ATTENTION!
Tighten the fixing screws of the drilling machine only as much that it is safely fixed and
cannot break away or tilt over.
If the fixing screws are too tight in particular in connection with an uneven substructure it may
result in a broken stand of the machine.
3.5
First commissioning
ATTENTION!
Before initially operating the machine, check all screws, fixtures and/or safety devices
and tighten up the screws if necessary!
WARNING!
Risk from using improper workpiece clamping materials or operating the machine at an
inadmissible speed.
Only use the tool holders (e.g. drill chuck) which were delivered with the machine
or
which are offered as optional equipment .
Only use tool holders in the intended admissible speed range.
Tool holders may only be modified in compliance with the recommendation of OPTIMUM
or of the manufacturer of the clamping devices.
WARNING!
There is a danger to persons and equipment, if the first commissioning of the drilling
machine is carried out by inexperienced personnel.
We do not accept any liability for damages caused by incorrectly performed
commissioning.
3.5.1
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 machine.
Mains fuse 10A to 16A
ATTENTION!
For 400V machines: Ensure that all 3 phases (L1, L2, L3) are connected correctly.
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.
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.
If your connector plug is equipped with a phase inverter, this is done by turning it by
180°.
The guarantee will become null and void if the machine is connected incorrectly.
