Kickback And Related Warnings - Bosch TG502 Instrucciones De Funcionamiento Y Seguridad

wheel may fly away and cause injury beyond
immediate area of operation.
Hold the power tool by insulated gripping
surfaces only, when performing an opera-
tion 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 could give the operator an electric shock.
Position the cord clear of the spinning ac-
cessory. If you lose control, the cord may be
cut or snagged and your hand or arm may be
pulled into the spinning wheel.
Never lay the power tool down until the ac-
cessory has come to a complete stop. The
spinning wheel may grab the surface and pull
the power tool out of your control.
Do not run the power tool while carrying it
at your side. Accidental contact with the spin-
ning accessory could snag your clothing, pull-
ing the accessory into your body.
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.
Do not operate the power tool near flam-
mable materials. Sparks could ignite these
materials.
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 snag-
ging 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 move-
ment 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 con-
ditions and can be avoided by taking proper
precautions as given below.
Maintain a firm grip on the power tool and
position your body and arm to allow you
to resist kickback forces. Always use auxil-
1600A003P6 08-14.indd 4
iary handle, if provided, for maximum con-
trol over kickback or torque reaction dur-
ing start-up. The operator can control torque
reactions or kickback forces, if proper precau-
tions are taken.
Never place your hand near the rotating
accessory. Accessory may kickback over
your hand.
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.
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 con-
trol or kickback.
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 fre-
quent kickback and loss of control.
Do not "jam" the wheel or apply excessive
pressure. Do not attempt to make an exces-
sive depth of cut. Overstressing the wheel in-
creases the loading and susceptibility to twist-
ing or binding of the wheel in the cut and the
possibility of kickback or wheel breakage.
When wheel is binding or when interrupt-
ing a cut for any reason, 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 wheel
from the cut while the wheel is in motion
otherwise kickback may occur. Investigate
and take corrective action to eliminate the
cause of wheel binding.
Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed
and carefully re-enter the cut. The wheel
may bind, walk up or kickback if the power tool
is restarted in the workpiece.
Support panels or any oversized work-
piece to minimize the risk of wheel pinch-
ing and kickback. 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.
Use extra caution when making a "pocket
cut" into existing walls or other blind ar-
eas. The protruding wheel may cut gas or wa-
ter pipes, electrical wiring or objects that can
cause kickback.
