when the free-wheel lever is operated
and fully engaged when the free-wheel
lever is in the drive position.
Driving must be inhibited when the
free-wheel lever is in the free-wheel
position.
If the chair fails this test it must not
be used again until this problem is
corrected.
There must be no flash codes.
Do a test drive on level ground for 2
minutes.
The chair should drive correctly and be
able to climb a 50mm obstacle with no
