Press the “SB6” and “SB7” buttons on the operation station with both hands at the same time, the ram will move downward quickly, and the slider will stop at the speed change point.

Change the foot switch “S1” operation, the ram moves down to the lower dead center at the working speed, and automatically returns to the upper dead center after the lower dead center stops for a certain time, and the slider movement stops.

Note:

  • When the ram does not reach the shift point, if one of the two-hand operation buttons (SB6, SB7) is released, the ram will immediately return to the top dead center. In order to restart, the other button must be released, and then press the two buttons at the same time
  • Once the slider has changed speed, release the foot switch “S1” and the ram will stop immediately. Re operating the foot switch “S1” will continue to move the ram downward.
