FRITSCH PULVERISETTE 13 premium line - Manual (Page 43)

16. Open the grinding chamber and slide the locking spanner as far as
possible through the hinge of the grinding chamber.
Depending on the wear on the old grinding disks, the
position of the retracted movable grinding disk may
mean that the locking spanner will not fit behind it
any more. From point 14, positioning behind the mov‐
able grinding disk is no longer necessary. The locking
spanner should be used to secure the door of the
grinding chamber for simpler handling when inserting
the fixed grinding disk and the funnel.
17. Insert the fixed replacement grinding disk and fixate it with the
hexagon screws. Fasten the disk with the locking handle (K).
Be careful when opening it to insert the fixed replace‐
ment grinding disk.
18. Insert the funnel again in the reverse order of what is shown
under point 11 and screw it tight with 3 cylinder screws. (See point
9 to 11)
19. Remove the locking spanner (B) again and close the grinding
chamber manually.
20. Connect the mains plug, turn the device on and lock the grinding
chamber by pressing the locking button (h).
21. The zero point needs to be specified again. (See Ä Chapter 6.3
‘Setting the zero point’ on page 25).
