suitable for outdoor use reduces the risk of electric shock.
General safety rules
WARNING. Read 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 listed below refers to your mains operated
(corded) power tool or battery operated (cordless)
power tool.
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.
Save these instructions
1. Work area
a. Keep work area clean and well lit. Cluttered and dark
areas invite accidents.
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.
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. 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.
c. Keep children and bystanders away while
operating a power tool. Distractions can cause you to
lose control.
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.
2. Electrical safety
a. 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.
e. Do not overreach. Keep proper footing and balance at
all times. This enables better control of the power tool in
unexpected situations.
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.
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.
c. Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of
electric shock.
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.
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.

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.
Additional safety rules for laser lights
The laser light/laser radiation used in the GMC REDEYE®
system is Class 2 with maximum 1mW and 650nm
wavelengths. These lasers do not normally present an
optical hazard, although staring at the beam may cause
flash blindness.
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.
WARNING. Do not stare directly at the laser beam.
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.
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.
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.
• 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.
e. 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.
• 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.
f. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
• 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.
g. 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.

Causes and operator prevention of kickback:
Additional safety rules for circular saws
• 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;
WARNING! The warnings, precautions, and instructions
discussed in this manual cannot cover all possible
conditions and situations that may occur. The operator must
understand that common sense and caution are factors
which cannot be built into this product, but must be supplied
by the operator.
• 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.
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.
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.
b. Do not reach underneath the workpiece. The guard
cannot protect you from the blade below the workpiece.
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.
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.
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.
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.
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.
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.
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.

e. Do not use dull or damaged blades. Unsharpened
or improperly set blades produce narrow kerf causing
excessive friction, blade binding and kickback.
Accessories
The GMC LS1800M Circular Saw is supplied with the
following accessories as standard:
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.
1. Blade (fitted)
2. Blade wrench
3. Rip fence
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.
4. Carry case
5. Instruction manual
Unpacking
The protruding blade may cut objects that can
cause kickback.
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.
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.
Assembly
The GMC circular saw is packed, fully assembled except for
the rip fence.
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.
e. Do not use Abrasive wheels

Overview
Note. Always use the correct blade depth setting.
The correct blade depth setting for all cuts should not be
more than (6.35mm) 1/4” below the material being cut.
Allowing more depth will increase the chance of kickback
and result in a rough cut.
You have purchased an 1800W Magnesium Circular Saw
with the GMC REDEYE® laser line generator system.
Please refer to the safety instructions given earlier in this
manual for important instructions regarding the use of the laser.
The saw is capable of ripping and cross cutting hardwoods,
softwoods and man made boards quickly, accurately and safely.
Adjusting the bevel angle
CAUTION. Always ensure that the saw is switched off
and unplugged from the power supply before making
any adjustments.
By loosening the bevel adjustment knob (9), the body and
the blade of the saw can be tilted to any angle up to 55° for
making angle cuts. Please note that the maximum depth of
cut is reduced when cutting at an angle.
1. The saw can be adjusted to cut at any angle between
0° and 55°. 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.
A fixed upper blade guard (16) encloses the upper part of
the blade. As the saw advances through the work piece,
the pivoting lower blade guard (14) 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.
2. Loosen the bevel adjustment knob (9) located at the front
of the base plate (Fig. C).
