Opening and extraction of the tool. Wait for seal/weld to be cooled before extracting the tool. A count down on the display and an acoustic sound
signals the end of the cooling time. Prematurely opening of the tool could cause an excessive loss of tensioning force and break of the seal/weld with
consequent serious danger for the operator.
Raise the opening lever (1.3) and remove the tool from the strapping plane turning the back of the tool to the right (fig. 8).
Seal/Welding quality control
The seal/welding control is very important for your safety.
Correct seal/welding
Long seal/welding time
The seal/welding efficiency is pour. Decrease the seal/welding time.
Short seal/welding time
The seal/welding efficiency is pour.
ATTENTION! Cut and replace straps with wrong seal/welds. Eventual break of the strap in the seal/welding area could cause serious damages.
Test, periodically, the effective seal/welding efficiency with adequate equipment (for example sending strapping samples to a specialized laboratory for a
tensile tests).
Setting the correct strap width.
This tool can be used with PP/PET strap with width between 3/4" and 1" (19 and 25 mm).
To set the correct strap width, proceed as shown in fig.14.

Special functions

Checking the total number of cycles. The total number of cycles is given as a 6 digit number shown in two different screen shots, 3 at a time, from left
to right. Hold the "+/-" button for more than 3 seconds. The first 3 digits are shown on the display. To show the second 3 digits, press the button "+/-".
Press once again the button "+/-" to exit. The total number of cycles could be used to plan an ordinary or extraordinary maintenance of the tool.
Checking the software version Remove the battery. Press and hold down the welding button and insert the battery. On the display appears the
software version composed by 3 digits. Release the welding button to exit.
Locking the control panel Remove the battery. Press and hold down both tensioning (1.1) and welding (1.2) buttons and insert the battery. An
acoustic signal indicates the lock of the control panel.
The same signal is emitted every time the control panel buttons are pressed with a locked panel.
To unlock the control panel repeat the same procedure.
Maintenance
ATTENTION! BEFORE ANY MAINTENANCE OPERATION, REMOVE THE POWER SUPPLY OF THE TOOL.
The maintenance and repair must be done exclusively by trained personnel. If necessary, send the tool, using the original packing, to the closest
maintenance center.
Daily cleaning. Remove strap residue from the feedwheel and the welding unit using compressed air. It is not necessary to open the tool. ATTENTION!
Use eye protection glasses.
Feedwheel replacement (fig. 10)
Remove the 2 fixing screws "A" of the carter "B" on the left side of the tool. Remove the carter "B".
Remove the 3 screws "C", remove the external flange "D" and the bearing "E". Replace the feedwheel "X" and if necessary, lubricate with lithium
grease with density 0. To assemble the tool, repeat the described operations in inverse order. Use Loctite 243 to fix the screws.
Cutter and seal/welding plate replacement (fig. 11)
Remove the 2 screws of the carter "B" on the left side of the tool. Remove the carter "B".
Cutter replacement: Remove the screw "C", remove the bushing "D" and replace the cutter "Z". Don't forget to insert the cutter spring "E".
Seal/Welding plate replacement: Remove the 2 screws "F" remove the guide "G", remove the pin "H" and replace the seal/welding plate "W".
Replacing of the grippers (fig. 12)
To replace the grippers, remove the screws "A", extract the old grippers and replace them with new ones "Y". Use Loctite 243 to fix the screws.

(fig.9-A) the entire area is to be well seal/welded, without excessive leak of mold material on both sides.
(fig.9-B) wrong seal/welding, the mold material leaks, in an excessive way, on both sides of the seal/welding zone.
(fig.9-C) wrong, the seal/welding area is only partly seal/welded.
Increase the seal/welding time.
