Adjusting the seat depth
NOTE
–
The seat depth has a major influence on the selection
of the center of gravity of the seat. This impacts its
dynamic stability. If you make a major change to the
seat depth the center of gravity of the seat must also
be adjusted. See "Adjusting the center of gravity of
the seat" in the service instructions for this mobility
device. The service instructions can be ordered from
Invacare. However, they contain instructions for
specially trained technicians and describe operations
that are not intended for the end user.
NOTE
–
The numbers on the scale on the seat serve as a guide.
They do not stipulate any dimensions such as seat
depth in centimeters.
Requirements:
•
1 x 6 mm Allen key
1.
On both sides, loosen the bottom backrest screw
A
.
Do not remove the screws!
2.
Move the backrest to the required seat depth.
You can adjust the seat depth steplessly. Use scale

on the seat
as a guide for this purpose.
Ensure that the same seat depth is set on both sides.
3.
Re-tighten the screws.

Adjusting the seat angle
CAUTION!
Adjusting the seat tilt or the backrest angle
changes the geometry of the mobility device and
directly influences its dynamic stability!
–
For details regarding dynamic stability, negotiating
gradients and obstacles and the correct adjustment
of seat tilt or backrest angle, refer to 5.3 Taking
Obstacles, page 24 and Driving up and down gradients.

other. The adjusting mechanism is at the front under the seat frame.
When adjusting the seat angle, ensure that both fixing screws are
