Operating Instructions
Positioning - Seated
1.1
Footplate/lower leg length adjustment.
For sitting comfort, and to be properly positioned to obtain a standing posture, the seat to foot-
plate dimension must be set to the appropriate length. When doing so, it is important that the
seat cushion that client will be using on a regular basis is used.
When setting the lower leg length, the upper leg position should be parallel to the seat rail, but slightly
elevated from the cushion at the front edge. The result is appropriate pressure distribution for the
thighs and buttocks when seated and appropriate hip rotation and extension when standing.
This adjustment is done by removing the Footrest Length/Angle Adjusting Screws located on
the lower part of the downpost. The vertical adjustment is made in .8 of an inch increments.
These same screws are utilized to adjust the footplate angle (to plus or minus 5 degrees).
1.2
Chest strap height adjustment
To obtain optimum support for the user, especially when standing, the height of the chest strap
can be adjusted. The higher the chest strap is moved up the backrest, the greater support it
will offer. Make certain to weave the backrest straps (which are part of the tension adjustable
back system) through the metal retaining rings found on the chest strap.
Please note that additional support straps are available if more support is desired. Please
contact customer service with questions.
