6. Troubleshooting
This section addresses common issues you might encounter with your Soozier Home Gym.
6.1 Assembly Difficulties
If you encounter difficulties during assembly, particularly with aligning components or understanding diagrams:
- Review the assembly manual carefully, comparing both written instructions and illustrations.
- Ensure all fasteners are left slightly loose until the entire frame is assembled. This allows for minor adjustments to achieve proper alignment before final tightening.
- If the machine appears to lean or is unstable after assembly, check that all base components are correctly oriented and tightened evenly. Shimming one side may be necessary if the floor is uneven or if minor manufacturing variations exist.
6.2 Sticking Weight Plates
If weight plates are not moving smoothly or are sticking:
- Ensure the guide rods are clean and free of debris.
- Apply a silicone-based lubricant to the guide rods.
- Check that the selector pin is fully inserted and not bent or damaged.
6.3 Cable or Pulley Issues
If cables are rubbing or pulleys are not rotating freely:
- Inspect cable routing to ensure they are correctly threaded through all pulleys as per the assembly diagram.
- Check pulleys for any obstructions or damage. Ensure they are securely fastened.
- Verify that cables are not frayed or damaged. Replace any damaged cables immediately.
