1.3 Proper use
WARNING!
In the event of improper use of the bench drill
• there may be a risk to personnel,
• there may be a risk to the machine and other items,
correct functioning of the bench drill may be affected.
The bench drill is designed and manufactured to be used in environments where there is no
potential danger of explosion. The bench drill is designed and manufactured to produce holes in
cold metal or other not health hazardous or not burnable material by using a rotating cutting tool
with several chucking grooves.
If the bench drill is used in any way other than prescribed above, modified without authorization
of Optimum Maschinen Germany GmbH, then the bench drill is being used improperly.
We do not take liability for damage caused through improper use.
We would like to accent that any modifications to the construction, or technical or technological
modifications that have not been authorized by Optimum Maschinen Germany GmbH will also
expire the guarantee.
It is also part of proper use that
the maximum values of the bench drill are complied with,
the operating manual is constantly observed,
inspection and maintenance instructions are observed.
 „Technical Data“ on page 14
WARNING!
Very serious injury.
It is forbidden to make any modifications or alternations to the operating values of the
bench drill! They could endanger employees and cause damage to thebench drill.
1.4 Possible dangers caused by the bench drill.
The bench drill is state of the art.
Nevertheless, there is a residual risk as the bench drill operates with
high revolutions,
rotating parts,
electrical voltage and currents.
We have used construction resources and safety techniques to minimize the health risk to per-
sons resulting from these hazards.
If the bench drill is used and maintained by employees who are poorly qualified, then there
might be a risk resulting from incorrect operation and unsuitable maintenance of the bench drill.
INFORMATION
Everyone involved in the assembly, commissioning, operation and maintenance must
be duly qualified,
strictly follow this operating manual.
Due to improper use
there is a risk for the employee,
the machine and further property might be endangered,
