First commissioning
ATTENTION!
Before commissioning the machine check all screws, fixtures resp. safety devices and
tighten up the screws if necessary!
WARNING!
When first commissioning the lathe by inexperienced staff you endanger people and the
machine.
We do not take any liability for damages caused by incorrectly performed commission-
ing.
3.6.1 Warming up the machine
ATTENTION!
If the lathe and in particular the lathe spindle is immediately operated at maximum load
when it is cold it may result in damages.
If the machine is cold such as e.g. directly after having transportation, the machine should be
warmed up for the first 30 minutes at a spindle speed of only 500 1/min.
3.6.2 Cleaning and lubricating
Remove the anti-corrosive agents on the lathe which had been applied for transportation
and storage. Therefore, we recommend you to use paraffin.
Do not use any solvents, cellulose thinner or any other cleaning agents which might affect
the coating of the lathe when cleaning the lathe. Observe the indications and notes of the
manufacturer for cleaning agents.
Oil all blank machine parts using an acid-free lubricating oil.
Grease the lathe according to the lubrication chart.

3.6.4 Functional test
Check if all spindles are running smoothly.
Check the state of the lathe chuck and the turning jaws.
3.6.5 Electrical connection
Connect the electrical supply cable.
Check the fusing (fuse) of your electrical supply according to the technical instructions
regarding the total connected power of the lathe.
ATTENTION!
For 400V machines: Imperatively make sure that all 3 phases ( L1, L2, L3) are correctly
connected.
Most motor defects result of wrong connections. For instance if a motor phase is not
correctly clamped or connected to the neutral conductor (N)..
Effects may be as follows:
The motor is getting hot very rapidly.
Increased motor noises.
The motor has no power.
