SAFETY WARNINGS
General power tool safety warnings
WARNING: Read all safety warnings, instruc-
tions, illustrations and specications provided
with this power tool. Failure to follow all instructions
listed below may result in electric shock, re 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.
Work area safety
1. Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
2. Do not operate power tools in explosive atmo-
spheres, such as in the presence of ammable
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 any
adapter plugs with earthed (grounded) power
tools. Unmodied plugs and matching outlets will
reduce risk of electric shock.
2. Avoid body contact with earthed or grounded
surfaces, such as pipes, radiators, ranges and
refrigerators. There is an increased risk of elec-
tric shock if your body is earthed or grounded.
3. Do not expose power tools to rain or wet con-ditions. Water entering a power tool will increase
the risk of electric shock.
4. 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.
5. 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.
6. 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.
7. Power tools can produce electromagnetic elds (EMF) that are not harmful to the user.
However, users of pacemakers and other similar
medical devices should contact the maker of their
device and/or doctor for advice before operating
this power tool.
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 inuence of drugs, alcohol or medication. A moment of inattention while operating
power tools may result in serious personal injury.
2. Use personal protective equipment. Always
wear eye protection. Protective equipment such
as a dust mask, non-skid safety shoes, hard hat or
hearing protection used for appropriate conditions
will reduce personal injuries.
3. Prevent unintentional starting. Ensure the
switch is in the off-position before connecting
to power source and/or battery pack, picking
up or carrying the tool. Carrying power tools with
your nger on the switch or energising power tools
that have the switch on invites accidents.
4. 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.
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 and clothing away
from moving parts. Loose clothes, jewellery or
long hair can be caught in moving parts.
7. If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used. Use of
dust collection can reduce dust-related hazards.
8. Do not let familiarity gained from frequent use
of tools allow you to become complacent and
ignore tool safety principles. A careless action
can cause severe injury within a fraction of a
second.
9. Always wear protective goggles to protect
your eyes from injury when using power tools.
The goggles must comply with ANSI Z87.1 in
the USA, EN 166 in Europe, or AS/NZS 1336
in Australia/New Zealand. In Australia/New
Zealand, it is legally required to wear a face
shield to protect your face, too.
It is an employer's responsibility to enforce the
use of appropriate safety protective equipment
by the tool operators and by other persons in
the immediate working area.
4 ENGLISH
Power tool use and care
1. 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.
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
and/or remove the battery pack, if detachable,
from the power tool before making any adjustments, changing accessories, or storing power
tools. Such preventive safety measures reduce
the risk of starting the power tool accidentally.
4. Store idle power tools out of the reach of chil-
dren 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.
5. Maintain power tools and accessories. 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. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
7. Use the power tool, accessories and tool bits
etc. in accordance with these instructions, 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.
8. Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery
handles and grasping surfaces do not allow for
safe handling and control of the tool in unexpected
situations.
9. When using the tool, do not wear cloth work gloves which may be entangled. The entanglement of cloth work gloves in the moving parts may
result in personal injury.
Battery tool use and care
1. Recharge only with the charger specied by the manufacturer. A charger that is suitable for
one type of battery pack may create a risk of re
when used with another battery pack.
2. Use power tools only with specically desig-nated battery packs. Use of any other battery
packs may create a risk of injury and re.
3. When battery pack is not in use, keep it away
from other metal objects, like paper clips,
coins, keys, nails, screws or other small metal
objects, that can make a connection from one
terminal to another. Shorting the battery termi-
nals together may cause burns or a re.
4. Under abusive conditions, liquid may be
ejected from the battery; avoid contact. If con-
tact accidentally occurs, ush with water. If
liquid contacts eyes, additionally seek medical
help. Liquid ejected from the battery may cause
irritation or burns.
5. Do not use a battery pack or tool that is dam-
aged or modied. Damaged or modied batteries
may exhibit unpredictable behaviour resulting in
re, explosion or risk of injury.
6. Do not expose a battery pack or tool to re or excessive temperature. Exposure to re or tem-
perature above 130 °C may cause explosion.
7. Follow all charging instructions and do not
charge the battery pack or tool outside the
temperature range specied in the instructions. Charging improperly or at temperatures
outside the specied range may damage the
battery and increase the risk of re.
Service
1. Have your power tool serviced by a qualied
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
2. Never service damaged battery packs. Service
of battery packs should only be performed by the
manufacturer or authorized service providers.
3. Follow instruction for lubricating and chang-
ing accessories.
Safety instructions for mitre saws
1. Mitre saws are intended to cut wood or woodlike products, they cannot be used with abrasive cut-off wheels for cutting ferrous material
such as bars, rods, studs, etc. Abrasive dust
causes moving parts such as the lower guard to
jam. Sparks from abrasive cutting will burn the
lower guard, the kerf insert and other plastic parts.
2. Use clamps to support the workpiece when-
ever 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.
3. The workpiece must be stationary and
clamped or held against both the fence and the
table. 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. Push the saw through the workpiece. Do not
pull the saw through the workpiece. To make
a cut, raise the saw head and pull it out over
the workpiece without cutting, start the motor,
press the saw head down and push the saw
through the workpiece. Cutting on the pull stroke
is likely to cause the saw blade to climb on top
of the workpiece and violently throw the blade
assembly towards the operator.
5. 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 ENGLISH
6. 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 proxim-
ity of the spinning saw blade to your hand may not
be obvious and you may be seriously injured.
7. 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.
8. 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.
9.
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.
10. Ensure the mitre saw is mounted or placed on a level, rm work surface before use. A level
and rm work surface reduces the risk of the mitre
saw becoming unstable.
11. 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.
12. Provide adequate support such as table exten-
sions, 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.
13. 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.
14. The cut-off piece must not be jammed or
pressed by any means against the spinning
saw blade. If conned, i.e. using length stops, the
cut-off piece could get wedged against the blade
and thrown violently.
15. Always use a clamp or a xture 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.
16. Let the blade reach full speed before contact-ing the workpiece. This will reduce the risk of the
workpiece being thrown.
17. 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 and/or remove the battery
pack. Then work to free the jammed material.
Continued sawing with a jammed workpiece could
cause loss of control or damage to the mitre saw.
18. After nishing 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.
19. Hold the handle rmly when making an incom-
plete cut or when releasing the switch before
the saw head is completely in the down position. The braking action of the saw may cause
the saw head to be suddenly pulled downward,
causing a risk of injury.
20. Only use the saw blade with the diameter that
is marked on the tool or specied in the manual. Use of an incorrectly sized blade may affect
the proper guarding of the blade or guard opera-
tion which could result in serious personal injury.
21. Only use the saw blades that are marked with
a speed equal or higher than the speed marked
on the tool.
22. Do not use the saw to cut other than wood,
aluminum or similar materials.
23. (For European countries only)
Always use the blade which conforms to
EN847-1.
Additional instructions
1. Make workshop kid proof with padlocks.
2. Never stand on the tool. Serious injury could
occur if the tool is tipped or if the cutting tool is
unintentionally contacted.
3. Never leave the tool running unattended. Turn
the power off. Do not leave tool until it comes
to a complete stop.
4. Do not operate saw without guards in place.
Check blade guard for proper closing before
each use. Do not operate saw if blade guard
does not move freely and close instantly.
Never clamp or tie the blade guard into the
open position.
5. Keep hands out of path of saw blade. Avoid
contact with any coasting blade. It can still
cause severe injury.
6. To reduce the risk of injury, return carriage
to the full rear position after each crosscut
operation.
6 ENGLISH
7. Always secure all moving portions before
carrying the tool.
8. Stopper pin which locks the cutter head down
is for carrying and storage purposes only and
not for any cutting operations.
9. Check the blade carefully for cracks or dam-
age before operation. Replace cracked or damaged blade immediately. Gum and wood pitch
hardened on blades slows saw and increases
potential for kickback. Keep blade clean by
rst removing it from tool, then cleaning it with
gum and pitch remover, hot water or kerosene.
Never use gasoline to clean blade.
10. While making a slide cut, KICKBACK can
occur. KICKBACK occurs when the blade
binds in the workpiece during a cutting operation and the saw blade is driven rapidly
towards the operator. Loss of control and serious personal injury can result. If blade begins
to bind during a cutting operation, do not continue to cut and release switch immediately.
11. Use only anges specied for this tool.
12. Be careful not to damage the arbor, anges
(especially the installing surface) or bolt.
Damage to these parts could result in blade
breakage.
13. Make sure that the turn base is properly
secured so it will not move during operation.
Use the holes in the base to fasten the saw to a
stable work platform or bench. NEVER use tool
where operator positioning would be awkward.
14. Make sure the shaft lock is released before the
switch is turned on.
15. Be sure that the blade does not contact the
turn base in the lowest position.
16. Hold the handle rmly. Be aware that the saw
moves up or down slightly during start-up and
stopping.
17. Make sure the blade is not contacting the
workpiece before the switch is turned on.
18. Before using the tool on an actual workpiece,
let it run for a while. Watch for vibration or
wobbling that could indicate poor installation
or a poorly balanced blade.
19. Stop operation immediately if you notice any-
thing abnormal.
20. Do not attempt to lock the trigger in the "ON"
position.
21. Always use accessories recommended in this
manual. Use of improper accessories such as
abrasive wheels may cause an injury.
22. Some material contains chemicals which may
be toxic. Take caution to prevent dust inhalation and skin contact. Follow material supplier
safety data.
23. Do not use a corded power supply with this
tool.

Blade guard
1
► 1. Blade guard
When lowering the handle, the blade guard rises automatically. The guard is spring loaded so it returns to its original
position when the cut is completed and the handle is raised.
WARNING: Never defeat or remove the blade
guard or the spring which attaches to the guard.
An exposed blade as a result of defeated guarding
may result in serious personal injury during operation.
In the interest of your personal safety, always maintain
the blade guard in good condition. Any irregular operation of the blade guard should be corrected immediately.
Check to assure spring loaded return action of guard.
WARNING: Never use the tool if the blade
guard or spring are damaged, faulty or removed.
Operation of the tool with a damaged, faulty or
removed guard may result in serious personal injury.
If the see-through blade guard becomes dirty, or sawdust
adheres to it in such a way that the blade and/or workpiece is no longer easily visible, remove the batteries and
clean the guard carefully with a damp cloth. Do not use
solvents or any petroleum-based cleaners on the plastic
guard because this may cause damage to the guard.
If the blade guard is especially dirty and vision through the guard
is impaired, remove the batteries and use the supplied wrench to
loosen the hex bolt holding the center cover. Loosen the hex bolt
by turning it counterclockwise and raise the blade guard and center cover. With the blade guard so positioned, cleaning can be
more completely and efciently accomplished. When cleaning is
complete, reverse procedure above and secure the bolt. Do not
remove spring holding blade guard. If guard becomes discolored
through age or UV light exposure, contact a Makita service center for a new guard. DO NOT DEFEAT OR REMOVE GUARD.
