ALFRA ROTABEST 130 Mode D'emploi page 14

Start-up
You receive a completely assembled magnetic core drilling machine and detailed operation manual. Please check
the condition of the goods on receipt for any transport damage, and make sure the delivery is complete. Otherwise
contact the manufacturer immediately.
Always read the operation manual before using the device for the first time!
5. Check connecting line and plug on damages first.
6. Push the button MAGNET ON, so that the magnet adheres and the adhesion of the drill stand is ensured.
 For non-magnetizable materials please use the ROTABEST Vacubest (Prod.-No. 18150).
7. When working on walls and ceilings, secure machine with safety belt.
For these operations we recommend the cooling with a spray e.g. ALFRA BIO 4000, Prod.- No. 21040.
8. Push the button MOTOR ON to start the motor.
2. To switch off the machine proceed in reverse order. First push the button MOTOR OFF, then push the button
MAGNET OFF.
MPI-System
 At function „magnet on", 100% of the magnet power is available right from the beginning.
 Simultaneously a timing relay will be activated which is preset to 60 seconds. If the motor will not
be switched on after "magnet on", the LED of the magnet switch on the key pad is flashing and a buzzer sounds
at the same time. This time-controlled alarm will be also activated after drilling is done and the motor is switched
off but the magnet is still on.
 A functional check of the LED and of the buzzer is carried out if the machine will be connected to
the mains with the electric cable (short flashing of the LED and short buzzing). With it it's possible to test the
model in use respectively the control in use fast and easily on site.
 The new PCBs are 100% compatible with machines of older type series, i.e. in case of repair they can be
replaced respectively exchanged without problems.
Adjustment of the rotation speed
The machine has a gear unit with 4 mechanical reduction stages and a full-wave electronic.
 First you have to adjust the correct mechanical adjustment. Then you have to adapt the rotation speed with the
electrical rotation speed regulator.
 If possible always choose the adjustment with low gear shifting and high engine speed. Then the motor is set at
a high torque and therefore it is protected against overheating due to high load.
Thermo protection
The thermo protection stops the motor automatically when it is overheated. Afterwards let it idle with a high rotation
speed for about two minutes.
