    • Replace the safety cover (2) and fasten screws (3) (Fig. 2). • Place the ST730T on a bench so that its front edge is flush with the edge of the bench. This way the stripping debris can fall into a waste basket.

  • Page 12: Setting The Mains Voltage

    +41 32 373 70 Setting the Mains Voltage Turn OFF the ST730T with the main switch (A) and disconnect the power cord. • Use a screwdriver to pull out the fuse holder (8). • Remove the voltage selector (7) and place it in the de- sired position of the fuse holder (8).

  • Page 13: Operation

    Operation Testing of Functionality Provided with the ST730T are two cable samples with different insulation thicknesses. One end of each cable was stripped with the machine for testing at the factory. The respective stripping values are stored in programs Cable 1, Cable 2, Cable 3 (for the thinner cable) and Cable 4 and Cable 5 (for the thicker cable).
