Torque Charts
These charts are meant to be used as guidelines for setting the torque on the BF-Series electric screwdrivers. The drivers have a torque scale on the torque adjustment nut 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 on 30V. Figures below each chart indicate scale setting on the tool. Some drivers have more than one spring. Select the appropriate spring to achieve the desired torque
setting.
Example:
Using the Red spring, when the torque adjustment nut is set to the # 4 position, the CL-4000 will have an approximate tightening torque of 3 lbf.in.
