Assistant brake
With this brake, the assistant will get a good control over the wheelchair when traveling upphills and downhills and in
situations where you need the chair to stand still, the assistant can lock the brake and use them as a park brake.
NOTE! The user must not be left alone unattended in a slope with the park brake activated.
If you wish to combine the assistance brakes with armrest for wheelchairs in the S3-series, you´ll need Armrest S3 26”.
This is to avoid conict between the tyres and the sideguard of the armrest:
Armrest S3/U3 26” pair cpl (incl. attachments) art.no. 4401300 piar.
Armrest S3/U3 26” left art.no. 4401301 1pcs
Armrest S3/U3 26” right art.no. 4401302 1pcs
To brake the wheelchair during motion you
clutch the brake handles easily, equally on
both sides to keep the chair in a straight
course. Release the handles to disengage
the brakes.The S3 series uses the pushbar instead
of the push handles. The function of the brake handle is
however the same.
To activate the park brake when standing still,
you clutch the handles hard and keep them
activated while you poke the red levers with
your nger to make them snap into one of the
slots.
To release the park brake you clutch the hand-
les until the red levers spring out and releases
the brakes and the wheelchair is possible roll.
