 Work area safety

Ke ep work area clean and well lit.

Cluttered or dark areas invite accidents.

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.

Keep children and bystanders away while
operating a power tool. Distractions can

cause you to lose control.

 Electrical safety

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.

Avoid body contact with earthed or
grounded su rfaces, such as pipes,
radiators, ranges and refrigerators. There

is an increased risk of electric shock if
your body is earthed or grounded.

Do not expose power tools to rain or wet
conditions. Water entering a power tool

will increase the risk of electric shock.

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.

When operating a power tool outdoors,
us e an exten sion cord suitable for
outdoor use. Use of a cord suitable for

outdoor use reduces the risk of electric
shock.

If operating a power tool in a damp
location is unavoidable, use a Ground
Fa ult Circuit In terrupte r ( GFCI)
protected supply. Use of an GFCI reduces

the risk of electric shock.

 Personal safety

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

Read all safety warnings, instructions, illustrations and specifications
provided with this power tool. Failure to follow all instructions listed

below may result in electric shock, fire and/or serious injury.

SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE

General Power Tool Safety Warnings

of drugs, alcohol or medication. A moment
of inattention while operating power tools
may result in serious personal injury.

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.

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 finger

on the switch or energizing power tools
that have the switch on invites accidents.

Remove any adjusting key or wrench
before turning the power tool on. A

wrench or a key left attached to a rotating
pa rt o f the power tool may result in
personal injury.

Do not overreach. Keep proper footing
and balance at all times. This enables

be t ter control of the po wer tool in
unexpected situations.

Dr ess proper ly. Do not we ar loose
clothing or jewelry. Keep your hair,
clothing and gloves away from moving
parts. Loose clothes, jewelry or long hair

can be caught in moving parts.

If devic es ar e prov ided for the
co nnection of dust extractio n and
collection facilities, ensure these are
connected and properly used. Use of dust

co l lection can red uce dust-re lated
hazards.

Do not let familiar ity gain ed from
fr equent use of tools allow yo u to
become complacent and ignore tool
safety principles. A careless action can

cause severe injury within a fraction of a
second.

 Power tool use and care

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.

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.

Disconnect the plug from the power
source and/or remove the battery pack, if
detachable, from the power tool before
making any adjustments, chang ing
accessories, or storing power tools. Such

preventive safety measures reduce the risk
of starting the power tool accidentally.

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.

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.

Keep cutting tools sharp and clean.

Properly maintained cutting tools with
sharp cutting edges are less likely to bind
and are easier to control.

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.

Keep handles and grasping surfaces dry,
cl ean and f ree from oil and grease.

Slippery handles and grasping surfaces do
not allow for safe handling and control of
the tool in unexpected situations.

 Battery tool use and care

Recharge only wi t h the charger
specified by the manufacturer. A charger

that is suitable for one type of battery
pack may create a risk of fire when used
with another battery pack.

Use power tools only with specifically
designated battery packs. Use of any

other battery packs may create a risk of
injury and fire.

When battery pack is not in use, keep it
aw ay fro m othe r meta l obje cts li ke
paper clips, coins, keys, nails, screws,

or other small metal objects that can
make a connection from one terminal to
another. Shorting the battery terminals

together may cause burns or a fire.

Under abusive conditions, liquid may be
ejected from the battery, avoid contact.
If contact accidentally occurs, flush with
water. If l i q u i d contacts eyes,
additionally seek medical help. Liquid

eject e d from the battery may cause
irritation or burns.

Do not use a battery pack or tool that is
damaged or modified. Damaged or modified

batt e r i e s may e x h ibit unpre d i c t a b l e
behaviour resulting in fire, explosion or risk
of injury.

Do not expose a battery pack or tool to
fire or excessive temperature. Exposure

to fire or temperature above 265 °F may
cause explosion.

Follow all charging instructions and do
not charge the battery pack or tool

outside the temperature range specified
in the instructions. Charging improperly

or at temperatures outside the specified
range may damage th e battery and
increase the risk of fire.

 Service

Have your power tool serviced by a
qualified re pair p erson using only
identical replacement parts. This will

ensure that the safety of the power tool is
maintained.

Never service damaged battery packs.

Service of battery packs should only be
pe r formed by the manufac turer or
authorized service providers.

 Cutting procedures

Keep hands away from

cutt i n g ar e a 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.

Do not reach underneath the workpiece.

The guard cannot protect you from the
blade below the workpiece.

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.

Never hold the workpiece in your hands or
across your leg while cutting. Secure the
work p i e c e to a st a b l e platform. It is

important to support the work properly to
minimize body exposure, blade binding, or
loss of control.

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
“liv e ” and could g i v e the opera t o r an
electric shock.

When ripping, always use a rip fence or

straight edge guide. This improve s the

accuracy of cut and reduces the chance of
blade binding.

Always use blades with correct size and
shape (diamond versus round) of arbor
hole s . Blad e s that do not m a t c h the

mounting hardware of the saw will run off­center, causing loss of control.

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.

 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.

Wh en th e bla de is pinc hed o r ja m med
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

Safety Instructions for Circular Saws

2610052972.qxp_CCS180 8/6/19 12:50 PM Page 4

kerf and jump back toward the operator.
Kickback is the result of tool misuse and/or

inco r r e c t o p e r a t ing p rocedures or
conditions and can be avoided by taking
proper precautions as given below:

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.

When bla d e is bi n d i n g , o r w h e n
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 action to eliminate the cause of
blade binding.

When restarting a saw in the workpiece,
center 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 workpiece as the
saw is restarted.

Support large panels to minimize 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.

Do not us e dull or da m a g ed blad e s .

Un sharp ened or i mprop erly set blades
produ ce narrow kerf caus ing excessive
friction, blade binding and kickback.

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.

Use extra caution wh e n sawing into
existing walls or other blind areas. The

protruding blade may cut objects that can
cause kickback.

 Lower Guard Function

Ch eck lowe r guard for pro per clos ing
before each use. Do not operate saw if
lower guard does not move freely and
close instantly. Never clamp or tie the
lower guard into the open position. If the

saw is acciden tally 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.

Check the operation of the lower guard
spring. If the guard and the spring are not
operating properly, they must be serviced
bef o re use . L ower g u ard ma y opera t e

sluggishly due to damaged parts, gummy
deposits, or a build-up of debris.

The l o w e r g u a rd 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 enter s th e
mate r i a l , the lower gu a r d must be
released. For all other sawing, the lower

guard should operate automatically.

Always observe that the guard is covering
the blade before placing the 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
the switch is released.

This product is intended to cut wood and
wood-like products only. Dust build up

around the lower guard and hub from other
materials (plastic, masonry or metal) may
disable the lower guard operation.

Inspect the condition and quality of the
wood and remove all nails from lumber
before cutting. Wet lumber, green lumber

or pressure treated lumber require special
atte n t i o n du ring cutting operation to
prevent kickback.

Hold the saw firmly to prevent loss of
control. Figures in this manual illustrate

typical hand support of the saw.

Depending upon use, the switch may not
la st the li fe o f the saw . If the swit ch
should fail in the “OFF” position, the saw
may not start. If it should fail while the
saw is running, the saw may not shut off. If

either occurs, unplug the saw immediately
and do not use until repaired.

This circular saw should not be mounted

to a table and converted to a table saw.

Circular saws are not designed or intended
to be used as table saws.

The blade washers and the bolt on your
sa w have been des igned to wor k as a
clut c h to reduce the i n t ensity of a
kickback. Understand the operation and
settings of the VARI-TORQUE CLUTCH. The

proper setting of the clutch, combined with
firm handling of the saw will allow you to
control kickback.

Never place your hand behind the saw
blade. Kickback could cause the saw to

jump backwards over your hand.

Do not use the saw with an excessive
dep t h of cut s e tting. Too much blade

exposure increases the likelihood of the
blade twisting in the kerf and increases the
su rface are a of the blade availab le f or
pinching that leads to kickback.

Do not run the tool while carrying it at
your side. Lower guard may be opened by
a contact with your clothing. Accidental

contact with the spinning saw blade could
result in serious personal injury.

Periodically remove the blade, clean the
upper, lower guards and the hub area with
kero s e n e and wi p e it dry. Prevent i v e

maintenance and properly operating guard
will reduce the probability of an accident.

Ensure the switch is in the off position
before inserting battery pack. Inserting the

battery pack into power tools that have the
switch on invites accidents.

Avoid overheating saw blade tips.

Additional Safety Warnings

GFCI and personal protection devices like
electrician’s rubber gloves and footwear will
further enhance your personal safety.

Do not use AC only rated tools with a DC
power supply. While the tool may appear to

work, the electrical components of the AC
rated tool are likely to fail and create a
hazard to the operator.

Keep handles dry, clean and free from oil
and grease. Slippery hands cannot safely

control the power tool.

Develop a periodic maintenance schedule
for your tool. When cleaning a tool be
careful not to disassemble any portion of
the to ol since intern a l wires may be
mi splac ed o r pinched or saf ety guard
retu r n sp r ings may be i m p r o p erly
mounted. Certain cleaning agents such as

gasoline, carbon tetrachloride, ammonia,
etc. may damage plastic parts.

STUD is properly tightened (as
described in No. 5 of Attaching The
Blad e ) , the b l a d e will s l i p when i t
encounters ex cessive resistance, thus
reducing saw’s tendency to KICKBACK.

One setting may not be sufficient for
cutting all materials. If ex cessive blade
slippage occurs, tighten the blade stud
one mark more. OVERTIGHTENING THE
BLAD E ST U D NULLIFIES THE
EFFECTIVENESS OF THE CLUTCH.

 Dust Extraction

pack from tool
befo r e makin g any assembly,
adjustments or changing accessories.

Such preventive safety measures reduce
the risk of starting the tool accidentally.

 Depth Adjustment

Di sconne ct ba ttery pack fro m too l.
Lo osen the d epth adjus tment leve r
located on the right side of the tool.
Hold the foot down with one hand and
raise or lower saw by the handle.

Tigh t e n le v e r at the depth setting
desired. Check desired depth (Fig. 4).

Not more than one tooth length of the
blade should extend below the material
to be cut, for minimum splintering (Fig.

5).

 90° Cutting Angle Check

Disconnect battery pack from tool. Set
foot to maximum depth of cut setting.
Loosen bevel adjustment lever, set to 0°
on quadrant, retighten lever and check
for 90° angle between the blade and
bottom plane of foot with a square (Fig.

6). Make adjustments by turning the
small alignment screw from bottom side
of foot, if necessary (Fig. 7).

 Bevel Adjustment

Disconnect battery pack from tool. The
foot can be adjust e d up to 50° by
loosening the bevel adjustment knob at
the front of the saw. Align to desired
an gle on c alibr ated qua drant. Then
tighten bevel adjustment knob (Fig. 8).

Because of the increased amount of
bla d e enga g ement i n the work and
decreased stability of the foot, blade
binding may occur. Keep the saw steady
and the foot firmly on the workpiece.

 Line Guide

For a straight 90° cut, use left side of
notch in the foot. For 45° and 50° bevel
cuts, use the right side (Fig. 9). The
cutt i n g g u i d e notch will give an
approximate line of cut. Make sample
cuts in scrap lumber to verify actual line
of cut. This will be helpful because of
the number of different blade types and

thic k n e s s e s available. T o e n s ure
minimum splintering on the good side of
the material to be cut, face the good
side down.

 Safety Switch

The safety switch is designed to prevent
accident al starts. To operate safety
switch, press the release button with
your thumb on either side of handle to
disengage the lock, then pull the trigger
(Fig. 10). When the trigger is released
the button will engage the safety switch
automatically, and the trigger will no
longer oper ate. (See “SWITCH” and
“REGULAR CUTS”)

 Switch

When starting the tool, hold it with
both hands. The torque from the motor

can cause the tool to twist.
To turn tool on, press the safety switch

re lease butto n wit h you r thu mb o n
either side of handle to disengage the
lock, then pull the trigger (Fig. 10). To
turn the tool “OFF”, release the trigger
switch, which is spring loaded and will
return to the off position automatically.

Your saw should be running at full speed
BEFORE starting the cut, and turned off
onl y AFTER compl e t ing th e cut. To
increase switch life, do not turn switch
on and off while cutting.

 Brake

When the trigger is released it activates
the electrical brake to stop the blade
quickly. This feature is especially useful
when making repetitive cuts.

 Regular Cuts

Always hold the saw handle with one
hand and the auxiliary handle or housing
with the other.

Always make sure saw foot rests on
portion of work surface that does not
drop off.

Alwa y s be sure

either hand does not
interfere with the free movement of
the lower guard.

Maintain a firm grip and operate the

switch with a decisive action. Never
force the saw. Use light and continuous
pressure.

After complet ing a

cut and the trigger
has been released, be aware of the
nec es sary time it takes for the blade to
come to a com plete stop during coast
down. Do not allow the saw to brush
agains t yo ur leg or s ide, sin ce the
lower guard is retractable, it could
catch on your clothing and expose the
blade. Be aware of the necessary blade
ex posures that exist in both the upper
and lower guard areas.

When cutting is interrupted, to resume
cutting: squeeze the trigger and allow
the blade to reach full speed, re-enter
the cut slowly and resume cutting.

When cutting across the grain, the fibers
of the wood have a ten den cy to tear and
lift. Advancing the saw slowly minimizes
this effect. For a finished cut, a cross
cut blade or m i ter bla d e is r e c om ­mended.

 Cutting Masonry/Metal

This tool is not recommended for usage
with metal or masonry cut-off wheels.

Do not cut metal or
maso n r y with this

circular saw. The dust from metal or

masonry cutting will cause the lower
guard to become sluggish and may not
close fully and quickly after cutting
these materials.

Do not use abrasive
wheels with circular

saws. Abrasive dust may cause lower

guard to fail.

Do not use Wet

Diamond cutting off
wheel or water feed devices with this
circular saw. Masonry cutting waste will

enter the lower guard system, harden
and cause the guard to become
inoperable. Use of water in masonry
cutting applications with an electric
circular saw will cause electric shock
hazards.

 Plunge Cuts

Disc o n n e c t battery pack from tool
before making ad justments. Set depth
adjustment according to material to be
cut. Reattach battery pack to the saw.
Tilt saw forward with c utti ng guide
no tch lined up wit h th e li ne y ou’ve
drawn. Raise the lower guard, using lift
lever and hold the saw by the front and
rear handles (Fig. 11).

With the blade just clearing the material
to be cut, start the motor. Gradually
lower the back end of saw using the
front end of the foot as the hinge point.

As blade starts

cutting the ma terial,
release the lower guard immediately.

When the foot rests flat on the surface
being cut, proceed cutting in forward
direction to end of cut.

Allow blade to come

to a complete stop
before lifting the saw from cut. Also,
never pull the saw backward since
blade will climb out of the material and
KICKBACK will occur. Turn saw around

and finish the cut in the normal manner,
sawi n g forward. I f corners of your
pock e t cut are not comple t e l y cut
through, use a jigsaw or hand saw to
finish the corners.

 Cutting Large Sheets

Large sheets and long boards sag or
bend, depending on suppor t. If you
attempt to cut without leveling and
properly supporting the piece, the blade
will tend to bind, causing KICK-BACK
and extra load on the motor (Fig. 12).

Support the panel or board close to the
cut, as shown in (Fig. 13). Be sure to set
the depth of the cut so that you cut
through the sheet or board only and not
the table or work bench. The two-by­fours used to raise and support the
work should be positioned so that the
broadest sides support the work and
res t on the t a ble o r bench . Do not
support the work with the narrow sides
as this is an unsteady arrangement. If
the sheet or board to be cut is too large
for a t able o r work bench, use th e
supporting two-by-fours on the floor and
secure.

 Rip Cuts

The combination blade provided with
your saw is for both cross cuts and rip
cuts. Ripping is cutting lengthwise with
the grain of the wood. Narrow rip cuts
are easy to do with a rip fence (Fig. 14).
To attach optional rip f ence, in sert
fence through slots in foot to desired
width as shown and secure with the
knob.

Afte r at t a c h ing or

adju s t i n g th e ri p

move m e n t of the lower gu a r d o r
contact the saw blade.

 Rip Board Guide

When rip cutting large sheets, the rip
fence may not allow the desired width
of cut. Clamp or nail a straight piece of
1" (25 mm) lumber to the sheet as a
guide (Fig. 15). Use the right side of the
foot against the board guide.

Accessories and Attachments

Maintenance

 Bearings

Bearings which become noisy (due to
heavy load or very abrasive material
cutting) should be replaced at once to
avoid overheating and motor failure.

 Cleaning

Cert a i n cleaning

agents and solvents

damage plastic parts. Some of these

are: gasoline, car bo n tetrachlor ide,
chlorinated cleaning solvents, ammonia
and household detergents that contain
ammonia.

Ventilation openings and switch levers
must be kept clean and free of foreign
ma tter . Do not at tempt to clean by
inse r t i n g pointed objects t h r o u gh
opening.

Periodically remove the blade, clean
the upper, lower guards and the hub

area with kerosene and wipe it dry.

Preventive maintenance and properly
oper a t i n g g uard will reduce t h e
probability of an accident.

 Care of Blades

Blades become dull even from cutting
re gular lum ber. If you fin d yo ursel f
forcing the saw forward to cut instead
of just gu i d i n g it through the cut,
chances are the blade is dull or coated
with wood pitch.

When clean ing gum a nd wood p itch
from blade, remove the battery from the
saw and remove the blade. Remember,
blades are designed to cut, so handle
carefully. Wipe the blade with kerosene
or similar solvent to remove the gum
and pitch. Unless you are experienced in
sharpening blades, we recommend you
do not try.

The use of any other attachments or acces so ries not specified in

this manual may create a hazard.

Store accessories in a dry and temperate environment to avoid corrosion and
deterioration.
