Fastening Technique
Direct fastening with powder actuated tools has been in use with
excellent results for many years. Many users value the dependability
and speed with which high-quality fastenings can be produced.
Of critical importance for troublefree working with direct fastening
systems is the correct choice of components: powder actuated tool,
fastener and cartridge.
BiERBACH ® powder actuated tools satisfy all standard safety
requirements. They have been tested and approved by the German
Institute of Physics and Metrology (PTB). This is documented on the
tools by a mark of approval. The following features
underline the high safety standards of BiERBACH ®
powder actuated tools.
● Piston Principle
In BiERBACH ® powder actuated tools the power of the cartridge
does not act directly on the fastener, but on a piston. The energy
released on ignition of the cartridge is first transferred to the
piston. The piston hits the fastener and drives it into the work
surface. The path of the piston in the tool is limited. If not all the
cartridge energy is used up for when driving a fastener into the
work surface, the piston in the tool is intercepted and the excess
energy is dissipated. Penetration through the work surface and
ricochets of the tool are therefore largely prevented.
● Trigger Protection
The trigger protection of BiERBACH ® powder actuated tools
prevents unintentional firing of the tool. Ignition is only possible if
the tool is pressed against a work surface with a force of at least
50 N and the trigger is pressed.

Technical Information
● Fall Protection
The sturdy construction of the tool guarantees it will not ignite
even if it is dropped on to a hard surface from a height of
3 metres.
● Noise Insulation
The noise of the cartridge on ignition is reduced substantially by
the special construction of BiERBACH ® powder actuated tools.
Users and the environment are protected.
● Repeat inspection
According to § 15 (1) of the German Third Weapons Order,
powder actuated tools sold and used in Germany must be
returned to the manufacturer for repeat inspection every two
years. The date of the last inspection is shown on a plaque on
the tool.
The number in the middle of the plaque indicates the year and
the triangle on the setting-direction side the quarter of the last
inspection.
