Special Warnings for this Machine
Warning! There is a risk of the machine accidentally restarting after a power failure,
make sure that all of the operation switches are in the off or neutral positions if the
power is interrupted.
Warning! Always wear approved eye protection when operating this machine.
1.2 Proper use
In the event of improper use the machine will
•endanger personnel,
•endanger the machine and other material property of the operator,
•may affect proper operation of the machine

This milling machine is designed and manufactured to be used for milling and drilling
cold metals or other non-flammable materials that do not constitute a health hazard by
using commercial milling and drilling tools.
This machine must only be installed and operated in a dry and well-ventilated place.
If the milling machine is used in any way other than described above, modified without
authorization or operated with different process data, then it is being used improperly.
We do not take any liability for damages caused by improper use. Any such
modifications would also render the guarantee null and void.
It is also part of proper use that:
•the maximum values for the machine are complied with
•the operating manual is observed
•inspection and maintenance instructions are observed
1.3 Possible dangers caused by the milling machine
As the machine operates with
•high revolutions
•rotating parts and tools
•electrical voltage and currents
There is a residual risk with use. We have used construction resources and safety
techniques to minimize the risk to health to personnel resulting from these hazards.
We have used construction resources and safety techniques to minimize the risk to
health to personnel resulting from these hazards.
If the machine is used and maintained by personnel who are not duly qualified, there
may be a risk resulting from incorrect or unsuitable maintenance.
All personnel involved in assembly, commissioning, operation and maintenance must
•be duly qualified,
•follow this operating manual
Disconnect the machine whenever cleaning or maintenance work is being carried
out.
Warning!
This machine may only be used with the safety devices activated.
Disconnect the machine immediately whenever you detect a failure in the safety
devices or when they are not fitted. All additional installations carried out by the
operator must incorporate the prescribed safety devices.

1.4 Qualification of personnel
This manual is addressed to
•operators,
•users,
•maintenance staff
The warning notes therefore refer to both operation and maintenance of the milling
machine.
Always disconnect the machine plug from the electrical power supply. This will
prevent it from being used by unauthorized personnel.
All personnel involved in assembly, commissioning, operation and maintenance must
•be duly qualified,
•follow this operating manual
In the event of improper use
•there may be a risk to personnel,
•there may be a risk to the machine and other material property,
•the proper operation of the machine may be affected
1.5 Safety devices
Use the milling machine only with properly functioning safety devices.
Stop the machine if there is a failure in the safety device or if it is not functioning for
any reason.
If a device has not been activated or has failed, the milling machine must only be
used when
•the cause of failure has been removed
•it has been verified that there is no resulting danger for personnel or objects
Warning!
If you bypass, remove or override a safety device in any way, you are endangering
yourself any other personnel working with the milling machine. The possible
consequences are
•damage as a result of components or parts of components flying off at high speed.
•contact with rotating parts,
•fatal electrocution
The milling machine includes the following safety devices:
•a self-locking emergency stop button
•a protective cover at the drill-mill head
5
Emergency stop button
The emergency stop button switches the machine off.
Open the cover of the emergency stop button in order to
switch the machine on again.
Protective cover
The drill-mill head is fitted with a protective cover.
Warning!
Remove the protective cover after the mains plug of the machine has been pulled.
1.6 Safety check
Check the milling machine regularly
•at the beginning of each shift,
•once a week,
•after every maintenance and repair operation

Emergency Stop
When the Emergency Stop button is activated, the machine
should switch off automatically. A restart will not be possible
until the Emergency Stop button has been unlocked and the
On switch has been activated.
1.7 Individual protection gear
For certain work individual protection gear is required.
Protect your face and eyes. During all work and specifically work during which your
face and eyes are exposed to hazards, a safety helmet with facial protection should
be worn.
Use protective gloves when handling pieces with sharp edges.
Wear safety shoes when you position, dismantle or transport heavy components.
6
Use ear protection if the noise level (inmission) in the workplace exceeds 80 dB (A).
Before starting work, make sure that the prescribed individual protection gear is
available at the workplace.
Caution!
Dirty or contaminated individual protection gear can cause disease. Clean it after
each use and once a week.
1.8 For your own safety during operation
Warning!
Before activating the machine, double check that it will not endanger other people or
cause damage to equipment.
Avoid unsafe working practices:
•The instructions in this manual must be observed during assembly, handling,
maintenance and repair.
•Use protective goggles
•Turn off the machine before measuring the workpiece.
•Do not work on the machine if your concentration is reduced, for example, because
you are taking medication.
•Stay on the machine until all rotating parts have come to a halt.
•Use the prescribed protection gear. Make sure to wear a well-fitting work suit and a
hairnet, if necessary.
•Do not use protective gloves during drilling or milling work.
•Unplug the shockproof plug from the mains before changing the tool.
•Use suitable devices to remove drilling and milling chips.
•Make sure your work does not endanger anyone.
•Clamp the workpiece tightly before activating the machine.
In the description of work on the drilling-milling machine we highlight the dangers
specific to that work.
1.9 Disconnecting the machine and making it safe
Pull the main plug before beginning any maintenance or repair work.
Warning!
Use of unstable lifting equipment and load-suspension devices that break under load
can cause very serious injuries or even death.
Check that the lifting equipment and load-suspension devices are of sufficient load
capacity and in perfect condition.
7
Observe the rules for preventing accidents issued by your association for the
prevention of occupational accidents and safety in the workplace or other inspection
authorities.
Tighten loads properly.
Never walk under suspended loads!

Emissions
The noise level (emission) of the drilling-milling machine ranges below 78 dB(A). If
the drilling-milling machine is installed in an area where various machines are in
operation, the acoustic influence (inmission) on the user of the drilling-milling
machine may exceed 85 dB(A) in the working area.
We recommend the use of soundproofing and ear protection. Remember that the
duration of the noise pollution, the type and characteristics of the work area and
operation of other machines influence the noise level in the working area.

3. Assembly and Connection
The drilling-milling machine comes pre-assembled.
3.1 Extent of supply
When the drilling-milling machine is delivered, check immediately that the machine
has not been damaged during transport and that all components are included. Also
check that no fastening screws have come loose.
Compare the parts supplied with the information on the packaging list.
3.2 Transport
Warning!
Machine parts falling off forklift trucks or other transport vehicles could cause very
serious or even fata injuries. Follow the instructions and information on the transport
case:
•Centers of gravity,
•Suspension points,
•Weights,
•Means of transport to be used,
•Prescribed shipping position.
Use of unstable lifting equipment and load-suspension devices that break under load
can cause very serious injury or even death.
Check that the lifting and load-suspension gear has sufficient load capacity and that
it is in perfect condition.
Observe the rules for preventing accidents.
Holds the load properly.
Never walk under suspended loads.
3.3 Storage
