Switching On And Off - ALFRA ROTABEST 100 RL-E Manual De Instrucciones

Switching on and off

 Check connecting line and plug on damages first.
 Push button MAGNET ON, in order to initiate the magnet and the magnetic adhesion is guaranteed.
For better positioning loosen the clamping lever. Now the drill base can be pivoted 30° to the left or to the right,
respectively it can be slid 10 mm forwards or backwards.
 For non-magnetizable materials, please use the ROTABEST Vacubest (Prod.-No. 18150).
 When working on walls and ceilings, secure machine with safety belt.
For these operations we recommend cooling with our spray ALFRA BIO 4000, Prod.- No. 21040.
 Push the button MOTOR ON to start the Motor.
 To switch off the machine proceed in reverse order, first MOTOR OFF, then MAGNET OFF.
MPI-System
 At function „magnet on", 100% of the mangnet 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 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 one gear with 4 mechanical reduction stages and a full-wave electronic.
At first you need to adjust the correct mechanical adjustment. Afterwards you need to adapt the rotation speed with
the help of the electrical rotation speed regulator.
If it's 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's protected against overheating due to high load.
Thermo protection
The thermo protection stops the motor when it's overheated automatically. Afterwards you need to let it run with a
high rotation speed at the idle speed for about two minutes.
