• Make sure that you do not have any fingers between the basic body
and the plunger!
• Build up some pressure force by moving the hand lever (B) forwards and
backwards until the pellet (PR) and the pressure pieces are ejected from the
die tool.
• Open the shut-off valve (H) by turning in an anti-clockwise direction.
• Remove the pressing plate.
Fig. 14: Removing the pellet
• Remove the pellet.
CAUTION
Risk of fingers being pinched
The plunger is loose! This means that there is a risk of the plunger (M) dropping
downwards when you take the die tool out.
• Hold the plunger (M) securely when removing the die tool!

• Close the side shut-off valve (H) by turning in a clockwise direction.
• Move the pump lever (B) very slowly several times forwards and backwards
until the pressure cylinder (J) moves approximately 1-2 mm upwards.
• Now open the shut-off valve in an anti-clockwise direction. This moves the
pressure cylinder downwards again.
