SAFETY WARNINGS
WORK AREA
1. Keep the work area clean and well lit. Cluttered and dark areas invite
accidents.
2. 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.
3. Keep children and bystanders away while operating a power tool.
Distractions can cause you to lose control.
ELECTRICAL SAFETY
1. Power tool plugs must match the outlet. NEVER modify the plug in any way.
DO NOT use adapter plugs with earthed (grounded) power tools.
Unmodified plugs & matching outlets will reduce the risk of electric shock.
2. DO NOT expose power tools to rain or wet conditions. Water entering a
power tool will increase the risk of electric shock.
3. DO NOT abuse the power cable. NEVER use it for carrying, pulling or
unplugging the power tool. Keep the power cable away from heat, oil,
sharp edges or moving parts. Damaged or entangled cables increase the
risk of electric shock.
4. When operating a power tool outdoors, use an extension cable suitable for
outdoor use. Use of a cable suitable for outdoor use reduces the risk of
electric shock.
5. If operating the power tool in a damp location is unavoidable, use a
residual current device (RCD) protected supply.
PERSONAL SAFETY
1. 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 personal injury.
2. 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.
3. 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.
4. Remove any wrench before turning the power tool on. A wrench left
attached to a rotating part may result in personal injury.

4
Parts & Service: 020 8988 7400 / E-mail: [e-mail] or [e-mail]
5. DO NOT overreach. Keep proper footing and balance at all times. This
enables better control of the power tool in unexpected situations.
6. 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.
7. A laser beam can cause serious eye injury. DO NOT look into the laser
outlet.
POWER TOOL USE AND CARE
1. DO NOT force the power tool. Use the correct accessories for your
application. The correct power tool will do the job better and safer at the
rate which it was designed.
2. 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.
3. Disconnect the plug from the power source before changing accessories,
or storing power tools. Such preventive safety measures reduce the risk of
starting the power tool accidentally.
4. Store idle tools out of the reach of children and do not allow persons
unfamiliar with the power tool or these instructions to operate it. Power tools
are dangerous in the hands of untrained users.
5. 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.
6. Use the power tool and accessories in accordance with these instructions
and in the manner intended, 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.
ADDITIONAL SAFETY RULES FOR MITRE SAWS
1. Use clamps to support the workpiece whenever possible. If supporting the
workpiece by hand, you must always keep your hand at least 100 mm from
either side of the saw blade. DO NOT use this saw to cut pieces that are too
small to be securely clamped or held by hand. If your hand is placed too
close to the saw blade there is an increased risk of injury from blade
contact.
2. The workpiece must be stationary and clamped or held against both the
fence and the table.

5
Parts & Service: 020 8988 7400 / E-mail: [e-mail] or [e-mail]
3. DO NOT feed the workpiece into the blade or cut "freehand" in any way.
Unrestrained or moving workpieces could be thrown at high speeds,
causing injury.
4. NEVER cross your hand over the intended line of cutting either in front or
behind the saw blade. Supporting the workpiece "cross handed" i.e.
holding the workpiece to the right of the saw blade with your left hand or
vice versa is very dangerous.
5. DO NOT reach behind the fence with either hand closer than 100 mm from
either side of the saw blade, to remove wood scraps, or for any other
reason while the blade is spinning. The proximity of the spinning saw blade
to your hand may not be obvious and you may be seriously injured.
6. Inspect your workpiece before cutting. If the workpiece is bowed or
warped, clamp it with the outside bowed face toward the fence. ALWAYS
make certain that there is no gap between the workpiece, fence and
table along the line of the cut. Bent or warped workpieces can twist or shift
and may cause binding on the spinning saw blade while cutting. There
should be no nails or foreign objects in the workpiece.
7. DO NOT use the saw until the table is clear of all tools, wood scraps, etc.,
except for the workpiece. Small debris or loose pieces of wood or other
objects that contact the revolving blade can be thrown with high speed.
8. Cut only one workpiece at a time. Stacked multiple workpieces cannot be
adequately clamped or braced and may bind on the blade or shift during
cutting.
9. Ensure the mitre saw is mounted or placed on a level, firm work surface
before use. A level and firm work surface reduces the risk of the mitre saw
becoming unstable.
10. Plan your work. Every time you change the bevel or mitre angle setting,
make sure the adjustable fence is set correctly to support the workpiece
and will not interfere with the blade or the guarding system. Without turning
the tool "ON" and with no workpiece on the table, move the saw blade
through a complete simulated cut to assure there will be no interference or
danger of cutting the fence.
11. Provide adequate support such as table extensions, saw horses, etc. for a
workpiece that is wider or longer than the table top. Workpieces longer or
wider than the mitre saw table can tip if not securely supported. If the cut-
off piece or workpiece tips, it can lift the lower guard or be thrown by the
spinning blade.
12. DO NOT use another person as a substitute for a table extension or as
additional support. Unstable support for the workpiece can cause the
blade to bind or the workpiece to shift during the cutting operation pulling
you and the helper into the spinning blade.

Parts & Service: 020 8988 7400 / E-mail: [e-mail] or [e-mail]
13. The cut-off piece must not be jammed or pressed by any means against
the spinning saw blade. If confined, i.e. using length stops, the cut-off
piece could get wedged against the blade and thrown violently.
14. ALWAYS use a clamp or a fixture designed to properly support round
material such as rods or tubing. Rods have a tendency to roll while being
cut, causing the blade to "bite" and pull the work with your hand into the
blade.
15. Let the blade reach full speed before contacting the workpiece. This will
reduce the risk of the workpiece being thrown.
16. If the workpiece or blade becomes jammed, turn the mitre saw off. Wait for
all moving parts to stop and disconnect the plug from the power source.
Then work to free the jammed material.
17. After finishing the cut, release the switch, hold the saw head down and
wait for the blade to stop before removing the cut-off piece. Reaching
with your hand near the coasting blade is dangerous.
18. Hold the handle firmly when making an incomplete cut or when releasing
the switch before the saw head is completely in the down position. The
resistance of the saw may cause the saw head to be suddenly pulled
downward.
SAFETY FOR THE HANDLING OF SAW BLADES
1. Check the condition of the blade before using the saw.
2. DO NOT use damaged or deformed saw blades.
3. ONLY use saw blades recommended by the manufacturer.
4. Saw blades designed to cut wood and similar materials must comply with
EN 847-1.
5. DO NOT use saw blades made of high-speed alloy steel (HSS steel). ONLY
use replacement blades from your CLARKE dealer.
6. Observe the saw blade direction of rotation.
7. Clean any grease, oil and water off of the clamping surfaces.
8. ONLY use the saw blade supplied for cutting wood, never for the cutting of
metals.
9. ONLY use blades with diameters shown by the markings on the saw.
10. Replace damaged or worn saw blades immediately.
11. If the saw blade overheats, stop the machine. Allow the saw blade to cool
down before using the machine again.

LASER SAFETY
1. DO NOT look directly into the laser beam with unprotected eyes.
2. NEVER look into the path of the beam.
3. NEVER point the laser beam towards reflecting surfaces and persons or
animals. Even a laser beam with a low output can cause damage to the
eyes.
4. NEVER open the laser module. Unexpected exposure to the beam can
occur.
5. The laser may not be replaced with a different type of laser.
6. Repairs of the laser may only be carried out by the laser manufacturer or
an authorised representative.
CAUTION: METHODS OTHER THAN THOSE SPECIFIED HERE CAN RESULT IN
DANGEROUS RADIATION EXPOSURE.

Parts & Service: 020 8988 7400 / E-mail: [e-mail] or [e-mail]
RESIDUAL RISKS
1. Despite all precautions having been met, some non-obvious residual risks
may still remain.
2. Residual risks can be minimised if the safety warnings are observed along
with the whole of the operating instructions.
3. DO NOT load the machine unnecessarily. Excessive pressure when sawing
will quickly damage the saw blade which results in reduced output of the
machine in the processing and in cut precision.
4. When cutting plastic material, please always use clamps: the parts being
cut must always be fixed between the clamps.
5. Avoid accidental starting of the machine: the operating button may not
be pressed when inserting the plug in an outlet.
6. Hands must never enter the cutting zone when the machine is in operation.
