BLG-Series Operating Instructions
Torque Reference Charts
These charts are meant to be used as guidelines for setting the torque on the BLG-Series electric screwdrivers. The drivers
have a torque adjustment scale showing reference numbers. These numbers determine the approximate torque setting. Refer
to the charts to determine the reference number setting for your torque requirement.
How to Read the Torque Charts
Torque ranges (lbf.in) approximate tightening torque, operated with no load at maximum speed. Verify torque setting with a
torque testing system.
