PRODUCT SAFETY
GENERAL SAFETY
WARNINGS
WARNING Read all safety warnings, instructions,
illustrations and specications 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.
The term “power tool” in the warnings refers to your
mains-operated (corded) power tool or battery-operated
(cordless) power tool.
1) Work area safety
a) Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
b) Do not operate power tools in explosive
atmospheres, such as in the presence of
ammable liquids, gases or dust. Power tools
create sparks which may ignite the dust or fumes.
c) Keep children and bystanders away while
operating a power tool. Distractions can cause you
to lose control.
2) Electrical safety
a) 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.
b) Avoid body contact with earthed or grounded
surfaces, such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
c) Do not expose power tools to rain or wet
conditions. Water entering a power tool will increase
the risk of electric shock.
d) 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.
e) 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.
f) 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.
3) Personal safety
a) 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.
b) 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.
c) 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 energising power tools that have the switch
on invites accidents.
d) 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.
e) Do not overreach. Keep proper footing and balance
at all times. This enables better control of the power
tool in unexpected situations.
f) 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.
g) 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.
h) 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.
4) Power tool use and care
a) 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.
b) 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.
c) 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.
d) 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.
e) 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.
f) Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
g) 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

10
EN20V Cordless Brushless Circular saw
hazardous situation.
h) 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.
5) Battery tool use and care
a) 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 fire when used
with another battery pack.
b) Use power tools only with specically designated
battery packs. Use of any other battery packs may
create a risk of injury and fire.
c) 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 terminals together may cause
burns or a fire.
d) Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact
accidentally occurs, ush with water. If liquid
contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause irritation
or burns.
e) Do not use a battery pack or tool that is damaged
or modied. Damaged or modified batteries may
exhibit unpredictable behaviour resulting in fire,
explosion or risk of injury.
f) Do not expose a battery pack or tool to re
or excessive temperature. Exposure to fire or
temperature above 130 °C may cause explosion.
g) Follow all charging instructions and do not charge
the battery pack or tool outside the temperature
range specied in the instructions. Charging
improperly or at temperatures outside the specified
range may damage the battery and increase the risk
of fire.
6) Service
a) 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.
b) Never service damaged battery packs. Service
of battery packs should only be performed by the
manufacturer or authorized service providers.
SAFETY INSTRUCTIONS
FOR ALL SAWS
CUTTING PROCEDURES
a) DANGER: Keep hands away from cutting area
and the blade. If both hands are holding
the saw, they cannot be cut by the blade.
b) Do not reach underneath the workpiece. The
guard cannot protect you from the blade below the
workpiece.
c) 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.
d) 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 exposure, blade binding, or
loss of control.
e) 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.
f) When ripping, always use a rip fence or straight
edge guide. This improves the accuracy of cut and
reduces the chance of blade binding.
g) 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 off-centre, causing loss of control.
h) 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.
FURTHER SAFETY
INSTRUCTIONS FOR ALL
SAWS
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.
a) Maintain a rm grip 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.
b) 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.
c) 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 workpiece as the
saw is restarted.

11
EN20V Cordless Brushless Circular saw
d) 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.
e) Do not use dull or damaged blades. Unsharpened
or improperly set blades produce narrow kerf causing
excessive friction, blade binding and kickback.
f) 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.
g) Use extra caution when sawing into existing walls
or other blind areas. The protruding blade may cut
objects that can cause kickback.
SAFETY INSTRUCTIONS
FOR CIRCULAR SAW WITH
INNER PENDULUM GUARD
Lower guard function
a) 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.
b) Check the operation of the lower guard spring.
If the guard and the spring are not operating
properly, they must be serviced before use. Lower
guard may operate sluggishly due to damaged
parts, gummy deposits, or a build-up of debris.
c) The lower guard may be retracted manually
only for special cuts such as “plunge cuts”
and “compound cuts.” Raise the lower guard by
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.
d) Always observe that the lower guard is covering
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.
ADDITIONAL SAFETY
RULES FOR YOUR
CIRCULAR SAW
1. Use only saw blades recommended by the
manufacturer, which conform to EN 847-1, if
intended for wood and analogous materials.
2. Do not use any abrasive wheels.
3. Use only blade diameter(s) in accordance with the
markings.
4. Identify the correct saw blade to be used for the
material to be cut.
5. Use only saw blades that are marked with a speed
equal or higher than the speed marked on the tool.
CUT-OFF MACHINE SAFETY
WARNINGS
a) The guard provided with the tool must be securely
attached to the power tool and positioned for
maximum safety, so the least amount of wheel is
exposed towards the operator. Position yourself
and bystanders away from the plane of the
rotating wheel. The guard helps to protect operator
from broken wheel fragments and accidental
contact with wheel.
b) Use only bonded reinforced or diamond cut-off
wheels for your power tool. Just because an
accessory can be attached to your power tool, it
does not assure safe operation.
c) The rated speed of the accessory must be at
least equal to the maximum speed marked on the
power tool. Accessories running faster than their
rated speed can break and fly apart.
d) Wheels must be used only for recommended
applications. For example: do not grind with the
side of cut-off wheel. Abrasive cut-off wheels are
intended for peripheral grinding, side forces applied
to these wheels may cause them to shatter.
e) Always use undamaged wheel anges that are of
correct diameter for your selected wheel. Proper
wheel flanges support the wheel thus reducing the
possibility of wheel breakage.
f) Do not use worn down reinforced wheels from
larger power tools. Wheels intended for a larger
power tool are not suitable for the higher speed of a
smaller tool and may burst.
g) The outside diameter and the thickness of your
accessory must be within the capacity rating of
your power tool. Incorrectly sized accessories
cannot be adequately guarded or controlled.
h) The arbour size of wheels and anges must
properly t the spindle of the power tool. Wheels
and flanges with arbour holes that do not match the
mounting hardware of the power tool will run out of
balance, vibrate excessively and may cause loss of
control.
i) Do not use damaged wheels. Before each use,
inspect the wheels for chips and cracks. If power
tool or wheel is dropped, inspect for damage or
install an undamaged wheel. After inspecting
and installing the wheel, position yourself and
bystanders away from the plane of the rotating
wheel and run the power tool at maximum no
load speed for one minute. Damaged wheels will
normally break apart during this test time.
j) Wear personal protective equipment. Depending
on application, use face shield, safety goggles
or safety glasses. As appropriate, wear dust
mask, hearing protectors, gloves and shop apron
capable of stopping small abrasive or workpiece
fragments. The eye protection must be capable
of stopping flying debris generated by various

12
EN20V Cordless Brushless Circular saw
operations. The dust mask or respirator must be
capable of filtrating particles generated by your
operation. Prolonged exposure to high intensity
noise may cause hearing loss.
k) Keep bystanders a safe distance away from work
area. Anyone entering the work area must wear
personal protective equipment. Fragments of
workpiece or of a broken wheel may fly away and
cause injury beyond immediate area of operation.
l) Hold the power tool by insulated gripping
surfaces only, when performing an operation
where the cutting accessory may contact hidden
wiring. Cutting accessory contacting a “live” wire
may make exposed metal parts of the power tool
“live” and could give the operator an electric shock.
m) Never lay the power tool down until the accessory
has come to a complete stop. The spinning wheel
may grab the surface and pull the power tool out of
your control.
n) Do not run the power tool while carrying it at
your side. Accidental contact with the spinning
accessory could snag your clothing, pulling the
accessory into your body.
o) Regularly clean the power tool’s air vents. The
motor’s fan will draw the dust inside the housing
and excessive accumulation of powdered metal
may cause electrical hazards.
p) Do not operate the power tool near ammable
materials. Sparks could ignite these materials.
KICKBACK AND RELATED
WARNINGS
Kickback is a sudden reaction to a pinched or snagged
rotating wheel. Pinching or snagging causes rapid
stalling of the rotating wheel which in turn causes the
uncontrolled power tool to be forced in the direction
opposite of the wheel’s rotation at the point of the
binding.
For example, if an abrasive wheel is snagged or pinched
by the workpiece, the edge of the wheel that is entering
into the pinch point can dig into the surface of the
material causing the wheel to climb out or kick out. The
wheel may either jump toward or away from the operator,
depending on direction of the wheel’s movement at the
point of pinching. Abrasive wheels may also break under
these conditions.
Kickback is the result of power tool misuse and/or
incorrect operating procedures or conditions and can be
avoided by taking proper precautions as given below.
a) Maintain a rm grip on the power tool and
position your body and arm to allow you to resist
kickback forces. Always use auxiliary handle,
if provided, for maximum control over kickback
or torque reaction during start-up. The operator
can control torque reactions or kickback forces, if
proper precautions are taken.
b) Never place your hand near the rotating
accessory. Accessory may kickback over your hand.
c) Do not position your body in line with the rotating
wheel. Kickback will propel the tool in direction
opposite to the wheel’s movement at the point of
snagging.
d) Use special care when working corners, sharp
edges etc. Avoid bouncing and snagging the
accessory. Corners, sharp edges or bouncing have
a tendency to snag the rotating accessory and
cause loss of control or kickback.
e) Do not attach a saw chain, woodcarving blade,
segmented diamond wheel with a peripheral gap
greater than 10 mm or toothed saw blade. Such
blades create frequent kickback and loss of control.
f) Do not “jam” the wheel or apply excessive
pressure. Do not attempt to make an excessive
depth of cut. Overstressing the wheel increases the
loading and susceptibility to twisting or binding of
the wheel in the cut and the possibility of kickback
or wheel breakage.
g) When wheel is binding or when interrupting a cut
for any reason, switch off the power tool and hold
the power tool motionless until the wheel comes
to a complete stop. Never attempt to remove the
wheel from the cut while the wheel is in motion
otherwise kickback may occur. Investigate and
take corrective action to eliminate the cause of
wheel binding.
h) Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and
carefully re-enter the cut. The wheel may bind,
walk up or kickback if the power tool is restarted in
the workpiece.
i) Support panels or any oversized workpiece
to minimize the risk of wheel pinching and
kickback. Large workpieces tend to sag under their
own weight. Supports must be placed under the
workpiece near the line of cut and near the edge of
the workpiece on both sides of the wheel.
j) Use extra caution when making a “pocket cut”
into existing walls or other blind areas. The
protruding wheel may cut gas or water pipes,
electrical wiring or objects that can cause kickback.
ADDITIONAL SAFETY
RULES:
1. Always wear a dust mask.
SAFETY WARNINGS FOR
BATTERY PACK
a) Do not dismantle, open or shred cells or battery
pack.
b) Do not short-circuit a battery pack. Do not store
battery packs haphazardly in a box or drawer
where they may short-circuit each other or be
short-circuited by conductive materials.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

according to EN 62841:
Vibration emission
value:
Cutting wood:ah, = 0.469m/s2
Uncertainty K = 1.5m/s
Cutting metal: ah,M = 0.455m/s2
Uncertainty K= 1.5m/s
The declared vibration total value and the declared noise
emission value have been measured in accordance with
a standard test method and may be used for comparing
one tool with another.
The declared vibration total value and the declared
noise emission value may also be used in a preliminary
assessment of exposure.
WARNING: The vibration and noise emissions
during actual use of the power tool can differ from
the declared value depending on the ways in which the
tool is used especially what kind of workpiece is
processed dependant on the following examples and
other variations on how the tool is used:
How the tool is used and the materials being cut or
drilled.
The tool being in good condition and well maintained.
The use of the correct accessory for the tool and
ensuring it is sharp and in good condition.
The tightness of the grip on the handles and if any anti
vibration and noise accessories are used.
And the tool is being used as intended by its design and
these instructions.
This tool may cause hand-arm vibration syndrome if
its use is not adequately managed.
WARNING: To be accurate, an estimation of
exposure level in the actual conditions of use
should also take account of all parts of the operating
cycle such as the times when the tool is switched off and
when it is running idle but not actually doing the job. This
may significantly reduce the exposure level over the total
working period.
Helping to minimise your vibration and noise exposure
risk.
Always use sharp chisels, drills and blades.
Maintain this tool in accordance with these instructions
and keep well lubricated (where appropriate).
If the tool is to be used regularly then invest in anti
vibration and noise accessories.

SICHERHEITSANWEISUNGEN
FÜR ALLE SÄGEN
SÄGEVERFAHREN
a) WARNUNG: Kommen Sie mit Ihren Händen
nicht in den Sägebereich und an das
Sägeblatt. Wenn beide Hände die Kreissäge
halten, kann das Sägeblatt diese nicht verletzen.
b) Greifen Sie nicht unter das Werkstück. Die
Schutzhaube kann Sie unter dem Werkstück
nicht vor dem Sägeblatt schützen.
c) Passen Sie die Schnittiefe an die Dicke des
Werkstückes an. Es sollte weniger als eine volle
Zahnhöhe unter dem Werkstück sichtbar sein.
d) Halten Sie das zu sägende Werkstück niemals
mit der Hand oder über dem Bein fest. Sichern
Sie das Werkstück an einer stabilen Unterlage.
Es ist wichtig, das Werkstück gut zu befestigen,
um die Gefahr von Körperkontakt, Klemmen
des Sägeblattes oder Verlust der Kontrolle zu
minimieren.
e) Halten Sie das Gerät nur an den isolierten
Grifächen, wenn Sie Arbeiten ausführen,
bei denen das Einsatzwerkzeug verborgene
Stromleitungen. Der Kontakt mit einer
spannungsführenden Leitung kann auch
metallene Geräteteile unter Spannung setzen
und zu einem elektrischen Schlag führen.
f) Verwenden Sie beim Längsschneiden immer
einen Anschlag oder eine gerade Kantenführung.
Dies verbessert die Schnittgenauigkeit und
verringert die Möglichkeit, dass das Sägeblatt
klemmt.
g) Verwenden Sie immer Sägeblätter in der richtigen
Grösse und mit passender Aufnahmebohrung
(z.B. sternförmig oder rund). Sägeblätter, die
nicht zu den Montageteilen der Säge passen,
laufen unrund und führen zum Verlust der
Kontrolle.
h) Verwenden Sie niemals beschädigte oder falsche
Sägeblatt-Unterlegscheiben (Flansche) oder
–schrauben. Die Sägeblatt-Unterlegscheiben
und –schrauben wurden speziell für Ihre
Säge konstruiert, für optimale Leistung und
Betriebssicherheit.
URSACHEN UND
VERMEIDUNG EINES
RÜCKSCHLAGES
Ursachen eines Rückschlags und diesbezügliche
Warnhinweise
— Ein Rückschlag ist die plötzliche Reaktion infolge eines
hakenden, klemmenden oder falsch ausgerichteten
Sägeblattes, die dazu führt, daß eine unkontrollierte Säge
abhebt und sich aus dem Werkstück heraus in Richtung
der Bedienperson bewegt;
— Wenn sich das Sägeblatt in dem sich schließenden
Sägespalt verhakt oder verklemmt, blockiert es, und die
Motorkraft schlägt das Gerät in Richtung der Bedienperson
zurück;
— Wird das Sägeblatt im Sägeschnitt verdreht oder
falsch ausgerichtet, können sich die Zähne der hinteren
Sägeblattkante in der Oberfläche des Werkstücks
verhaken, wodurch sich das Sägeblatt aus dem Sägespalt
herausbewegt und die Säge in Richtung der Bedienperson
zurückspringt.
Ein Rückschlag ist die Folge eines falschen oder
fehlerhaften Gebrauchs der Säge. Er kann durch geeignete
Vorsichtsmaßnahmen, wie nachfolgend beschrieben,
verhindert werden.
a) Halten Sie die Säge und bringen Sie Ihre Arme in
eine Stellung, in der Sie den Rückschlagkräften
standhalten können. Halten Sie sich immer
seitlich des Sägeblattes, nie das Sägeblatt in
eine Linie mit Ihrem Körper bringen. Bei einem
Rückschlag kann die Kreissäge rückwärts
springen, jedoch kann die Bedienperson die
Rückschlagkräfte beherrschen, wenn geeignete
