SAFETY WARNINGS
General power tool safety warnings
WARNING: Read all safety warnings, instruc-
tions, illustrations and specications 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 instruc-
tions 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. Unmodied 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 ground fault circuit inter-
rupter (GFCI) protected supply. Use of a GFCI
reduces the risk of electric shock.

3ENGLISH
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 inuence 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 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 o󰀨-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, clothing and gloves
away from moving parts. Loose clothes, jewel-
lery 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 gog-
gles must comply with ANSI Z87.1 in the USA.
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.
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 o󰀨. 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 adjust-
ments, 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 a󰀨ect 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 di󰀨erent
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 grasp-
ing 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 entangle-
ment of cloth work gloves in the moving parts may
result in personal injury.
Battery tool use and care
1. Recharge only with the charger specied 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 specically 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 contact acciden-
tally 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 modied. Damaged or modied 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 specied in the instruc-
tions. Charging improperly or at temperatures
outside the specied range may damage the
battery and increase the risk of re.
Service
1. Have your power tool serviced by a qualied
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.

4ENGLISH
3. Follow instruction for lubricating and chang-
ing accessories.
4. Do not modify or attempt to repair the appli-
ance or the battery pack except as indicated in
the instructions for use and care.
Cordless circular saw safety
warnings
Cutting procedures
1. DANGER:
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.
2. Do not reach underneath the workpiece. The
guard cannot protect you from the blade below the
workpiece.
3. 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.
4. Never hold the workpiece in your hands or
across your leg while cutting. Secure the
workpiece to a stable platform. It is important to
support the work properly to minimise body expo-
sure, blade binding, or loss of control.
5. Hold the power tool by insulated gripping
surfaces, when performing an operation where
the cutting tool may contact hidden wiring.
Contact with a "live" wire will also make exposed
metal parts of the power tool "live" and could give
the operator an electric shock.
6. When ripping, always use a rip fence or
straight edge guide. This improves the accuracy
of cut and reduces the chance of blade binding.
7.
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
o󰀨-centre, causing loss of control.
8. Never use damaged or incorrect blade wash-
ers or bolt. The blade washers and bolt were
specially designed for your saw, for optimum
performance and safety of operation.
Kickback causes and related warnings
— kickback is a sudden reaction to a pinched,
jammed or misaligned saw blade, causing an
uncontrolled saw to lift up and out of the workpiece
toward the operator;
—
when the blade is pinched or jammed 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.
1. Maintain a rm 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.
2. 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.
3. When restarting a saw in the workpiece, centre
the saw blade in the kerf so that the saw teeth
are not engaged into the material. If a saw blade
binds, it may walk up or kickback from the work-
piece as the saw is restarted.
4. 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.
5. Do not use dull or damaged blades.
Unsharpened or improperly set blades produce
narrow kerf causing excessive friction, blade
binding and kickback.

5ENGLISH
6. Blade depth and bevel adjusting locking levers
must be tight and secure before making the
cut. If blade adjustment shifts while cutting, it may
cause binding and kickback.
7. Use extra caution when sawing into existing
walls or other blind areas. The protruding blade
may cut objects that can cause kickback.
8. ALWAYS hold the tool rmly with both hands.
NEVER place your hand, leg or any part of your
body under the tool base or behind the saw,
especially when making cross-cuts. If kickback
occurs, the saw could easily jump backwards over
your hand, leading to serious personal injury.
9. Never force the saw. Push the saw forward at a
speed so that the blade cuts without slowing.
Forcing the saw can cause uneven cuts, loss of
accuracy, and possible kickback.
Lower guard function
1. Check the lower guard for proper closing
before each use. Do not operate the saw if the
lower guard does not move freely and close
instantly. Never clamp or tie the lower guard
into the open position. If the saw is accidentally
dropped, the 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.
2.
Check the operation of the lower guard spring. If
the guard and the spring are not operating prop-
erly, they must be serviced before use. Lower
guard may operate sluggishly due to damaged
parts, gummy deposits, or a build-up of debris.
3. The lower guard may be retracted manually
only for special cuts such as “plunge cuts”
and “compound cuts”. Raise the lower guard
by the retracting handle and as soon as the
blade enters the material, the lower guard
must be released. For all other sawing, the lower
guard should operate automatically.
4. Always observe that the lower guard is cover-
ing the blade before placing the saw down on
bench or oor. 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.
5. To check lower guard, open lower guard by
hand, then release and watch guard closure.
Also check to see that retracting handle does
not touch tool housing. Leaving blade exposed
is VERY DANGEROUS and can lead to serious
personal injury.
Additional safety warnings
1. Intended use
This tool is intended to cut wood products by
lengthways and crossways straight cuts and
miter cuts with angles while in rm contact
with the workpiece.
With appropriate Makita genuine circular saw
blades, other materials can also be sawed.
Accumulated sawdust on the lower guard and hub
from other materials may e󰀨ect the proper closure
of the lower guard which could lead to serious
personal injury.
2. Use extra caution when cutting damp wood,
pressure treated lumber, or wood containing
knots. Maintain smooth advancement of tool with-
out decrease in blade speed to avoid overheating
the blade tips.
3. Do not attempt to remove cut material when
blade is moving. Wait until blade stops before
grasping cut material. Blades coast after turn o󰀨.
4. Avoid cutting nails. Inspect for and remove all
nails from lumber before cutting.
5. Place the wider portion of the saw base on
that part of the workpiece which is solidly
supported, not on the section that will fall o󰀨
when the cut is made. If the workpiece is short
or small, clamp it down. DO NOT TRY TO HOLD
SHORT PIECES BY HAND!
6. Before setting the tool down after completing a
cut, be sure that the guard has closed and the
blade has come to a complete stop.
7. Never attempt to saw with the circular saw
held upside down in a vise. This is extremely
dangerous and can lead to serious accidents.

6ENGLISH
8. Some material contains chemicals which may be toxic.
Take caution to prevent dust inhalation and skin con-
tact. Follow material supplier safety data.
9. Do not stop the blades by lateral pressure on
the saw blade.
10. Do not use any abrasive wheels.
11. Only use the saw blade with the diameter that
is marked on the tool or specied in the man-
ual. Use of an incorrectly sized blade may a󰀨ect
the proper guarding of the blade or guard opera-
tion which could result in serious personal injury.
12.
Keep blade sharp and clean. 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.
13. Wear a dust mask and hearing protection when
use the tool.
14. Always use the saw blade intended for cutting
the material that you are going to cut.
15.
Only use the saw blades that are marked with a speed
equal or higher than the speed marked on the tool.
16. Place the tool and the parts on a at and stable
surface. Otherwise the tool or the parts may fall
and cause an injury.

possible loss of control during operation and in seri-
ous personal injury.
Blade guard cleaning
When changing the circular saw blade, make sure to
also clean the upper and lower blade guards of accu-
mulated sawdust as discussed in the Maintenance
section. Such e󰀨orts do not replace the need to check
lower guard operation before each use.

priate Makita genuine circular saw blades, following
materials can also be sawed:
• Aluminum products
Refer to our website or contact your local Makita dealer
for the correct circular saw blades to be used for the
material to be cut.
Checking blade guard function
Set the bevel angle to 0°, and then retract the lower
guard manually to the end and release it. The lower
guard is properly functioning if;
— it is retracted above the base without any hin-
drance and;
— it automatically returns and contacts with the

Cutting operation
CAUTION: Wear dust mask when performing
cutting operation.
CAUTION: Be sure to move the tool forward
in a straight line gently. Forcing or twisting the tool
will result in overheating the motor and dangerous
kickback, possibly causing severe injury.
NOTE: When the battery cartridge temperature is
low, the tool may not work to its full capacity. At this
time, for example, use the tool for a light-duty cut for
a while until the battery cartridge warms up as high
as room temperature. Then, the tool can work to its
full capacity.
Hold the tool rmly. The tool is provided with both a front
grip and rear handle. Use both to best grasp the tool.
If both hands are holding saw, they cannot be cut by
the circular saw blade. Set the base on the workpiece
to be cut without the circular saw blade making any
contact. Then turn the tool on and wait until the circular
saw blade attains full speed. Now simply move the tool
forward over the workpiece surface, keeping it at and
advancing smoothly until the sawing is completed.
To get clean cuts, keep your sawing line straight and
your speed of advance uniform. If the cut fails to prop-
erly follow your intended cut line, do not attempt to turn
or force the tool back to the cut line. Doing so may bind
the circular saw blade and lead to dangerous kickback
and possible serious injury. Release switch, wait for cir-
cular saw blade to stop and then withdraw tool. Realign
tool on new cut line, and start cut again. Attempt to
avoid positioning which exposes operator to chips and
wood dust being ejected from saw. Use eye protection
to help avoid injury.
Rip fence (Guide rule)
CAUTION: Make sure that the rip fence is
securely installed in the correct position before
use. Improper attachment may cause dangerous
kickback.
1
2
► 1. Rip fence (Guide rule) 2. Clamping screw
The handy rip fence allows you to do extra-accurate
straight cuts. Simply slide the rip fence up snugly
against the side of the workpiece and secure it in posi-
tion with the clamping screw on the front of the base. It
also makes repeated cuts of uniform width possible.
Guide rail
Optional accessory
Place the tool on the rear end of guide rail. Turn two
adjusting screws on the tool base so that the tool slides
smoothly without a clatter. Hold both the front grip and
rear handle of the tool rmly. Turn on the tool and cut
the splinter-guard along the full length with a stroke.
Now the edge of the splinter-guard corresponds to the
cutting edge.
1
► 1. Adjusting screws
When bevel cutting with the guide rail, use the slide
lever to prevent the tool from falling over.
Move the slide lever on the tool base in the direction
of arrow so that it engages the undercut groove in the
guide rail.
