After inserting the desired marking charac-
ters, they must be secured by turning the
locking lever.

The tool and head are now in the ready to
operate position.

b) When using 4 or 6 marking characters:
Insert the marking characters with a "–" at
one end or the other of the desired character
string. In this way, an even impact is achiev-
ed.
Caution:
– Use only original space characters as
blank space. In emergency, a normal
character can be ground off and used.
– Do not insert marking characters
upside-down. This results in shorter
life length of the impact extractor and
reduces the marking quality.
