f )
Do not use worn down wheels from larger power
tools.
Wheel intended for larger power tool is not
suitable for the higher speed of a smaller tool and
may burst.
Additional Safety Warnings Specific for
Abrasive Cutting‑Off Operations
a )
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.
b )
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.
c )
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.
d )
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.
e )
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.
f )
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
a )
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.
Safety Warnings Specific for Wire
Brushing Operations
a )
Be aware that wire bristles are thrown by the
brush even during ordinary operation. Do not
overstress the wires by applying excessive load to
movement at the point of pinching. Abrasive wheels may also
break under these conditions.
Kickback is the result of 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 auxiliary handle, if
provided, for maximum control over kickback or
torque reaction during start up.
The operator can
control torque reaction 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
power tool will move if kickback occurs.
Kickback
will propel the tool in direction opposite to the 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.
Safety Warnings Specific for Grinding and
Abrasive Cutting‑Off Operations
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 center depressed wheels
must not be mounted below the plane of the
guard lip.
An improperly mounted 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 the operator from
broken wheel fragments, accidental contact with wheel
and sparks that could ignite clothing.
d )
Wheels must be used only for recommended
applications. For example: do not grind with the
side of cut‑off wheel.
Abrasive cut-off wheels 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
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.
