Kickback and related warnings
Kickback is a sudden reaction to a pinched or snagged
rotating wheel. Pinching or snagging causes rapid
stalling of the rotating wheel which in turn causes the
uncontrolled power tool to be forced in the direction
opposite of the wheel’s rotation at the point of the
binding.
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 con-
ditions.
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. Al-
ways use auxiliary handle, if provided,
for maximum control over kickback or
torque reaction during start-up.
The op-
erator can control torque reactions or kickback
forces, if proper precautions are taken.
b) Never place your hand near the rotat-
ing accessory.
Accessory may kickback over
your hand.
c) Do not position your body in line with
the rotating wheel.
Kickback will propel
the tool in direction opposite to the wheel’s
movement at the point of snagging.
d) Use special care when working cor-
ners, 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, woodcarv-
ing blade, segmented diamond wheel
with a peripheral gap greater than
10 mm or toothed saw blade.
Such blades
create frequent kickback and loss of control.
f) Do not “jam” the wheel or apply ex-
cessive pressure. Do not attempt to
make an excessive depth of cut.
Over-
stressing 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.
g)
When wheel is binding or when inter-
rupting 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 wheel from the cut while
the wheel is in motion otherwise kick-
back may occur.
Investigate and take cor-
rective action to eliminate the cause of wheel
binding.
h)
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.
i) Support panels or any oversized work-
piece 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.
j)
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.
