Kickback And Related Warnings - Narex EBU 23-24 C Instrucciones De Uso

j) 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 con-
tacting a "live" wire may make exposed metal parts of the power tool
"live" and shock the operator.
k) Position the cord clear of the spinning accessory. If you lose con-
trol of the power tool, the cord may be cut or snagged and your hand
or arm may be pulled into the spinning accessory.
l) Never lay the power tool down until the accessory has come to
a complete stop. The spinning accessory may catch the surface and
pull the power tool out of your control.
m) Do not run the power tool while carrying it at your side. Acci-
dental contact with the spinning accessory could snag your clothing,
pulling the accessory into your body.
n) Regularly clean the power tool's air vents. The motor's fan will
draw the dust inside the housing and excessive accumulation of pow-
dered metal may cause electrical hazards.
o) Do not operate the power tool near flammable materials.
Sparks could ignite these materials.
p) 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, back-
ing pad, 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
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 pro-
cedures 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
an auxiliary handle, if provided, for maximum control over
kickback or torque reaction during start-up. The operator can
control torque reactions or kick-back 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 the area where power tool will
move if kickback occurs. Kick-back will propel the tool in direction
opposite to the wheel's movement at the point of snagging.
d) Take 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 or toothed saw
blade. Such blades create frequent kickback and loss of control.
Safety warnings specific for grinding and
cutting-off operations:
a) Use only wheel types that are recommended for your power
tool and the specific guard designed for the selected wheel.
Wheels for which the power tool was not designed cannot be ad-
equately guarded and are unsafe.
b) Use only the specific guard designed for the selected wheel.
The guard must be securely attached to the power tool and
positioned for maximum safety, so the least amount of wheel
is exposed towards the operator. The guard helps to protect the
operator from broken wheel fragments and accidental contact with
the wheel.
c) Wheels must be used only for recommended applications. For
example: do not grind with the side of cut-off wheel. Abrasive
cut-off wheels are intended for peripheral grinding, side forces ap-
plied to these wheels may cause them to shatter.
d) Always use undamaged wheel flanges that are of correct size
and shape for your selected wheel. Proper wheel flanges support
the wheel thus reducing the possibility of wheel breakage. Flanges for
cut-off wheels may be different from grinding wheel flanges.
e) Do not use worn down wheels from larger power tools. Wheels
intended for larger power tools are not suitable for the higher speed
of a smaller tool and may burst.
Additional safety instructions for cutting-off
operations:
a) Do not "jam" the cut-off 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 break-
age.
b) Do not position your body in line with and behind the rotating
wheel. When the wheel, at the point of operation, is moving away
from your body, the possible kickback may propel the spinning wheel
and the power tool directly at you.
c) When wheel is binding or when interrupting a cut for any
reason, switch off the power tool and hold the power tool
motionless until the wheel comes to a complete stop. Never
attempt to remove the cut-off wheel from the cut while the
wheel is in motion otherwise kick-back may occur. Investigate
and take corrective action to eliminate the cause of wheel binding.
d) Do not restart the cutting operation in the workpiece. Let the
wheel reach full speed and carefully reenter the cut. The wheel
may bind, walk up or kickback if the power tool is restarted in the
workpiece.
e) Support panels or any oversized workpiece to minimise the
risk of wheel pinching and kick-back. Large workpieces tend to
sag under their own weight. Supports must be placed under the work-
piece near the line of cut and near the edge of the workpiece on both
sides of the wheel.
f) Take extra caution when making a "pocket cut" into existing
walls or other blind areas. The protruding wheel may cut gas or
water pipes, electrical wiring or objects that can cause kickback.
Safety Warnings Specific for Sanding Operations:
a) Do not use excessively oversized sanding disc paper. Follow
manufacturers recommendations when selecting sanding pa-
per. Larger sanding paper extending beyond the sanding pad pres-
ents a laceration hazard and may cause snagging, tearing of the disc
or kickback.
Safety Warnings Specific for Wire Brushing
Operations:
a) Be aware that wire bristles are thrown by the brush even dur-
ing ordinary operation. Do not overstress the wires by apply-
ing excessive load to the brush. The wire bristles can easily pen-
etrate light clothing and/or skin.
b) If the use of a guard is recommended for wire brushing, do
not allow any interference of the wire wheel or brush with the
guard. Wire wheel or brush may expand in diameter due to work
load and centrifugal forces.
