(1) If there is no current: check whether the laser power is connected, whether the high voltage wire is loose or off, and whether the signal wire is loose;

(2) If there is current: check whether the lens is broken, whether the laser tube light hole and lens are polluted, and whether the light path is seriously deviated.

2. Check whether the water circulation system is normal

(1) No water: check whether the water pump is damaged or not powered on;

(2) Water supply: check whether the water inlet and outlet are connected reversely or the water pipe is broken.
