can be rotated. Adjust the fitting in the desired position and fasten the “bolt elbow fitting”.
2 Adjusting the position of the elbow fitting: loosen one or multiple set screws of the elbow
fitting. Adjust the elbow fitting by shifting this fitting in the direction of the arrow. Fasten all
set screws of the elbow fitting.
Adjust the balancing force
Warning: Adjusting the balancing force can result in forces that are higher than the mass
of the arm, resulting in an upwards movement of the arm.
The upwards balancing force can be adjusted by turning the adjustment knob. The force
required to rotate the adjustment knob can change depending on the position of the human
interface. This is normal behaviour. Because of this, the system can be adjusted using little
force. Rotating the knob clockwise will give more balancing force, counter clock wise will give
less force.
• At the top of Dowing

there are two eject knobs. Pressing these two towards each other
makes it possible to remove the human interface, containing the loadarm, arm fitting, elbow
fitting and wrist support.

Adjusting the arm fitting and elbow fitting
To move the arm freely the weight of the arm is balanced. To balance the arm in the vertical
direction, considerable forces are required. For safe use it is important that:
• the arm is positioned in a stable way in the arm fitting
• the arm is always in contact with the elbow rest
If you notice that the arm is not stable and tends to slip out, reposition the arm in the proper way.
Warning: The positions of arm fitting and elbow fitting are crucial for the performance
of Dowing
2
. Changing these positions can result in a severe decrease of the performance
or even malfunction of Dowing
2
. Therefore only trained persons are allowed to change
the settings of the arm fitting and elbow fitting.
Warning: Adjusting the arm fitting can result in malfunction of Dowing
