the workpiece, the rim of the grinder which comes into contact
with the piece may cut into the surface of the material, causing
the grinder to jump or come off. The grinder can jump towards to
operator or in the opposite direction, depending on the direction
of the grinder movement when it jams. The abrasive grinders
can also break in these conditions.
Kickback is the result of misuse of the power tool or of incorrect
procedures or conditions of usage, and can be avoided by taking
proper precautions as specified below.
a) Firmly grip the tool and place your body and your arms in
such a position so as to resist the force of the kickback.
Always use the auxiliary handgrip, if present, to have
maximum control over kickback or torque reaction during
start-up.
The operator can control torque reactions and
kickbacks if the appropriate precautions have been taken.
b) Never put your hands near the rotating part
– kickback from
the part can cause injury to your hand.
c) Do not place yourself in the area towards which the power
tool will move in case of kickback.
The backlash will push
the tool in the opposite direction to that of the grinder at the
moment of entanglement.
d) Take particular care when working on corners, sharp edges,
etc. Avoid making the part jump or catch.
Corners, sharp
edges or jumps have a tendency to trap the rotating part and
cause loss of control or kickback.
e) Do not connect the blade of a chainsaw for woodwork, or
the blade of a toothed saw to the power tool.
Such blades
cause frequent kickback and loss of control.
SAFETY INSTRUCTIONS FOR GRINDING
AND ABRASIVE CUT-OFF OPERATIONS
a) Use only types of grinding wheel that are compatible with
your electric tool and the specific protection of the grinding
wheel of your choice.
The grinding wheels which were not
conceived for your power tool cannot be adequately protected
and are not safe.
b) The protection must be firmly fixed to the electric tool and
safely positioned so that the operator is exposed to the
grinding wheel as little as possible.
The protection allows
to protect the operator from fragments of a broken grinding
wheel and from an accidental contact with the wheel.
c) The grinding wheels must only be used for the recommen-
ded applications. For example: do not grind with the side
of the grinding wheel to cut something.
Cutting grindstones
are destined to peripheral grinding; by pushing on the sides
of these wheels, they can break.
d) Always use flanges which are not damaged and whose
shape and size are correct for the grinding wheel of your
choice.
Adequate flanges for grinding wheels support them
reducing the risk of breaking the wheel. Flanges for cutting
wheels can be different from flanges for grinding wheels.
e) Do not use used grinding wheels of bigger electrical tools.
Grinding wheels destined to bigger electrical tools are not
adequate because of the higher speed of smaller tools: the
grinding wheel can explode.
SAFETY WARNINGS
FOR CUTTING OPERATIONS
a) Do not “block” the cutting wheel or push excessively. Do
not try to make the cut excessively deep.
By pushing on the
wheel, its load increases as well as the chances of twisting
or bending the wheel while cutting and the chances of recoil
or breaking the wheel.
b) Do not stand next to the rotating wheel or behind it.
While
working, the grinding wheel separates from the body and the
possible recoil can push it and the electric tool towards you.
c) When the grinding wheel bends or when the cutting opera-
tion is interrupted for any reason, remove the power plug
of the electric tool and keep it still until the wheel stops.
Do not try to remove the cutting wheel from the cut while
it is moving or a recoil can happen.
You have to identify the
reasons why the wheel bent and take appropriate measures
so that it doesn’t happen again.
d) Do not resume the cutting operation of the working item.
Let the grinding wheel reach its maximum speed and
carefully insert it again in the cut.
If the electrical tool is
restarted while inside the working item, the grinding wheel
can stop, go back up or have a recoil.
e) Arrange a stand for the panels or any other working piece
with big size in order to minimize the risk that the wheel
gets stuck or recoils.
Big working pieces tend to bend under
their own weight. Stands must be put under the working
piece near the cutting line and near their edge on both sides
of the wheel.
f) Be careful especially when doing a “groove cut” on existing
walls or other areas that are not visible.
The jutting out
grinding wheel can cut water or gas pipes, electrical wires
or objects, events which can cause recoil.
SAFETY WARNINGS
FOR SANDING OPERATIONS
a) Do not use sandpaper which is bigger than the sanding
discs. Follow the manufacturer’s recommendations when
choosing sandpaper.
A sheet of sandpaper larger than and
extending beyond the size of the sanding pad presents a
laceration hazard and can become tangled, causing a tear in
the disc or kickback.
SAFETY WARNINGS
FOR POLISHING OPERATIONS
a) Do not allow any loose portion of the polishing cuff part
or the wires to turn freely. Secure or cut every loose wire
attachment.
Loose wires can twist and tangle around your
fingers or get stuck in the workpiece.
SAFETY WARNINGS
FOR OPERATIONS WITH THE METAL BRUSH
a) Note that the brush, even during normal operation, emits
metal bristles. Do not apply excessive force to the wires by
applying excessive weight on the brush.
The wire bristles
can easily penetrate light clothing and/or skin.
b) If it is recommended to use protective equipment for wire
brushing, do not allow this to interfere with the metal wire disc
or the wire brush in any way.
The metal wire disc or the brush
may expand in diameter due to workload and centrifugal forces.
SAFETY WARNINGS
FOR THE ANGLE GRINDER
a) Wear eye protection when using the angle grinder.
Small
parts could strike you, causing permanent damage to your
eyes and vision.
b) Always use the accessory hand grip(s) provided with the
tool.
Loss of control can cause personal injuries.
c) Before installing or removing accessories (discs, etc.),
unplug the device.
Any maintenance must be performed safely
in order to prevent accidents caused by an unexpected start.
d) If the electricity isn’t available (i.e. because of a malfun-
ction, an interruption by the supplying company because
of works, an accidental removal of the plug, etc.) the tool
must be switched off (“OFF – O”).
This way an accidental
restart of the tool will be prevented.
