have the work securely clamped. These wheels will
grab if they become slightly canted in the groove, and
can kickback. When a cut-off wheel grabs, the wheel
itself usually breaks. When a rotary file, high-speed
cutter or tungsten carbide cutter grabs, it may jump
from the groove and you could lose control of the tool.
ADDITIONAL SAFETY INSTRUCTIONS FOR
GRINDING AND CUTTING-OFF OPERATIONS
SAFETY WARNINGS SPECIFIC FOR
GRINDING AND ABRASIVE CUTTING-OFF
OPERATIONS
a) Use only wheel types that are recommended
for your power tool and only for recommended
applications. For example: do not grind with the
side of a cut-off wheel.
Abrasive cut-off wheels are
intended for peripheral grinding, side forces applied to
these wheels may cause them to shatter.
b) For threaded abrasive cones and plugs use only
undamaged wheel mandrels with an unrelieved
shoulder flange that are of correct size and length.
Proper mandrels will reduce the possibility of breakage.
c) Do not “jam” a 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 snagging of the
wheel in the cut and the possibility of kickback or wheel
breakage.
d) Do not position your hand in line with and behind
the rotating wheel.
When the wheel, at the point of
operation, is moving away from your hand, the possible
kickback may propel the spinning wheel and the power
tool directly at you.
e) When wheel is pinched, snagged 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 pinching or snagging.
f) Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and
carefully re-enter the cut.
The wheel may bind,
walk up or kickback if the power tool is restarted in the
workpiece.
g) 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.
h) 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.
ADDITIONAL SAFETY INSTRUCTIONS FOR
WIRE BRUSHING OPERATIONS
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) Allow brushes to run at operating speed for at
least one minute before using them. During this
time no one is to stand in front or in line with the
brush.
Loose bristles or wires will be discharged during
the run-in time.
c) Direct the discharge of the spinning wire brush
away from you.
Small particles and tiny wire
fragments may be discharged at high velocity during
the use of these brushes and may become imbedded in
your skin.
