2.3 Thumb Adjustment.
To achieve certain grips it is necessary to adjust the thumb position. There are two different
planes to move the thumb in, as detailed below.
2.31. Thumb ML Adjuster 2.32. Thumb Contact Point Adjuster
Underside of Thumb Bracket
An adjuster has also been provided to alter the baseline
position of the thumb, in order to optimize the contact
point of the thumb tip against the opposing finger(s)
for Tripod, Pinch and Precision Grips. This is done by
moving the thumb either towards the palm or away
from the palm. This adjuster is located under the thumb
bracket as shown above. Using a hex drive the adjuster
should be turned clockwise to move the thumb towards
the palm and counterclockwise to move the thumb
away from the palm. The effect will not be observed
while making the adjustment and can only be observed
by resetting the hand i.e. switching the hand OFF and
ON again. An adjuster is provided to allow repositioning of the
thumb for contact with either the index and middle
fingers, as in Tripod Grip, or with index finger only, as in
Pinch and Precision Grips. The thumb pivot assembly is
fitted with a slotted screw as shown above. This acts to
adjust the friction on an internal clamp and is loosened
by making two complete turns and pushing the screw
inward. With the clamp slackened the thumb position
can be manually repositioned. The assembly must be
retightened before electrically driving the thumb.
Please ensure screw is securely tightened
before resuming use.
