The Ottobock System Hands –passive– perform the three-finger grip with
the index, middle finger, and thumb. The passive System Hand is opened
with the sound hand at the thumb and closes under spring tension.
The grip force can be adjusted by turning the oval countersunk head screw
at the bottom side of the chassis (Fig. 1):

4.1 Assembly
The System Hands –passive– are to be mounted to an Ottobock wrist unit.
For long below-elbow and through-wrist residual limbs, the chassis with
threaded stud must be replaced by the chassis with 9E94=* Lamination
Ring as follows:
• 9S96=40
• 9S184=*
These parts are attached with the 506G4=* Set Screw (Fig. 2).
For this purpose, the bore hole for the spring holder must be drilled into
the new chassis (Fig. 1, see arrow).
The 640F18 Donning Spray facilitates the application of the inner hand
on the System Hand.
To avoid any damage, use the 711M1 Hand Holding Tool for holding the
System Hand while pulling on the glove. The 711M2 Mounting Plate is
used for attaching the Hand Holding Tool to a workbench or wall (Fig. 3).
