Thank you for your purchasing HIOS “JUKUREN” BLG-BC2 Screwdriver.
■Pulse System
The pulse system is a mechanism using an electric signal (pulse) that occurs during motor revolutions.
By installing several fasteners into the assembly the driver learns the numbers of motor revolutions
required to correctly tighten the fasteners to the desired torque. The driver then establishes the minimum to
maximum revolutions for process acceptance and displays the result of screw tightening with the LED green
and red lights on the unit.
