Technical Description - Hilti DXA40 Bedienungsanleitung

Technical description:

The Hilti DX A40 with an X-A40/HM steel marking head is suitable for the marking of a wide
variety of base materials regardless of their temperature condition.
The tool works on the well-proven piston principle which thus ensures an optimal safety level.
The piston is returned to the starting position and the cartridges are fed to the firing chamber
automatically by gas pressure from the fired cartridge.
The system permits a high quality mark to be comfortably, quickly and economically applied
to a variety of base materials with temperatures up to 800º C. A mark can be made every 5
seconds or roughly every 30 seconds if characters are changed.
The X-A40/HM steel marking head accepts either 7 of the 8 mm type characters or 10 of the
5,6 mm type characters, with heights of 4, 6, 8, 10 or 12 mm.
The tool has not been approved for use in an explosive atmosphere.
Additional equipment is available on request. Please contact your local Hilti sales
representative.
As with all powder-actuated tools, the DX A40, the X-A40/HM steel marking head, the marking
characters and the cartridges form a "technical unit". This means that troublefree marking
with this system can only be assured if the characters and cartridges specially manufactured
for the tool, or products of equivalent quality, are used. The marking and application recom-
mendations given by Hilti are only applicable if this condition is observed.

Contact pressure safety device:
The pressure required to overcome the cocking force and movement prevents a loaded tool
from being fired if it is not pressed against a firm work surface. The tool can only be fired if the
contact pressure safety device is pressed to overcome a movement of 20 mm (1") and a mini-
mum force of 160 N (36 lbf).
