7.6 Changing the press plunger

In order to facilitate the changing of the

press plunger, we recommend lowering the

press plunger manually by using the

corresponding option in the menu

"Maintenance".

1. Remove the screws (55) and the press

drive cover (52) while the furnace head is

closed.

2. Loosen the terminal screw (57) for the

press plunger with approx. half a turn.

3. Open the furnace head with the corre-

sponding key (112). Once the furnace

head is completely open, switch off the

furnace, disconnect the power, and allow

the furnace to cool to room temperature.

4. Move the press plunger (56) into the

ﬁring chamber by pushing it with one

hand and pulling it with the other while

rotating it slightly.

Contraindication

Take care not to buckle the

thermocouple located in the upper

part of the ﬁring chamber.

5. Insert the new press plunger (56) with

the red mark into the guide bush with

the phasing (inclination) ﬁrst. Push the

plunger into its split taper socket (6) by

rotating it slightly. Tighten the screw (57).

6. Reconnect power and switch on the

furnace with the I/O switch.

Never reach into the press drive

during operation. There is a risk of

crushing.

Wait until the furnace head closes automati-

cally. Remount the press drive cover (52) and

tighten the corresponding screws.
