The tools are durable and simple in design, but as with
G
all things, problems may arise. Refer to this trouble
shooting guide for answers to some of those prob-
lems.
Bent Cable. If a cable becomes bent, attempt to
straighten it. If the bend can't be sufficiently repaired to
allow operation then it will have to be replaced. If the
bent cable is located in a nonessential area then note
this on the order form and cushions can be produced.
A bent cable is easy to find on the computer and its
position can be adjusted.
Data Form put into Wrong Imprinter. This really
isn't a problem. Make sure to indicate on the form
which sensor made the impressions.
Footrest Length. There can be times when the foot-
rests can't accommodate the clients leg length. Use
any surface available such as books or boards to sup-
port the feet. The feet need to be supported for the
legs to be positioned properly.
Jammed Data Panel. This condition can be averted
by always confirming the panel is seated properly in
the receiving channels before pushing it into the im-
printer. When a jam does occur, firmly grasp the stuck
end of the panel with a pair of pliers and pull it out. If
you pull too hard on the cord style handle it could break
away from the panel. If this technique does not work,
then the sensor should be returned to the factory.
Plunger Disconnected. When a plunger becomes
disconnected simply snap it back over the ball end of
the cable. If the cable is pressed down into the foam,
then depress the foam cell around it, and pull it back
up. If the ball end of the cable is broken or missing
then it will have to be replaced. If the damaged cell is
located in a nonessential area then notify this on the
order form and cushions can be produced. A stuck or
broken sensor is easy to find on the screen of the com-
puter and its position can be adjusted.

Seat Depth Won't Lock. If the seat depth can't be
locked, and the knob keeps spinning, then remove the
back sensor panel and slide out the side plate. In-
spect the carriage bolt that attaches the knob to the

seat. The
side plate. Chances are, the edges of the bolt have
worn, and a new one should be installed.

TECHNICAL NOTES

Periodic maintenance of the Shape Sensor and Sil-
houette
tion regarding the care of the cushions and interfacing
®
seating sys-
should be passed on to the client.
Shape Sensor
Keep the slotted seat rail free from debris.
If the Shape Sensor is used to make ContourU
ions, then plaster should be prevented from getting into
any moving parts and surfaces kept clean.
Replace the gas cylinders when they no longer lock in
position.
Check before each fitting that the clamping blocks,
used to fold the frame, are securely tightened.
Do not store objects on top of the Shape Sensors seat.
Cushions and Interfacing
Wash the covers in cold water and tumble dry on low
heat.
Do not immerse the cushions into water as they are
made from open cell foam and will soak up water like
a sponge. The urethane coating does not make the
foam waterproof only water resistant. If the cushion
must be immersed, then squeeze out the excess wa-
ter and dry thoroughly before returning to service.
Periodically check the fasteners that hold the interfac-
ing hardware, and tighten if they have become loose.
Data Forms
The data forms are used to record the contour of the
client and are clearly marked for installation onto the
data panels. There is a form for the seat, and a form
for the back. There is a front and back to the back
form, and a top and bottom to the seat form. Inspec-
tion of the data form will show 50 rows along the
Topshape and 50 rows along the Bottomshape, Each
one of these rows corresponds to one of the plungers.
A finished data form should have imprinted upon it one
base line and one contour line. Always bring duplicate
forms to a fitting in case one is incorrectly printed.
Tear off the side stubs along the perforations and dis-
card the portion of the foam with the adhesive.
