9.7 Check the Blade Alignment
i
Notice!
When the machine is put into operation for the rst time, or following a move of equipment or a change of
blades, it is advantageous to re-check the alignment of the blades in relationship to one another. For this
purpose a dial gauge assembly (Part No. 8970208) is available as an option.

1. Move the blade carrier (1) to the middle of its range of travel.
2. Afx the dial gauge assembly onto the threaded hole (2) in the blade carrier and screw tight with the knurled
screw (4) provided.
Ensure that the small spigot (5) mounted on the inside of the lever (6) locates correctly into the hole (3) provided
in the blade carrier.
3. Swing the lever (6) upwards until the tip of the gauge feeler (7) presses onto the upper blade (9) at 2 mm of the edge of
the blade. Rotate the scale on the dial gauge until the pointer in the 1/100 mm division is lined up with the „0“ on the scale.
4. Swing the lever (6) downwards until the tip of the gauge feeler (7) presses onto the lower blade (10) at 2 mm of
the edge of the blade..
5. In the event of the values obtained by the above procedure being greater than the values , the servicing agent
responsible for your machine should be contacted.
6. Remove the dial gauge assembly.
9.8 Cutting of aluminium PCB‘s with roller blade FR4
!
Attention!
The using of a roller blade FR4 (cab part No.: 8930509.001) for cutting aluminium PCB‘s reduced the
durability of the blade by higher abrasion.
For using a roller blade FR4 for cutting aluminium PCB‘s it‘s necessary to make a couple of modication:
• implement a side offset between the blades from 0,2 to 0,3 mm
• conrm the lower stopper of the upper blade
