ATTENTION!
Insufficient rigidity of the foundation leads to the superposition of vibrations between
the drilling-milling machine and the foundation (natural frequency of components).
Insufficient rigidity of the entire milling machine assembly also rapidly causes the
machine to reach critical speeds, with unpleasant vibrations, leading to bad milling
results.
Position the drilling-milling machine on the intended foundation.
Attach the drilling-milling machine using the provided recesses in the machine base.
WARNING!
The quality of the substructure and the kind of fixture of the machine stand to the
substructure has to assimilate the loads of the drilling-milling machine. The
substructure needs to be even. Please check the horizontal alignment of the
substructure of the drilling-milling machine.
Fix the drilling-milling machine to the substructure at the provided recesses at the stand.
When using an optionally available machine substructure, it also needs to be anchored safely
and firmly. We recommend the use of shear connector cartridges or heavy-duty bolts.

First use
ATTENTION!
Before you begin with the commissioning on the machines check that all screws, fas-
teners and fuses are tight. If necessary they must be tightened.
WARNING!
Risk by using improper workpiece clamping materials or by operating the machine
with inadmissible speed.
Only use the clamping materials (e.g. drill chuck) which had been delivered together
with the machine or as optional equipment offered by OPTIMUM.
Use the working clamping materials only in the provided admissible speed range.
Workpiece clamping materials must only be modified according to the
recommendations of OPTIMUM or of the clamping material manufacturer.
WARNING!
Staff and equipment may be endanged if the drilling-milling machine is first used by
unexpert staff.
We do not take responsibility for damage caused by incorrect commissioning.

3.5.1 Power supply
Connect the electrical feeder.
Check the fuse protection (fuse) of your electrical supply according to the technical speci-
fications for the total connected load of the drilling-milling machine.
3.5.2 Cleaning and lubricating
Remove the anti-corrosive agent to the drilling-milling machine for transport and storage
purposes. We recommend the use of paraffin.
