9) Reverse:
This option will automatically start a reverse cycle after a torque reached signal. You can set
time from 0.1 to 20.0s.
To disable the function select OFF by pressing
ATTENTION: During the reverse cycle, it is necessary to keep the lever pressed or the start signal high
for as long as you want the screwdriver to run. If this is done correctly the message "Correct screw" will
be displayed on the status bar and a green led will light up. You will hear one "beep" sound, too. If this is
done incorrectly and the lever is released or the start signal goes low before the end of the reverse cycle,
"unfinished screw" will be displayed and a red led will light up. You will hear two "beep" sounds, too.
10) Rev speed – Reverse speed:
maximum & minimum speed specified in the catalog (see table with technical data).
11) Rev torque – Unscrewing torque:
range of a given screwdriver (see point 2). If the torque is set on MAX, the unscrewing torque is about 20%
higher than the possible maximum torque, so that it is always possible to unscrew the tightened screw (we
suggest leaving this function on in normal use). If the setting is from MIN to 99% the unscrewing torque
will be the same percentage.
ATTENTION: If you're using open end "tube nut" wrench blades, the unscrewing torque must be set
to MIN value in order to bring the wrench back to the correct position.

13) Max torque:
This is the period of time in which the screwdriver works at maximum torque before
down shifting to the torque that has been set by the user. You can set time from 0.1s to 10.0s. To disable the
function select OFF by pressing
This function overlaps other time settings (brake time, ramp time, minimum time, maximum time) from the
motor start on.
ATTENTION: This function is useful for applications where the prevailing torque is higher than the final
torque (for example trilobe screws or locknuts).
Please use this function with utmost attention because an incorrect use can damage both the assembly
and the screwdriver.
