Maintenance
- Cleaning: Disconnect the power before cleaning. Wipe the light with a soft, damp cloth. Do not use abrasive cleaners or solvents, as they may damage the surface.
- Storage: When not in use, store the work light in a cool, dry place, away from direct sunlight and extreme temperatures. The fold-flat design allows for compact storage.
- Cord Inspection: Regularly inspect the power cord and plug for any signs of damage, fraying, or exposed wires. If damage is found, discontinue use immediately and seek professional repair or replacement.
- Weather Protection: While the light is IP66 weatherproof, prolonged exposure to harsh conditions (e.g., submersion in water) should be avoided to ensure longevity.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on. | No power supply. Faulty power outlet. Damaged power cord/plug. | Ensure the power cord is securely plugged into a working outlet. Test the outlet with another device. Inspect the cord and plug for damage. Do not use if damaged. |
| Light flickers or dims unexpectedly. | Unstable power supply. Loose connection. Overheating (unlikely for LED, but possible in extreme conditions). | Ensure a stable power source. Check all connections. If issues persist, discontinue use and contact support. |
| Brightness modes are not cycling correctly. | Switch malfunction. | Ensure you are pressing the switch firmly. If the issue persists, contact customer support. |
| Magnetic base is not holding securely. | Surface is not ferromagnetic. Surface is too thin or uneven. Excessive weight/vibration. | Ensure the surface is made of a magnetic material (e.g., steel, iron). Attach to a flat, clean, and sufficiently thick metal surface.
