Small Free Fall Corer
The Free Fall Corer can be very dangerous in unskilled hands, and you must
take serious precautions to avoid accidents.
KC Denmark A/S is not, and cannot be held, responsible for any damage(s)
made to equipment or to operators who ignore safety precautions or because
of misuse or wrong operation.
Item
Preparation
1
Place the upper part of the corer in horizontally
position and insert the stainless steel tube in the upper
part.
To prevent losing the sample tube, attach the snap
hook to the ring at end of the sample tube.
2
Fasten the tube by turning the handle “A” clockwise.
3
If the upper layer of the sediment must remain
undisturbed, you can leave out the liner and the
orange peel system.

To prevent the sample from exiting, you can add the
orange peel closing system. It consists of the following
parts:
A –Carver
B - Orange Peel
C –Liner
4 –Steel tube
5
Insert the orange peel into the liner.
6
The orange peel is now located into the liner.
7
Fasten the carver by hand to secure the orange peel.

8
When sampling half-hard or clayey sediments, attach
the carver and you can leave out the orange peel
system.
You can use the steel tube with no liner for sampling,
but due to the steel tube’s locking ring at the top, see
photo, you cannot use the piston rod for ejecting the
sample.
If you intend to use the liner without the orange peel
system, you must insert a steering ring (13.527) to
centre the liner in the tube.
9
Adjust the number of lead weights for your purpose
and secure all bolts. Always use the same qty. on each
fin to keep the balance of the corer.
The corer has room for a maximum of 24 pcs lead
weights, each 2 kg.
10
Ensure the lid will close firmly to the top of the tube
and no sediment will disturb the closing function.

11
Lower the free fall corer at a reasonable speed to take
the sample.
Ejecting the sample
12
After raising the corer, dismount the carver and the
orange peel system. Take out the internal acrylic or PP
tube.
For later analysis, you can secure the samples with
rubber bungs or caps at the tube’s end(s).
For ejecting the sample into smaller parts, adjust the
small crossbar accordingly.
Due to small variations in the inside diameter of the
pipe, it may be necessary to adjust the nut at the end
of the piston. Check regularly that the nut does not
come loose, so the steel bar may fall off.
13
Using the fraction tray demands that the sample tube
is positioned in vertical position. Add the fraction tray
on top of the tube and secure with the wing nut on the
black part of the tray.
The small plate can slice off the visible sample.
Storing and maintenance
14
Before storing, rinse the sampler thoroughly using fresh water. Store in open position, so the
inner parts will become dry.
Do not use alcohol for cleaning acrylic parts.
Items, like PP/PVC/acrylic tubes, rubber seals, motor houses with or without Fluorinert, etc.,
and a long exposure to direct sunlight or lack of clean up for salt water might affect the
durability and stability of the products and will remain uncovered by the warranty.
Replace worn component with original spare parts.
