3.2.2) Lower die
– Using a 5 mm allen key, loosen the clamp screw (06).
– Insert the die into the housing in the lower die support (07) making sure that the impression is
facing upwards; the coloured reference mark on the die should correspond with the mark on the
lower die support (07).
– Leave the clamp screw loose and fit the appropriate safety guard (see § 3.3).
– Press and hold the manual control (26). The machine will cycle, the upper die will touch the lower
die and ensure correct alignment of the dies.
Continue to hold the pedal and tighten the clamp screw (06) to lock the lower die in position.
– Release the pedal.
N.B.: for "high and low" positioning of dies without reference marks (type MTT...-50, MN... RF-50) see
the relative figures given in the tables on pages 32 and 34.
Symmetrical dies may be positioned as required.
3.3) Fitting the safety guard
– Position the guard on the press and insert the pin (21) attached to the rear of the guard, into the
main body (12).
– Tighten the knob (23) into the die support (07). The guard will move forward, activate the safety
devices and switch on the air feed.
– The press is now ready for operation.
3.4) Die removal
When changing dies proceed as follows:
– Turn the main air valve (16) to the "EXH" position.
This cuts off the air supply and discharges any air pressure within the machine.
– Remove the safety guard.
– Unscrew clamp screw (10) and remove the upper die.
– Unscrew clamp screw (06) and remove the lower die.
– Insert the replacement dies (see 3.2).
3.5) Oil top up
Every six months check the oil level, using the dipstick on the oil filler cap (14).
The level should be between the two reference marks. If necessary, top up with the recommended
oil (see 1) to the "MAX" mark.
Ensure that disposal of used oil is in accordance with current legislation.
