Adjustment Procedures
1. Loop clamp base plate
receiver . First, move sensor
2. Remove the cover located on the right side of the operation
box panel and turn ON SW 2 of the lower side of the DIP
switches which are located both on upper and lower sides
to enter the step operation mode.
3. Turn ON the power and supply air to the machine.
4. Press the set back switch several times to move loop clamp
base plate until it travels to its front end which is before
cross cut receiver .
5. When loop clamp base plate
end, adjust the position of sensor
provided between loop clamp base plate
receiver is 1 to 2 mm.
6. Again, press the set back switch several times and press it
in repetition until the setting screen is displayed.
7. When the setting screen is displayed, pressing the standard
screen key, press ten key 4.
Loop clamp base plate
rewrites the position data.
8. Again, perform the step feed with the set back switch and
check the clearance provided between loop clamp base
plate and cross cut receiver
9. Move clamp end sensor bracket

Results of Improper Adjustment
○ If the position of the adjustment
of loop clamp base plate front
sensor is improper, the loop
clamp base plate interferes with
the cross cut receiving portion
or the belt loop cannot be
securely clamped.
○ When the adjustment of the
clearance is improper, the
sensor interferes with the top
surface of the loop clamp base
plate or the sensor cannot
detect the loop clamp base unit
and interferes with the cross cut
receiver. If the interference
occurs, components may be
damaged. Be sure to check the
clearance before turning ON the
power.
