Emptying the corer tubes
23
Requires the following items:
13.548 – Piston rod + 13.559 extension
13.549 – Drum with ratchet device
13.569 – Detacher for the tube
13.904 – Trestles, see item 32, alternatively
the ship’s deck
Photo shows the tube detacher for removal and
handling of the core tubes.
24
If you cannot remove the sample tube by hand,
use the tube detacher. Tighten the handle, grab
the black handle and turn counter clockwise to
release the tube.
25
Place the corer tube horizontally on 2 trestles (see
item 31) or on deck.
If you have added the extension kit for piston
corer functionality, you must remove the piston.
Operating the corer as gravity corer, there is no
piston.
If you cannot remove the piston due to heavy
vacuum, pull the white cord to align the vacuum.
26
Fasten the ratchet device by means of A and B;
see item 32; it will only fit on the steel tube’s
reinforcement. For the PVC tube, it will fit
anywhere.
Do not over tighten “A” and “B”, as it may cause
damage to the PVC tube; furthermore the piston
may be stuck because of the deformation of the
tube.
