Check if all spindles are running smoothly.
3.7.1 Electrical connection
CAUTION!
Install the connection cable of the machine in such a way that people will not stumble
over it.
Please verify if the type of current, voltage and protection fuse correspond to the values speci-
fied. A protective earth ground wire connection must be available. Mains fuse 10A to 16A
ATTENTION!
Ensure that all 3 phases (L1, L2, L3) and the ground wire are connected correctly. The
neutral conductor (N) of its power supply is not connected.
ATTENTION!
Make sure that the direction of rotation of the drive motor is correct. The switch position
of the rotation selector switch for right-handed rotation (R) has to turn the drill spindle
clockwise. If necessary, exchange two phase connections. The guarantee will become
null and void if the machine is connected incorrectly.
3.8
First commissioning
The machine may only be commissioned after proper installation.
ATTENTION!
Before commissioning the machine, all bolts, fastenings and protections must be
checked and retightened as necessary!
WARNING!
The use of improper tool holders or their operation at inadmissible speeds constitutes a
hazard.
Only use the tool holders (e.g. drill chuck) which were delivered with the machine or
which are offered as optional equipment by OPTIMUM.
Only use tool holders in the intended admissible speed range.
Tool holders may only be modified in compliance with the recommendation of OPTI-
MUM or of the manufacturer of the clamping devices.
WARNING!
There is a danger to persons and equipment, if the first commissioning of the radial
drilling machine is carried out by inexperienced personnel.
We do not assume any liability for damages caused by incorrectly performed
commissioning.

3.8.1 Warming up the machine
ATTENTION!
If the radial drilling machine and in particular the drilling spindle is immediately operated
at maximum load when it is cold it may result in damages.
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.
