WARNING!
Risk from using improper workpiece clamping materials or operating the machine at an
inadmissible speed.
Only use the tool clamping devices (e.g. lathe chuck) that were delivered with the
machine or those offered by OPTIMUM as optional equipment.
Only use tool clamping devices in the intended admissible speed range.
3.7
Electrical connection
The machine is installed ready for operation with a 400V three-phase plug. Please verify if the
type of current, voltage and protection fuse correspond to the values specified. A protective
earth ground wire connection must be available. Mains fuse 10A to 16A.
Make sure that the direction of rotation of the drive motor is correct. In the switch position of the
rotary direction switch of counter clockwise rotation (L), the spindle should rotate counter
clockwise. If necessary two phase terminals on three-phase connector or your three-phase
connection must be exchanged.
WARNING!
The three-phase electrical connection may only be performed by an electrician or under
the guidance and supervision of an electrician.

CAUTION!
Arrange the machine's connection cable in such a way that it will not cause a tripping
hazard.
3.8
Warming up the machine
ATTENTION!
If the lathe and in particular the lathe spindle are immediately operated at maximum load
when cold, this may result in damages.
INFORMATION
For a long service life of your lathe, during the first operating hours, we recommend that you do
not exceed a maximum revolution speed of 500 rpm. If the machine is cold, e.g. directly after
having transported the machine, it should be warmed up at a spindle speed of only 500 1/min
for the first 30 minutes.
