General power tool safety warnings
General power tool safety warnings
workpiece allows you to use your hand(s) to
control the tool. Round material such as dowel
rods, pipes or tubing have a tendency to roll
while being cut, and may cause the bit to bind
or jump toward you.
m)
Position the cord clear of the spinning
accessory.
If you lose control, the cord may
be cut or snagged and your hand or arm may
be pulled into the spinning accessory.
n)
Never lay the power tool down until
the accessory has come to a complete
stop.
The spinning accessory may grab the
surface 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 vio-
lently thrown.
p)
Do not run the power tool while car-
rying it at your side.
Accidental contact
with the spinning accessory could snag your
clothing, 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 pow-
dered metal may cause electrical hazards.
r)
Do not operate the power tool near
flammable materials.
Sparks could ignite
these materials.
s)
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 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 al-
low 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 direc-
tion 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 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.
