Model no.

This Van Veen grab is 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.
Preparation:
1
Standard delivery includes 4 lead weights, each 1
kg. It is possible adding 4 more weights (requires
longer bolts 6 x 80 mm). Use lock nuts so you do
not lose the lead weights.
2
Place the grab on a plain, stable surface. Force
both arms down to horizontal position so the grab
is open.
Press the locking pawl upwards to lock the arms.
For security remarks, please see item #4.

Still lifting the pawl upwards, pull the wire tight as
shown on the photo. The grab is now locked in this
position.
4
The grab is now ready for deployment. Attach the
wire for deploying the grab to the eye of the wire.
Keep the wires on the grab straight to avoid an
unintended release of the locking mechanism.
5
Handle the grab with care to prevent injury to
personnel. Fingers and hands may be stuck at the
arms and by the jaws.
Emptying the grab
6
The grab has 4 lids and turning the knob counter
clockwise the appropriate lid can be open and you
can take out a small sample without emptying the
whole sediment sample.
Empty the whole content of the grab by forcing the
arms of the grab into horizontal position.
Each time you handle the grab, take care to avoid
any injury.
Maintenance
All parts of the Van Veen grab can be rinsed using fresh water. We recommend regular
cleaning with fresh water before storing the sampler. Turn all moveable parts during the
rinsing to remove all the dirt.
