Fig. 13
USING THE ACCESSORIES
The accessories provided with the DELTA 2000 SA to assist key-cutting are:
- pins
- bars.
USE OF THE PINS
The pins are placed between the base of the clamp and the back of the key when the key blanks have
fine stems, for the purpose of ensuring that the key protrudes sufficiently to be cut (fig. 14-C).
Keys which have fine thin stems need two pins (fig. 14-B), the second one to provide a secure grip on
the key.
If the key is too thin to be held securely in the jaw, only one pin should be used (fig. 14-A).
ATTENTION: the pins provided have two different diameters: 1,20 mm and 1,70 mm. It is essential to use pins
with the same diameters for locking both the original and the key blank.
