Keep the water-proof rings lubricated. Vaseline and silicone oil are preferred, and little used will work. When you screw the middle pipe or the tail pipe and feel it tough, it is a sign for lubrication.

Caution: if water-proof rings are not lubricative, they won’t perform well, and lubrication must be done timely.

Four extra water-proof rings are provided among the spare parts for future replacement. Unload batteries if the torch remains unused for a long time.

If the optical lenses are stained with dust or dirt, please try blowing dust or dirt away. If some dust or dirt still stays after the blowing, then clean the lenses with lens tissue or chamois leathers.
