1. Turn the drum manually until the drum master clamper on the drum moves into
the lowest position. (This is when the high points of the cams on the drum
flanges meet with the cam followers on both ends of the press roller.)
• To find out the correct position of the drum for the adjustment, look at the
rear end of the drum shaft. The recess on the drum drive gear meets the hole
[A] in the bracket when the drum is in the correct position.

loosening the two screws [E].
