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.

the proper adjustment of hoods/baffles/shoots of your
dust extraction system. We recommend that you always
wear a dust mask when operating this saw.
• Wear gloves when handling saw blades and
rough materials.
• Saw blades shall be carried in a holder
wherever possible.
• Select saw blades in relation to the material being cut.
• Use correctly sharpened saw blades and observe the
maximum speed marked on the blade.
• Take additional care when trenching (slotting).
• The mitre saw can be safely carried by the carrying
handle but only once it has been removed from the mains
power and secured in the locked down position.
• Ensure that the arm is properly secure when bevelling.
• Keep the floor area around the machine level, well
maintained and free of loose materials.
• Ensure that you are trained in the use, adjustment and
operation of the machine.
• Do not remove any cut-offs from the cutting area until
the guard is fully locked in placed and the blade has
come to rest.
• 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.

a cut. Failure to do so could result in the table moving
during the cut and cause serious personal injury.
5. Place the workpiece flat on the table with one edge
securely against the fence (19). If the board is warped,
place the convex side against the fence. If the concave
side is placed against the fence, the board could break
and jam the blade.
6. When cutting long pieces of timber, support the opposite
end of the timber with the side support bars (32), a roller
stand or a work surface that is level with the saw table.
7. Use the clamp assembly (10) to secure the workpiece
wherever possible.

Compound mitre cut
A compound mitre cut involves
using a mitre angle and a
bevel angle at the same
time (Fig. p). It is used in
making picture frames, to cut
mouldings, making boxes
with sloping sides and for roof
framing. Always make a test
cut on a piece of scrap wood before cutting into the
good material.

Adjusting the laser lines
The lower laser is factory set to emit a laser line along the
right-hand side of the blade. The upper laser is factory set
to emit a laser line to the lefthand side of the blade. This
upper laser can be adjusted by
the operator to suit blades of
different kerf widths.
To adjust the position of
the upper laser, proceed
as follows:
1. Remove the laser cover by
pulling it towards you.
2. Switch on the laser lights with the on/off switch (2) (Fig. q).
3. Using a Phillips head
screwdriver (not supplied),
adjust the position of the
line from the upper laser
by turning the laser pitch
control (4) (Fig. r).
4. Adjust until the left-hand
laser line is aligned with the
left-hand side of the blade.
5. Switch off the laser lights.

WARNINGS
Do not stare directly at the
laser beam.
Never aim the beam at any
person or an object other than
the workpiece.
Do not deliberately aim the
beam at personnel and
ensure that it is not 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. Wood or rough coated
surfaces are acceptable. Bright shiny reflective surfaces
are not suitable for laser use as the reflective surface could
direct the beam back at the operator.
Always remember to switch off the laser on/off switch (2)
after finishing a job. Only turn the laser beam on when the
workpiece is on the mitre saw table.
1. Mark the line of the cut on the workpiece.
2. Adjust the angle of mitre and bevel of the cut as required.
3. Switch on the laser light on/off switch (2).
4. Clamp the workpiece in position using the laser lines to
align the blade with the pencil mark on the workpiece.

5. Plug in the machine and start the motor.
6. Press the release latch (31).
7. When the blade is at its maximum speed (approximately
2 seconds), lower the blade through the workpiece.
8. After completing the cut, switch off the laser light on/off
switch (2).
9. After each use, clean the laser light assembly (1) as
described below:
• Switch off the laser light switch (2) and then remove the
plug from the power point.
• With the saw arm (5) in the raised position, use a
soft brush to dust away the sawdust build-up around
the assembly.
Note. Wear eye protection whilst brushing the dust away.
Maintenance
WARNING. Always ensure that the tool is switched off and
the plug is removed from the power point before making
and adjustments or maintenance procedures.
Power cord maintenance
If the supply cord needs replacing, the task must be carried
out by the manufacturer, the manufacturer’s agent, or an
authorised service centre in order to avoid a safety hazard.
Cleaning
1. Keep the tool’s air vents unclogged and clean at all times.
2. Remove dust and dirt regularly. Cleaning is best done
with a soft brush or a rag.
3. Re-lubricate all moving parts at regular intervals.
4. Never use caustic agents to clean plastic parts.
CAUTION. Do not use cleaning agents to clean the
plastic parts of the saw. A mild detergent on a damp cloth
