Maintenance

To ensure optimal performance and longevity of your Feyachi WL25 Tactical Rifle Light, follow these maintenance guidelines:

  • Cleaning: Regularly wipe the flashlight body with a soft, damp cloth. Keep the lens clean and free of dirt or debris. Do not use abrasive cleaners.
  • Battery Care: Recharge the battery using the provided charger when the light output diminishes. Store the battery in a cool, dry place when not in use for extended periods.
  • O-Rings: Periodically inspect the O-rings for wear and tear. Replace them if damaged to maintain the IPX5 water-resistant rating. Apply a thin layer of silicone grease to the O-rings to ensure a good seal.
  • Storage: Store the flashlight in a dry environment, away from extreme temperatures and direct sunlight. Remove the battery if storing for several months to prevent potential leakage.
