12. Check the adjustment of the sensing switch fingers again, see
Chapter 8.3.

timing, contact the Siemens service.
14. Set the middle cover back in place.
15. Close the lid.
When glass slides are not satisfactorily stained or pump volumes do not
appear to be optimum, check the staining process first. If necessary, correct
and verify the pump volumes.
To check the staining process, proceed as follows:
1. Raise the lid.
Note: After completing each of the following steps, load several spare
smeared glass slides and check the result. If any of these steps corrects
the situation, you do not need to correct the pump volumes.
2. At the right side of the system, observe the circular bubble level to check
if the leveling feet have been properly adjusted and the system is level.
The bubble in the circular bubble level should be centered within the
inscribed circle.
• If so: Go to step 4.
• If not: Go to Chapter 8.2.
3. Make sure the Hematek Stain Pak has been vented, see Chapter 7.2,
step 9 to step 14.
4. Clean the platen, see Chapter 6.4.
5. Make sure that there is no residue in the two mixing grooves, see
Chapter 4.1.2.
6. Clean the drain troughs, see Chapter 6.6.
7. Check the adjustment of the sensing switch fingers, Chapter 8.3.
8. Replace the pump tubing, see Chapter 7.3.
9. Replace the underplaten tubing, see Chapter 7.4.
10. Correct the pump volumes, see Chapter 8.5.2.
