4. Special Safety Instructions
4.1 Cut-omachinesafetywarnings
a) Position yourself and bystanders away from the
plane of the rotating wheel. The guard helps to
protect the operator from broken wheel fragments
and accidental contact with wheel.
b) Use only bonded reinforced cut-o wheels for
your power tool. Just because an accessory can
ENGLISHen
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 y apart.
d) Wheels must be used only for recommended
applications. For example: do not grind with the side
of a cut-o wheel. Abrasive cut-o 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 anges support the wheel thus reducing the
possibility of wheel breakage.
f) 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.
g) The arbour size of wheels and anges must
properly t the spindle of the power tool. Wheels
and anges 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.
h) Do not use damaged wheels. Before each use,
inspect the wheels for chips and cracks. If the
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.
i) 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
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.
j) 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 y away and
cause injury beyond immediate area of operation.
k) Position the cord clear of the spinning
accessory. If you lose control, the cord may be cut
or snagged and your hand or arm may be pulled
into the spinning wheel.
l) Regularly clean the power tool’s air vents. The
motor’s fan can draw the dust inside the housing
and excessive accumulation of powdered metal
may cause electrical hazards.
m) Do not operate the power tool near ammable
materials. Do not operate the power tool while
5
Page 6
en ENGLISH
placed on a combustible surface such as wood.
Sparks could ignite these materials.
n) Do not use accessories that require liquid
coolants. Using water or other liquid coolants may
result in electrocution or shock.
4.2 Kickbackandrelatedwarnings
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 cutting unit to be forced
upwards toward the operator.
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. 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. The operator can control upward kickback
forces, if proper precautions are taken.
b) Do not position your body in line with the rotating
wheel. If kickback occurs, it will propel the cutting unit
upwards toward the operator.
c) 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.
d) 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.
e) When the wheel is binding or when interrupting a
cut for any reason, switch o the power tool and hold
the cutting unit 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.
f) 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.
g) Support 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.
4.3 AdditionalSafetyInstructions
Always wear eye protection and hearing
protection. Put on other protective gear if
necessary, such as dust masks, gloves,
6
helmet and apron. When judging if face or dust
masks are necessary, take into consideration
whether the workpiece to be machined or its coating
are potentially harmful to health. Put on protective
clothing in case of doubt.
Wear ear protectors when working for long periods of
time. High noise levels over a prolonged period of
time may aect your hearing.
Do not work with magnesium.
Do not use power tools in a damp or wet
environment.
Do not use the machine in environments where there
is the risk of explosion, in which sparks can cause
re, explosions or the like.

discs for dry cuts, the strength may be reduced by
moisture or water.
Handle the cutting disc with caution. Protect the
cutting disc from jolts or impacts.
Always use equipment that fulls the following
minimum requirements:
Only cutting discs with resinoid bonding and bre
reinforcement can be used. The maximum rotations
per minute (rpm) of the cutting disc must not be lower
than the machine idling speed.
Adhere to the maximum cutting disc diameter (see
technical data).
Use no cutting discs that are thicker than 3 mm (3/
32").
The bore of the cutting disc must t the toolholder
without any clearance. Do not use adapters or
reducers.
Observe the specications of the tool or accessory
manufacturer!
Adhere to the cutting disc instruction manual.
Use elastic cushioning layers if they have been
supplied with the sanding media and if required.
Be particularly cautious with the parts that are
connected to the cutting disc. Take care not to
damage the spindle, ange or screw. Damage to
these parts can cause the cutting disc to break.
It must be ensured that mounted cutting discs are
installed in accordance with the manufacturer
specications.
Before use, make sure the cutting discs are correctly
xed and fastened, and operate the machine in idling
mode for 30 s. Immediately switch o the machine if
strong vibrations or other malfunctions occur. Should
they occur, inspect the machine to nd the cause.
When the cutting disc is used up to the wear limit (1/
3 of the outer diameter), replace the cutting disc.
Pull the plug out of the plug socket before any
adjustments or servicing are performed.
The cutting disc continues to rotate after the machine
has been switched o.
ENGLISHen

motor is inoperative.
Do not touch the rotating cutting disc.
Danger of injury!
When the cutting disc vibrates too strongly in idling
mode, it can lead to breakage. In case of irregularities
during use, immediately switch o the machine and
have it repaired.
Secure the workpiece. Use the vice to secure the
workpiece.
Do not try to saw extremely small workpieces.
During machining, the workpiece must be rmly
supported and secured against moving.
Long workpieces must be suciently supported.
Begin cutting only after having reached the max.
rpm.
Use only the cutting edge of the cutting disc to cut.
Do not use the lateral surface of the cutting disc for
grinding jobs.
When working on workpieces with curves or inclined
surfaces, make sure that no lateral pressure is
applied to the cutting disc.
Ensure that sparks produced during work do not
constitute a risk to the user or other personnel and
are not able to ignite inammable substances.
Endangered areas must be protected with
ameresistant covers.
Make sure that re-risk areas are always provided
with suitable re extinguishers.
The workpiece can be very hot after having been
machined. Caution, risk of burning!
Reducingdustexposure:
WARNING - Some dust created by power
sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known to
cause cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
- Lead from lead-based paints,
- Crystalline silica from bricks and cement and other
masonry products, and
- Arsenic and chromium from chemically treated
lumber.
Your risk from these exposures varies, depending on
how often you do this type of work. To reduce your
exposure to these chemicals: work in a well ventilated
area, and work with approved safety equipment, such
as those dust masks that are specially designed to
lter out microscopic particles.
This also applies to dust from other materials such as
some timber types (like oak or beech dust), metals,
asbestos. Other known diseases are e.g. allergic
reactions, respiratory diseases. Do not let dust enter
the body.
Observe the relevant guidelines and national
regulations for your material, sta, application and
place of application (e.g. occupational health and
safety regulations, disposal).
