Kickback And Related Warnings - Fein KFH17-8 Manual De Instrucciones

This power tool is also suitable for use with AC gener-
ators with sufficient power output that correspond to
the Standard ISO 8528, design type G2. This Standard
is particularly not complied with when the so-called dis-
tortion factor exceeds 10 %. When in doubt, please
refer to the generator instruction/specification guide.
Special safety instructions.
Hold the power tool only by the insulated gripping sur-
faces, as the cutting tool could cut into the machine's
power cord. Contact with a "live" wire will also make
exposed metal parts of the power tool "live" and shock
the operator.
Fasten and secure the workpiece with screw clamps or
other suitable clamps to a stable surface. When hold-
ing the workpiece manually it is unstable and can lead
to loss of control and injury.
Do not use accessories which are not specifically
designed and recommended by the tool manufacturer.
Just because the accessory can be attached to your
power tool, it does not assure safe operation.
Do not use a damaged accessory. Before each use,
check the indexable inserts for chipping and cracks,
wear or heavy use. If the machine or application tool is
dropped, inspect for damage or install an undamaged
application tool.
Wear personal protective equipment. Depending on
application, use face shield, safety goggles or safety
glasses. Where appropriate, wear dust mask, hearing
protectors, gloves and workshop apron capable of stop-
ping small abrasive or workpiece fragments. The eye
protection must be capable of stopping flying debris
generated by various operations. The dust mask or res-
pirator must be capable of filtrating particles generated
by your operation. Prolonged exposure to high inten-
sity noise may cause hearing loss.
Keep bystanders a safe distance away from work area.
Anyone entering the work area must wear personal pro-
tective equipment. Fragments of workpiece or of a bro-
ken accessory may fly away and cause injury beyond
immediate area of operation.
Always hold the power tool firmly when starting it. The
reaction torque of the motor, as it accelerates to full
speed, can cause the power tool to twist.
If possible, use clamps to fasten or affix the workpiece.
Never hold a workpiece in one hand and the power tool
in the other hand while in use. Clamping workpieces
allows you to use both hands for better control the
power tool.
Never lay the power tool down until the accessory has
come to a complete stop. The spinning accessory 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 spinning accessory could
snag your clothing, pulling 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 powdered metal may cause electrical
hazards.
Do not operate the power tool near flammable materi-
als. Sparks could ignite these materials.
Do not use accessories that require liquid coolants.
Using water or other liquid coolants may result in elec-
trocution or shock.
Secure the work piece firmly. A work piece that is
gripped tightly in a clamping device or vice, is more
secure than if held by hand.
Before putting into operation, check the mains connec-
tion and the mains plug for damage.
Recommendation: The tool should always be supplied
with power via a residual current device (RCD) with a
rated current of 30 mA or less.

Kickback and related warnings

Kickback is the sudden reaction to a pinched or snagged
rotating application tool. Pinching or snagging causes
the rotating application tool to rapidly stop. This can
cause a power tool to be forced in the opposite direc-
tion to the rotating application tool at the point of bind-
ing.
For example, if the indexable insert is snagged or
pinched in the workpiece, the edge of the indexable
insert entering into the workpiece can get caught, caus-
ing the indexable insert to break out or cause kickback.
The indexable-insert holder may either jump toward or
away from the operator, depending on the direction of
the indexable-insert holder at the point of binding.
Indexable inserts can also break under these conditions.
Kickback is the result of power tool misuse or incorrect
operating procedures. It can be avoided by taking
proper precautions as described below.
Maintain a firm grip on the power tool and position your
body and arms to allow you to resist kickback forces.
The operator can control torque reactions or kickback
forces, if proper precautions are taken.
Use 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.
Always feed the application tool into the material in the
same direction as the cutting edge is exiting from the
material (which is the same direction as the chips are
thrown). Guiding the power tool in the wrong direction
causes the cutting edge of the application tool to climb
out of the workpiece and pull the tool in the direction
of this feed.
Do not jam or seize the indexable insert or apply exces-
sive pressure. Do not set a larger bevel height than the
maximum allowed. Overstressing the indexable inserts
increases the loading and susceptibility to wedging or
snagging in the cut, and thus increases the possibility of
kickback or indexable insert breakage.
