WARNING!
Extremely severe injuries.
It is forbidden to make any modifications or alternations to the operation values of the
radial drilling machine! They could endanger the personnel and cause damage to the
radial drilling machine.
1.4 Reasonably foreseeable misuse
Any use other than that specified under "Intended use" or any use beyond that described will be
deemed non-intended use and is not permissible.
Any other use must be discussed with the manufacturer.
It is only allowed to process metal, cold and non-inflammable materials with the radial drilling
machine.
In order to avoid misuse, it is necessary to read and understand the operating instructions
before the first commissioning.
Operators must be qualified.
1.4.1 Avoiding misuse
Use of suitable cutting tools.
Adapting the speed adjustment and feed to the material and workpiece.
Clamp workpieces firmly and free of vibration.
Pull out the suitable length of shift rod. When shift rod comes into contact with something or
when the workpiece or the clamp breaks loose, the machine must shut down.
WARNING!
Risk of injury caused by flying workpieces.
The workpiece is always to be fixed by a machine vice, jaw chuck or by another
appropriate clamping tool such as for the clamping claws.
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.
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 jams, immediately stop the main motor by pressing the emergency stop
switch,
use commercial cooling/lubricating agents for hard materials, e.g. steel and
generally always back the spindle out of the workpiece while it is still turning.

the event of an emergency. Disconnect the machine immediately if there is a malfunction in the
power supply!
Comply with the required inspection intervals in accordance with the factory safety directive,
operating equipment inspection.
The operating company of the machine must ensure that the electrical systems and operating
equipment are inspected with regards to their proper condition, namely,
by a qualified electrician or under the supervision and direction of a qualified electrician,
prior to initial commissioning and after modifications or repairs, prior to recommissioning
and at certain intervals.
The deadlines must be set so that arising, foreseeable defects can be detected in a timely man-
ner.
The relevant electro-technical rules must be followed during the inspection.
The inspection prior to initial commissioning is not required if the operator receives confirma-
tion from the manufacturer or installer that the electrical systems and operating equipment com-
ply with the accident prevention regulations, see conformity declaration.
Permanently installed electrical systems and operating equipment are considered constantly
monitored if they are continually serviced by qualified electricians and inspected by means of
measurements in the scope of operation (e.g. monitoring the insulation resistance).
1.16 Inspection deadlines
Define and document the inspection deadlines for the machine in accordance with § 3 of the
Factory Safety Act and perform an operational risk analysis in accordance with § 6 of the Work
Safety Act. Also use the inspection intervals in the maintenance section as reference values.

2.5 Emissions
Measurement according to operating conditions
The noise development (emission) of the radial drilling machine is 76 dB(A) at a rotary speed of
1385 rpm, measured at a metre's distance from the gearbox at a height of 1.6m when the
machine is idling.
The noise development (emission) of the radial drilling machine is 79 dB(A) at a rotary speed of
2500 rpm , measured at a metre's distance from the gearbox at a height of 1.6m when the
machine is idling.
If the radial drilling machine is installed in an area where various machines are in operation, the
noise exposure (immission) on the operator of the radial 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 engineering 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 precaution 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 of 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 operator of the machine
to more easily evaluate the hazards and risks.
CAUTION!
Depending on the overall noise exposure and the basic threshold values, machine
operators must wear appropriate hearing protection.
We generally recommend the use of noise and ear protection.
