these pages open while you read the operating instruc­tions.
In these operating instructions, the designation “the

2. Description

2.1 Piston principle

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 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 with a fastener
exit velocity in excess of 100 m/sec therefore become
virtually impossible.

2.2 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.

2.3 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.

2.3.1 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.

2.3.2 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.

Location of identification data on the tool

The type designation and serial number are printed on
the type plate on the tool. Make a note of this informa­tion in your operating instructions and always refer to
it when making an enquiry to your Hilti representative
or service department.
