If the position of the rear wheel is changed the brakes
need to be adjusted.
The correct functioning of the brake also depends on
the correct rear tyre pressure being maintained.
(see chapter 2.6
"Tyre pressure").
The parking brakes are designed to keep the
wheelchair in position when stationary. For safety
reasons we do not recommend using the parking
brakes for braking while the wheelchair is in
motion.

remove the bolt "B" and use another slot.
