It is 100% your responsibility to operate the machine in a safe manner. Thunder Laser USA assumes no responsibility for any damage, harm, injury etc. that may result from the bypassing of the machine safety. You should wear the proper PPE like safety glasses, inform anyone in the immediate area and take all the proper precautions to protect yourself and others from injury.
