Cutting procedures
1 .
DANGER: Keep hands away from cutting area
and the blade. Keep your second hand on auxil-
iary handle, or motor housing. I f both h and s are
holding the saw, they cannot be cut by the blade.
2. Do not reach underneath the workpiece. T h e
guard cannot protect you from the blade below the
w orkpiec e.
3. Adjust the cutting depth to the thickness of
the workpiece. L ess th an a f ull tooth of th e blad e
teeth sh ould be v isible below th e w orkpiec e.
4 . Never hold the workpiece in your hands or
across your leg while cutting. Secure the
workpiece to a stable platform. I t is important to
support the work properly to minimise body expo-
sure, blad e bind ing, or loss of c ontrol.
 Fig.1
5 . Hold the power tool by insulated gripping
surfaces, when performing an operation where
the cutting tool may contact hidden wiring.
C ontac t w ith a “ liv e” w ire w ill also make ex posed
metal parts of th e pow er tool “ liv e” and c ould giv e
th e operator an elec tric sh oc k.
6 . W hen ripping, always use a rip fence or
straight edge guide. This improves the accuracy
of c ut and red uc es th e c h anc e of blad e bind ing.
7.
Always use blades with correct size and shape
(diamond versus round) of arbour holes. Blad es
th at d o not matc h th e mounting h ard w are of th e
saw w ill run of f -c entre, c ausing loss of c ontrol.
8 . Never use damaged or incorrect blade wash-
ers or bolt. T h e blad e w ash ers and bolt w ere
specially designed for your saw, for optimum
performance and safety of operation.
Kickback causes and related warnings
— kic kbac k is a sud d en reac tion to a pinc h ed ,
jammed or misaligned saw blade, causing an
unc ontrolled saw to lif t up and out of th e w orkpiec e
tow ard th e operator;
—
when the blade is pinched or jammed tightly by the
kerf c losing d ow n, th e blad e stalls and th e motor reac -
tion drives the unit rapidly back toward the operator;
— if th e blad e bec omes tw isted or misaligned in th e c ut,
th e teeth at th e bac k ed ge of th e blad e c an d ig into th e
top surf ac e of th e w ood c ausing th e blad e to c limb out
of the kerf and jump back toward the operator.
Kickback is the result of saw misuse and/or incorrect
operating proc ed ures or c ond itions and c an be av oid ed
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 prec autions are taken.
2.
W hen 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. I nv estigate and take c orrec -
tiv e ac tions to eliminate th e c ause of blad e bind ing.
3. W hen restarting a saw in the workpiece, centre
the saw blade in the kerf so that the saw teeth
are not engaged into the material. I f a saw blad e
binds, it may walk up or kickback from the work-
piec e as th e saw is restarted .
4 . Support large panels to minimise the risk of
blade pinching and kickback. L arge panels tend
to sag und er th eir ow n w eigh t. S upports must be
plac ed und er th e panel on both sid es, near th e line
of c ut and near th e ed ge of th e panel.
 Fig.2
 Fig.3
5 . Do not use dull or damaged blades.
Unsharpened or improperly set blades produce
narrow kerf c ausing ex c essiv e f ric tion, blad e
bind ing and kic kbac k.

12 ENGLISH
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
c ause bind ing and kic kbac k.
7. Use extra caution when sawing into existing
walls or other blind areas. T h e protrud ing blad e
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.
 Fig.4
9 .
Never force the saw. Push the saw forward at a speed so
that the blade cuts without slowing. F orc ing th e saw c an
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. R aise th e low er guard w ith th e retrac ting h and le
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. L ow er
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 mate-
rial, the lower guard must be released. F or all oth er
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. A n unprotec ted , c oasting blad e
w ill c ause th e saw to w alk bac kw ard s, c utting
w h atev er is in its path . Be aw are of th e time it
takes f or th e blad e to stop af ter sw itc h 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. L eav ing blad e ex posed
is VER Y D A NG ER O U S and c an lead to serious
personal injury.
Additional safety warnings
1 .
Use extra caution when cutting damp wood, pres-
sure treated lumber, or wood containing knots.
Maintain smooth ad v anc ement of tool w ith out d ec rease
in blad e speed to av oid ov erh eating th e blad e tips.
2. Do not attempt to remove cut material when
blade is moving. W ait until blade stops before
grasping cut material. Blad es c oast af ter turn of f .
3. Avoid cutting nails. Inspect for and remove all
nails from lumber before cutting.
4 . 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 off
when the cut is made. If the workpiece is short
or small, clamp it down. DO NOT TRY TO HOLD
SHORT PIECES BY HAND!
 Fig.5
5 . 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.
6 . Never attempt to saw with the circular saw
held upside down in a vise. This is extremely
dangerous and can lead to serious accidents.
 Fig.6
7.
Some material contains chemicals which may be
toxic. Take caution to prevent dust inhalation and
skin contact. Follow material supplier safety data.
8 . Do not stop the blades by lateral pressure on
the saw blade.
9 . Do not use any abrasive wheels.
1 0. 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 affect
th e proper guard ing of th e blad e or guard opera-
tion which could result in serious personal injury.
1 1 .
Keep blade sharp and clean. G um and w ood pitc h
h ard ened on blad es slow s saw and inc reases poten-
tial for kickback. Keep blade clean by rst removing
it f rom tool, th en c leaning it w ith gum and pitc h
remov er, h ot w ater or kerosene. Nev er use gasoline.
1 2. W ear a dust mask and hearing protection when
use the tool.
1 3. Always use the saw blade intended for cutting
the material that you are going to cut.
14.
Only use the saw blades that are marked with a speed
equal or higher than the speed marked on the tool.
15. (For European countries only)
Always use the blade which conforms to EN847-1.

If the lower guard is not functioning properly, check if
saw d ust is ac c umulated insid e of th e upper and low er
guards. If the lower guard is not functioning properly
even after removing dust, have your tool serviced at a
Makita serv ic e c enter.
Cutting operation
CAUTION: W ear dust mask when performing
cutting operation.
CAUTION: Be sure to move the tool forward
in a straight line gently. F orc ing or tw isting th e tool
w ill result in ov erh eating th e motor and d angerous
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. T h en, th e tool c an w ork to its
full capacity.
 Fig.30
old the tool rmly. The tool is provided with both a front grip
and rear h and le. U se both to best grasp th e tool. I f both h and s
are holding saw, they cannot be cut by the circular saw blade.
S et th e base on th e w orkpiec e to be c ut w ith out th e c irc ular

until the circular saw blade attains full speed. Now simply
mov e th e tool f orw ard ov er th e w orkpiec e surf ac e, 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 properly 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 blad e and lead to d angerous kic kbac k and possible
serious injury. Release switch, wait for circular saw blade
to stop and th en w ith d raw tool. R ealign tool on new c ut
line, and start c ut again.A ttempt to av oid positioning w h ic h
exposes operator to chips and wood dust being ejected
from saw. Use eye protection to help avoid injury.
