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 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.
c) 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.
d) 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.
e) 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 Operation
a) Do not “jam” the cut-off wheel or apply excessive pressure. Do not attempt
to make an excessive depth of cut.
Over stressing 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 the
brush.
The wire bristles can easily penetrate light clothing and/or skin.
b) If the use of a guard is recommended for wire brushing, do not allow any
interference of the wire wheel or brush with the guard.
Wire wheel or brush
may expand in diameter due to work and centrifugal forces.
