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.
2. Using a thickness gauge, measure the clearance [B] between the press roller arm [C]
and the press roller lock lever [D] (rear side). It should be between 0.7 and 1.2 mm
3. If it is not correct, adjust the position of the press roller lock lever after loosening the
two screws [E].
4. Repeat steps 2 and 3 for the front side.
