When using rotary files, cut-off wheels, high-speed cutters or tungsten carbide
cutters, always 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.
Safety Warnings
•
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 cut-off
wheel. Abrasive cut-off wheels are intended for peripheral grinding, side forces
applied to these wheels may cause them to shatter.
•
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.
•
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.
•
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.
•
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.
•
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.
•
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.
•
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.
•
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.
•
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.
•
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.
