Adjusting the spacing of thigh supports
Thigh support spacing adjustment is done using two adjustment screws below the supports (fig. 3). In order to make the
adjustment, raise the upholstery on the thigh supports and loosed the adjustment screws to position the supports
appropriately. After setting the desired position, tighten the adjusting screw to lock the supports in place. Thigh supports can
be positioned at an angle to the longitudinal axis of the device, thus increasing thigh angle. Thigh support positioning has an
impact on the correct position of knees in relation to the pelvis.

The adjustment screws are located on the right and left sides of the device. Their effect is independent of each other. This
enables symmetrical and asymmetrical positioning of the user's body.
NOTE:
After adjustments are made, make sure that all the adjusting screws are tightened. Failure to tighten
them may be hazardous to the patient and may damage the device.
4.1.3
Adjusting the depth
Seat depth can be adjusted by sliding the back of the device into or out of the base. Adjustments should be carried out with
the device in the full sitting position.
In order to make the adjustment, loosen the knobs on the side pulls (fig. 4) on the right and left sides of the device, then
loosen the securing screws located underneath the seat (fig. 4) on the right and left sides. Next, insert or pull out the rear of
the unit (backrest and actuator) to obtain the desired depth of the seat. After adjustment, tighten the previously loosened
screws, pulls and securing screws.
