Kickback And Related Warnings - Metabo HPT GP 10DL Instructions De Sécurité Et Mode D'emploi

k) Hold power tool by insulated gripping
surfaces only,
operation where the cutting accessory may
contact hidden wiring.
Cutting accessory contacting a "live" wire may
make exposed metal parts of the power tool
"live" and could give the operator an electric
shock.
l) Always hold the tool fi rmly in your hand(s)
during the start-up.
The reaction torque of the motor, as it
accelerates to full speed, can cause the tool to
twist.
m) Use clamps
whenever practical. Never hold a small
workpiece in one hand and the tool in the
other hand while in use.
Clamping a small 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.
n) 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.
o) 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.
p) 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.
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
fl ammable materials.
Sparks could ignite these materials.
t) Do not use accessories that require liquid
coolants.
Using water or other liquid coolants may result
in electrocution or shock.

KICKBACK AND RELATED
an
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 fi rm 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 fi les, 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 fi le, high-speed cutter or
