Kajak Sediment Sampler
Brief description:
The KC Kajak Sediment Core sampler is based on the Kajak
design and can be used as a line operated unit, as well as a
hand operated sampler with poles (to be ordered separately).
For a depth of 4 m, you will require 13.302; for 6 m, you must
add an extension pole 13.303.
This model is a quick-change model and speeds up the changing
of corer tubes; very useful if you need many samples. The
sampler can also be equipped with AISI 316 stainless steel corer
tubes.
The upper part of the sampler can be exchanged with a shaft to
sample by manual insertion of the tube. The shafts are made of
AISI 316 stainless steel tubes, each 2,0 m. They can be
assembled to a maximum length of 6,0 m.
The system supports use of inner liners, carvers and orange peel
for higher performance.
An adapter (optional) can be added for supporting 80 mm
sample tubes.
Do not use alcohol for cleaning acrylic
parts
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.

Preparation
1
Rinse the interior of the Kajak with fresh water. It is
important, that both O-rings are clean, as they help
securing the vacuum during the sampling. The rinsing
will also reduce wear and tear of the O-rings.
We recommend smearing the rubber bung and the O-
rings with silicone grease (or spray) to ease the
insertion of the sample tube.
If the O-rings are cracked, worn or damaged, you can
replace them using these dimensions:
Upper O-ring: Ø55 x Ø5 mm
Lower O-ring: Ø59,5 x Ø3 mm
2
Place the upper part of the corer horizontally and
insert the sample tube in the upper part. Press the
corer tube firmly into the core head, so the end of the
tube hits the upper O-ring. A rough guideline says that
you must insert the upper 55 mm of the tube into the
core head to secure the vacuum.
Turn the quick lock in clockwise position. Be sure to
fasten the handle to avoid losing the sample tube into
the sea. Stainless steel tubes have an eye for
attaching a safety line to the Kajak.
IMPORTANT
Smear the rubber bung with a thin layer of silicone
grease before use.

Mount the necessary number of weights and secure
the bolts. Max. mounting of 12 weights = 12 kg.
Standard delivery includes 6 pcs of weights and
threaded bars accordingly.
A larger qty. of weights requires 2 threaded bars,
ordering no. 13.007.
To ensure a permanent vertical position, you must
mount an equal number of weights to both sides of the
weight station.
4
Before you ease the Kajak corer over the rail, press
the movable part (in which the blue rubber bung is
mounted) upwards, until the 2 lock-arms slide into the
notch of the bar.
The Kajak Corer is now ready for lowering into the sea.
5
The correct penetration of the seabed is achieved
during some tests, as it depends on several conditions:
Type of seabed, the lowering speed and the number of
weights on the Kajak Corer.
6
Hard seabed:
Taking samples in a hard seabed demands a carver to
protect the sample tube. Mount the carver by turning
clockwise and secure. You will need tubes with
threaded end to mount the carver.

Soft seabed:
For soft bottom samples, you might need the orange
peel system to prevent the sample from exiting the
tube. Can only be used with model 13.030 (Quick
change) as it will only fit into stainless steel tube,
model 13.533.
8
Assembly of orange peel system and carver for the
stainless steel tube. Insert the PP (Polypropylene) liner
to hold and store the sample for later analysis.

9
When the sampling has been finished, you can seal it
for later research by inserting rubber bungs at each
end of the tube.
IMPORTANT
Smear the rubber bung with a thin layer of silicone
grease before use.
Ejecting the sample
10
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.

Attach the fraction tray to the end of the sample tube
and secure it by turning the wing nut. Insert the piston
into the tube and push out the sample. The small plate
can be used for cutting a small, thin sample of a few
mm.
Mounting the adapter for 80 mm sample tubes
12
Adapter (13.050, optional) for 80 mm tubes
The adaptor for 80 mm tubes is mounted in the Kajak
like the tubes, see item 13.
13
Insert the adapter into the Kajak body as per item 1.
Turn the handle clockwise to secure the adapter in the
Kajak.
Insert the 80 mm tube into the adapter and secure it
by turning the handle in clockwise position.

Mounting the extensions poles
14
When operating the Kajak in shallow lakes, the upper
part of the sampler is exchangeable with a shaft
(optional) to sample by manual insertion of the tube
into the sediment.
Remove the lock mechanism by unscrewing 2 nuts, A
+ B and removing 2 washers. The spring, C, has been
loaded and you must secure it by fingers to avoid
losing it.
15
Push down the spring, mount the shaft and secure the
nuts, A + B. Attach a polyester line, or similar, to the
hook (C).
Before lowering the sampler in the sea, pull the line to
allow a free flow through the sample tube. Once, you
have taken the sample, release the line and the bung
will close, ensuring a vacuum in the sample tube.
16
The poles are made of AISI 316 stainless steel tubes,
each 2,0 m. They can be assembled to a maximum
length of 6,0 m.

Assembling the shaft:
Push the shafts together and align the holes. Insert the
wingnut and fasten it.
Storing and Maintenance
18
Remove the sample tube or 80 mm adapter from the
core head.
Wash all parts with fresh water.
For storing the Kajak, please tie up the part as shown
to prevent the bung from being jammed in the
stainless steel top. Otherwise, it is very difficult to
separate the parts as the bung might expand a little.
All parts of the item can be rinsed using salt water or
fresh water. Before storing, we recommend a
thoroughly cleaning with fresh water.
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.
