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.
Never lay the power tool down until the acces-
sory has come to a complete stop.
The spin-
ning accessory may grab the surface and pull
the power tool out of your control.
After changing the bits or making any adjust-
ments, make sure the collet nut, chuck or any
other adjustment devices are securely tight-
ened.
Loose adjustment devices can unex-
pectedly shift, causing loss of control, loose
rotating components will be violently thrown.
Do not run the power tool while carrying it at
your side.
Accidental contact with the spin-
ning accessory could snag your clothing, pull-
ing the accessory into your body.
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.
Do not operate the power tool near flammable
materials.
Sparks could ignite these materials.
Do not use accessories that require liquid
coolants.
Using water or other liquid coolants
may result in electrocution or shock.
Further safety warnings for all appli-
cations
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.
Maintain a firm grip on the power tool and
position your body and arm to allow you to
resist kickback forces.
The operator can con-
trol kickback forces, if proper precautions are
taken.
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.
Do not attach a toothed saw blade.
Such
blades create frequent kickback and loss of
control.
Always feed the bit into the material in the
same direction as the cutting edge is exiting
from the material (which is the same direc-
tion 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.
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.
Additional safety instructions for
grinding and cutting-off operations
Safety warnings specific for grinding
and abrasive cutting-off operations:
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.
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.
