sory.
o)
The spinning accessory may grab the sur-
face and pull the power tool out of your con-
trol.
p)
devices can unexpectedly shift, causing
loss of control, loose rotating components
will be violently thrown.
q)
Accidental contact with the
spinning accessory could snag your cloth-
ing, pulling the accessory into your body.
r)
The motor's fan will draw the dust in-
side the housing and excessive accumula-

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 move-
ment 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 con-
ditions and can be avoided by taking proper
precautions as given below.
a)
tor can control kickback forces, if proper
precautions are taken.
b)
edges or bouncing have a tendency to snag
the rotating accessory and cause loss of
control or kickback.
c)
blades create frequent kickback and loss of
control.
d)
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 direc-
tion of this feed.
e)
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.
