Please rotate to remove the dust cover of the water inlet, and then add
purified water or distilled water to the water inlet for the engraving
machine. The green range of the water level line is the safe water level,
and then you can fill the water nozzle dust cover, and then turn on the
main power supply and water circulation switch of the machine.
Note: The water level should not be too full, so as not to overflow the
water cooler.
Water inlet
Before starting the laser, be sure to obtain visual confirmation that water
is flowing through the laser tube.
Never let the water in the tank become too hot to cool the laser. Install a
heat alarm or check the water temperature regularly during extended
use. If the water starts to reach 100 ° F (38 ° C), replace it with cooler
water. During this process, either the laser is replaced in phases or the
laser is turned off: never allow the laser to operate without a con stant
flow of cooling water.
