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.
Hold the power tool firmly. High reaction torque can
briefly occur.
Do not machine any material containing asbestos. Asbes-
tos is cancerogenic.
Do not direct the power tool against yourself, other per-
sons or animals. Danger of injury from sharp or hot
application tools.
Do not rivet or screw any name-plates or signs onto the
power tool. If the insulation is damaged, protection
against an electric shock will be ineffective. Adhesive
labels are recommended.
Do not use accessories which are not specifically
designed and recommended by the power tool manufac-
turer. Safe operation is not ensured merely because an
accessory fits your power tool.
Clean the ventilation openings on the power tool at regu-
lar intervals using non-metal tools. The blower of the
motor draws dust into the housing. An excessive accu-
mulation of metallic dust can cause an electrical hazard.
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.
Hand/arm vibrations
The vibration emission level given in this information
sheet has been measured in accordance with a standard-
ised test given in EN 60745 and may be used to compare
one tool with another. It may be used for a preliminary
assessment of exposure.
The declared vibration emission level represents the
main applications of the tool. However, if the tool is used
for different applications, with different accessories or
poorly maintained, the vibration emission may differ.
This may significantly increase the exposure level over
the total working period.
An estimation of the level of exposure to vibration
should also take into account the times when the tool is
switched off or when it is running but not actually doing
the job. This may significantly reduce the exposure level
over the total working period.
Identify additional safety measures to protect the opera-
tor from the effects of vibration such as: maintain the tool
and the accessories, keep the hands warm, organisation
of work patterns.
Handling hazardous dusts
For work procedures with this power tool where mate-
rial is removed, dusts develop that can be hazardous to
one's health.
Contact with or inhaling some dust types, e. g. asbestos
and asbestos-containing materials, lead-containing coat-
ings, metal, some wood types, minerals, silicate particles
from materials containing stone, paint solvents, wood
preservatives, antifouling paints for vessels, can trigger
allergic reactions to the operator or bystanders and/or
lead to respiratory infections, cancer, birth defects or
other reproductive harm. The risk from inhaling dusts
depends on the exposition. Use dust extraction matched
appropriately for the developing dust, as well as personal
protective equipment and provide for good ventilation of
the workplace. Leave the processing of asbestos-contain-
ing materials to specialists.
Wood and light-metal dust, hot mixtures of grinding dust
and chemical materials can self-ignite under unfavourable
conditions or cause an explosion. Avoid sparking in the
direction of the dust collector as well as overheating of
the power tool and the materials being sanded, empty the
dust collector/container in time, observe the material
manufacturer's working instructions, as well as the rele-
vant regulations in your country for the materials being
worked.
Operating Instructions.
Change the gear setting or the rotation direction only
after the motor has come to a complete stop.
When the power supply is disconnected while the motor
is running or when the switched-on power tool is
plugged in, the motor will not restart.
Insert the pilot bit with a turning motion into the tool
holder until it springs back.
Carry out core-drilling processes without interruption, if
possible. To complete a started and interrupted drilling
run, repeat the center-drilling process.
For stationary use in a drill stand, remove the switched
off power tool from the drill stand every 50 operating
hours while at normal running temperature. Then, turn
the machine around by 180° to achieve uniform lubrica-
tion.
Replace dull pilot bits; they may not be reground.
Remove the chips and the drilled core after each drilling
process.
Chips are sharp and hot!
CAUTION
When changing a drill bit, pay attention not to damage
the cutting edges.
When core drilling layered material, remove the core and
the chippings after drilling each layer.
KBH25-2U: Apply core drilling only in gear setting 2.
Repair and customer service.
When working metal under extreme operat-
ing conditions, it is possible for conductive
dust to settle in the interior of the power tool.
The total insulation of the power tool can be impaired.
Blow out the interior of the power tool via the ventila-
tion slots frequently with dry and oil-free compressed air,
and connect a residual current device (RCD) on the line
side.
If the supply cord of this power tool is damaged, it must
be replaced by a specially prepared cord available through
the FEIN customer service centre.
