Kickback And Related Warnings - Makita SG150 Traducción De Las Instrucciones De Manejo Originales

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 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
filtrating 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
wheel may fly away and cause injury beyond
immediate area of operation.
k) 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.
l) 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 wheel.
m) 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.
n) 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.
o) 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.
p) Do not operate the power tool near
flammable materials.
Sparks could ignite these materials.
q) Do not use accessories that require liquid
coolants.
Using water or other liquid coolants may result in
electrocution or shock.
2.6.2 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.
Overstressing the wheel increases the loading
and susceptibility to twisting or binding of the
wheel in the cut and the possibility of kickback
or wheel breakage.
