Kickback And Related Warnings - Narex ABU 125‑600 B BASIC Original Bedienungsanleitung

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 guarded or controlled.
f) The arbour size of wheels, flanges, backing pads or any other
accessory must properly fit the spindle of the power tool. Ac-
cessories with arbour holes that do not match the mounting hard-
ware of the power tool will run out of balance, vibrate excessively
and may cause loss of control.
g) Do not use a damaged accessory. Before each use inspect the
accessories such as abrasive wheels for chips and cracks, back-
ing pads for cracks, tear or excess wear, wire brushes for loose
or cracked wires. If power tool or accessory is dropped, inspect
for damage or install an undamaged accessory. After inspect-
ing and installing an accessory, position yourself and bystand-
ers away from the plane of the rotating accessory and run the
power tool at maximum no-load speed for one minute. Dam-
aged accessories will normally break apart during this test time.
h) Wear personal protective equipment. Depending on the ap-
plication, use face shield, safety goggles or safety glasses. As
appropriate, wear a dust mask, hearing protectors, gloves and
a workshop apron capable of stop-ping small abrasive or work-
piece fragments. The eye protection must be capable of stopping
flying debris generated by various operations. The dust mask or
respirator must be capable of filtering particles generated by your
operation. Prolonged exposure to high intensity noise may cause
hearing loss.
i) Keep bystanders a safe distance away from work area. Anyone
entering the work area must wear personal protective equip-
ment. Fragments of workpiece or of a broken accessory may fly
away and cause injury beyond immediate area of operation.
j) Hold the power tool by insulated gripping surfaces only when
performing an operation where the cutting accessory may con-
tact hidden wiring or its own cord. Cutting accessory contacting
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 cloth-
ing, 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 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,
backing pad, brush or any other accessory. Pinching or snagging causes
rapid stalling of the rotating accessory which in turn causes the uncon-
trolled power tool to be forced in the direction opposite of the accesso-
ry's rotation at the point of the binding.
For example, if an abrasive wheel is snagged or pinched by the work-
piece, 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, de-
pending 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 precau-
tions 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 kick-
back or torque reaction during start-up. The operator can con-
trol 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 ade-
quately 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. Overstress-
ing 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 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 rea-
son, switch off the power tool and hold the power tool motion-
less 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 cor-
rective 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
paper. Larger sanding paper extending beyond 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 dur-
ing 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 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.
