Metabo HPT CC 12Y Manual De Instrucciones página 5

Incorrectly sized accessories cannot be adequately
guarded or controlled.
h) The arbour size of wheels and flanges must
properly fi t the spindle of the power tool.
Wheels and flanges with arbour holes that do not
match the mounting hardware of the power tool will
run out of balance, vibrate excessively and may
cause loss of control.
i) Do not use damaged wheels. Before each use,
inspect the wheels for chips and cracks. If power
tool or wheel is dropped, inspect for damage or
install an undamaged wheel. After inspecting
and installing the wheel, position yourself and
bystanders away from the plane of the rotating
wheel and run the power tool at maximum no
load speed for one minute.
Damaged wheels will normally break apart during
this test time.
j) Wear personal protective equipment. Depending
on application, use face shield, safety goggles
or safety glasses. As appropriate, wear dust
mask, hearing protectors, gloves and shop
apron capable of stopping small abrasive or
workpiece fragments.
The eye protection must be capable of stopping
flying 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.
k) 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 wheel may
fl y away and cause injury beyond immediate area of
operation.
l) Hold the 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.
m) Po s i t i o n t h e c o rd c l e a r o f t h e s p i n n i n g
accessory.
If you lose control, the cord may be cut or snagged
and your hand or arm may be pulled into the spinning
wheel.
n) Never lay the power tool down until the
accessory has come to a complete stop.
The spinning wheel may grab the surface and pull
the power tool out of your control.
o) 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.
p) 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.
q) Do not operate the power tool near flammable
materials.
Sparks could ignite these materials.
r) 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. Pinching or snagging causes rapid stalling
of the rotating wheel which in turn causes the uncontrolled
power tool to be forced in the direction opposite of the
wheel's rotation at the point of the binding.
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 firm grip on the power tool and
position your body and arm to allow you to resist
kickback forces. Always use auxiliary handle, if
provided, for maximum control over kickback or
torque reaction during start-up.
The operator can control torque reactions or kickback
forces, if proper precautions are taken.
b) Never place your hand near the rotating
accessory.
Accessory may kickback over your hand.
c) Do not position your body in line with the
rotating wheel.
Kickback will propel the tool in direction opposite to
the wheel's movement at the point of snagging.
d) 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.
e) Do not attach a saw chain, woodcarving blade,
segmented diamond wheel with a peripheral gap
greater than 10 mm or toothed saw blade.
Such blades create frequent kickback and loss of
control.
f) Do not "jam" the wheel or apply excessive
pressure. Do not attempt to make an excessive
depth of cut.
