Warning

Danger of accident! With semi-bowls, two 
different styles are used, which must never 
be mixed. Otherwise, the semi-bowls could 
come loose from the shaft during system 
operation. The two styles differ based on 
the location of the bushels at the end or 
start of the semi-bowl. In order to prevent 
imbalance and damages caused by this, 
the following points must be observed: The 
semi-bowls must always be replaced as 
sets, i.e. always as a whole segment. The 
bristle bushels must be offset to the oppo-
site semi-bowls along the the butt joint.



Place the first pair of semi-bowls on top 
of the shaft and slide them together.



Place the second pair of semi-bowls on 
top of the shaft rotated by 90° and slide 
them together.



Install the other semi-bowl pairs on the 
shaft offset by 90° each.



After installing the last semi-bowl pair, 
install the end clip.



Slide the end clip against the last semi-
bowl pair and tighten screws.



Finally, recheck the proper installation 
of the semi-bowls and tight seating of 
the screws.
