Manual for
multi corer, 4 x Ø100 mm
Model no.
71.500
This multi corer is very dangerous in
unskilled hands and serious
precautions must be taken to avoid
accidents.
The safety clamp must always be in
the secured position and must be
released only, when the multi corer
is outside the rail of the boat. Except
for item #5 (water filling of
hydraulic damper).
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.
Never walk under the multi corer,
when lifted up by the winch.
The photo shows another model with
2 pcs of safety clamps.

Preparation
1
The actual design comes with only one safety
clamp.
Attach the safety clamp at the top of the corer,
ensuring the handle is locked properly at “1”.
The photo shows an old model with 2 safety
clamps.
2
Push up the lid. The wire from “A” goes through
the hole at “B” and the end is secured at “C”

3
Lift up the unit and secure the snap hook at “D”,
while pressing the unit upwards tighten the screw
“E”. Don’t use any tools, as the unit must glide
over the bar during release of the sampler.
4
It is very important to attach the snap hook at
“F”. Attaching at “G” will cause malfunction to
the lid.
5
The handle behind the lid will secure the steel
wire from top of sampler to the bottom release
system.
Press down the handle, ensure the wire is taut
and release the handle.

6
The spring loaded bottom lid “H” is pressed
toward the centre of the sampler.
The security pin “I” at the end of the steel wire is
inserted into “J”, so the bottom lid is locked in
open position.
When loaded, you must avoid an unattended
release as the mechanism may cause injury to
people.
7
Open the quick release bracket for the tube
8
Tilt the sample tube to the side, so you can insert
it into the hole, lower the tube for 1 cm, approx.
Align the tube to vertical position.

The sample tube has a reinforcement at the top
10
The reinforcement of the tube is aligned at the
quick release.
Check, if the lower end of the tube is inserted
correct (item 8).
11
Tighten the handle to secure the tube.
Do not over tighten the handle, as you may
damage the tube

12
After attaching the required numbers of lead
weight, you must tighten all locks for the lead
weights.
Adjustable penetration
depth
13
Before mounting the bracket for adjustable
penetration depth (optional), you must ensure,
that the security clamp is placed correctly (see
item 1).
14
The bracket is attached to the bars. For full
penetration, leave the bracket as shown.
Fasten the 4 bolts firmly to keep the bracket in
place.
15
For a shorter penetration move the bracket in
vertical position and fasten by means of the 4
bolts.
16
Extending the corers
footprint
17
Four extension legs (optional) can be added for
better stability in strong currents or for larger
depths.
The hydraulic damper
18
The multi corer has an automatic, hydraulic
damper located at the centre.
Upon lowering to the sea, the damper is filled
up with water through the inlet “K”
When the multi corer hits the seabed, the water
is forced through the outlet “L”, causing a delay
before the tubes penetrate the sediment.
Deployment
19
The multi corer is now ready for deployment.
When the rack is outside the bulwarks, you can
remove the safety clamps “1”.
The photo shows an old model with 2 safety
clamps.
If you must remove the security clamp while
the sampler is on deck, you must avoid an
unattended release to protect against injury.
20
The sampler can now be deployed to the
seabed, and the hydraulic damper will ensure a
smooth sample taking to avoid a shock wave
during penetration.
When hoisting the sampler the sediment tubes
will be withdrawn from the sediment, and the
lids will close to protect the samples from exit.
