The calibration gauge is located at the bottom of the CREA-SWISS. You can calibrate the gauge yourself with the help of the operating instructions.
It is possible that weld spatters have got caught in the toothed rack. Move the gauge fully apart and clean the toothed rack. If this does not help, set the sliding clutch a little tighter. The procedure has been described in the operating instructions.
Often enough there is one man missing to turn the element, especially in smaller companies. The gauge can be set so fast that a maximum of time saving is achieved especially in case of individual units.
This is easily possible by means of a clamping device made by Bessay Company (order No. VAD).
