WARNING!
– Crushing hazard when closing the housing cover!
– Crushing hazard when removing and positioning the
collecting vessel!
– The collecting vessel can become very hot!
– Never operate the device without sieve ring, collecting
vessel and lid. If no sieve ring is desired, the spacer ring
no. 44.1110.00 has to be used.
– Cutting hazard at the grinding elements such as rotors,
sieves and collecting vessel. These can have sharp
edges. Sieves with reinforced edges can be used to
avoid the cutting hazard from sieve rings. These do not
have any sharp metal edges.
– When grinding electrically conductive substances, the
fine dust can be suctioned through the filter on the
back side of the device and cause short circuits. There-
fore, when grinding such substances, work must be car-
ried out especially carefully and cleanly.

The main switch separates the PULVERISETTE 14 from the mains on
two poles.

2.8.2 Protection against restart
In case of power failure during operation or after switching off with the
main switch, the housing cover is locked. The lock of the housing cover is
opened when the power returns. For safety reasons, however, the PUL-

switches off the motor after a continuous overload. To rectify the mal-
function, switch off the PULVERISETTE 14 and remove the block. After-
wards, the motor is started by pressing the [ START ] button.
The device switches off when the drive motor becomes too hot.
The PULVERISETTE 14 switches off when the drive is blocked
