tions can be found on the fold-out cover pages. Keep
these pages open while you read the operating instruc-

In these operating instructions, the designation "the
tool" always refers to the DX 462CM / DX 462HM pow-
der-actuated tool.
Location of identification data on the tool
The type designation and the serial number are printed
on the type plate on the tool. Make a note of this infor-

3. Description

The Hilti DX 462HM and DX 462CM are suitable for
the marking of a wide variety of base materials.
The tool works on the well-proven piston principle
and is therefore not related to high-velocity tools. The
piston principle provides an optimum of working and
fastening safety. The tool works with cartridges of
6.8/11 caliber.
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 com-
fortably, quickly and economically applied to a variety
Symbols of base materials with temperatures up to 50° C for
the DX 462CM and with temperatures up to 800° C
with DX 462HM. A mark can be made every 5 seconds
or roughly every 30 seconds if characters are chan -
ged.

tion instructions
The X-462CM polyurethane and the X-462HM steel
before use
marking heads accept either 7 of the 8 mm type char-
acters or 10 of the 5,6 mm type characters, with
heights of 6, 10 or 12 mm.
As with all powder-actuated tools, the DX 462HM and
the DX 462CM, the X-462HM and X-462CM marking
heads, the marking characters and the cartridges

form a "technical unit". This means that troublefree
protection
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 recommendations given
by Hilti are only applicable if this condition is
observed.
The tool features 5-way safety – for the safety of the
operator and bystanders.
The piston principle
1
The energy from the propellant charge is transferred to
a piston, the accelerated mass of which drives the fas-
tener into the base material. As approximately 95 % of
the kinetic energy is absorbed by the piston, the fastener
is driven into the base material at much reduced veloc-
ity (less than 100 m/sec.) in a controlled manner. The
driving process ends when the piston reaches the end
of its travel. This makes dangerous through-shots vir-
tually impossible when the tool is used correctly.
The drop-firing safety device
the firing mechanism with the cocking movement. This
prevents the Hilti DX tool from firing when it is dropped
is the result of coupling
