Overhauling the grinding holders
These instructions describe how to overhaul or repair a grinding holder. The polycord
and spring are the parts that are normally changed. It is vital to overhaul all grinding
holders at the same time so that the tools are not subjected to uneven wear. Never use
the same screw twice. Clean all components in the grinding holder thoroughly.
Since the design varies between machine models, the machine pictured in the illustra-
tions may look slightly different from your machine.
1. Remove the grinding holder from the machine: remove the
cross and then undo the three screws (J) beneath.
2. Turn the grinding holder so that you can undo the screws (D).
3. The grinding holder is now split. The spring and polycord can
be changed (H, E).
4. Remove the old spring.
5. Remove the polycord by undoing the screws (G) that are now
visible on the top part.
6. Glue the spring (H) to the lower grinding holder (I). It must be
positioned in the centre. Use Loctite 406 or equivalent.
7. Fit the polycord (E) Thread and tighten the screws (G) into the
top grinding holder (B) (see Fig. 20).
8. Thread and tighten the screws (D) into the lower grinding
holder (I) (see Fig. 21).
9. Protruding screws must be ground down before fitting the
grinding holder.
10. Refit the grinding holders and the cross.
