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
violently thrown.
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.
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.
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.
Store accessories in a cool dry place and
•
avoid freezing. Before use check accessory
for cracks and fractures, do not use if damage
is suspected.
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.
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.
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 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.
When using rotary files, cut-off wheels,
•
high-speed cutters or tungsten carbide
cutters, always have the workpiece
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.
