ROTARY TOOL SAFETY WARNINGS

Maintain a firm grip on the power tool and position
your body and arm to allow you to resist kickback
forces.
The operator can control torque reactions or
kickback forces, if proper precautions are taken.

Use special care when working corners, sharp edges,
etc. Avoid bouncing and snagging the accessory.
Corners, sharp edges or bouncing have a tendency to
snag the rotating accessory and cause loss of control or
kickback.


Do not attach a toothed saw blade. Such blades create
frequent kickback and loss of control.
 
Always feed the bit into the material in the same
direction as the cutting edge is exiting from the
material (which is the same direction as the chips are
thrown).
Feeding the tool in the wrong direction causes
the cutting edge of the bit to climb out of the work and
pull the tool in the direction of this feed.

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 SPECIFIC FOR
GRINDING AND ABRASIVE CUTTING-OFF
OPERATIONS:

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.

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.
SAFETY WARNINGS SPECIFIC FOR WIRE
BRUSHING OPERATIONS:

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.
