Cordless grinder safety warnings
Safety Warnings Common for Grinding, Wire
Brushing, or Abrasive Cutting-O Operations:
1. This power tool is intended to function as a
grinder, wire brush or cut-o tool. Read all
safety warnings, instructions, illustrations and
specications 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 sanding or polishing are
not recommended 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
manufacturer. 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 acces-
sories 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.

9ENGLISH
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 caus-
ing 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.
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 Specic for Grinding and Abrasive
Cutting-O Operations:
1. Use only wheel types that are recommended
for your power tool and the specic 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 dierent 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 Specic 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
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.
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 Specic 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.

10 ENGLISH
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 X-LOCK holder.
Damage to the 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 specied surface of the wheel to per-
form the grinding.
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. Do not touch accessories immediately after
operation; it may be extremely hot and could
burn your skin.
10. Observe the instructions of the manufacturer
for correct mounting and use of wheels.
Handle and store wheels with care.
11. Do not use separate reducing bushings or
adaptors to adapt large hole abrasive wheels.
12. Check that the workpiece is properly
supported.
13. Pay attention that the wheel continues to
rotate after the tool is switched o.
14. If working place is extremely hot and humid,
or badly polluted by conductive dust, use a
short-circuit breaker (30 mA) to assure opera-
tor safety.
15. Do not use the tool on any materials contain-
ing asbestos.
16. When use cut-o wheel, always work with
the dust collecting wheel guard required by
domestic regulation.
17. Cutting discs must not be subjected to any
lateral pressure.
18. Do not use cloth work gloves during operation.
Fibers from cloth gloves may enter the tool, which
causes tool breakage.
19. Before operation, make sure that there is no
buried object such as electric pipe, water pipe
or gas pipe in the workpiece. Otherwise, it may
cause an electric shock, electrical leakage or gas
leak.

quate pressure. Forcing and excessive pressure
could cause dangerous wheel breakage.
WARNING: ALWAYS replace wheel if tool is
dropped while grinding.
WARNING: NEVER hit the workpiece with the
wheel.
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.
WARNING: Never actuate the release lever of
the X-LOCK holder during operation. The X-LOCK
wheel comes o from the tool and may cause serious
injury.
WARNING: Make sure that the X-LOCK wheel

Grinding operation
► Fig.19
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.
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.

SÄKERHETSVARNINGAR
Allmänna säkerhetsvarningar för
maskiner
VARNING: Läs alla säkerhetsvarningar, anvis-
ningar, illustrationer och specikationer som
medföljer det här maskinen. Underlåtenhet att följa
instruktionerna kan leda till elstötar, brand och/eller
allvarliga personskador.
Spara alla varningar och instruk-
tioner för framtida referens.
Termen ”maskin” som anges i varningarna hänvisar till
din eldrivna maskin (sladdansluten) eller batteridrivna
maskin (sladdlös).
Säkerhetsvarningar för batteridriven
slipmaskin
Gemensamma säkerhetsvarningar för slipning,
stålborstning eller abrasiv skärning:
1. Den här maskinen är utformad för att använ-
das för slipning, stålborstning eller som skär-
verktyg. Läs igenom alla säkerhetsvarningar,
anvisningar, illustrationer och specikationer
som medföljer detta verktyg. Underlåtenhet att
följa instruktionerna kan leda till elstötar, brand
och/eller allvarliga personskador.
2. Den här maskinen rekommenderas inte
för sandpapprings- eller poleringsarbeten.
Om verktyget används till andra arbeten än
de avsedda kan det orsaka fara och leda till
personskada.
3. Använd inte tillbehör som inte är särskilt till-
verkade och rekommenderade av maskinens
tillverkare. Även om ett tillbehör kan fästas på
maskinen garanterar detta inte säker funktion.
4. Tillbehörets nominella varvtal måste vara
minst lika med det maximala varvtalet som
anges på verktyget. Tillbehör som används över
det nominella varvtalet kan gå sönder och orsaka
skador.
5. Tillbehörets ytterdiameter och tjocklek måste
vara anpassad till elverktygets kapacitets-
klassning. Tillbehör i olämplig storlek kan inte
skyddas eller styras tillräckligt väl.
6. Gängorna på tillbehör som monteras måste
stämma överens med spindelgängorna på
slipmaskinen. För tillbehör som monteras med
änsar måste tillbehörets centrumhål passa i
änsens lokaliseringsdiameter. Tillbehör som
inte passar exakt på maskinens monteringsbeslag
roterar ojämnt, vibrerar kraftigt och kan leda till att
du förlorar kontrollen.
7. Använd inte ett skadat tillbehör. Kontrollera
tillbehör som sliprondeller efter hack och
sprickor, underlagsplattor efter sprickor,
slitage och stålborstar efter lösa eller brutna
trådar. Om du tappar maskinen eller ett tillbe-
hör ska du kontrollera att det inte har uppstått
några skador, eller så ska tillbehöret bytas ut
mot ett oskadat. Efter kontroll och montering
av tillbehöret ska du och åskådare hålla er
borta från det roterande tillbehöret samtidigt
som du kör maskinen på full fart utan last i
en minut. Skadade tillbehör går normalt sönder
under den här testtiden.
8. Använd personlig skyddsutrustning. Använd
visir, korgglasögon eller skyddsglasögon
beroende på arbetsuppgift. Använd vid
behov dammskydd, hörselskydd, handskar
och skyddsförkläde som stoppar små bitar
slipmaterial eller fragment från arbetss-
tycket. Ögonskyddet måste kunna stoppa y-
gande fragment som uppstår vid olika arbeten.
Dammskyddet eller andningsskyddet måste kunna
ltrera partiklar som uppstår vid olika arbeten.
Lång tid i kraftigt buller kan orsaka hörselskador.

19 SVENSKA
9. Håll personer i omgivningen på säkert avstånd
från arbetsområdet. Alla som benner sig
i arbetsområdet måste använda skyddsut-
rustning. Delar av arbetsstycket eller defekta
tillbehör kan yga iväg och orsaka skador utanför
arbetsområdet.
10. Håll maskinen endast i de isolerade handtagen
om det nns risk för att skärverktyget kan
komma i kontakt med en dold elkabel. Om skär-
verktyget kommer i kontakt med en strömförande
ledning blir maskinens metalldelar strömförande
och kan ge användaren en elektrisk stöt.
11.
Lägg aldrig elverktyget åt sidan förrän det har
stannat helt. Det roterande tillbehöret kan gripa tag i
underlaget och du kan förlora kontrollen över maskinen.
12. Kör inte verktyget samtidigt som du bär det.
Oavsiktlig kontakt med det roterande tillbehöret
kan leda till att det fastnar i dina kläder och dras in
mot kroppen.
13. Rengör regelbundet verktygets ventilations-
öppningar. Motorns äkt suger in damm i höljet
och överdriven ansamling av pulveriserad metall
kan orsaka elektrisk fara.
14. Använd inte verktyget i närheten av lättan-
tändliga material. Gnistor kan antända dessa
material.
15.
Använd inte tillbehör som kräver ytande kyl-
vätskor. Att använda vatten eller andra ytande
kylvätskor kan orsaka dödsfall eller elektriska stötar.
Bakåtkast och relaterade varningar
Bakåtkast är en plötslig reaktion på fastnypt roterande
hjul, underlagsplatta, borste eller annat tillbehör. Nyp
och kärvning orsakar stegring av det roterande tillbehö-
ret, och orsakar i sin tur att den okontrollerade maski-
nen tvingas i motsatt riktning vid kärvningspunkten.
Om till exempel en slipskiva fastnar i eller kläms fast av
arbetsstycket kan skivans kapande kant gräva sig in i
materialytan vid klämpunkten, vilket leder till att skivan
klättrar eller kastas tillbaka. Skivan kan antingen hoppa
mot eller från användaren, beroende på skivans rörel-
seriktning vid klämpunkten. Slipskivorna kan även gå
sönder under dessa omständigheter.
Bakåtkast beror på ovarsamhet och/eller felaktiga
arbetsrutiner, och kan undvikas genom att vidta nedan-
stående förebyggande åtgärder.
1. Se till att hålla verktyget i ett fast grepp och
placera kroppen och din arm på ett sätt som
gör att du kan stå emot kraften från bakåtkast.
Använd alltid ett extrahandtag, om sådant
nns, för maximal kontroll vid bakåtkast eller
vridrörelsen vid start. Användaren kan kontroll-
era vridrörelsen eller krafterna vid bakåtkast om
rätt försiktighetsåtgärder vidtas.
2. Placera aldrig din hand nära det roterande
tillbehöret. Tillbehöret kan kastas bakåt över din
hand.
3. Ställ dig inte där maskinen kommer att förytta
sig i händelse av bakåtkast. Bakåtkast driver
verktyget i motsatt riktning till kapskivans rörelse
vid kärvningspunkten.
4. Var extra försiktig när du bearbetar hörn,
vassa kanter osv. Undvik att studsa och stöta
tillbehöret. Hörn, skarpa kanter eller studsning
har en tendens att klämma det roterande tillbehö-
ret och orsaka förlorad kontroll eller bakåtkast.
5. Montera inte en sågkedja, snidarblad eller ett
tandat sågblad. Sådana blad orsakar ofta bakåt-
kast och förlorad kontroll.
Säkerhetsvarningar för slipning och abrasiv
skärning:
1. Använd endast de skivor som rekommenderas
för din maskin och det särskilda sprängskyd-
det för skivan. Skivor som inte tillverkats för
maskinen kan inte skyddas tillräckligt och är inte
tillförlitliga.
2. Slipytan på nedsänkta skivor måste monte-
ras under planet från sprängskyddets kant.
En felaktigt monterad skiva som sticker utanför
planet från sprängskyddets kant är inte tillräckligt
skyddad.
3. Sprängskyddet måste vara ordentligt fäst vid
maskinen och placerat för maximal säkerhet,
så att minsta möjliga yta av skivan är öppen
mot användare. Sprängskyddet skyddar använ-
daren mot trasiga skivdelar, oavsiktlig kontakt med
skivan och gnistor som kan antända kläder.
4. Kapskivorna får endast användas till rekom-
menderade arbetsuppgifter. Till exempel: Slipa
inte med en kapskivas utsida. Slipande kapski-
vor är avsedda för periferislipning. Sidokrafter kan
spränga sådana skivor.
5. Använd alltid oskadade skivänsar i rätt stor-
lek och form till din skiva. Rätt skivänsar stöder
kapskivan och minskar därigenom risken för att
skivan går sönder. Flänsar till kapskivor kan skilja
sig från änsar till slipskivor.
6. Använd inte nedslitna skivor för större maski-
ner. Skivor avsedda för större maskiner är inte
lämpliga för mindre maskiners högre varvtal och
kan spricka.
Ytterligare särskilda säkerhetsvarningar för abrasiv
skärning:
1.
”Pressa” inte skivan eller utsätt den för överdrivet
tryck. Försök inte att göra ett alltför stort kapdjup.
Om kapskivan överbelastas ökar belastningen och
risken för att skivan vrids eller fastnar i kapet samt
risken för bakåtkast eller att skivan går sönder.
2. Placera inte din kropp längs med eller bakom
den roterande skivan. När skivan rör sig ifrån
dig, kan ett bakåtkast skicka den roterande skivan
och maskinen mot dig.
3. Om kapskivan kärvar eller om ett kap avbryts
stänger du av elverktyget och håller det stilla
tills skivan har stannat helt. Försök aldrig att ta
ut kapskivan ur skäret när skivan är i rörelse,
för att undvika bakåtkast. Undersök och vidta
korrigeringsåtgärder för att eliminera orsaken till
att kapskivan fastnar.
4. Starta inte om kapningen med verktyget kvar i
arbetsstycket. Låt maskinen nå full hastighet
och gå tillbaka i skäret. Kapskivan kan fastna,
vandra uppåt eller kastas bakåt om elverktyget
startas om i arbetsstycket.
5. Stötta långa eller stora arbetsstycken för att
minimera risken för att kapskivan fastnar
och kastas bakåt. Stora arbetsstycken tenderar
att svikta på grund av sin egen vikt. Stöd måste
placeras under arbetsstycket nära såglinjen och
nära arbetsstyckets kanter på båda sidorna om
kapskivan.

20 SVENSKA
6. Var extra försiktig vid genomstickssågning i
en bentlig vägg eller andra dolda utrymmen.
Den utskjutande kapskivan kan kapa gas- eller
vattenledningar, elledningar eller föremål som kan
orsaka bakåtkast.
Säkerhetsvarningar särskilt vid stålborstning:
1. Var uppmärksam på att trådbitar kastas ut
från borsten även vid normal användning.
Överbelasta inte trådarna genom att anlägga
onödigt stor kraft mot borsten. Trådarna kan
enkelt gå igenom tunnare klädsel och/eller huden.
2. Om användning av skydd rekommenderas
vid stålborstningfår inte borstskivan eller
borsten gå emot skyddet. Borstens diameter
kan expandera på grund av belastningen eller
centrifugalkraften.
Ytterligare säkerhetsvarningar:
1. Vid användning av nedsänkta center-rondel-
ler ska endast glasberförstärkta rondeller
användas.
2. ANVÄND ALDRIG sten-skålskivor med denna
slipmaskin. Denna slipmaskin är inte konstrue-
rad för denna typ av skivor och användningen av
dessa kan resultera i allvarlig personskada.
3. Var noga med att inte skada X-LOCK-hållaren.
Skador på delarna kan medföra att rondellen
förstörs.
4. Se till att rondellen inte är i kontakt med
arbetsstycket när du trycker på avtryckaren.
5. Låt verktyget vara igång en stund innan det
används på arbetsstycket. Kontrollera att ski-
van inte vibrerar eller skakar, vilket kan inne-
bära att den är felaktigt monterad eller dåligt
balanserad.
6. Slipa endast med den del av rondellen som är
avsedd för slipning.
7. Lämna inte maskinen igång. Använd endast
maskinen när du håller den i händerna.
8. Rör inte vid arbetsstycket omedelbart efter
arbetet. Det kan vara extremt varmt och orsaka
brännskador.
9. Rör inte vid tillbehör omedelbart efter arbe-
tet. Det kan vara extremt varmt och orsaka
brännskador.
10. Följ tillverkarens anvisningar för korrekt mon-
tering och användning av rondeller. Hantera
rondellerna varsamt och förvara dem på en
säker plats.
11. Använd inte separata reducerhylsor eller adap-
trar för att kunna använda sliprondeller med
större hål.
12. Kontrollera att arbetsstycket är ordentligt
fastsatt.
13. Tänk på att rondellen fortsätter att rotera efter
att maskinen stängts av.
14. Om arbetsplatsen är extremt varm och fuk-
tig, eller har hög koncentration av elektriskt
ledande damm, ska jordfelsbrytare (30 mA)
användas för användarens säkerhet.
15. Använd inte maskinen för material som
innehåller asbest.
16. Använd alltid föreskrivet dammuppsamlande
sprängskydd när du arbetar med kapskiva.
17. Kapskivor får inte utsättas för sidokrafter.
18. Använd inte arbetshandskar i tyg när du arbe-
tar med maskinen. Fibrer från tyghandskar kan
komma in i maskinen och orsaka fel.
19. Innan användning måste du se till att det inte
nns några begravda föremål som elrör, vat-
tenrör eller gasrör i arbetsstycket. Annars kan
det orsaka elstöt, elektriskt läckage eller gasläcka.
SPARA DESSA ANVISNINGAR.
VARNING: GLÖM INTE att också fortsätt-
ningsvis strikt följa säkerhetsanvisningarna för
maskinen även efter att du blivit van att använda
den. Vid FELAKTIG HANTERING av maskinen
eller om inte säkerhetsanvisningarna i denna
bruksanvisning följs kan följden bli allvarliga
personskador.
