m) Do not run the power tool while carrying it at
your side. Accidental contact with the rotating
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
flammable materials. Sparks could ignite these
materials.
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 grinding 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 abrasive wheel may either jump
toward or away from the operator, depending on
direction of the disc'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 if suitable precautionary measures
are taken as described 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 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
accessory. Accessory may kickback over your
hand.
c) Do not position your body in the area
where the power tool will move if kickback
occurs. Kickback
will propel the tool in direction opposite to the
grinding 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
frequent kickback and loss of control.
4.3 Safety Warnings Specific for Grinding
and Cut-Off Grinding:
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 grinding surface of the centre depressed
wheels must be mounted below the plane of
the guard lip. An improperly mounted grinding
wheel that projects through the plane of the guard
lip cannot be adequately protected.
c) The guard must be securely attached to the
power tool and positioned for maximum safety,
so the least amount of wheel is exposed
towards the operator. The guard helps to protect
operator from broken wheel fragments and
accidental contact with wheel and sparks which
could ignite clothing.
d) Grinding media must be used only for
recommended applications.
For example: Do not grind with the side of
cutting disc. Cutting discs are intended for
peripheral grinding. Side forces applied to these
wheels may cause them to shatter.
e) Always use undamaged wheel flanges that
are of correct size and shape for your selected
grinding wheel. Proper wheel flanges support the
grinding wheel thus reducing the possibility of
grinding wheel breakage. Flanges for cutting discs
may be different from grinding wheel flanges.
f) Do not use worn down grinding wheels from
larger power tools. Grinding wheels intended for
larger power tools are not suitable for the higher
speed of a smaller tool and may break.
4.4 Additional safety instructions:
WARNING – Always wear protective
goggles.
Check the isolation of the handle for damage prior
to use. Do not use any damaged side handles!
Use elastic cushioning layers if they have been
supplied with the sanding media and if required.
Observe the specifications of the tool or accessory
manufacturer! Protect the discs from grease or
impact!
Cup wheels must be stored and handled with care
in accordance with the manufacturer's instructions.
Do not use machines with cutting or grinding discs.
The workpiece must lay flat and be secured against
slipping, 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
hole on the sanding 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 spindle.
See page 2 and chapter 15. Technical
Specifications for more information on the spindle
length and thread.
