sory may contact hidden wiring or its own cord. A cutting
accessory that comes in contact with a "live" wire may
render exposed metal parts of the power tool "live" and
give the operator an electric shock.
l) 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 accessory.
m) Never lay the power tool down until the accessory
has come to a complete stop. The spinning accessory
may catch the surface and pull the power tool out of your
control.
n) 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.
o) Regularly clean the power tool's air vents. The motor's
fan draws dust into the housing.
p) Do not operate the power tool near flammable materi-
als. Sparks could ignite these materials.
q) Do not use accessories that require liquid coolants.
Using water or other liquid coolants may result in electrocu-
tion 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, depend-
ing 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 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 accessory. The
accessory may kickback over your hand.
c) Do not allow your body to enter the area where the
power tool would move if kickback occurs. Kickback
will propel the power tool in the opposite direction of the
accessory's movement at the point of jamming.
d) Use special care when working around corners, sharp
edges etc. You must prevent accessories from bouncing
off the power tool and becoming jammed. A rotating
accessory tends to jam around corners and sharp edges
and also if bouncing occurs, thus causing 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 Grinding with Diamond
Cup Wheels:
a) Use only wheel types that are recommended for
your power tool and the specific guard designed for the
selected wheel. Wheels for which the power tool was not
designed cannot be adequately guarded and are unsafe.
b) The safety guard must be securely attached to the
power tool. Always direct the power tool so that the
wheel is not openly exposed to the operator. The guard
helps to protect the operator from broken fragments,
accidental contact with the wheel and sparks that could
ignite clothing.
c) Wheels must be used only for recommended applica-
tions.
d) Always use undamaged wheel flanges that are the
correct size and shape for your selected accessories. The
correct flanges support the accessories.
4.4 Additional Safety Instructions:
WARNING– Always wear protective goggles.
Wear earprotectors.
Wear a suitable dust protection mask.
WARNING – Always operate with two hands.
Use elastic cushioning layers if they have been supplied
with the sanding media and if required.
Observe the specifications of the accessory manufacturer!
Protect the accessories from grease and physical impact.
Accessories must be stored and handled with care in accor-
dance with the manufacturer's instructions. The workpiece
must be seated firmly and be secured against slipping,
e.g. using clamps. Large workpieces must be supported
adequately.
If accessories with threaded inserts are used, the end of the
spindle may not touch the base of the hole on the grinding
tool. Make sure that the thread in the accessory is long
enough to accommodate the full length of the spindle. The
thread in the accessory must match the thread on the spin-
dle. See page 3 and chapter 14. Technical Specifications for
more information on the spindle length and thread.
