Noise is heard from the laser head or exhaust fan

If the fan improves after a few minutes of running

The bearing oil may solidify due to a drop in temperature, causing an abnormal noise. If the temperature rises and the oil becomes softer, the abnormal noise will disappear.

If the abnormal noise does not disappear after operating for a few minutes

Please check the following points.

Foreign matter

If foreign matter that interferes with the rotation of the fan is detected, clean it with a compressed air duster or a soft cloth.

The fan axis is slanted

The fan shaft may tilt due to some external force, which may cause it to come into contact with the rotation of the motor. If a tilt is detected, please contact us.
