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 force 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.
f) Do not use worn down wheels from larger power tools. Wheels intended for larger
power tools are not suitable for the higher speed of a smaller tool and may burst.
4.4 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
excessively deep cuts. 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.
4.5 Safety Warnings Specific for Sanding Operations:
Do not use excessively oversized sanding disc paper. Follow manufacturer's recom-
mendations 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.
4.6 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 interfe-
rence of the wire wheel or brush with the guard. Wire wheel or brush may expand in
diameter due to work load and centrifugal forces.
