adjustments, make sure the collet nut,
chuck or any other adjustment devices
are securely tightened. Loose adjustment
devices can unexpectedly shift, causing loss
of control, loose rotating components will be
violently thrown.
o. Do not run the power tool while carrying
it at your side. Accidental contact with the
spinning accessory could snag your clothing,
pulling the accessory into your body.
p. Regularly clean the power tool's air vents.
The motor's fan will draw the dust inside
the housing and excessive accumulation of
powdered metal may cause electrical hazards.
q. Do not operate the power tool near
flammable materials. Sparks could ignite
these materials.
r. Do not use accessories that require liquid
coolants. Using water or other liquid coolants
may result in electrocution or shock.
KICKBACK AND RELATED WARNINGS
Kickback is a sudden reaction to a pinched or
snagged rotating wheel, sanding band, brush or
any other accessory. Pinching or snagging causes
rapid stalling of the rotating accessory which in
turn causes the uncontrolled power tool to be
forced in the direction opposite of the accessory's
rotation.
For example, if an abrasive wheel is snagged or
pinched by the workpiece, the edge of the wheel
that is entering into the pinch point can dig into
the surface of the material causing the wheel to
climb out or kick out. The wheel may either jump
toward or away from the operator, depending on
direction of the wheel's movement at the point of
pinching. Abrasive wheels may also break under
these conditions.
Kickback is the result of power tool misuse and/or
incorrect operating procedures or conditions and
can be avoided by taking proper precautions as
given below.
a. 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 kickback forces, if proper precautions
are taken.
b. 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.
c. Do not attach a toothed saw blade. Such
blades create frequent kickback and loss of
control.
d. 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.
e. 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
a. 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.
b. 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.
c. 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.
d. 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.
e. 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.
f. 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.
g. 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.
h. 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
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. 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
