Service Indicator; Information Shown On The Display - Hilti DX 9–ENP Manual De Instrucciones Original

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.
