Switching on the device

After inserting the battery, activate and release the trigger once, which is located on the front part
of the handle.
In this condition, the tool is able to operate immediately, i.e. approached to a rivet, it will carry out the
screwing on the nose. After this operation, the tool is ready to pull the rivet and the selected pull.

Adjustment of the setting force

AT THE TIME OF DELIVERY, THE DEVICE IS SET TO THE MINIMUM FORCE. THE
DEVICE NEEDS TO BE SET FOR THE FIRST USE.
• Connect the battery
• Switch on the device
• To adjust the setting force value, press the
RIGHT button (SET) at any time and keep it
pressed for 2 seconds. The digits indicating
the setting value start to blink.
• Press the LEFT (-) and RIGHT (+) keys,
decreasing or increasing the value in 100N
steps, until the desired value is reached.
• Press the CENTER (OK) confirmation button
or wait 5 seconds without pressing any button.
Please note that when changing the force, the battery life also varies depending on the required pull:
a pull with less force will need less current, so the battery life will be longer and vice versa.
