OPERATION
1. Set the Torque Wrench to the desired torque by pulling the
lever at the end,

lever when desired torque level is reached on the Graduation
Scale present on the handle.
3. Mount the Socket on the Square Drive and Install the Torque
Wrench on the Fastener and apply force on the Middle of
the Handle for Accurate Torque Measurement.
4. Stop applying force when “Click Sound” is heard as the
desired Torque level is reached.
5. After useage, unmount the Torque Wrench from the
Fastener, remove the socket, release the lever and rotate it
anti-clockwise and bring it to the default position and store
it in the box provided.
SAFETY INSTRUCTIONS

and Torque Wrench.
• Over Tightening of Fasteners may result in Breakage.
• Always use Eye Protection while using hand tools.
• Handle is not Insulated, do not use on live electrical or high
voltage circuits.
• While setting the torque, do not rotate the lever of the
