Operating the machine

38

The PM400 is fitted with a fan which extracts the waste heat created during
grinding directly out of the grinding chamber. The extraction volume per hour is
greater than 20 times the grinding chamber volume. The fan has standstill
monitoring with signalling.

The airflow from the fan during grinding can be discharged into an extractor hood if
necessary.

Check that the locking mechanism is secure before removing the grinding jar.

Only remove grinding jars with locking mechanism, and only open after cooling
when in a safe position (extraction device).
