Not my own translation. Italics are mine:

TSA-371 Instructions

The preset number combination is 000

To set your personal code, you will lead the following steps:

1: Set the number plate (b) to the preset number combination 000.

Press down the button (a) until you hear a 'click'.

2: Ask a combination in which you spin the number wheels (b), for example 888

3: Press the button (c) in direction of arrow and if you hear a 'click', the button is returned to its starting position. Now you have set your personal combination.

4: Please repeat steps 1-4 if you want to change your combination.

You can do this in steps 1[use ?] Your personal combination of numbers, instead of the Pre-set sequence of numbers 000.
