Lubrication: Apply a small amount of silicone-based lubricant to moving parts and adjustment pins periodically to ensure smooth operation.
- Storage: Store the bench in a dry environment, away from direct sunlight and extreme temperatures, to prolong its lifespan.

6. Troubleshooting
- Bench feels unstable: Ensure the bench is on a flat surface. Check all assembly bolts and nuts for tightness. Verify that the adjustable non-slip stabilizer pads are properly adjusted and making full contact with the floor.
- Difficulty adjusting positions: Check if adjustment pins are fully retracted before attempting to move sections. Apply a small amount of lubricant to the pins and moving joints if they are stiff. Ensure no debris is obstructing the adjustment holes.
- Squeaking noises: Identify the source of the noise. Often, it can be resolved by tightening loose bolts or applying lubricant to pivot points.
- Leg extension not holding weight plates: Ensure the weight storage post is securely attached and that the plates used are compatible with the 1-inch diameter post.
