Gear changing

The gearbox has three positions: direct drive (1:1), low gear,
and low gear + hill hold.
• Direct drive (1:1) – As in a regular wheel where the hand rim
rotates at the same speed as the wheel
• Low gear - The hand rim rotates faster than the wheel, reducing
the effort required to push the chair by about 40%.
• Low gear + hill hold - In addition to the lower gear, the wheels are
locked from rolling backwards. Note that this greatly increases the
risk of tipping backwards, since the user cannot control the balance
of the wheelchair in the normal way.
To select low gear, move the shift lever forward as far as it will go
(Figure 8.1) To switch back to direct drive (1:1), move the shift lever
backward until it reaches its vertical position (Figure 8.2). To switch
to reverse lock (hill-holder) mode, move the shift lever backward
(Figure 8.3). To switch back to 1: 1, push the shift lever forward to its
vertical position (Figure 8.4)

Risk of tipping backwards increases when the gear is in
reverse lock/ hill-holder mode. Tipping protection must
be used.
• It is possible to shift gears when in stationary position but it is
easier and more convenient to shift when in motion.
• The hill-hold function shall be used regularly, at least once a
week to ensure full functionality.
