Personal safety
General safety rules
• 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.
WARNING! Read and understand all instructions.
Failure to follow all instructions listed below may result
in electric shock, fire and/or serious injury. The term
“power tool” in all of the warnings below refers to your
mains-operated (corded) power tool or battery-operated
(cordless) power tool.
• Use safety equipment. Always wear eye protection.
Safety equipment such as a dust mask, non-skid
safety shoes, hard hat, or hearing protection used for
appropriate conditions will reduce personal injuries.
• 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.
• Remove any adjusting key or wrench before turning the
tool on. A wrench or a key that is left attached to a
rotating part of the power tool may result in personal
injury.
Save these instructions
Work area
• Keep work area clean and well lit. Cluttered and dark
areas invite accidents.
• 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.
• Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
Electrical safety
• Power tool plugs must match the outlet. Never modify
the plug in any way. Do not use any adapter plugs with
earthed (grounded) power tools. Unmodified plugs and
matching outlets will reduce risk of electric shock.
• 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.
• Do not overreach. Keep proper footing and balance at
all times. This enables better control of the power tool
in unexpected situations.
• 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.
• If devices are provided for the connection of dust
extraction and collection facilities ensure that these are
connected and properly used. Use of these devices can
reduce dust-related hazards.
• Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of
electric shock.
• 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.
• When operating a power tool outdoors, use an
outdoor extension cord suitable for outdoor use. Use
of a cord suitable for outdoor use reduces the risk of
electric shock.
Power tool use and care
• 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.
• 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.

• 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.
• 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.
• Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and any
other condition that may affect the power tool’s
operation. If damaged, have the power tool repaired
before use. Many accidents are caused by poorly
maintained power tools.
Additional 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 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.
• Keep cutting tools sharp and clean. Properly maintained
cutting tools with sharp cutting edges are less likely to
bind and are easier to control.
• 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 only be carried out by the laser
manufacturer or an authorised agent.
• 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 intended could result in a hazardous
situation.
Service
• Have your power tool serviced by a qualified repair
personnel using only identical replacement parts.
This will ensure that the safety of the power tool is
maintained.
LASER LIGHT. LASER RADIATION
Do not stare into beam.
Only turn laser beam on when tool
is on work piece. Class 2 laser product
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.

• When the blade is pinched or bound tightly by the kerf
closing down, the blade stalls and the motor reaction
drives the unit rapidly back toward the operator;
• If the blade becomes twisted or misaligned in the cut,
the teeth at the back edge of the blade can dig into
the top surface of the wood causing the blade to climb
out of the kerf and jump back toward the operator.
Kickback is the result of saw misuse and/or incorrect
operating procedures or conditions and can be avoided by
taking proper precautions as given below.
a) Maintain a firm grip with both hands on the saw and
position your arms to resist kickback forces. Position
your body to either side of the blade, but not in line
with the blade. Kickback could cause the saw to jump
backwards, but kickback forces can be controlled by
the operator, if proper precautions are taken.
Additional safety rules for circular saws
DANGER
a) Keep hands away from cutting area and the blade.
Keep your second hand on auxiliary handle, or motor
housing. If both hands are holding the saw, they
cannot be cut by the blade.
b) Do not reach underneath the workpiece. The guard
cannot protect you from the blade below the
workpiece.
c) Adjust the cutting depth to the thickness of the
workpiece. Less than a full tooth of the blade teeth
should be visible below the workpiece.
d) Never hold piece being cut in your hands or across
your leg. Secure the workpiece to a stable platform. It
is important to support the work properly to minimize
body exposure, blade binding, or loss of control.
b) When blade is binding, or when interrupting a cut
for any reason, release the trigger and hold the saw
motionless in the material until the blade comes to a
complete stop. Never attempt to remove the saw from
the work or pull the saw backward while the blade
is in motion or kickback may occur. Investigate and
take corrective actions to eliminate the cause of blade
binding.
c) When restarting a saw in the workpiece, centre the
saw blade in the kerf and check that saw teeth are not
engaged into the material. If saw blade is binding, it
may walk up or kickback from the workpiece as the
saw is restarted.
e) Hold power tool by insulated gripping surfaces when
performing an operation where the cutting tool may
contact hidden wiring or its own cord. Contact with a
“live” wire will also make exposed metal parts of the
power tool “live” and shock the operator.
f) When ripping always use a rip fence or straight edge
guide. This improves the accuracy of cut and reduces
the chance of blade binding.
g) Always use blades with correct size and shape
(diamond versus round) of arbour holes. Blades that
do not match the mounting hardware of the saw will
run eccentrically, causing loss of control.
h) Never use damaged or incorrect blade washers or bolt.
The blade washers and bolt were specially designed
for your saw, for optimum performance and safety of
operation.
d) Support large panels to minimise the risk of blade
pinching and kickback. Large panels tend to sag under
their own weight. Supports must be placed under the
panel on both sides, near the line of cut and near the
edge of the panel.
Causes and operator prevention of kickback:
• Kickback is a sudden reaction to a pinched, bound or
misaligned saw blade, causing an uncontrolled saw to
lift up and out of the workpiece toward the operator;

e) Do not use dull or damaged blades. Unsharpened or
improperly set blades produce narrow kerf causing
excessive friction, blade binding and kickback.
f) Blade depth and bevel adjusting locking levers must
be tight and secure before making cut. If blade
adjustment shifts while cutting, it may cause binding
and kickback.
g) Use extra caution when making a “plunge cut” into
existing walls or other blind areas. The protruding
blade may cut objects that can cause kickback.
a) Check lower guard for proper closing before each use.
Do not operate the saw if lower guard does not move
freely and close instantly. Never clamp or tie the lower
guard into the open position. If saw is accidentally
dropped, lower guard may be bent. Raise the lower
guard with the retracting handle and make sure it
moves freely and does not touch the blade or any
other part, in all angles and depths of cut.
b) Check the operation of the lower guard spring. If the
guard and the spring are not operating properly, they
must be serviced before use. Lower guard may operate
sluggishly due to damaged parts, gummy deposits, or
a build-up of debris.
c) Lower guard should be retracted manually only for
special cuts such as “plunge cuts” and “compound
cuts.” Raise lower guard by retracting handle and as
soon as blade enters the material, the lower guard
must be released. For all other sawing, the lower guard
should operate automatically.
d) Always observe that the lower guard is covering the
blade before placing saw down on bench or floor. An
unprotected, coasting blade will cause the saw to walk
backwards, cutting whatever is in its path. Be aware of
the time it takes for the blade to stop after switch is
released.

By loosening the bevel adjustment lever (8), the body
and the blade of the saw can be tilted to any angle up to
45° for making angle cuts. Please note that the maximum
depth of cut is reduced when cutting at an angle.
A fixed guard (15) encloses the upper part of the blade.
As the saw advances through the work piece, the pivoting
lower blade guard (13) is pushed back by the edge of
the wood to expose only that part of the blade which
is needed. When the blade clears the work, the spring
loaded lower blade guard snaps back to completely
enclose the blade.

Please refer to the safety instructions given earlier in this
manual for important instructions regarding the use of
the laser.
4. Tighten the depth
locking lever (18).
The saw is capable of ripping and cross cutting
hardwoods, softwoods and man made boards quickly,
accurately and safely.
If the tool becomes too hot, let it run under no load for
2–3 minutes to cool the motor.
The quality of the cut will improve as the number of blade
teeth increases.
The blade cuts on an upward stroke and may chip the
uppermost surface or edges of your work piece. When
cutting, ensure that your uppermost surface is a
non-visible surface when your work is finished.

Note. Always use the correct
blade depth setting. The
correct blade depth setting for
all cuts should not be more
than 6mm below the material
being cut. Allowing more
depth will increase the chance
of kickback and result in a
rough cut.
Note. Always make a trial
cut in a scrap piece of
material along a guideline
to determine how much you
should offset the blade from
the guideline to make an
accurate cut.
Adjusting the bevel
setting
CAUTION. Always ensure that the saw is switched off
and unplugged from the power supply before making any
adjustments.
Adjusting the
bevel angle
CAUTION. Always ensure that
the saw is switched off and
unplugged from the power
supply before making any
adjustments.
1. Ensure power is
disconnected from the
mains socket.
2. With the saw turned upside
down and the lower guard
fully retracted, check that
the saw blade is at 90° to
the base.
1. The saw can be adjusted to
cut at any angle between
0° and 45°. When making
45° bevel cuts, there is
a notch (23) in the saw
base to help you line up
the blade with the line of
cut. Align your line of cut
with the inner blade guide
notch on the base of the
saw when making 45°
bevel cuts.
3. If adjustment is necessary,
adjust as follows.
4. Loosen the lock nut of the
stop screw found beside the
parallel fence locking knob
