3 Description
3.1 Use of the product as directed
The tool is intended for use in the construction industry and associated trades for driving fasteners into steel.
The tool is for hand-held use only.
Modification of the tool is not permissible.
The tool may not be used in an explosive or flammable atmosphere unless it has been approved for use under these
conditions.
To avoid the risk of injury use only genuine Hilti fasteners, cartridges, accessories and spare parts or those of
equivalent quality.
Observe the information printed in the operating instructions concerning operation, care and maintenance.
The tool and its ancillary equipment may present hazards when used incorrectly by untrained personnel or when used
not as directed.
The tool may be operated, serviced and repaired only by trained personnel. This personnel must be informed of any
special hazards that may be encountered.
As with all powder-actuated fastening tools, the tool, magazine, cartridges and fasteners form a technical unit. This
means that trouble-free fastening with this system can be assured only if the Hilti 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 features a 5-way safety system for the safety of the user and all bystanders.
3.2 Piston principle with piston brake
The energy from the propellant charge is transferred to a piston, the accelerated mass of which drives the fastener
into the base material. Due to use of this piston principle, the tool is classified as a “low velocity tool”. Approximately
95 % of kinetic energy is taken up by the piston when the tool is fired. As the piston is always stopped by the piston
brake as it reaches the end of its travel, excess energy is absorbed by the tool. Accordingly, when the tool is used
correctly, dangerous through-shots become virtually impossible.
3.3 Drop-firing safety device
The drop-firing safety device is the result of coupling the firing mechanism with the cocking movement. This prevents
the tool from firing when dropped onto a hard surface, no matter at which angle the impact occurs.
3.4 Trigger safety device
The trigger safety device ensures that a fastener cannot be driven simply by pulling the trigger only. The tool must be
pressed against a firm surface before a fastener can be released.
3.5 Contact pressure safety device
The tool can be fired only when pressed fully against a firm surface with a force of at least 50 N.
3.6 Unintentional firing safety device
The tool is also equipped with an unintentional firing safety device. This prevents the tool from firing if the trigger is first
pulled and the tool then pressed against the work surface. The tool can be fired only when it is first pressed correctly
against the work surface and the trigger subsequently pulled.
