General
Cleaning
Cleaning of the BB 300 is best effected with an industrial vacuum
cleaner and a robust, long-handled brush.
!
The feed hopper may only be dismantled by trained specialists, by
removing the eight hexagon screws, for cleaning purposes. Operation
of the BB 300 with the feed hopper removed is impermissible.
Risk of crushing fingers and hands!
!
Do not clean the BB 300 with running water.
Lethal hazard of electric shock
Solvents must not be used, as the felt seals on the sides of the crusher
arms would be destroyed, and grease packing washed out.
