10.6 Whirl replacement.
To carry out this operation, proceed as follows:
- Turn off the main switch and disconnect the machine cable from the main supply.
- By turning the handwheel n.6415.00, bring the graduated cam, n.6406.00 to 0.0 position.
- Place the horn curve to the left of the operator.
- Unscrew the screws that fix the whirl cover plate, and slide it out.
- Unscrew the two grub screws n.90503.5 which fix the point feeder, and remove.
- Replace the whirl making sure that the small eccentric hole is directed towards the operator’s right side.
- Insert the tip, fixing it in position with the two grub screws, starting with the first one
from the top of the horn.
Warning:
if the housing of the tip of the horn (where the whirl is) has worn out too much, the whirl may have an
unusual wear, or a very rapid wear, or may work badly even if recently changed. In this case, change the tip
of the horn or use whilrs with a larger size (n. 0533M).
