FRITSCH PULVERISETTE 14 - Manual (Page 42)

7.3 Intake filter
On the back side of the PULVERISETTE 14, the intake area for cool air
entering the device is protected with a filter mat so that only relatively
dust-free cool air is taken into the device.
NOTICE!
Maintenance of this filter mat is absolutely required. The
drive motor is not sufficiently cooled when the filter mat is
excessively soiled. This results in motor failure.
Inspect the filter mat (order no. 83.1120.00) regularly and when neces-
sary rinse it out with running water or replace it.
