Installation precautions and common problem solving:
1: The wind fire wheel uses three AG10 batteries (self-contained). Please correctly align the positive and negative poles during installation. The wordless end faces the spring
2: Be sure to put the battery in the black insulating leather case, and do not expose it, otherwise the metal short circuit between the battery and the lamp housing will cause the battery to discharge and heat, and the battery will run out of power in a few minutes.
3: Be careful when screwing the lamp cap, and make sure that the metal strip in the notch beside the lamp cap contacts the metal base well (if the metal is too close to the inside, you can manually pull it out a little, but you must be light!)
4: If the wheel does not light up under normal conditions, you can adjust the length of the spring to ensure full contact with the battery (do not use too much force to easily cause the spring to fall off), or you can operate step 3
