Adjusting the Torque Wrench

Overview
Adjust the torque wrench prior to tightening the fixation pins. The necessary torque will vary by
patient.
The locking mechanism prevents the user from applying more than the adjusted torque value to
the fixation pins.
Set the torque wrench to the maximum desired torque to be applied before tightening the
fixation pins. 30 Ncm is the maximum allowed setting.
Torque wrench is delivered with a calibration certificate. The calibration is valid for one year
starting with the first use of the device.
Please also consider the instructions and safety information given in the instruction manual of the
torque wrench manufacturer.
If the torque wrench is likely not to be used for a longer period of time, it is advisable to adjust it to
the minimum value for relaxation of interior parts such as the spring. Remember to readjust the
torque setting before treating the next patient.
