Safety Warnings Specific For Sanding Operations; Safety Warnings Specific For Polishing Operations - Dremel 300 Series Operating/ Safety Instruction

a. Maintain a firm grip on the power tool and position your
body and arm to allow you to resist kickback forces.
Always use auxiliary handle, if provided, for maximum
control over kickback or torque reaction during start-up.
The operator can control torque reactions or kickback
forces, if proper precautions are taken.
b. Never place your hand near the rotating accessory.
Accessory may kickback over your hand.
c. Do not position your body in the area where power tool
will move if kickback occurs. Kickback will propel the tool
in direction opposite to the wheel's movement at the point
of snagging.
d. 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.
e. Do not attach a saw chain woodcarving blade or toothed
saw blade. Such blades create frequent kickback and loss
of control.
SAFETY WARNINGS SPECIFIC FOR GRINDING
AND ABRASIVE CUTTING OFF OPERATIONS
a. Use only wheel types that are recommended for your
power tool and the specific guard designed for the selected
wheel. Wheels for which the power tool was not designed
cannot be adequately guarded and are unsafe.
b. 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 forces applied to these wheels may cause them to
shatter.
c. 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.
d. Do not use worn down wheels from larger power tools.
Wheel intended for larger power tool is not suitable for the
higher speed of a smaller tool and may burst.
ADDITIONAL SAFETY WARNINGS SPECIFIC
FOR ABRASIVE CUTTING OFFOPERATIONS
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 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.
SAFETY WARNINGS SPECIFIC
FOR SANDING OPERATIONS
a. When sanding, do not use excessively oversized sanding
disc paper. Follow manufacturers 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 POLISHING OPERATIONS
a. Do not allow any loose portion of the polishing bonnet or
its attachment strings to spin freely. Tuck away or trim any
loose attachment strings. Loose and spinning attachment
strings can entangle your fingers or snag on the workpiece.
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 load and centrifugal forces.
