Kickback And Related Warnings - Narex EBU 125-12 C Originalbetriebsanleitung

English
Cutting accessory contacting a "live" wire may make ex-
posed metal parts of the power tool "live" and shock the
operator.
k) Position the cord clear of the spinning accessory. If
you lose control 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 con-
trol.
m) 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.
n) 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.
o) Do not operate the power tool near flammable materi‑
als. Sparks could ignite these materials.
p) Do not use accessories that require liquid coolants. Us-
ing water or other liquid coolants may result in electrocu-
tion or shock.

Kickback and Related Warnings

Kickback is a sudden reaction to a pinched or snagged rotating
wheel, backing 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 to-
ward 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 an auxiliary handle, if provided, for
maximum control over kickback or torque reaction
during start‑up. The operator can control torque reac-
tions or kick-back forces, if proper precautions are taken.
b) Never place your hand near the rotating accessory. Ac-
cessory 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. Cor-
ners, sharp edges or bouncing have a tendency to snag
the rotating accessory and cause loss of control or kick-
back.
e) Do not attach a saw chain woodcarving blade or
toothed saw blade. Such blades create frequent kick-
back 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 se‑
lected wheel. Wheels for which the power tool was not
designed cannot be adequately guarded and are unsafe.
20
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 opera‑
tor. 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 applica‑
tions. For example: do not grind with the side of cut‑off
wheel. Abrasive cut-off wheels are intended for peripher-
al grinding, side forces applied to these wheels may cause
them to shatter.
d) Always use undamaged wheel flanges that are of cor‑
rect size and shape for your selected wheel. Proper
wheel flanges support the wheel thus reducing the pos-
sibility 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 pres‑
sure. 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.
b) Do not position your body in line with and behind the
rotating wheel. When the wheel, at the point of opera-
tion, is moving away from your body, the possible kick-
back 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 com‑
plete 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 ac-
tion 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 mini‑
mise the risk of wheel pinching and kick‑back. Large
workpieces tend to sag under their own weight. Supports
must be placed under the workpiece 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 ex‑
isting 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 select‑
ing sanding paper. Larger sanding paper extending be-
yond the sanding pad presents 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 during ordinary operation. Do not overstress the
wires by applying excessive load to the brush. The wire
bristles can easily penetrate light clothing and/or skin.
b) If the use of a guard is recommended for wire brush‑
