Depending on the working method (as described
under Example A), the vernier can be set to 0. For
this purpose, the turning tool must be brought into
contact with the sealing surface of the engine block.
Then, the locking screw of the advancing
mechanism and the worm screw of the vernier must
be
loosened
The vernier can now be set to the mark on the
guide. The micrometer graduation on the vernier
shows the actual depth of the turning tool bit.
Whenever the turning tool is replaced, this 0-setting
must be repeated. Figure 22
