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 operations, 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 re-enter 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
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 and centrifugal forces.
Additional Safety Warnings for Grinders
• Threaded mounting of accessories must match the grinder spindle
thread. For accessories mounted by flanges, the arbour hole of the
accessory must fit the locating diameter of the flange. Accessories
that do not match the mounting hardware of the power tool will run
out of balance, vibrate excessively and may cause loss of control.
• The grinding surface of the center depressed wheels must 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.
• Air vents often cover moving parts and should be avoided.
Loose clothes, jewelry or long hair can be caught in moving parts.
