## In short

If the particle size of the ground product has changed, the most common cause is the screen guide sealing rubber, which must be replaced.

- With the mill switched off, scrape off the old rubber and clean the surface well.
- Glue the new rubber with contact adhesive and wait a few hours before grinding again.
- Also check that the screen is not worn or damaged.
