Recommendation: Clean the water tank and replace the circulating water once a week


Note: Make sure that the laser tube is filled with circulating water before the machine works.


The quality and temperature of the circulating water directly affect the service life of the laser tube. It is recommended to use pure water and control the water temperature below 35°C. If it exceeds 35°C, the circulating water needs to be replaced, or ice cubes are added to the water to reduce the water temperature (it is recommended that the user choose a cooler, or use two water tanks).


Cleaning the water tank: first turn off the power, unplug the water inlet pipe, let the water in the laser tube automatically flow into the water tank, open the water tank, take out the water pump, and remove the dirt on the water pump. Clean the water tank, replace the circulating water, restore the water pump to the water tank, insert the water pipe connecting the water pump into the water inlet, and arrange the joints. Power on the water pump alone and run it for 2-3 minutes (to fill the laser tube with circulating water).


2. Fan cleaning


    If the fan is used for a long time, a lot of solid dust will accumulate in the fan, which will make the fan generate a lot of noise, and is not conducive to exhaust and deodorization. When the suction power of the fan is insufficient and the smoke exhaust is not smooth, first turn off the power, remove the air inlet and outlet ducts on the fan, remove the dust inside, then turn the fan upside down, and pull the fan blades inside until it is clean. , and then install the fan.


Three: Cleaning of the lens (it is recommended to clean before work every day, and the equipment must be turned off)


    There are 3 mirrors and 1 focusing mirror on the engraving machine (the No. 1 mirror is located at the emission exit of the laser tube, which is the upper left corner of the machine, the No. 2 mirror is located at the left end of the beam, and the No. 3 mirror is located at the fixed part of the laser head. The top of the laser head, the focusing mirror is located in the adjustable lens barrel at the lower part of the laser head), and the laser is reflected and focused through these mirrors and emitted from the laser head. The lens is easily stained with dust or other contaminants, causing laser wear or damage to the lens. No. 1 and No. 2 lenses do not need to be removed when cleaning. Edge rotary wipe. The No. 3 lens and the focusing lens need to be taken out from the frame, wiped in the same way, and then put back as they are after wiping.
