Dismount the piston from the wire, see item 6,
pos. 2. Guide the wire to the main rack and the
core tube and mount the piston again. To ensure
the piston will be in right position during the
sample taking, adjust the wire-tightener, so the
wire can be moved easily by hand, but the piston
will remain in the core tube.
Guide the wire (with the swivel in front) through
the main rack and the corer tube. The swivel must
remain at top of the main rack).

Mount the wire with the swivel part at the piston
outside the end of the corer tube. Then press the
piston into the corer tube on level with the corer
edge. The photo shows an older model. For a
correct photo of the piston, see next item.

The piston for piston corer function.
When the sample has been taken, there is a huge
vacuum at top of the piston and pulling the white
cord will align the pressure. Otherwise it’s very
difficult to remove the corer tube.

Tighten the PE-HD arrangement a little bit to
ensure against a piston fall-out at sudden
movements. Use bolts J and K.
