(cordless) power tool.
Cordless grinder safety warnings
Safety Warnings Common for Grinding, Sanding,
Wire Brushing, or Abrasive Cutting-O󰀨 Operations:
1.
This power tool is intended to function as a
grinder, sander, wire brush or cut-o󰀨 tool. 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, re and/or serious injury.
2. Operations such as polishing are not recom-
mended to be performed with this power tool.
Operations for which the power tool was not designed
may create a hazard and cause personal injury.
3. Do not use accessories which are not specically
designed and recommended by the tool manufac-
turer. Just because the accessory can be attached to
your power tool, it does not assure safe operation.
4. 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 y apart.
5. 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.
6.
Threaded mounting of accessories must match
the grinder spindle thread. For accessories
mounted by anges, the arbour hole of the
accessory must t the locating diameter of the
ange. Accessories that do not match the mounting
hardware of the power tool will run out of balance,
vibrate excessively and may cause loss of control.
7. Do not use a damaged accessory. Before each
use inspect the accessory such as abrasive
wheels for chips and cracks, backing pad for
cracks, tear or excess wear, wire brush for
loose or cracked wires. If power tool or acces-
sory is dropped, inspect for damage or install
an undamaged accessory. After inspecting and
installing an accessory, position yourself and
bystanders away from the plane of the rotating
accessory and run the power tool at maximum
no-load speed for one minute. Damaged acces-
sories will normally break apart during this test
time.
8. Wear personal protective equipment.
Depending on application, use face shield,
safety goggles or safety glasses. As appro-
priate, wear dust mask, hearing protectors,
gloves and workshop apron capable of stop-
ping small abrasive or workpiece fragments.
The eye protection must be capable of stopping
ying debris generated by various operations.
The dust mask or respirator must be capable of
ltrating particles generated by your operation.
Prolonged exposure to high intensity noise may
cause hearing loss.
9. 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 accessory
may y away and cause injury beyond immediate
area of operation.
10. Hold the power tool by insulated gripping
surfaces only, 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.
11. Never lay the power tool down until the acces-
sory has come to a complete stop. The spinning
accessory may grab the surface and pull the
power tool out of your control.
12. 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.
13. 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.
14. Do not operate the power tool near ammable
materials. Sparks could ignite these materials.
15. Do not use accessories that require liquid
coolants. Using water or other liquid coolants
may result in electrocution or shock.
Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or snagged
rotating wheel, backing pad, brush or any other acces-
sory. Pinching or snagging causes rapid stalling of the
rotating accessory which in turn causes the uncon-
trolled power tool to be forced in the direction opposite
of the accessory’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 move-
ment 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.

10 ENGLISH
1. 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 kick-
back forces, if proper precautions are taken.
2. Never place your hand near the rotating acces-
sory. Accessory may kickback over your hand.
3. Do not position your body in the area where
power tool will move if kickback occurs.
Kickback will propel the tool in direction opposite
to the wheel’s movement at the point of snagging.
4. 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.
5. Do not attach a saw chain woodcarving blade
or toothed saw blade. Such blades create fre-
quent kickback and loss of control.
Safety Warnings Specic for Grinding and Abrasive
Cutting-O󰀨 Operations:
1. Use only wheel types that are recommended
for your power tool and the specic guard
designed for the selected wheel. Wheels for
which the power tool was not designed cannot be
adequately guarded and are unsafe.
2. The grinding surface of centre depressed
wheels must be mounted below the plane of
the guard lip. An improperly mounted wheel that
projects through the plane of the guard lip cannot
be adequately protected.
3. The guard must be securely attached to the
power tool and positioned for maximum safety,
so the least amount of wheel is exposed
towards the operator. The guard helps to protect
the operator from broken wheel fragments, acci-
dental contact with wheel and sparks that could
ignite clothing.
4. Wheels must be used only for recommended
applications. For example: do not grind with
the side of cut-o󰀨 wheel. Abrasive cut-o󰀨 wheels
are intended for peripheral grinding, side forces
applied to these wheels may cause them to
shatter.
5. Always use undamaged wheel anges that are
of correct size and shape for your selected
wheel. Proper wheel anges support the wheel
thus reducing the possibility of wheel breakage.
Flanges for cut-o󰀨 wheels may be di󰀨erent from
grinding wheel anges.
6. Do not use worn down wheels from larger
power tools. Wheel intended for larger power tool
is not suitable for the higher speed of a smaller
tool and may burst.
Additional Safety Warnings Specic for Abrasive
Cutting-O󰀨 Operations:
1. Do not “jam“ the cut-o󰀨 wheel or apply exces-
sive 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 possibil-
ity of kickback or wheel breakage.
2. Do not position your body in line with and
behind the rotating wheel. When the wheel, at
the point of operation, is moving away from your
body, the possible kickback may propel the spin-
ning wheel and the power tool directly at you.
3. When wheel is binding or when interrupting
a cut for any reason, switch o󰀨 the power
tool and hold the power tool motionless until
the wheel comes to a complete stop. Never
attempt to remove the cut-o󰀨 wheel from the
cut while the wheel is in motion otherwise
kickback may occur. Investigate and take correc-
tive action to eliminate the cause of wheel binding.
4.
Do not restart the cutting operation in the work-
piece. 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.
5. Support panels or any oversized workpiece to
minimize the risk of wheel pinching and kick-
back. 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.
6. Use extra caution when making a “pocket cut”
into existing walls or other blind areas. The
protruding wheel may cut gas or water pipes, elec-
trical wiring or objects that can cause kickback.
Safety Warnings Specic for Sanding Operations:
1. Do not use excessively oversized sanding
disc paper. Follow manufacturers recommen-
dations, when selecting sanding paper. Larger
sanding paper extending beyond the sanding
pad presents a laceration hazard and may cause
snagging, tearing of the disc or kickback.
Safety Warnings Specic for Wire Brushing Operations:
1. Be aware that wire bristles are thrown by the
brush even during ordinary operation. Do not
overstress the wires by applying excessive
load to the brush. The wire bristles can easily
penetrate light clothing and/or skin.
2. If the use of a guard is recommended for wire
brushing, do not allow any interference of the
wire wheel or brush with the guard. Wire wheel
or brush may expand in diameter due to work load
and centrifugal forces.
Additional Safety Warnings:
1.
When using depressed centre grinding wheels,
be sure to use only berglass-reinforced wheels.
2. NEVER USE Stone Cup type wheels with this
grinder. This grinder is not designed for these
types of wheels and the use of such a product
may result in serious personal injury.
3. Be careful not to damage the spindle, the
ange (especially the installing surface) or the
lock nut. Damage to these parts could result in
wheel breakage.
4. Make sure the wheel is not contacting the
workpiece before the switch is turned on.
5. 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 wheel.
6. Use the specied surface of the wheel to per-
form the grinding.

11 ENGLISH
7. Do not leave the tool running. Operate the tool
only when hand-held.
8. Do not touch the workpiece immediately after
operation; it may be extremely hot and could
burn your skin.
9. Observe the instructions of the manufacturer
for correct mounting and use of wheels.
Handle and store wheels with care.
10. Do not use separate reducing bushings or
adaptors to adapt large hole abrasive wheels.
11. Use only anges specied for this tool.
12. For tools intended to be tted with threaded
hole wheel, ensure that the thread in the wheel
is long enough to accept the spindle length.
13.
Check that the workpiece is properly supported.
14. Pay attention that the wheel continues to
rotate after the tool is switched o󰀨.
15.
If working place is extremely hot and humid, or
badly polluted by conductive dust, use a short-cir-
cuit breaker (30 mA) to assure operator safety.
16. Do not use the tool on any materials contain-
ing asbestos.
17. When use cut-o󰀨 wheel, always work with
the dust collecting wheel guard required by
domestic regulation.
18. Cutting discs must not be subjected to any
lateral pressure.
19. Do not use cloth work gloves during operation.
Fibers from cloth gloves may enter the tool, which
causes tool breakage.
SAVE THESE INSTRUCTIONS.
WARNING: DO NOT let comfort or familiarity
with product (gained from repeated use) replace
strict adherence to safety rules for the subject
product. MISUSE or failure to follow the safety
rules stated in this instruction manual may cause
serious personal injury.

quate pressure. Forcing and excessive pressure
could cause dangerous wheel breakage.
WARNING: ALWAYS replace wheel if tool is
dropped while grinding.
WARNING: NEVER bang or hit grinding disc
or wheel onto work.
WARNING: Avoid bouncing and snagging
the wheel, especially when working corners,
sharp edges etc. This can cause loss of control and
kickback.
WARNING: NEVER use tool with wood cutting
blades and other saw blades. Such blades when
used on a grinder frequently kick and cause loss of
control leading to personal injury.
CAUTION: Never switch on the tool when it
is in contact with the workpiece, it may cause an
injury to operator.
CAUTION: Always wear safety goggles or a
face shield during operation.
CAUTION: After operation, always switch o󰀨
the tool and wait until the wheel has come to a
complete stop before putting the tool down.
CAUTION: ALWAYS hold the tool rmly with
one hand on housing and the other on the side
grip (handle).
Grinding and sanding operation
► Fig.25
Turn the tool on and then apply the wheel or disc to the
workpiece.
In general, keep the edge of the wheel or disc at an
angle of about 15° to the workpiece surface.
During the break-in period with a new wheel, do not
work the grinder in forward direction or it may cut into
the workpiece. Once the edge of the wheel has been
rounded o󰀨 by use, the wheel may be worked in both
forward and backward direction.

16 ENGLISH
Operation with abrasive cut-o󰀨 /
diamond wheel
Optional accessory
WARNING: 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, wheel breakage and overheating of the
motor may occur.
WARNING: Do not start the cutting operation
in the workpiece. Let the wheel reach full speed
and carefully enter into the cut moving the tool
forward over the workpiece surface. The wheel
may bind, walk up or kickback if the power tool is
started in the workpiece.
WARNING: During cutting operations, never
change the angle of the wheel. Placing side pres-
sure on the cut-o󰀨 wheel (as in grinding) will cause
the wheel to crack and break, causing serious per-
sonal injury.
WARNING: A diamond wheel shall be oper-
ated perpendicular to the material being cut.

Ogólne zasady bezpiecznej
eksploatacji elektronarzędzi
OSTRZEŻENIE: Należy zapoznać się z
ostrzeżeniami dotyczącymi bezpieczeństwa,
instrukcjami, ilustracjami i danymi technicz-
nymi dołączonymi do tego elektronarzędzia.
Niezastosowanie się do podanych poniżej instrukcji
może prowadzić do porażenia prądem, pożaru i/lub
poważnych obrażeń ciała.
Wszystkie ostrzeżenia i instruk-
cje należy zachować do wykorzy-
stania w przyszłości.
Pojęcie „elektronarzędzie", występujące w wymienio-
nych tu ostrzeżeniach, odnosi się do elektronarzędzia
zasilanego z sieci elektrycznej (z przewodem zasilają-
cym) lub do elektronarzędzia akumulatorowego (bez
przewodu zasilającego).
Ostrzeżenia dotyczące
bezpieczeństwa dla akumulatorowej
szlierki kątowej
Ostrzeżenia dotyczące bezpieczeństwa podczas
operacji szlifowania, czyszczenia powierzchni
szczotką drucianą lub cięcia przy użyciu ściernicy:
1. Opisywane elektronarzędzie jest przeznaczone
do szlifowania, czyszczenia powierzchni
szczotką drucianą i cięcia. Należy zapoznać się
z ostrzeżeniami dotyczącymi bezpieczeństwa,
instrukcjami, ilustracjami i danymi technicz-
nymi dołączonymi do tego elektronarzędzia.
Niezastosowanie się do podanych poniżej instruk-
cji może prowadzić do porażenia prądem elek-
trycznym, pożaru i/lub poważnych obrażeń ciała.
2. Nie zaleca się używania niniejszego elektro-
narzędzia do wykonywania takich operacji jak
polerowanie. Operacje, do których elektronarzę-
dzie nie jest przeznaczone, mogą stwarzać zagro-
żenie i spowodować obrażenia ciała.
3. Nie używać osprzętu, który nie jest przezna-
czony ani zalecany specjalnie do tego narzę-
dzia przez jego producenta. Fakt, że osprzęt
można zamocować do posiadanego elektronarzę-
dzia, wcale nie gwarantuje bezpiecznej pracy.
4. Prędkość znamionowa osprzętu powinna być
przynajmniej równa maksymalnej prędkości
podanej na elektronarzędziu. Osprzęt pracujący
przy większej prędkości niż jego prędkość zna-
mionowa może pęknąć i rozpaść się na kawałki.
5.
Zewnętrzna średnica i grubość osprzętu musi
mieścić się w zakresie dopuszczalnym dla tego
elektronarzędzia. Nie można zapewnić prawidłowej
osłony i kontroli osprzętu o niewłaściwym rozmiarze.
6. Osprzęt montowany na gwint musi pasować do
gwintu wrzeciona szlierki. W przypadku osprzętu
montowanego przy użyciu kołnierzy otwór
wewnętrzny osprzętu musi pasować do średnicy
kołnierza. Osprzęt, który nie jest dopasowany do
uchwytu mocującego w elektronarzędziu będzie
niewyważony podczas pracy, powodując nadmierne
drgania i ryzyko utraty kontroli nad narzędziem.
7. Nie używać uszkodzonego osprzętu. Przed każdo-
razowym użyciem osprzęt, np. ściernice, należy
skontrolować pod kątem ubytków lub pęknięć, tarcze
oporowe należy skontrolować pod kątem pęknięć,
uszkodzeń lub nadmiernego zużycia, a szczotki dru-
ciane pod kątem luźnych lub popękanych drutów. W
przypadku upuszczenia elektronarzędzia lub osprzętu
należy sprawdzić, czy nie doszło do uszkodzenia, lub
zamontować nieuszkodzony osprzęt. Po sprawdzeniu
bądź zamontowaniu osprzętu należy stanąć w taki
sposób i tak ustawić narzędzie, aby nikt nie znajdował
się w płaszczyźnie obrotu osprzętu, po czym na jedną
minutę uruchomić elektronarzędzie z maksymalną
prędkością bez obciążenia. Uszkodzony osprzęt zazwy-
czaj rozpadnie się podczas takiej próby.
8. Używać środków ochrony osobistej. W zależ-
ności od wykonywanej operacji należy używać
osłony twarzy, gogli lub okularów ochronnych.
W miarę potrzeb zakładać maskę przeciwpyłową,
ochronniki słuchu, rękawice i fartuch, który
zatrzyma drobiny materiału ściernego i obrabia-
nego przedmiotu. Środki ochrony oczu powinny
zatrzymywać unoszące się w powietrzu drobiny
materiału, które powstają podczas różnych operacji.
Maska przeciwpyłowa lub oddechowa powinna
ltrować cząsteczki, które powstają podczas pracy.
Przebywanie przez dłuższy czas w hałasie o dużym
natężeniu może spowodować utratę słuchu.
