The drop-firing safety device is the result of cou-
pling the firing mechanism with the cocking move-
ment. This is designed to help prevent the Hilti DX tool
from firing when it is dropped onto a hard surface, no
matter at which angle the impact occurs.
The trigger safety device ensures that the cartridge
cannot be fired simply by pulling the trigger only. The
tool can be fired only when fully depressed.
The contact pressure safety device requires the tool
to be fully depressed with a significant force. The tool
can be fired only when pressed fully in this way.
In addition, all Hilti DX tools are equipped with an unin-
tentional firing safety device
. This prevents the tool
from firing if the trigger is pulled and the tool then pressed
against the work surface. The tool can be fired only when
it is first pressed
쩸
correctly and
쩹
the trigger then
pulled.
