Safety rules for laser lights
The laser light/laser radiation used in the GMC REDEYE®
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.
• 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.
• Do not change the laser light assembly with a different
type. Repairs must be carried out by the laser
manufacturer or an authorised agent.
CAUTION. Use of controls or adjustments or performance
of procedures other than those specified herein may result
in hazardous radiation exposure.
Please refer to the relevant Australian standards, AS 2397
and AS/NZS2211 for more information on Lasers.

General safety instructions
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. 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.
Even when the tool is used as prescribed it is not
possible to eliminate all residual risk factors. The following
hazards may arise in connection with the tool’s construction
and design:
• Contact with the blade.
• Kickback of workpiece and parts of workpiece.
• Blade fracture.
• Catapulting of blade pieces.
• Damage to hearing if effective earmuffs are not worn.
• Harmful emissions of sawdust when the machine is
used in closed rooms. Always use supplementary dust
extraction where possible.
• Do not use blades that are deformed or cracked.
• Always remove the plug from the mains socket before
making any adjustments or maintenance, including
changing the blade.
To ensure safe operation of the mitre saw you must follow
these guidelines –
• Select the correct blade for the material to be cut.
• Do not use the saw to cut materials other than those
recommended by the manufacturer.
• The mitre saw can be safely carried by the main handle
but only once it has been removed from the mains power
and secured in the locked down position.
• Do not use the saw without the guards in position, in
good working order and properly maintained.
• Ensure that the arm is properly secure when bevelling.
• Keep the floor area around the machine level, well
maintained and free of loose materials.
• Provide adequate lighting.
• Ensure that you are trained in the use, adjustment and
operation of the machine.
• Use correctly sharpened blades and observe the
maximum speed marked on the blade.
• Do not remove any cut-offs from the cutting area until
the guard is fully locked in place and the blade has come
to rest.
• Ensure that the mitre saw is fixed to a bench wherever
possible.
• When cutting long pieces which extend well over
the table width ensure that the ends are adequately
supported at the same height as the saw table top.
Supports should be positioned in such a way to ensure
that the workpiece does not fall to the ground once
the cut has been made. A number of supports at
regular intervals may be required if the workpiece is
extremely long.
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
6
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 tool or
extension cord.
4. Store tools safely. When not in use, tools should be
locked up out of reach.
5. Do not force the tool. The tool will do the job better and
safer working at the rate for which it was designed.
6. Use the correct tool for the job. Do not force small
tools or attachments to do the job best handled by a
heavier duty tool. Never use a tool for a purpose for
which it was not intended.
7. Dress correctly. Do not wear loose clothing or
jewellery. They can be caught in moving parts. Rubber
gloves and non-slip footwear are recommended when
working outdoors. If you have long hair, wear a protective
hair covering.
8. Use safety accessories. Safety glasses and earmuffs
should always be worn. A face or dust mask is also
required if the drilling operation creates dust.
9. Do not abuse the power cord. Never pull the cord to
disconnect the tool from the power point. Keep the cord
away from heat, oil and sharp edges.
10. Secure the workpiece. Use clamps or a vice to hold
the workpiece. It is safer than using your hand and
frees both hands to operate the tool.
11. Do not overreach. Keep your footing secure and
balanced at all times.
12. Look after your tools. Keep tools sharp and clean for
better and safer performance. Follow the instructions
regarding lubrication and accessory changes. Inspect
tool cords periodically and, if damaged, have them
repaired by an authorised service facility. Inspect
extension cords periodically and replace them if
damaged. Keep tool handles dry, clean and free from
oil and grease.
13. Disconnect idle tools. Switch off the power and
disconnect the plug from the power point before
servicing, when changing accessories and when the
tool is not in use.
14. Remove adjusting keys and wrenches. Check to see
that keys and adjusting wrenches are removed from the
tool before switching on.
15. Avoid unintentional starting. Always check that the
switch is in the OFF position before plugging in the tool
to the power supply. Do not carry a plugged in tool with
your finger on the switch.
16. Use outdoor rated extension cords. When a tool
is used outdoors, use only extension cords that are
intended for outdoor use and are so marked.
17. Stay alert. Watch what you are doing. Use common
sense. Do not operate a power tool when you are tired.
18. Check for damaged parts. Before using a tool, check
that there are no damaged parts. If a part is slightly
damaged, carefully determine if it will operate properly
and perform its intended function. Check for alignment
of moving parts, binding of moving parts, breakage
of parts, proper mounting and any other conditions
that may affect the operation of the tool. A part that is
damaged should be properly repaired or replaced by
an authorised service facility, unless otherwise
indicated in this Instruction Manual. Defective switches
must be replaced by an authorised service facility.
Do not use a tool if the switch does not turn the tool
on and off correctly.
19. Guard against electric shock. Prevent body contact
with grounded objects such as water pipes, radiators,
cookers and refrigerator enclosures.
20. Use only approved parts. When servicing, use only
identical replacement parts. Use an authorised service
facility to fit replacement parts.
