The control knob must be in the position -1-. The setting is a maximum pressure of 200 bar. In position -2- (700 bar) the nominal load of the spindle is exceeded.

CAUTION:

Risk of destroying components due to the pressure setting being too high.

- Never set the pressure greater that the specified (position 1 = 20 MPa).

CAUTION:

Risk of personal injury and property damage caused by the spindle breaking or the assembly tool deforming. Uncontrolled flying broken pieces possible.

- Wear safety gloves.

- Wear protective headgear with a visor.

- Pay attention when operating the foot pump, to not push the switch button in the lower position.
