5. Maintenance
5.1 Cleaning
To maintain optimal performance and appearance:
- Clean the flashlight body with a soft, damp cloth. Avoid harsh chemicals or abrasive materials.
- For the lens, use a clean, soft cloth specifically designed for optical surfaces.
5.2 O-ring Replacement
The PL01's IP68 waterproof rating relies on properly sealed O-rings. Periodically inspect them for any signs of wear, cracks, or damage.
- If O-rings appear damaged, replace them with the provided spare O-rings.
- Apply a thin layer of silicone grease to the O-rings to ensure a better seal and prevent drying.
5.3 Battery Care
- If the flashlight will not be used for an extended period, remove the batteries to prevent potential leakage and damage.
- For the rechargeable battery, recharge it every 3-6 months to maintain its overall lifespan and capacity.

6. Troubleshooting
If you encounter issues with your WUBEN PL01, please refer to the following common problems and solutions:
- Light does not turn on:
- Ensure the batteries are installed with correct polarity.

- Light flickers or dims unexpectedly:
- The battery level may be low. Recharge the included battery or replace AAA batteries.
- Ensure the tail cap is securely tightened.
- Clean battery contacts and internal contact points.
- Water ingress (if exposed to water):
- Immediately turn off the flashlight and remove the batteries.
- Inspect the O-rings for any damage, tears, or improper seating. Replace if necessary.
- Ensure the tail cap was fully tightened before exposure to water.
- Allow the flashlight to dry completely before reassembling and attempting to use it.
If the problem persists after attempting these solutions, please contact WUBEN customer support.
