15. Slowly and carefully without paper lower the upper knife by turning crank [R]. 

Check that the upper knife does not contact the lower knife. In that case, back 

up the upper knife and start over from step 3. If no contact proceed to the bot-

Trim the set by turning crank [R]. 

Inspect the trim result. Check if the lowest sheet of the booklet is cut clean 

throughout the length. 

If good, trim and inspect the 15 sheet booklet the same way. 

If good, trim and inspect the 20 sheet booklet the same way. 

If the set is not correctly cut on one of the ends, loosen the five screws [I] & [H]

screws [I] tightened. 

Turn screw [M] in the middle 1/72 revolution or 5°clockwise (   x1).  

Repeat from step 11.
