Kickback And Related Warnings - Metabo HPT GP 2S2 Instructions De Sécurité Et Mode D'emploi

e) The outside diameter and the thickness of your
accessory must be within the capacity rating of
your power tool.
Incorrectly sized accessories cannot be adequately
controlled.
f) The arbour size of wheels, sanding drums or any
other accessory must properly fi t the spindle or
collet of the power tool.
Accessories that do not match the mounting hardware
of the power tool will run out of balance, vibrate
excessively and may cause loss of control.
g) Mandrel mounted wheels, sanding drums,
cutters or other accessories must be fully
inserted into the collet or chuck.
If the mandrel is insuffi ciently held and/or the
overhang of the wheel is too long, the mounted wheel
may become loose and be ejected at high velocity.
h) Do not use a damaged accessory. Before each
use inspect the accessory such as abrasive
wheels for chips and cracks, sanding drum for
cracks, tear or excess wear, wire brush for loose
or cracked wires. If power tool or accessory
is dropped, inspect for damage or install an
undamaged accessory. After inspecting and
installing an accessory, position yourself and
bystanders away from the plane of the rotating
accessory and run the power tool at maximum
no-load speed for one minute.
Damaged accessories will normally break apart
during this test time.
i) Wear personal protective equipment. Depending
on application, use face shield, safety goggles or
safety glasses. As appropriate, wear dust mask,
hearing protectors, gloves and workshop apron
capable of stopping small abrasive or workpiece
fragments.
The eye protection must be capable of stopping
fl ying debris generated by various operations. The
dust mask or respirator must be capable of fi ltrating
particles generated by your operation. Prolonged
exposure to high intensity noise may cause hearing
loss.
j) Keep bystanders a safe distance away from work
area. Anyone entering the work area must wear
personal protective equipment.
Fragments of workpiece or of a broken accessory
may fl y away and cause injury beyond immediate area
of operation.
k) Hold power tool by insulated gripping surfaces
only, when performing an operation where the
cutting accessory may contact hidden wiring or
its own cord.
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 to support workpiece 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 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.
