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 startup. The operator can control torque
reactions or kickback forces, if proper precautions are
taken.
Never place your hand near the rotating accessory.
The accessory may kickback over your hand.
Do not position your body in the area where the
power tool will move if kickback occurs.
Kickback
will propel the tool in the direction opposite to the
wheel’s movement at the point of snagging.
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.
Do not attach a saw chain woodcarving blade or
toothed saw blade. Such blades create frequent
kickback and loss of control over the power tool.
Additional safety instructions for grinding and cu-
tting off operations
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.
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.
Wheels must be used only for recommended
applications. For example: do not grind with the
side of the cut-off wheel. Abrasive cut-off wheels
are intended for peripheral grinding; side forces
applied to these wheels may cause them to
shatter.
Always use undamaged wheel flanges that
are of correct size and shape for your selected wheel.
Proper wheel flanges support the wheel thus reducing
the possibility of wheel breakage. Flanges for cut-off
wheels may be different from grinding wheel flanges.
Do not use worn down wheels from larger power
tools. Wheels intended for larger power tools are not
suitable for the higher speed of a smaller tool and may
burst.
Additional safety warnings specific for abrasive
cutting off operations
Do not “jam” the cut-off wheel or apply excessive
pressure. Do not attempt to make an excessive
depth of cut. Overstressing the wheel increases
the loading and susceptibility to twisting or binding of
the wheel in the cut and the possibility of kickback or
wheel breakage.
Do not position your body in line with and behind
the rotating wheel. When the wheel, at the point of
operation, is moving away from your body, the possible
kickback may propel the spinning wheel and the power
tool directly at you.
When wheel is binding or when interrupting a cut
for any reason, switch off the power tool and hold
the power tool motionless until the wheel comes
to a complete stop. Never attempt to remove the cut-
off wheel from the cut while the wheel is in motion,
otherwise kickback may occur. Investigate and take
corrective action to eliminate the cause of wheel
binding.
Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and
carefully reenter the cut. The wheel may bind, walk
up or kickback if the power tool is restarted in the
workpiece.
Support panels or any oversized workpiece to
minimize the risk of wheel pinching and kickback.
Large workpieces tend to sag under their own weight.
Supports must be placed under the workpiece near
the line of cut and near the edge of the workpiece on
both sides of the wheel.
Use extra caution when making a “pocket cut” into
existing walls or other blind areas. The protruding
wheel may cut gas or water pipes, electrical wiring or
objects that can cause kickback.
Safety warnings specific for sanding operations
Do not use excessively oversized sanding disc
paper. Follow manufacturers recommendations,
when selecting sanding paper. Larger sanding
paper extending beyond the sanding pad presents a
laceration hazard and may cause snagging, tearing of
the disc, or kickback.
Avvertenze di pericolo specifiche per lavori di levi -
gatura con carta vetro
Non utilizzare mai fogli abrasivi troppo grandi ma
attenersi alle indicazioni del rispettivo produttore
relative alle dimensioni dei fogli abrasivi. Fogli
abrasivi che dovessero sporgere oltre il platorello
possono provocare incidenti oppure blocchi, strappi
dei fogli abrasivi oppure contraccolpi.
Safety warnings specific for wire brushing
operations
Be aware that wire bristles are thrown by the brush
even during ordinary operation. Do not overstress
the wires by applying excessive load to the brush.
The wire bristles can easily penetrate light clothing
and/or skin.
