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 has to be discussed with the manufacturer.
It is only allowed to process metal, cold and non-inflammable materials with the geared drill.
In order to avoid misuse, it is necessary to read and understand the operating instructions
before first commissioning.
Operators must be qualified.
1.4.1 Avoiding misuse

Use of suitable cutting tools.

Adapting the speed setting and feed to the material and workpiece.

Clamp workpieces firmly and free of vibration.
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.
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
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.
INFORMATION
The drilling machines with frequency converter for regulating the speed is built according to the
standard EN 61800-3 class C.
WARNING!
The machine is not intended for use in residential buildings, in which the power supply
is provided via a public low voltage supply system. In these areas, it may be difficult to
guarantee electromagnetic compatibility due to conducted and emitted interference.
