Fig.12 Upper guide adjustment
1. Using a pre-scored PCB, check the clearance „A“ between the upper guides (1,3) and the lower blade (4). The
clearance should be set so that the edge of the upper guide is located correctly into the pre-scored groove of the
PCB. The PCB can be smoothly moved backwards and forwards but cannot move sideways.
The upper guides (1,3) prevent the PCB from slipping to the side and therefore ensures that it is not separated
other than at the pre-scored groove.
2. As required, the clearance A should be adjusted as described above by turning the eccentric adjusters (2).

Fig.13 Table adjustment
To suit the MAESTRO 4M to differing requirements, the height of the table can be adjusted as follows:
1. Loosen the knurled screws (7) located on the inner side of the machine frame.
2. Lift the table (5) slightly and move it towards the rear until the stop.
3. Slide the table on the slots (6) and mount it at the height required.
4. Pull the table gently forwards until it locks into place.
5. Tighten the knurled screws (7).
6. Whilst the knurled screws are loose, the table can be removed completely from the machine frame as the
elongated slots (6) have an opening underneath. Complete removal of the table is required especially for
replacement of the lower blade or mounting the optional conveyor belt.
Additionally, by sliding the table towards the rear it is possible to form a space between the table and the lower blade
through which the edge strips of the PCB can fall through into a container placed underneath.
