Hilti BX 3-ME Original Operating Instructions page 26

3.3 Safety devices
In magazine mode, the nail detector prevents triggering without a nail loaded, which could damage the
fastening tool.
The contact pressure safety device is intended to prevent the free flighting of nails (i.e. actuation and driving
a nail when the nosepiece is not in contact with the workpiece). In magazine mode, the fastening tool can
be pressed against the surface and triggered only when a nail is loaded in the tool.
To use the tool in single-fastener mode, you have to press the single-fastener mode switch before pressing
the fastening tool against the working surface.
3.4 Features
The fastening tool has an ergonomic, non-slip, vibration-absorbing grip and a support leg. The tool
is protected from overloading by electronic overload protection and from overheating by temperature
monitoring.
3.5 Bluetooth
The product has a Bluetooth interface. Wireless communication via Bluetooth is possible as soon as the
battery has been fitted and the fastening tool switched on at the on/off button.
Data transfer continues for three hours after the tool has switched to standby mode or after the tool has
been switched off at the on/off button.
To deactivate Bluetooth manually, press and hold down the on/off button for at least 5 seconds until the LED
shows blue twice.
When the battery is removed, no further data are transferred.
