7.3 Lubrication of the main spindle and the advancing mechanism

19 July 2023/v1.7
Annual service:
1. Remove
mechanism (loosen worm screw (E)), but leave it on
the spindle guide (G).
2. Loosen special nut (A) and remove adapter or crank
handle (J). After removing the key (K), the main spindle
(H) can be pulled down completely.
3. Slowly screw the advancing mechanism upward (C).
Be careful that none of the parts from the spring-
loaded threaded ring (D) get lost.
4. Clean all parts and lubricate them.
5. When screwing on the advancing mechanism (C), be
sure the threaded ring (D) is being fixed again in the
same position. When reaching the guide (G) with the
threaded ring (D), press down the advancing
mechanism (C) in order to reduce the play of the
springs (L) to zero.
6. When placing the main spindle (H), be sure the
compensating spring (B) is properly fixed.
