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. This
prevents the tool from firing when dropped onto a hard surface, no matter at which angle the impact occurs.
Trigger safety device
The 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 device
The contact pressure safety device requires a force of at least 50 N, so a fastener can be driven only when
the tool is pressed fully against a firm surface with this force.
Unintentional firing safety device
The tool is 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.
3.5 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.
Note
Demo mode does not indicate the actual status of the tool.
The number of fasteners driven is also recorded while in demo mode, so the total counted is always
the actual value.

Information shown in the middle of the display
Display
Explanation
The tool temperature is shown in the middle of the display.
In this case the tool temperature is within the normal range.
The temperature of the tool is extremely high. A warning symbol
indicates that use of the tool should not be interrupted when the
tool reaches this temperature as cartridges may ignite prematurely
and the plastic nail strip may melt. We therefore recommend that the
tool continues to be used, but at a lower fastening rate, so that the
temperature of the tool can return to normal.
Important:
The cartridge strip and the fastener strip must be removed from
the tool immediately if use of the tool is interrupted while a warning
symbol is displayed.
Information shown in the lower part of the display

Explanation
At the lower left edge, a bar showing 1 to 7 segments indicates the
interval until the tool needs to be cleaned again.
In this case, cleaning will not be necessary for some time.
The 7 segments shown indicate that cleaning will be necessary
shortly.

5 Operation
5.1 Preparations at the workplace
5.1.1 Establishing the position of the fasteners
To avoid incorrectly driven fasteners, proceed as follows:
▶ Each time you lay a metal sheet in position on the steel beams, use a water-resistant pen to mark the
area in which fasteners can be driven.
Note
Do this each time, for each individual metal sheet. It is not sufficient to simply mark the ends of
the beam and then draw a straight line between these points as the supporting beams may be
distorted, i.e. curved.
5.1.2 Checking that the tool is ready for use
Note
This check should always be carried out immediately before use of the fastening tool and after
reassembling the tool after cleaning or after a routine check of the condition of the piston and piston
stopper.
1. Check the fastening tool for visible signs of damage,
especially to the components shown in the illustration.
Result
Visible signs of damage are found.
▶ Have the tool repaired by Hilti Service.
