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 mill drill is 80 dB(A).
If the mill drill is installed in an area where various machines are in operation, the noise expo-
sure (immission) on the operator of the mill drill 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.

3.4 Installation and assembly
3.4.1 Requirements regarding the installation site
Organize the working area around the drilling machine according to the local safety regulations.
INFORMATION
In order to attain good functionality and a high processing accuracy as well as a long durability
of the machine the installation site should fulfil certain criteria.
Please observe the following points:
The device must only be installed and operated in a dry and well-ventilated place.
Avoid places nearby machines generating chips or dust.
The installation site must be free from vibrations also at a distance of presses, planing
machines, etc.
The substructure must be suitable for the mill drill. Also make sure that the floor has suffi-
cient load bearing capacity and is level.
The substructure must be prepared in a way that possibly used coolant cannot penetrate
into the floor.
Any parts sticking out such as stops, handles, etc. have to be secured by measures taken
by the customer if necessary in order to avoid endangerment of persons.
Fragile goods
(Goods require careful handling)
Protect against moisture and humid environment
