General safety rules
3. Personal safety
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.
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
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.
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. 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.
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.
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.
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.
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.
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.
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.
e. When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use of a cord

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.
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.
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. 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.
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.
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.
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.
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.
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.
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.
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;
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.
• 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;
Additional safety rules for circular saws
DANGER.
• 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.
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.

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.
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.
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.
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. 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.
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.
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.
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.
Contents of carton
The GMC CS011A Circular Saw is supplied with the
following accessories as standard:
• Blade (fitted)
• Blade key
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.
• Parallel fence
Unpacking
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.
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.
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

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.
1. The saw can be adjusted to cut at any angle between
0° and 45°.
By loosening the bevel adjustment knob (6), 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.
2. Loosen the bevel adjustment
knob (6) located at the front of
the base plate.
A fixed upper blade guard (13) encloses the upper part of
the blade. As the saw advances through the workpiece, the
pivoting lower blade guard (11) 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.
3. Tilt the body of the saw until
the required angle is reached
using the bevel scale (7) as a
guide.
4. Tighten the bevel adjustment
knob (6) to secure the base plate.
Adjusting the cutting depth
CAUTION. Always ensure that the saw is switched off
and unplugged from the power supply before making any
adjustments.
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.
1. Ensure that the saw is facing away from you.
Switching on and off
1. Connect the plug to the power supply.
2. Loosen the depth locking
lever (15).
2. Depress the lock-off button (2)
and squeeze the trigger
switch (1).
3. Hold the base plate flat against
the edge of the workpiece and
lift the body of the saw until the
blade is at the right depth. Use
the depth of cut indicator (16) to
determine the cutting depth.
3. The blade will take
approximately 2 seconds
to reach full speed.
4. Tighten the depth locking lever (15).
Note. When you release the
trigger, the machine turns off
and the lock-off button re-engages to prevent accidental
operation.
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.
CAUTION. Allow the blade to come to a complete standstill
before setting the saw down.

guide as follows:
2. Adjust the bevel setting to 0°.
a. Cutting at 90°
b. Cutting at 45°
3. Raise the lower blade guard
lever (10) to expose the saw
blade, firmly rest the front
of the base flat against the
workpiece with the rear handle
raised so the blade does not
touch the workpiece.
4. With the blade just clearing the workpiece, start the motor
by depressing the lock-off button (2) and squeezing the
trigger switch (1).
2. Rest the front edge of the
base on the workpiece. Start
the motor and let the blade
reach full speed
5. Always let the blade reach full speed (approximately 2
seconds) before you begin to cut into the workpiece.
6. Slowly lower the saw into the workpiece, using the front
of the base resting on the workpiece as a hinge point.
(approximately 2 seconds).
WARNING. As soon as the blade starts cutting the material,
release the lower blade guard lever.
3. Slowly push the saw forward
using both hands.
7. Once the base plate (12) is flat against the workpiece,
proceed cutting in a forward direction to the end of the
cut.
Note. When making a cut always
use steady, even pressure.
Forcing the saw causes rough cuts and could shorten the
life of the saw or cause kickback. Allow the blade and the
saw to do the work.
8. After completing your cut, release the trigger switch
and allow the blade to come to a complete stop. Do not
remove the saw from the workpiece while the blade is
moving.
Note. If the corners of your pocket cut are not completely
cut through, use a jigsaw or hand saw to finish the corners.
4. After completing your cut, release the switch (1) and
allow the blade to come to a complete stop. Do not
remove the saw from the workpiece while the blade is
moving.
Note. Since blade thickness varies, always make a trial cut
in scrap material along the guideline to check the accuracy
of the blade guide notches.
