Intended use
The product described is a fastening tool designed to drive special fasteners for fastening trapezoidal profile metal sheets to steel beams.
Possible misuse
The fastening tool may not be operated in atmospheres or environments where there is a risk of fire or explosion.The fastening tool may not be used with cartridges and fasteners other than those approved for use with this fastening tool.
The fasteners may not be driven into materials other than structural steel and, in particular, not into hardened steel, brittle steel, cast iron and spring steel.
Safety devices
The fastening tool features a 5-way safety system for the safety of the operator and any bystanders.Piston principleThe energy from the propellant charge is transferred to a piston, the accelerated mass of which drives the nail into the base material.
Through use of the piston principle, the tool is classed 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 tool 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 (i.e. with a nail muzzle velocity of over 100 m/s) are virtually impossible.
Drop-firing safety deviceThe drop-firing safety device is the result of coupling the firing mechanism with the cocking movement.
Trigger safety deviceThe trigger safety device prevents the tool firing when only the trigger is pulled. The tool must be pressed against a firm surface before a fastener can be driven.
Contact pressure safety deviceThe contact pressure safety device requires application by the operator of a contact pressure of at least 250 N, so a nail can be driven only when the tool is pressed fully against a firm surface with this or a higher force.
Unintentional firing safety deviceThe tool is equipped with an unintentional firing safety device. It prevents the tool from firing if the triggers are first pulled and the tool then pressed against the work surface. The tool can be fired only when it is first pressed fully against a firm surface and the triggers subsequently pulled.
Minimum distances and edge distances
You must always observe certain minimum distances and spacing when driving fasteners. They can differ, depending on the product.Service indicator
The service indicator display incorporated in the grip consists of the display plus the Bluetooth and reset buttons.The display indicates the temperature of the fastening tool with a view to allowing the operator to avoid overheating problems by adjusting the speed of use of the tool.
The service indicator display counts the number of fasteners driven and when the preconfigured limit is reached it indicates that cleaning or maintenance of the tool is due.
Using Bluetooth, the data shown in the service indicator display, including the number of fasteners driven and other information (e.g. the serial number of the tool, the number of fasteners driven since the last tool service, etc.), can be read by the Hilti Connect smartphone app.
After cleaning, the number of fasteners driven before cleaning is again due can be reset by pressing the reset button.
The service indicator and the built-in counter for the number of nails that can be driven before the next service is due are reset by Hilti Service when the tool is serviced.
The smartphone app can be used to activate demo mode in which the various messages indicated by the service interface over a period of 48 fasteners driven, up to and including the need for maintenance, are presented.
The smartphone app can also be used to deactivate demo mode. Demo mode is automatically deactivated after a period of 15 minutes.
