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,

For hard materials, e.g. steel, it is necessary to use commercial cooling/lubricating
agents.Basically, always pull out the drill with rotating spindle from the workpiece.
1.5 Possible dangers posed by the geared drill
The geared drill was built using state-of-the-art technology.
Nevertheless, there is a residual risk as the geared drill operates with

high speeds,

rotating parts,

electrical voltage and currents.
We have used design and safety engineering to minimize the health risk to personnel resulting
from these hazards.
If the geared drill is used and maintained by personnel who are not duly qualified, there may be
a risk resulting from incorrect or unsuitable maintenance of the geared drill.
INFORMATION
Everyone involved in the assembly, commissioning, operation and maintenance must

be duly qualified,

and strictly follow these operating instructions.
In the event of improper use

there may be a risk to personnel,

there may be a risk to the machine and other material values,

the correct function of the geared drill may be affected.
