Safety rules for laser lights  
General safety instructions  
The laser light/laser radiation used in the GMC Redeye®  
system is Class 2 with maximum 1mW and 650nm  
wavelengths. These lasers do not normally present an  
optical hazard, although staring at the beam may cause  
flash blindness.  
To use this tool properly, you must observe the safety  
regulations, the assembly instructions and the operating  
instructions to be found in this Manual. All persons who use  
and service the machine have to be acquainted with this  
Manual and must be informed about its potential hazards.  
Children and infirm people must not use this tool. Children  
should be supervised at all times if they are in the area in which  
the tool is being used. It is also imperative that you observe the  
accident prevention regulations in force in your area. The same  
applies for general rules of occupational health and safety.  
WARNING. Do not stare directly at the laser beam.  
A hazard may exist if you deliberately stare into the beam,  
please observe all safety rules as follows;  
The laser shall be used and maintained in accordance  
with the manufacturer’s instructions.  
Never aim the beam at any person or an object other  
than the workpiece.  
The laser beam shall not be deliberately aimed at  
personnel and shall be prevented from being directed  
towards the eye of a person for longer than 0.25s.  
Always ensure the laser beam is aimed at a sturdy  
workpiece without reflective surfaces. I.e. wood or rough  
coated surfaces are acceptable. Bright shiny reflective  
sheet steel or the like is not suitable for laser use as  
the reflective surface could direct the beam back at the  
operator.  
WARNING. When using power tools, basic safety  
precautions should always be taken to reduce the risk of  
fire, electric shock and personal injury. Also, please read  
and heed the advice given in the additional important  
safety instructions.
