3 Description
3.1 Use of the product as directed
en
The Hilti DX 351‑CT is a powder-actuated tool designed
for driving nails into concrete, steel and other materials suitable for DX fastening (see Fastening Technology
Manual).
The tool utilizes a captive piston to provide optimum
functional reliability and working safety. The tool features
automatic piston return and cartridge transport powered
by gas pressure resulting from operation of the tool. Nails
of up to 37 mm in length can thus be driven very quickly
and efficiently.
As with all powder-actuated fastening tools, the tool, the
fastener guide, the grip, the fasteners and the cartridges
form a single “technical unit”. This means that troublefree fastening with this system can be assured only if
fasteners and cartridges specially manufactured for it, or
products of equivalent quality, are used. The fastening
and application recommendations given by Hilti apply
only when these conditions are observed.
The tool is designed for professional use and may be
operated, serviced and maintained only by trained, authorized personnel. This personnel must be informed of
any special hazards that may be encountered. The tool
and its ancillary equipment may present hazards when
used incorrectly by untrained personnel or when used
not as directed.
To avoid the risk of injury use only genuine Hilti fasteners, cartridges, accessories and spare parts or those of
equivalent quality.
Modification of the tool is not permissible.
3.2 Through-shot and ricochet safety device
As a result of the piston principle, the DX 351-CT is
classified as a low-velocity tool. Most excess driving
energy is dissipated inside the tool.
3.3 Drop-firing safety device
The drop-firing safety device is the result of coupling the
firing mechanism with the cocking movement. This helps
prevent the tool firing when dropped onto a hard surface,
no matter at which angle the impact occurs.
3.4 Trigger safety device
The trigger safety device prevents the tool firing when
only the trigger is pulled. The tool can be fired only when
it is pushed fully against the working surface, pointing
upwards, and the grip pressed.
3.5 Contact pressure safety device
The contact pressure safety device prevents the tool firing
unless it is firmly pressed against a surface. The tool can
be fired only when pressed fully against a surface with a
force of at least 140 N.
3.6 Gravitation safety device
The gravitation safety device prevents the tool firing when
in a horizontal position or when pointing toward the floor.
The tool can be fired only when it is pointing upwards.
