For your safety.
Read all safety warnings and all
instructions. Failure to follow the
warnings and instructions may result in electric shock,
fire and/or serious injury.
Save all warnings and instructions for future reference.
Do not use this power tool before you have thor-
oughly read and completely understood this
Instruction Manual and the enclosed “General
Safety Instructions” (document number
3 41 30 054 06 1). The documents mentioned should be
kept for later use and enclosed with the power tool,
should it be passed on or sold.
Please also observe the relevant national industrial safety
regulations.
Intended use of the power tool:
hand-held core drill for drilling in metal and for tapping in
weather-protected environments without water supply
using the application tools and accessories recommended
by FEIN.
Do not use the power tool in a drill stand.
This power tool is also suitable for use with AC genera-
tors with sufficient power output that correspond to the
Standard ISO 8528, design type G2. This Standard is par-
ticularly not complied with when the so-called distortion
factor exceeds 10 %. When in doubt, please refer to the
generator instruction/specification guide.
Special safety instructions.
Use auxiliary handle(s), if supplied with the tool. Loss of
control can cause personal injury.
Hold the power tool by the insulated gripping surfaces,
when performing an operation where the cutting acces-
sory may contact hidden wiring or its own cord. A cutting
accessory contacting a “live” wire may make exposed
metal parts of the power tool “live” and shock the oper-
ator.
Beware of any concealed electric cables, gas or water
conduits; check the working area with a metal detector,
for example, before commencing work.
Avoid contact with the core, which is automatically thrust
out by the centering drill bit after the working procedure.
Contact with the hot or falling down core can lead to
injury.
Secure the workpiece 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 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.
