HUSK-E usage instructions
Please note that, after a large adjustment
to the chain pedal bearing position, the lines
and the cable lengths must be adjusted.
20.2.4 Crank length and grip width
The crank length can be chosen from different
lengths individually to suit the length of the
arms and mobility of the user. Different widths
of pedal bearing shafts and spacers between
the pedal cranks and the rotary axles of the
hand grips are available to adjust the grip
width.
If you want to make a change to the crank
length or grip width, please contact your
rehabilitation specialist dealer or PRO ACTIV.

20.3 Grips
The grips must be held firmly with both hands
whilst driving and always held so that the
cables and lines are oriented upwards.
Figure 22: Correct grip hold
both hands while driving, braking, and
manoeuvring. If a driving situation requires you
to take one hand off the crank handle, make
sure the speed has been reduced to the
minimum possible beforehand.
20.4 Gear shift
20.4.1 Dérailleur
For the chain shift, shifting procedures can
only occur while the crank is moving. Changing
the gear with the cranks stationary is not
possible. In general, the torque applied to the
cranks should be reduced briefly while
changing the gear so that the gear change can
happen more quickly.
Hand grip
The gear change controls are normally
rotary axle
designed so that they can be operated using
thumb / index finger shift control or
optionally using chin operation. With the
cassette at the bottom, switching to the next
Pedal
largest sprocket means a lower or easier gear
crank
and to the next smallest sprocket a larger or
more difficult gear.
If you have installed an electrical Di2 gear shift
onto your product, you can shift up or down by
pressing the up or down arrows.
