Warning

8. Operation

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.
