Invacare Bora XTR Series Service Manual page 11

CAUTION!
Any changes to the drive program can affect the
driving characteristics and the tipping stability of
the mobility device.
– Changes to the drive program may only be carried out
by trained Invacare® specialist dealers.
– Invacare® supplies all mobility devices with a standard
drive program ex-works. Invacare® can only give a
warranty for safe driving behaviour - especially tipping
stability - for this standard drive program.
Tipping stability check
1. Set the following angle on the wheelchair:
•
Recline 30°
•
Seat tilt max.
2. Allow user to down in mobility device in a sitting position that
is typical for them.
1528338-P
3. Drive front wheels of mobility device onto a step about 100 mm
high. This can be done using a ramp, for example (illustration B).
4. Make sure that front wheels are pointed backwards compared to
direction of travel.
5. Attach a reference weight of 8 kg to the push bar (illustration B).
6. Verify that mobility device is at most in a balanced or "floating"
condition in this position. This means that front wheels can
slightly lose contact with ground, but chair must not tip back
onto its anti-tipper wheels. If mobility device does not fall back
onto its anti-tipper wheels, tipping stability is OK. If mobility
device falls back onto its anti-tipper wheels, you must either:
•
Shift center of gravity far enough forward that chair does
not fall onto anti-tipper wheels or
•
Install adaptor
7. Repeat steps described above after each modification to verify
tipping stability.
