3.2 Intended use
The product described is a fastening tool designed to drive special fasteners for fastening trapezoidal profile
metal sheets to steel beams.
3.3 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.
3.4 Safety devices
The fastening tool features a 5-way safety system for the safety of the operator and any bystanders.
Piston principle
The 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 device
The drop-firing safety device is the result of coupling the firing mechanism with the cocking movement.
