Tightening the locking arms into rigid material:
Each of the three locking arm screws use an Opti-Torque indicator ring that snaps
and separates from its plastic ring when the screw is tightened to the correct
torque. The indicator ring falls down the screwdriver shaft.
When this occurs , stop
tightening the screw to avoid overtightening the locking arms to the C-ring.
