Safety rules for laser lights  
The laser light/laser radiation used in the GMC LightSabre  
system is Class 2 with maximum 1mW and 400nm–  
700nm wavelengths. These lasers do not normally present  
an optical hazard, although staring at the beam may  
cause flash blindness.  
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.  
regulations in force in your area. The same applies for  
general rules of occupational health and safety.  
Never aim the beam at any person or an object other  
than the work piece.  
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 work  
piece 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.  
Do not change the laser light assembly with a different  
type. Repairs must be carried out by the laser  
manufacturer or an authorized agent.  
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.  
1. Keep the work area clean and tidy. Cluttered work  
areas and benches invite accidents and injury.  
2. Consider the environment in which you are working.  
Do not use power tools in damp or wet locations. Keep  
the work area well lit. Do not expose power tools to  
rain. Do not use power tools in the presence of  
flammable liquids or gases.  
3. Keep visitors away from the work area. All visitors  
and onlookers, especially children and infirm persons,  
should be kept well away from where you are working.  
Do not let others in the vicinity make contact with the

Additional safety rules for jigsaws  
Warnings. Before connecting a tool to a power source  
(mains switch power point receptacle, outlet, etc.) be sure  
that the voltage supply is the same as that specified on  
the nameplate of the tool. A power source with a voltage  
greater than that specified for the tool can result in  
serious injury to the user, as well as damage to the tool.  
If in doubt, do not plug in the tool. Using a power source  
with a voltage less than the nameplate rating is harmful  
to the motor.  
Always remove the plug from the mains socket before  
making any adjustments or maintenance, including  
changing the blade.  
Ensure that the lighting is adequate.  
Do not use the saw unless the guards are in place  
Keep the shoe flat on the work piece.  
Do not put pressure on the saw, such that it slows the  
motor down. Allow the saw blade to cut without  
pressure. You will get better results and you will be  
taking better care of your tool.  
Keep the area free of tripping hazards.  
Do not let anyone under 18 years operate this jigsaw.  
Only use blades in good condition.

Before cutting, check that there is sufficient clearance  
for the blade under the work piece.  
Do not touch the blade after operation. It will be very  
hot.  
Always hold the saw on parts that are insulated. If you  
accidentally cut into hidden wiring or the saw’s own  
cable, the metal parts of the saw will become ‘live.  
Check the voltage on mains matches that of rating plate  
before plugging in the tool.  
Keep your hands away from under the work piece.  
Do not secure the jigsaw upside down in a vice or work  
bench and use it as a saw bench. This can lead to  
serious injury.  
When using the jigsaw, use safety equipment including  
safety goggles or shield, ear defenders, dust mask and  
protective clothing including safety gloves.  
Never use your hands to remove sawdust, chips or waste  
close by the blade.  
Rags, cloths, cord, string and the like should never be  
left around the work area.  
Avoid cutting nails. Inspect the work piece and remove  
all nails and other foreign objects before beginning  
sawing.  
Wear goggles  
Wear ear defenders  
Wear a breathing mask  
Support the work properly.  
Never reach over the blade to remove waste or off cuts.  
Do not attempt to free a jammed blade before first  
switching off the machine.  
If you are interrupted when operating the saw,  
complete the process and switch off before looking up.  
Periodically check that all nuts, bolts and other fixings  
are properly tightened.  
Do not store materials or equipment above a machine  
in such a way that they could fall into it.
