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.
