➊
Height adjustment (Fig. A)
The purpose of this adjustment is to set the
rotational axis of motor B to the shoulder
level. To achieve this, the pivot of motor B
must be at the same level as the pivot of the
shoulder joint (see illustration in 4.2.3).
This adjustment is performed with the crank
handle for height adjustment (8).
➋
Shoulder width (Fig. B)
The purpose of this adjustment is to laterally
line up the rotational axes of motor A and
motor B with the shoulder joint. To achieve
this, the pivot of motor A and the pivot of
motor B must be set to the same width as
the pivot of the shoulder joint (see illustra-
tion in 4.2.3).
This adjustment is performed with the crank
handle for width adjustment (9).
➌
Depth adjustment of the
backrest (Fig. C)
The purpose of this adjustment is to set
the rotational axis of motor A to the same
depth as the shoulder joint. To achieve this,
the pivot of motor A must be at the same
depth as the pivot of the shoulder joint
(see illustration in 4.2.3). Furthermore, this
adjustment guarantees a more comfortable
position for the patient on the chair during
the treatment.
This adjustment is performed with the crank
handle for depth adjustment of the backrest
(10).
➍
Upper arm length (Fig. D)
The device for adjustment of the upper arm
length is self-locking. During adjustment,
slightly lift motor C and ensure that the
insertion tube does not jam.
• Loosen clamping lever (16) and slightly lift
motor C during adjustment.
• Perform the desired adjustment.
• Tighten the clamping lever.
➎
Elbow angle (Fig. E)
The rotational axis of motor C must be
aligned with the shoulder joint such that the
rotational axis of motor C goes through the
upper arm to the pivot of the shoulder joint
in rotation (see illustration in 4.2.3).
In most cases an angle of 90° to 60° is
adjusted for elbow flexion.
• Loosen locking screw (18). To facilitate
the adjustment, slightly lift motor C.
• Complete the necessary adjustment and
tighten the locking screw.
Note!
If the elbow angle is changed to a flexion
of less than 90°, the setting for the upper
arm length needs to be changed, too.
The maximum adjustment range is from
0° to 90°.
➏
Forearm support (Fig. F)
The rotational axis of motor C must be
aligned with the shoulder joint in rotation
(see illustration in 4.2.3).
In most cases, the forearm guide (red mark)
is set to the adjustment point 15.
• To change the adjustment, loosen clamp-
ing lever (26) and adjust a length where
the rotational axis of
motor C goes through the upper arm to
the pivot of the shoulder joint in
rotation.
• Tighten the clamping lever.
➐
Forearm length (Fig. G)
• Loosen clamping lever (23) and pull out
the hand rest (25) until the forearm can
easily be accommodated between elbow
support and hand rest.
• Tighten the clamping lever.
