required torque screws, nuts, studs and any other kind of
threaded connection on any material. Obviously, it is possible
to use the screwdrivers with screw having a larger diameter
if the torque falls within the indicated range. All models are
reversible and can consequently be used to unscrew. Electric

5. Offset calibration screwdriver

(ECL Model)
When the screwdriver is used for the first time, we suggest
to calibrate the offset in the control unit so that the full
range of torque may be achieved.
Please follow the instructions of WTS station
a) Switch the control unit OFF
b) Connect the screwdriver in order to run clockwise
c) Push start and keep on pushing
d) Switch the control unit ON
After 5 secs, the motor will start running at different speeds
until the end of the offset cycle.
Repeat this procedure either in L and H range.
Do this once; it will not be necessary to repeat it anymore,
unless you change the screwdriver.
- Torque setting Clutch Model:
The "TORQUE" knob and the H/L torque switch no longer
have any function and the operator can set on the control
unit only RAMP and SPEED.
The torque is adjusted by varying the compression the
clutch spring, tightening or untightening the threaded collar
after loosening the lock nut.
To increase the torque, turn the threaded collar clockwise.
To decrease the torque, turn counterclockwise. On the
clutch ring there is a scale label to help to set the torque.
The value must be considered merely indicative (the clutch
may also work 2 - 3 mm below the minimum level, but it is
important that the clutch shots correctly.)
