j) Hold power tool by insulated gripping
surfaces only, when performing an operation
where the cutting accessory may contact
hidden wiring or its own cord. Cutting accessory
contacting a "live" wire may make exposed metal
parts of the power tool "live" and shock the oper-
ator.
k) Position the cord clear of the spinning acces-
sory. If you lose control, the cord may be cut or
snagged and your hand or arm may be pulled into
the spinning accessory.
I) Never lay the power tool down until the
accessory 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 powdered
metal may cause electrical hazards.
o) Do not operate the power tool near flam-
mable 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.
4.2 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
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 firm grip on the power tool and
position your body and arm to allow you to
resist kickback forces. Always use the 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.

b) Never place your hand near the rotating
accessory. Accessory may kickback over your
hand.
c) 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 move-
ment 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
frequent kickback and loss of control.
4.3 Safety Warnings Specific for Sanding
Operations:
a) 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 snag-
ging, tearing of the disc or kickback.
4.4 Safety Warnings Specific for Polishing:
Loose parts on the polishing guard, especially
the fastening cords, are not permitted. Tuck
away or shorten the fastening cords. Loose,
spinning fastening cords may make contact with
your fingers or become caught in the workpiece.
---------------------------------------------------------
Use elastic cushioning layers if they have been
supplied with the abrasive and if required.
Observe the specifications of the tool or accessory
manufacturer!
Accessories must be stored and handled with care
in accordance with the manufacturer's instruc-
tions.
Ensure that accessories are installed in accord-
ance with the manufacturer's instructions.
The tool continues running after the machine has
been switched off.
When sanding and working with the lambskin
polishing disc with cord drive always work with the
hand protection guard installed.
Do not use separate reducing bushings or
adapters to adapt tools with a large hole.
The tool must lay flat and be secured against slip-
ping, e.g. using clamps. Large workpieces must be
sufficiently supported.
If accessories with threaded inserts are used, the
end of the spindle may not touch the base of the
