TABLET PRESS
3.5 First function test
1. Before carrying out the first pressing attempt, the lever (8) on the stop
valve must be rotated in a clockwise direction to "close" so that pressure
can be built up.
2. Put the pressing tool together with a suitable test material as described in
Chapter 4.2.
3. Rotate the spindle (4) upwards using the hand wheel (3).
4. Open the door (5) to the workspace.
5. Place the pressing tool together with the bottom tool (12) in the centre of
the press on the pressure cylinder piston (6) pressure plate (6a).
6. Clamp the pressing tool by screwing the spindle (4) down.
7. Close the door (5).
8. Move the lever (1) backwards and forwards  the pressure cylinder piston
(6) will be "pumped" upwards. After around 20 strokes, a pressure buildup
will be visible on the pressure gauge (7). Continue pumping until the
pressure gauge (7) reads 250 bar.
9. After this, open the stop valve using the lever (8). Turn it to "open"
 the
pressure cylinder piston (6) will now move slowly downwards.
10. Unscrew the spindle (4)
11. The pressing tool can now be removed and the sample pellet pushed out
as described in Chapter 4.3.
12. The Pellet Press is now ready for operation.
13. If the functions provided by the Pellet press do not correspond to those
described above, the device may not be operated. In this case, please
contact Fritsch GmbH or the representative or distributor responsible for
your company.
CAUTION Never use the the pressing tool without sample material.
This will result in damage to the pressing tool. No guarantee
