sory. If you lose control, the cord may be cut or
snagged and your hand or arm may be pulled
into the spinning accessory.
o) Never lay the power tool down until the acces­
sory has come to a complete stop. The spinning
accessory may grab the surface and pull the
power tool out of your control.
p) After changing the bits or making any adjust­
ments, make sure the collet nut, chuck or any
other adjustment devices are securely tighte­
ned.
Loose adjustment devices can unexpected-
ly shift, causing loss of control, loose rotating
components will be violently thrown.
q) 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.
r)
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.
s) Do not operate the power tool near flammable
materials.
Sparks could ignite these materials.
t) Do not use accessories that require liquid cool­
ants.
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 cau-
ses 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 pin-
ched by the workpiece, the edge of the wheel that is
entering into the pinch point can dig into the surfa-
ce 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 in-
correct 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, cut­off 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.
ADDITIONAL SAFETY INSTRUCTIONS FOR
GRINDING AND CUTTING-OFF OPERATIONS
Safety warnings specific for grinding and abrasive
cutting­off 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 cut­off 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 possibi-
lity of breakage.
c) Do not “jam” a cut­off 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 possi-
bility 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 inter­
rupting a cut for any reason, switch off the power
