Invacare® Bora® / Spectra® XTR Series
4 Setup
4.1 Adjusting Seating Position
To adapt the mobility device optimally to the requirements
of the user, we recommend that you ask your authorised
Invacare provider to adjust the seat depth individually.
Adapting the seat to the user's seating position depends
on which seat has been fitted, and should be carried out
in the following sequence:
1.
Adjusting lower leg length and seat depth. See
Adjusting Lower Leg Length, page 8
2.
Adjusting centre of gravity of seat frame. See
Adjusting Centre of Gravity of the Seat, page 8
3.
Checking that castors can move freely.
4.
Checking that wheelchair is stable and will not tip
over. See
Check tipping stability, page 12
.
5.
Repetition of steps 2 to 4, if necessary.
CAUTION!
Risk of injury after tilting of mobility device
caused by blocked castors
– Always check seat depth settings for both
forward and reverse movement. Make sure
that castors can rotate freely and have
not contact to any fixed mobility device
component.
CAUTION!
Risk of tipping over
Any change in the seating position can
negatively influence the stability of the power
wheelchair.
– Always make sure that the wheelchair is
stable and will not tip over, after adjusting
the seating position.
CAUTION!
Any changes to drive program can affect
driving characteristics and tipping stability of
vehicle.
– Changes to drive program may only be carried
out by trained Invacare providers.
– Invacare supplies all mobility devices with a
standard drive program ex-works. Invacare
can only give a warranty for safe vehicle
driving behaviour - especially tipping stability
- for this standard drive program.
CAUTION!
Risk of Crushing to Hands and Feet
The seat is very heavy. Risk of injury to hands
and feet.
– Pay attention to hand and feet.
– Use proper lifting techniques.
4.2 Adjusting Lower Leg Length
Invacare offers a range of legrests which can be adjusted

4.4 Adjusting Centre of Gravity of the
Seat
The centre of gravity of the seat can be adjusted by
mounting the seat frame farther towards the front or the
rear of the chassis.
CAUTION!
The seating system of the mobility device is
delivered ex works with a standard adjustment
of centre of gravity (CoG), which meets 80
– 90 % of user requirements. CoG can be
adjusted individually. However, any change
in this adjustment setting can negatively
influence the stability of the mobility device.
– You must perform an individual risk analysis
every time you change the centre of gravity
of the seating position to ensure the safety
and stability of the mobility device.
