Setting auto reverse mode
Auto reverse mode means a motion to switch the electric screwdriver rotation direction automatically to the reverse.
This mode is used when tightening a screw temporarily, intentionally loosening a screw (screws for terminal blocks,
etc.) or checking a screw hole.
CAUTION

When the setting is “Reverse after the lower limit of screw fastening time”, if the lower limit of screw fastening
time is set to 0 sec. (OFF), the electric screwdriver does not start.
You must set a numeric value for the lower limit of screw fastening time.

Depending on the fastening conditions, the screw may not be loosened when in reverse rotation.
Increase the reverse speed level. If the screw is still not loosened, the “Reverse after torque-up” function cannot
be used. You must use “Reverse after the lower limit of screw fastening time.”
