Special Safety Instructions
Safety Warnings common for Grinding, Sanding
and Polishing Operations:
a] This power tool is designed to be used as a
sander (with sandpaper) and polisher. Read
all safety warnings, instructions, illustra-
tions and specifications provided with this
power tool. Failure to follow all instructions
listed below may result in electric shock, fire
and/or serious injury.
b] This power tool is not suitable for coarse
sanding, sanding with a wire brush, polishing
and abrasive cutting. Operations for which the
power tool was not designed may create a haz-
ard and cause personal injury.
c] Do not use accessories which are not specifi-
cally designed and recommended by the tool
manufacturer. Just because the accessory can
be attached to your power tool, it does not as-
sure safe operation.
d] 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.
e] The outside diameter and the thickness of
your accessory must be within the capacity
rating of your power tool. Incorrectly sized ac-
cessories cannot be adequately guarded or
controlled.
f] Threaded mounting of accessories must
match the grinder spindle thread. For acces-
sories mounted by flanges, the arbor hole of
the accessory must fit the locating diameter
of the flange. 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.
g] 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 accessories will normally break
apart during this test time.
h] Wear personal protective equipment. De-
pending on application, use face shield,
safety goggles or safety glasses. Where ap-
propriate, wear dust mask, hearing protec-
tors, gloves and workshop apron capable of
stopping small abrasive or workpiece frag-
ments. The eye protection must be capable of
stopping flying debris generated by various op-
erations. The dust mask or respirator must be
capable of filtrating particles generated by
your operation. Prolonged exposure to high in-
tensity noise may cause hearing loss.
i] 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 acces-
sory may fly away and cause injury beyond im-
mediate area of operation.
j] Hold the power tool by insulated gripping
surfaces only, when performing an operation
where the cutting accessory may contact hid-
den wiring or its own cord. Cutting accessory
contacting a “live” wire may make exposed
metal parts of the power tool “live” and could
give the operator an electric shock.
k] Position the cord clear of the spinning acces-
sory. If you lose control of the power tool, the
cord may be cut or snagged and your hand or
arm may be pulled into the spinning accessory.
l] Never lay the power tool down until the ac-
cessory has come to a complete stop. The
spinning accessory may grab the surface and
pull the power tool out of your control.
m] 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.
n] Regularly clean the power tool’s air vents.
The motor’s fan will draw the dust inside the
housing and excessive accumulation of pow-
dered metal may cause electrical hazards.
o] Do not operate the power tool near flamma-
ble materials. Sparks could ignite these mate-
rials.
p] 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 accessory. Pinching or snagging causes rapid
stalling of the rotating accessory which in turn
causes the uncontrolled 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 movement at the point of pinching.
Abrasive wheels may also break under these con-
ditions.
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 firm grip on the power tool and po-
sition your body and arm to allow you to re-
sist 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 ac-
cessory. Accessory may kickback over your
hand.
.c] Do not position your body in the area where
power tool will move if kickback occurs. Kick-
back 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
or toothed saw blade. Such blades create fre-
quent kickback and loss of control over the
power tool.
Additional safety instructions
Never immerse the machine in water or spray it
with water for cleaning, not even the tool holder!
Keep liquids away from the power tool and persons
in the work area.
Do not store the power tool and accessories in the
case when wet!
Don’t bend the flexible drive shaft!
When the safety clutch responds, switch off the
machine immediately!
Do not overload the motor for a long period. Engine
noise should be regular (not wave-like). Unsteady
engine performance can be perceived acoustically.
Take a break when the machine is heated up
strongly and let it cool down again. To that let the
motor idle at top speed for some time.
Ensure sufficient cable clearance. Use only exten-
sion cables permitted for outdoor use.
Keep the carry case out of reach of children. Chil-
dren may suffocate or be strangled when playing
with the carry case.
Emission levels
NOTE! Values for the A-weighted sound pressure
level and for the total vibration values can be found
in the “Technical specifications” table at page 4.
The vibration emission level given in this infor-
mation sheet has been measured in accordance
with a standardized test and may be used to com-
pare one tool with another. It may be used for a
preliminary assessment of exposure.
CAUTION! The indicated measurements refer to
new power tools. Daily use causes the noise and vi-
bration values to change.
The declared vibration emission level represents
the main applications of the tool. However, if the
tool is used for different applications, with differ-
ent accessories or poorly maintained, the vibration
emission may differ. This may significantly in-
crease the exposure level over the total working
period. However, if the tool is used for different ap-
plications, with different accessories or poorly
maintained, the vibration emission may differ. This
may significantly decrease the exposure level over
the total working period.
Additional safety measures to protect against vi-
brations may be necessary.
CAUTION! The noise produced during work
may damage your hearing.
Wear ear protection!
