For your safety.
Read all safety warnings and
all instructions. Failure to fol-
low the warnings and instructions may result
in electric shock, fire and/or serious injury.
Save all warnings and instructions for future-
reference.
Do not use this power tool before you
have thoroughly read and completely
understood this Instruction Manual, including
the figures, specifications, safety regulations
and the signs indicating DANGER, WARNING
and CAUTION.
Only carry out such operations with this
power tool as intended for by GRIT. Only use
application tools and accessories that have
been released by GRIT.
Please also observe the relevant national
industrial safety regulations.
Non-observance of the safety instructions in
the said documentation can lead to an electric
shock, burns and/or severe injuries.
This Instruction Manual should be kept for
later use and enclosed with the power tool,
should it be passed on or sold.
SAVE THESE INSTRUCTIONS.
The term “power tool” in the warnings refers
to your mains-operated (corded) power tool
or battery operated (cordless) power tool.
General safety rules.
1) Work area safety
a)Keep work area clean and well lit. Clut-
tered or dark areas invite accidents.
b)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.
c) Keep children and bystanders away
while operating a power tool. Distrac-
tion 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, radia-
tors, 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 out-
door use. Use of a cord suitable for out-
door use reduces the risk of electric
shock.
f) If operating a power tool in a damp loca-
tion is unavoidable, use a ground fault
circuit interrupter (GFCI) protected sup-
ply. Use of an GFCI 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 influ-
ence of drugs, alcohol or medication. A
moment of inattention while operating
power tools may result in serious per-
sonal injury.
b)Use personal protective equipment.
Always wear eye protection. Protective
equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing pro-
tection used for appropriate conditions
will reduce personal injuries.
WARNING

4en
c) Prevent unintentional starting. Ensure
the switch is in the off-position before
connecting to power source and/or bat-
tery 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 rotat-
ing 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 cloth-
ing or jewelery. Keep your hair, clothing
and gloves away from moving parts.
Loose clothes, jewelry or long hair can
be caught in moving parts.
g)If devices are provided for the connec-
tion of dust extraction and collection
facilities, ensure these are connected
and properly used. Use of dust collec-
tion can reduce dust-related hazards.
4) Power tool use and care
a)Do not force the power tool. Use the cor-
rect power tool for your application. The
correct power tool will do the job bet-
ter 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 the battery pack from the
power tool before making any adjust-
ments, 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 unfa-
miliar 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. Check for mis-
alignment or binding of moving parts,
breakage of parts and any other condi-
tion 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 hazardous sit-
uation.
5) Service
a)Have your power tool serviced by a qual-
ified repair person using only identical
replacement parts. This will ensure that
the safety of the power tool is main-
tained.
Special safety instructions.
Hold power tool by insulated gripping sur-
faces, because the belt may contact its own
cord. Cutting a “live” wire may make exposed
metal parts of the power tool “live” and could
give the operator an electric shock.
Wear personal protective equipment. Depend-
ing on application, use face shield, safety
goggles or safety glasses. Where appropriate,
wear dust mask, hearing protectors, gloves
and workshop apron capable of stopping
small abrasive or workpiece fragments. The
safety glasses must be capable of protecting
against flying particles generated by the vari-
ous operations. Prolonged exposure to high
intensity noise may cause loss of hearing.
While working, do not wear loose clothing,
jewellery or open, long hair. Despite protec-
tive devices, loose objects can be snagged or
caught by moving parts and lead to injury.

Do not use worn, torn or heavily clogged
grinding belts. Handle grinding belts carefully
and store them according to the manufac-
turer’s instructions. Do not bend or fold grind-
ing belts! Damaged grinding belts can tear, be
flung away and injure someone.
Never touch the running grinding belt and do
not reach under the protective guard. Danger
of injury.
Always use the protective devices attached on
the machine. The protective devices must be
securely mounted to the machine in order to
achieve maximum safety. The protective
devices are supposed to protect the user from
grinding particles thrown from the machine
and from accidental contact with the grinding
belt.
Warning! Danger of fire and explosion! When
grinding metals (e.g., aluminium or magne-
sium), dust develops that may be combustible
or explosive. Do not operate the machine near
flammable materials. Sparks could cause
these materials to ignite.
Pay attention that other persons are not put at
risk from sparking. Remove flammable mate-
rials in close vicinity. Sparking occurs when
grinding metal.
Secure the work piece firmly. A work piece
that is gripped tightly in a clamping device or
vice, is more secure than if held by hand.
Hold the power tool firmly. High reaction
torque can briefly occur.
Never touch the running grinding belt. Danger
of injury.
Do not rivet or screw any name-plates or
signs onto the power tool. If the insulation is
damaged, protection against an electric shock
will be ineffective. Adhesive labels are recom-
mended.
Do not use accessories which are not specifi-
cally designed and recommended by the
power tool manufacturer. Safe operation is
not ensured merely because an accessory fits
your power tool.
Clean the ventilation openings on the power
tool at regular intervals using non-metal
tools. The blower of the motor draws dust
into the housing. An excessive accumulation
of metallic dust can cause an electrical hazard.
Before putting into operation, check the
power connection and the power plug for
damage.
Recommendation: The tool should always be
supplied with power via a ground fault circuit
interrupter (GFCI) with a rated current of
30 mA or less.
Handling hazardous dusts.
When working with power
tools, such as when grinding,
sanding, polishing, sawing or for other work
procedures where material is removed, dusts
develop that are both hazardous to one’s
health and can spontaneously combust or be
explosive.
Contact with or inhaling some dust types can
trigger allergic reactions to the operator or
bystanders and/or lead to respiratory infec-
tions, cancer, birth defects or other reproduc-
tive harm.
Examples of such materials which contain
chemicals that can produce hazardous dusts,
are:
–Asbestos and materials containing asbes-
tos;
–Lead-containing coatings, some wood
types such as beech and oak;
–Minerals and metal;
–Silicate particles from bricks, concrete and
other materials containing stone;
–Solvent from solvent-containing paint/
varnish;
–Arsenic, chromium and other wood pre-
servatives;
–Materials for pesticide treatment on boat
and ship hulls;
–Stainless steel dust, metal dust and non-
ferrous metal dust;
WARNING

6en
To minimize the unwanted intake of these
materials:
–Use dust extraction matched appropriately
for the developing dust.
–Use personal protective equipment, such
as a P2 filter-class dust protection mask.
–Provide for good ventilation of the work-
place.
The risk from inhaling dusts depends on how
often these materials are worked. Materials
containing asbestos may only be worked on
by specialists.
Wood and light-metal dust can
cause spontaneous combus-
tion or explosions.
Hot mixtures of sanding dust and paint/var-
nish remainders or other chemical materials
in the filter bag or the vac filter can self-ignite
under unfavorable conditions, such as spark-
ing from sanding metal, continuous sunlight
or high ambient temperatures. To prevent
this:
–Avoid overheating the material being
sanded and the power tool.
–Empty the dust collector/container in time.
–Observe the material manufacturer’s
working instructions.
–Observe the relevant regulations in your
country for the materials being worked.
Hand/arm vibrations.
While working with this power
tool, hand/arm vibrations
occur. These can lead to health impairments.
The vibration emission value
during actual use of the power
tool can differ from the declared value
depending on the ways in which the tool is
used.
It is necessary to identify safety
measures to protect the oper-
ator that are based on an estimation of expo-
sure in the actual conditions of use.
The vibration emission level given in this
information sheet has been measured in
accordance with a standardised test given in
EN 60745 and may be used to compare one
tool with another. It may be used for a pre-
liminary assessment of exposure.
The declared vibration emission level repre-
sents the main applications of the tool. How-
ever if the tool is used for different
applications, with different accessories or
poorly maintained, the vibration emission
may differ. This may significantly increase the
exposure level over the total working period.
An estimation of the level of exposure to
vibration should also take into account the
times when the tool is switched off or when
it is running but not actually doing the job.
This may significantly reduce the exposure
level over the total working period.
Identify additional safety measures to protect
the operator from the effects of vibration
such as: maintain the tool and the accessories,
keep the hands warm, organisation of work
patterns.

don d’alimentation) ou votre outil fonction-
nant sur batterie (sans cordon
d’alimentation).
Instructions générales de
sécurité.
1) Portée
a)Conserver la zone de travail propre et
bien éclairée. Les zones en désordre ou
sombres sont propices aux accidents.
b)Ne pas faire fonctionner les outils élec-
trique en atmosphère explosive, par
exemple en présence de liquides inflam-
mables, de gaz ou de poussières. Les
outils électroportatifs produisent des
étincelles qui peuvent enflammer les
poussières ou les fumées.
c) Maintenir les enfants et les personnes
présentes à l’écart pendant l’utilisation
de l’outil. Les distractions peuvent vous
faire perdre le contrôle de l’outil.
2) Sécurité électrique
a)Il faut que les fiches de l’outil électrique
soient adaptées au socle. Ne jamais
modifier la fiche de quelque façon que
ce soit. Ne pas utiliser d’adaptateurs
avec des outils à branchement de terre.
Des fiches non modifiées et des socles
adaptés réduiront le risque de choc
électrique.
b)Éviter tout contact du corps avec des
surfaces reliées à la terre telles que les
tuyaux, les radiateurs, les cuisinières et
les réfrigérateurs. Il existe un risque
accru de choc électrique si votre corps
est relié à la terre.
c) Ne pas exposer les outils à la pluie ou à
des conditions humides. La pénétration
d’eau à l’intérieur d’un outil augmentera
le risque de choc électrique.
d)Veiller à ne pas endommager le cordon.
Ne jamais utiliser le cordon pour porter,
tirer ou débrancher l’outil. Maintenir le
cordon à l’écart de la chaleur, du lubri-
fiant, des arêtes ou des parties en mou-
vement. Des cordons endommagés ou
emmêlés augmentent le risque de choc
électrique.
e) Lorsqu’on utilise un outil à l’extérieur,
utiliser un prolongateur adapté à l’utili-
sation extérieure. L’utilisation d’un cor-
don adapté à l’utilisation à l’extérieur
réduit le risque d’électrocution.
f) Si l’usage d’un outil dans un emplace-
ment humide est inévitable, utilisez une
alimentation protégée par un dispositif
à courant différentiel résiduel (RCD).
L’usage d’un RCD réduit le risque de
choc électrique.
