Clamp the workpiece in the machine vice. Make sure that the workpiece is firmly clamped in the
machine vice and that the machine vice is firmly clamped onto the machine table.
Use cooling and lubricating agents to increase the durability of the tool and to improve the
surface quality.
Clamp the cutting tools and workpieces on clean clamping surfaces.
Sufficiently lubricate the machine.
Correctly adjust the bearing clearance and the guidings.
Recommendations:
Insert the drill in a way that it is exactly positioned between the three clamping jaws of the
quick action chuck.
When drilling make sure that
the suitable speed is set depending on the diameter of the drill,
the pressure must only be such that the drill can cut without load,
if there is too much pressure, the drill will wear quickly and may even break or jam in the
borehole. If the drill gets jammed immediately stop the main motor by pressing the emer-
gency stop button,
for hard materials, e.g. steel, use commercial cooling / lubricating agents,
generally always back the spindle out of the workpiece while it is still turning.
1.4 Possible dangers caused by the drilling machine
The drilling machine has undergone a safety inspection (analysis of danger with assessment of
risks). It has been designed and built on the basis of this analysis using the latest technological
advances.
Nevertheless, there is a residual risk as the drilling machine operates with
at high speeds,
rotating parts,
electrical voltage and currents.
We have used construction resources and safety techniques to minimize the health risk to per-
sonnel resulting from these hazards.
If the drilling machine is used and maintained by personnel who are not duly qualified, there
may be a risk resulting from incorrect or unsuitable maintenance of the drilling machine.
INFORMATION
Everyone involved in the assembly, commissioning, operation and maintenance must
be duly qualified,

2.18 Emissions
The generation of noise emitted by the drilling machine is 73 dB(A) at idle. If the drilling
machine is installed in an area where various machines are in operation, the noise exposure
(immission) on the operator of the drilling machine at the working place may exceed 80 dB(A).
INFORMATION
This numerical value was measured on a new machine under the operating conditions specified
by the manufacturer. The noise behaviour of the machine might change depending on the age
and wear of the machine. Furthermore, the noise emission also depends on production engi-
neering factors, e.g. speed, material and clamping conditions.
INFORMATION
The specified numerical value represents the emission level and does not necessarily a safe
working level. Though there is a dependency between the degree of the noise emission and the
degree of the noise disturbance it is not possible to use it reliably to determine if further precau-
tion measures are required or not.
The following factors influence the actual degree of the noise exposure of the operator:
Characteristics of the working area, e.g. size or damping behaviour,
other noise sources, e.g. the number of machines,
other processes taking place in proximity and the period of time, during which the operator
is exposed to the noise.
Furthermore, it is possible that the admissible exposure level might be different from country to
country due to national regulations.
This information about the noise emission should, however, allow the machine operator to eval-
uate the hazards and risks more easily.
CAUTION!
Depending on the total noise exposure and the basic threshold values, machine
operators must wear appropriate hearing protection.
We generally recommend the use of noise protection and hearing protection.
