follows:
NOTE:
Check that the geometrical characteristics of the die are suited to the model of machine used.
?
Select the adjustment cycle
?
Lock the slide to T.D.C. using the INDUSTRIAL PC.
DANGER:
Any operation other than the loading / unloading of pieces carried out inside the danger
zone of the press should only be carried out after the safety stop has been operated
correctly.
?
Bring the blank holder to T.D.C. by pressing the “CUSHION UPSTROKE” button situated on the control
console.
?
If the die requires the blank holder to be used, insert the pressure pins into the holes in the table after
greasing the surfaces of these.

If the die requires the blank holder to be used, activate the downstroke of the blank holder using the
“CUSHION DOWNSTROKE” button on the control console (bring the pressure pins just under the work table
of the press).
?
Clean the upper part of the table and the lower part of the slide carefully using a detergent and a lubricant.

Position the die on the table of the press using a forklift truck with adequate lifting capacity for the weight to
be lifted.
DANGER:
For the correct handling of the die, refer to the operation manual supplied by the
manufacturer of the die and follow the safety instructions contained in it.

After having centred the die on the press table, lock the lower part of the die using screws and DIN 508 “T”
nuts suitably positioned in the DIN 650 “T” slots in the table itself.
?
Release the slide from T.D.C. using the INDUSTRIAL PC.
?
After having released the slide, activate the downstroke of the slide until contact between the upper part of
the die and the slide becomes possible.
?
Lock the upper part of the die using screws and DIN 508 “T” nuts suitably positioned in the DIN 650 “T” slots
in the slide itself.

Store the new cam position (for the slide and blank holder) in the INDUSTRIAL PC memory based on the
loaded die and bring the slide and blank holder to T.D.C. If the die has already been used, recall the work
program for the loaded die.
