n. Never lay the power tool down until the
accessory has come to a complete stop.
The spinning accessory may grab the sur-
face and pull the power tool out of your
control.
o. After changing the bits or making any
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.
p. Do not run the power tool while carrying
it at your side. Accidental contact with the
spinning accessory could snag your cloth-
ing, pulling the accessory into your body.
q. 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.
r. Do not operate the power tool near flam-
mable materials. Sparks could ignite these
materials.
s. Do not use accessories that require liquid
coolants. Using water or other liquid cool-
ants may result in electrocution or shock.
t. Use only in well-ventilated area. Working
in a safe environment reduces risk of in-
jury.
u. Allow for sufficient space, at least 6"
(15.2cm), between your hand and the
spinning bit. Do not reach in the area of
the spinning bit. The proximity of the spin-
ning bit to your hand may not always be
obvious.
v. Do not touch the bit or collet after use.
After use the bit and collet are too hot to
be touched by bare hands.
w. Do not alter or misuse tool. Any alteration
or modification is a misuse and may result
in serious personal injury.
2. 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 acces-
sory which in turn causes the uncontrolled

power tool to be forced in the direction op-
posite 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 caus-
ing the wheel to climb out or kickout. 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 opera-
tor 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 di-
rection 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 be-
come 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.
