performing an operation where
the cutting accessory may contact
hidden wiring or its own cord.
Cutting
accessory contacting a “live” wire may
make exposed metal parts of the power
tool “live” and could give the operator an
electric shock.
m) Position the cord clear of the spinning
accessory.
lf you lose control, the cord
may be cut or snagged and your hand or
arm may be pulled into the spinning wheel.
n) Never lay the power tool down until
the accessory has come to a complete
stop.
The spinning wheel may grab the
surface and pull the power tool out of your
control.
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. 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 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. 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 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
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, segmented
diamond wheel with a peripheral
gap greater than 10mm or toothed
saw blade.
Such blades create frequent
kickback and loss of control.
f) Do not “jam” the 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.
g) 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 wheel
from the cut while the wheel is in
motion otherwise kickback may occur.
lnvestigate and take corrective action to
eliminate the cause of wheel binding.
h) Do not restart the cutting operation
