ATTENTION!
If the drilling-milling machine is not used as intended or if the safety directives or the
operating instructions are ignored the liability of the manufacturer for any damages to
persons or objects resulting hereof is excluded and the claim under guarantee is
becoming null and void!
1.3 Reasonably foreseeable misuses
Any other use as the one determined under the "Intended use" or any use beyond the
described use shall be deemed as not in conformity and is forbidden.
Any other use has to be discussed with the manufacturer.
It is only allowed to process metal, cold and non-inflammable materials with the milling-
machine.
In order to avoid misuses it is necessary to read and understand the operating instructions
before the first commissioning.
The operators must be qualified.
1.3.1 Avoiding misuses
Use of suitable cutting tools.
Adapting the speed adjustment and feed to the material and workpiece.
Clamp workpieces firmly and vibration-free.
For the drilling-milling machine there are conversion kits.
The attachments are provided as a kit to computer-controlled milling (CNC Computerized
numerical control). However, the control of the step motors can also be done manually via a
special controller (control, potentiometer). A step motor control is required in each case.
The drilling-milling machine must only be installed and operated in a dry and well-ventilated
place.
The machine BF46 Vario | BF46TC covered by the standard DIN EN 13128 (milling machines,
including drilling machines). Therein, the manually controlled machines are divided into two
classes with different protection levels, depending on the travel speed of a single power-driven
axis. In addition, the requirements for automatically controlled machines listed (highest level of
protection).
The one who changed the manually controlled BF46 Vario | BF46TC on CNC control is legally
the manufacturer of a new machine due to the significant change in the machine and is there-
fore responsible for compliance with the requirements of the Machinery Directive and the DIN
EN 13128.
The tool follows a path of movement which is normally not predictable by the operator. Because
of the additional hazards caused by flying parts the standard defines protective devices. It does
not matter what speeds are available on the axes.
We expressly point out that the guarantee will expire due to any constructive technical or proce-
dural changes which had not been performed by the company Optimum Maschinen Germany
GmbH.
With the conversion of the machine BF46 Vario | BF46TC an cabinet is required.
A suitable cabinet for these machines you can order:

WARNING!
Risk of injury caused by workpieces flying off.
Clamp the workpiece in the machine vice. Make sure that the workpiece is firmly clamped in the
machine vice resp. that the machine vice is firmly clamped on 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.
It is recommended:
Insert the drill in a way that it is exactly positioned between the three clamping jaws of the
quick action chuck.
Clamp and mills by means of the collet chuck and the corresponding collets.
Clamp end face mills by means of 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
in case of too strong pressure the drill will get worn early or even might break resp. get
jammed in the hole. If the drill gets jammed immediately stop the main motor by pressing
the emergency stop button,
for hard materials, e.g. steel, use commercial cooling / lubricating agents,
generally always drive the turning spindle out of the workpiece.
ATTENTION!
Do not use the quick action drill chuck for milling tools. Never clamp a milling cutter into
the quick action drill chuck. Use a collet chuck and the corresponding collets for the end
mill.
When milling make sure that
the corresponding 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 in a way that the cutting speed remains constant,
for hard materials commercial cooling / lubricating agents are used.

2.10 Emissions
The generation of noise emitted by the drilling-milling machine is less than 80 dB(A).
If the drilling-milling machine is installed in an area where various machines are in operation,
the noise exposure (immission) on the operator of the drilling-milling machine at the working
place may exceed 80dB(A).
INFORMATION
This numerical value was measured on a new machine under proper operating conditions.
Depending on the age respectively on the wear of the machine it is possible that the noise
behaviour of the machine changes.
Furthermore, the factor of the noise emission is also depending on manufacturing influencing
factors, e.g. speed, material and clamping conditions.
INFORMATION
The mentioned numerical value is the emission level and 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 the proximity and the period of time during which the oper-
ator 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 shall allow the operator of the machine to more eas-
ily evaluate the endangering and risks.
CAUTION!
Depending on the overall noise exposure and the basic limit values the machine
operators must wear an appropriate hearing protection.
We generally recommend to use a noise protection and a hearing protection.
