GENERAL SAFETY INSTRUCTIONS
WARNING. Read all safety warnings and all
instructions. Failure to follow the warnings and instructions
may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains-
operated (corded) power tool or battery operated (cordless)
power tool.
1. WORK AREA SAFETY
a. Keep work area clean and well lit. Cluttered and dark
areas invite accidents.
b. Do not operate power tools in explosive
atmospheres, such as in the presence of flammable
liquids, gases or dust. Power tools create sparks which
may ignite the dust or fumes.
c. Keep children and bystanders away while operating
a power tool. Distractions can cause you to lose control.
2. ELECTRICAL SAFETY
a. Power tool plugs must match the outlet. Never modify
the plug in any way. Do not use any adaptor plugs
with earthed (grounded) power tools. Unmodified plugs
and matching outlets will reduce risk of electric shock.
b. Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
c. Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of
electric shock.
d. Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges or
moving parts. Damaged or entangled cords increase the
risk of electric shock.
e. When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use of a cord
suitable for outdoor use reduces the risk of electric shock.
f. If operating a power tool in a damp location is
unavoidable, use a residual current device (RCD)
protected supply. Use of an RCD reduces the risk of
electric shock.
3. PERSONAL SAFETY
a. Stay alert, watch what you are doing and use
common sense when operating a power tool.
Do not use a power tool while you are tired or under
the influence of drugs, alcohol or medication. A moment
of inattention while operating power tools may result in
serious personal injury.
b. Use safety equipment. Always wear eye protection.
Safety equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protection used for
appropriate conditions will reduce personal injuries.
c. Avoid accidental starting. Ensure the switch is in the
off position before plugging in. Carrying power tools with
your finger on the switch or plugging in power tools that
have the switch on invites accidents.
d. Remove any adjusting key or wrench before
turning the power tool on. A wrench or a key left
attached to a rotating part of the power tool may result
in personal injury.
e. Do not overreach. Keep proper footing and balance
at all times. This enables better control of the power tool
in unexpected situations.
f. Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing and gloves away from
moving parts. Loose clothes, jewellery or long hair can be
caught in moving parts.
g. If devices are provided for the connection of dust
extraction and collection facilities, ensure these are
connected and properly used. Use of these devices
can reduce dust related hazards.
4. POWER TOOL USE AND CARE
a. Do not force the power tool. Use the correct power tool
for your application. The correct power tool will do the job
better and safer at the rate for which it was designed.

GB
5
b. Do not use the power tool if the switch does not turn
it on and off. Any power tool that cannot be controlled
with the switch is dangerous and must be repaired.
c. Disconnect the plug from the power source before
making any adjustments, changing accessories, or
storing power tools. Such preventive safety measures
reduce the risk of starting the power tool accidentally.
d. Store idle power tools out of the reach of children and
do not allow persons unfamiliar with the power tool
or these instructions to operate the power tool. Power
tools are dangerous in the hands of untrained users.
e. Always unplug your power tool when leaving
unattended. Such preventative safety measures
reduce the risk of starting the power tool accidentally
by untrained users.
f. Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and
any other condition that may affect the power tools
operation. If damaged, have the power tool repaired
before use. Many accidents are caused by poorly
maintained power tools.
g. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
h. Use the power tool, accessories and tool bits etc.,
in accordance with these instructions and in the
manner intended for the particular type of power
tool, taking into account the working conditions and
the work to be performed. Use of the power tool for
operations different from those intended could result in
a hazardous situation.
5. SERVICE
a. Have your power tool serviced by a qualified repair
person using only identical replacement parts.
This will ensure that the safety of the power tool is maintained.
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.

Additional safety rules for mitre saws
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.
Your tool is double insulated for additional protection against

GB
a possible electrical insulation failure within the tool.
Always remove the plug from the mains socket before
making any adjustments or maintenance, including
changing the blade.
• When operating the saw, use safety equipment including
safety goggles or shield, ear protection, dust mask and
protective clothing including safety gloves.
• Ensure that there is adequate general or localised
lighting.
• Do not use the saw unless the guards are in place.
• Do not use the saw to cut metal or masonry.
• Do not let anyone under 18 years operate this saw.
• Ensure that the operator is adequately trained in the use,
adjustment and operation of the machine.
• Do not use this saw to cut firewood.
• Keep the area free of tripping hazards.
• Report faults in the machine, including guards and saw
blades, as soon as they are discovered.
• Ensure that the machine is always fixed to a bench,
whenever possible.
• Always stand to one side when operating the saw.
• Never use a cracked or distorted saw blade.
• When cutting round wood, use clamps that prevent the
workpiece from turning on both sides of the blade.
• Never use your hands to remove sawdust, chips or waste
close by the blade.
• Use only blades as recommended by the manufacturer
and which conform to EN 847-1.
• Do not use blades of High Speed Steel (HSS blades).
• If the table insert is damaged or worn, have it replaced by
an authorised service centre.
• Rags, cloths, cord and string and the like should never be
left around the work area.
• Avoid cutting nails. Inspect the workpiece and remove all
nails and other foreign objects before beginning sawing.
• Support the work properly.
• Refrain from removing any cut-offs or other parts of the
workpiece from the cutting area whilst the machine is
running and the saw head is not in the rest position.
• Do not attempt to free a jammed blade before first
switching off the machine.
• Do not slow or stop a blade with a piece of wood. Let the
blade come to rest naturally.
• 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.
• 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”. Switch off at
the mains and remove the plug immediately.
• Never saw near combustible liquids or gases.
• Note the direction of rotation of the motor and the blade.
• Do not lock the movable guard in the open position and
always ensure that it is working properly, freely rotating
and returning to fully cover the teeth of the blade.
• Connect the saw to a dust collection devise and ensure
that it is operated properly. As the operator of the saw,
please make sure that you understand factors that
influence exposure to dust, including the type of material
to be machined, the importance of local extraction and
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.

GB

• 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.

Unpacking
Due to modern mass production techniques, it is unlikely
that your GMC Power Tool is faulty or that a part is missing.
If you find anything wrong, do not operate the tool until the
parts have been replaced or the fault has been rectified.
Failure to do so could result in serious personal injury.
1. Remove all loose parts from the carton.
2. Remove the packing materials from around the saw.
3. Using the carrying handle (8) carefully lift the saw from
the carton and place it on a level work surface.
4. The saw has been shipped with the saw arm locked in
the down position. To release the saw arm, push down
on the top of the saw arm, pull on the release knob (6),
rotate it 45° and let go, slowly raise the saw arm.
WARNING. Do not lift the saw whilst holding on to the
guards. Use the carrying handle (8).
Transportation
Lift the mitre saw only when the
saw arm is locked in the down
position, the saw is switched
off and the plug is removed
from the power point.
Only lift the saw by the
carrying handle (8) or outer
castings (Fig. A). Do not lift
the saw using the guard or
operating handle (7).
Bench mounting
The saw base has holes in
each corner to facilitate bench
mounting (Fig. B).
1. Mount the saw to a level,
horizontal bench or work
table using bolts (not
supplied) and fix the saw to
the bench using 4 bolts.
2. If desired, you can mount the saw to a piece of 13mm or
thicker plywood which can then be clamped to your work
support or moved to other job sites and re-clamped.
CAUTION. Make sure that the mounting surface is not
warped as an uneven surface can cause binding and
inaccurate sawing.
Stabiliser bar
When the saw is not fitted
to a bench, always fit the
stabiliser bar (40) into the
holes at the rear of the saw
base (Fig. C). The stabiliser
helps prevent the saw from
tipping backwards when the
slide action is used.
Release knob
The release knob (6) is
provided for holding the
cutting head down whilst
transporting or storing the
mitre saw (Fig. D). The saw
must never be used with
the release knob locking the

Mitre table lock
The mitre table lock (25) is
used to lock the table at the
desired mitre angle (Fig. F).
The mitre saw cuts from 0°
to 45° both left and right. To
adjust the mitre angle loosen
the mitre table lock and using
the mitre table handle adjust
the mitre angle to the desired
position. The mitre table
features positive click stops at 0°, 15°, 22.5°, 30° and 45°
for quick setting of common mitre angles.
WARNING. Be sure to tighten the mitre table lock before
making a cut. Failure to do so could result in the table
moving during the cut and cause serious personal injury.
Bevel lock
The bevel lock (16) is used to
set the blade at the desired
bevel angle (Fig. G). The
mitre saw bevel cuts from 0°
to 45° to the left and right. To
adjust the bevel angle loosen
the bevel lock and pull out the
0° bevel adjuster (18). Adjust
the saw arm to the desired
bevel angle.
WARNING. Be sure to tighten
the bevel lock before making a cut. Failure to do so could
result in the saw arm moving during the cut and cause
serious personal injury.0°
Bevel adjuster
The bevel adjuster (18)
needs to be pulled out before
the bevel angle can be
adjusted (Fig. H).
To return the saw arm to the vertical (0° bevel)
position move the saw arm to the left and push in the
0° bevel adjuster.
Return the saw blade to the vertical position, it will automatically
stop at the 0° bevel position. Tighten the bevel lock.
Clamp assembly
The clamp assembly (10) can be mounted to the fence,
either side of the saw blade, to suit the task at hand (Fig. I).
Use the clamp assembly lock (11) at the back of the fence
to secure the clamp assembly in position (Fig. J).
Spindle lock button
The spindle lock button (26)
prevents the blade in the
saw from rotating (Fig. K).
Depress and hold the
spindle lock button while
installing, changing, or
removing the blade.
Rotating lower
blade guard
The rotating lower blade
guard (12) provides
protection from both sides of
the blade (Fig. L). It retracts
over the upper blade guard
(9) as the saw is lowered into
the workpiece.

Dust bag
The dust bag (15) fits over
the dust extraction port (27).
For more efficient operation,
empty the dust bag when it
is no more than half full. This
allows better air flow through
the bag (Fig. M).
Attaching
the side bars
The side support bars (37)
help to support the material
when working with long
workpieces. There are two
location holes (38) for a
support bar on either side of
the table. Loosen the lock
screws (39) with the 6mm
hex key. Ensure the side
bars are fully inserted before
using them to support the
workpiece (Fig. N).
The side support bar
locking screws (39) must
be tightened to secure the
support bars in position
(Fig. O).
Trench depth
adjustment
In its normal position, the
trenching stop (31) permits
the saw blade to cut right
through a workpiece. When
the saw arm is lifted, the
trenching stop can be moved
to the left so that the trenching
depth adjustment screw (30)
contacts the stop as the saw
arm is lowered. (Fig. P). This
restricts the cut to a “trench” in the workpiece. The depth
of the trench can be adjusted with the trenching depth
adjustment screw (30) (Fig. Q) and locked in position with
the trenching depth lock nut (32) (Fig. R).
Turning on and off
1. To turn the saw on depress
and hold the on/off trigger
switch (24) (Fig. S).
2. To turn the saw off release
the on/off trigger switch (24).
Turning on the laser
line generator
The laser line generator emits
2 intense narrow beams of
pure red light to guide you as
you cut.
It improves operator cutting
vision, enables faster set-up,
increases accuracy and
improves safety. To turn on
the laser lines press the laser
light on/off switch (2) (Fig. T).
To turn off the laser press the
laser light on/off switch (2)
one more time.

Changing a blade
DANGER! Never try to use a blade larger than the stated
capacity of the saw. It might come into contact with the
blade guards. Never use a blade that is too thick to allow the
outer blade washer to engage with the flats on the spindle.
It will prevent the blade screw from properly securing the
blade on the spindle. Do not use the saw to cut metal or
masonry. Ensure that any spacers and spindle rings that
may be required suit the spindle and the blade fitted.
1. Make sure that the electrical
plug is removed from the
power point.
2. Push down on the operating
handle (7) and pull the
release knob (6) to
disengage the saw arm (5).

Cross-cutting (without slide action)
When cutting a narrow piece of wood it is not necessary to
use the slide mechanism. In these cases ensure that the
slide lock (29) is screwed down to prevent the saw arm
from sliding.
A crosscut is made by cutting
across the grain of the
workpiece. A 90º crosscut is
made with the mitre table set
at 0º (Fig. q). Mitre crosscuts
are made with the table set at
some angle other than zero.
1. Pull on the release knob
(6) and lift the saw arm (5)
to its full height.
2. Loosen the mitre lock (25).
3. Rotate the mitre table (21) until the pointer aligns with
the desired angle.
4. Retighten the mitre lock (25).
WARNING. Be sure to tighten the mitre lock before making
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 (37), 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.
8. It is possible to remove the clamp assembly (10) by
loosening the clamp assembly lock (11) and moving
it to the other side of the table. Make sure the clamp
assembly lock is tight before using the clamp (Fig. r).
9. Before turning on the saw,
perform a dry run of the
cutting operation to check
that there are no problems.
10. Hold the operating handle
(7) firmly and squeeze
the switch trigger (24).
Allow the blade to reach
maximum speed.
11. Press the release latch
(36) (Fig. s) and slowly
lower the blade into and
through the workpiece.
12. Release the switch trigger
(24) and allow the saw
blade to stop rotating
before raising the blade
out of the workpiece.
Wait until the blade stops
before removing the
workpiece.
Cross-cutting

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.
