Version 1.1.1 - 2021-1-25 9Translation of original instruction
MB4 EN
MB4_GB_1.fm
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.
Risk of fire and explosion due to the use of flammable materials or cooling lubricants.
Before processing inflammable materials (e.g. aluminium, magnesium) or using inflamma-
ble auxiliary materials (e.g. spirit), you need to take additional preventive measures in order
to avoid health risks.
When processing plastics, the machine operator must ensure that static electricity gener-
ated during the machining process can be discharged easily.
When processing carbons, graphite and carbon-fibre-reinforced carbons, the machine is no
longer being used as intended. This causes the warranty to be null and void. When pro-
cessing carbons, graphite and carbon-fibre-reinforced carbons and similar materials, the
machine can be damaged extremely quickly, even if the dusts generated are completely
sucked out during the work process.
ATTENTION!
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.
WARNING!
Risk of injury caused by flying workpieces.
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.
Set the bearing clearance and guides correctly.
Recommendations:
Insert the drill in a way that it is exactly positioned between the three clamping jaws of the
quick action chuck.
Clamp end mills (or shank cutters) in a collet chuck using the corresponding collets.
Clamp end face mills using shell end mill arbors.
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,
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.
ATTENTION!
Do not use the quick action drill chuck for milling tools. Never clamp a milling cutter into a quick
action drill chuck. Use a collet chuck and appropriate collets for end mills.
When milling, ensure that
the right cutting speed is selected;
for workpieces with normal strength values, e.g. steel, 18-22 m/min,
for workpieces with high strength values, 10-14 m/min,
the pressure is selected so that the cutting speed remains constant,

Version 1.1.1 - 2021-1-2510 Translation of original instruction

Comply with the required inspection intervals in accordance with the factory safety directive,
operating equipment inspection.
The operator 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).
1.17 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.

Emissions
The generation of noise emitted by the drilling-milling machine is 76 dB(A) at 80% of max.
speed without tool.
If the drilling- milling 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 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 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 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.
