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 Operations:
Do not attempt to cut large stock or sheets
of metal as this machine is not designed to
be a dedicated cut-off machine.
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.
Do not use type 1 abrasive wheels designed
for straight grinding.
Safety Warnings Specific for Sanding
Operations:
a) Do not use excessively oversized sanding
disc paper. Follow manufacturer’s
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 load and
centrifugal forces.
