* These parts may be replaced by the user/operator
It is essential that the operating instruc-
tions are read before the tool is operated
for the first time.
Always keep these operating instructions
together with the tool.
Ensure that the operating instructions are
with the tool when it is given to other per-
sons.
1. Safety precautions
1.1 Basic safety instructions
In addition to the safety precautions listed in the indi-
vidual sections of these operating instructions, the
following points must be strictly observed at all times.
1.2 Only use Hilti cartridges or cartridges of equiva-
lent quality
The use of cartridges of inferior quality in Hilti tools may
lead to build-up of unburned powder, which may explo-
de and cause severe injuries to operators and bystan-
ders. At a minimum, cartridges must either:
a) Be confirmed by their supplier to have been suc-
cessfully tested in accordance with EU standard EN
16264
NOTE:
●
All Hilti cartridges for powder-actuated tools have
been tested successfully in accordance with EN 16264.
●
The tests defined in the EN 16264 standard are system
tests carried out by the certification authority using
specific combinations of cartridges and tools.
The tool designation, the name of the certification aut-
hority and the system test number are printed on the
cartridge packaging.
or
b) Carry the CE conformity mark (mandatory in the EU
as of July 2013).
See packaging sample at:
www.hilti.com/dx-cartridges
1.3 Use as intended
The tool is designed for professional use in fastening
applications in construction where specially-designed
nails, threaded studs and composite fasteners are dri-
ven into concrete, steel and sand-lime block mason-
ry.
