Main Spindle Driving
Before starting the machine, a check on the tension of the belt should be made. The belt should be depress
about 10mm under normal finger pressure. The tension of the belts can be adjusted by lever 8.
The main spindle running; stop, forward and reverse function can be realized by the shift switch 3. If you need to
change the direction of rotation, turn the shift switch to the middle position, wait a moment, then switch to the
required direction.
