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 powdered 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.
FURTHER SAFETY
INSTRUCTIONS FOR ALL
OPERATIONS
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
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 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 direction 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 become 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.
SAFETY WARNINGS
SPECIFIC FOR GRINDING
AND ABRASIVE CUTTING-OFF
OPERATIONS:
a) Use only wheel types that are recommended
for your power tool and only for recommended
applications. For example: do not grind with the
side of a cut-off wheel.
Abrasive cut-off wheels
are intended for peripheral grinding, side forces
applied to these wheels may cause them to
shatter.
b) For threaded abrasive cones and plugs use
only undamaged wheel mandrels with an
unrelieved shoulder flange that are of correct
size and length.
Proper mandrels will reduce the
possibility of breakage.
c) Do not “jam” a cut-off 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 snagging of the wheel in the cut and the
possibility of kickback or wheel breakage.
d) Do not position your hand in line with and
behind the rotating wheel. When the wheel,
at the point of operation, is moving away from
your hand, the possible kickback may propel the
spinning wheel and the power tool directly at you.
e) When wheel is pinched, snagged 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 cut-off
wheel from the cut while the wheel is in motion
otherwise kickback may occur.
Investigate and
take corrective action to eliminate the cause of
wheel pinching or snagging.
f) Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and
