lights up.
The BB 51 is now ready for operation.
Set gap width to 00.0
The gap width must only be adjusted when the machine is empty.
There must be no input material in the crusher chamber or feed
hopper.
Before starting the BB51 turn the handwheel
F
through two revolu-
tions anti-clockwise so that the crusher jaws are out of contact with
one another.

Before adjusting or starting the BB51 you must turn the handwheel
F
through two revolutions anti-clockwise.
The crusher jaws are then safely out of contact with one an-
other, thus preventing jamming and possible damage to the
jaws of the BB51.
Adjustment should be carried out regularly so as to ensure that the
indicator display and the actual gap width tally. The greater the load
on the BB 51 and the harder and more abrasive the input material,
the more often a zero point adjustment must be carried out in order
to compensate for wear.
The reading on the indicator display will otherwise not tally
with the actual gap width.
The BB 51 must only be adjusted when the machine is empty.
Jamming will result if there is any material in the crusher chamber or
feed hopper before starting.
This may result in damage to mechanical components.
