5.10.1 Manually using spindle
The seat angle is adjusted by means of a spindle, which is
to be found at the front underneath the seat frame.
When adjusting the seat angle it should be ensured that at
least 1 cm of the threaded bolt always remains inside the
spindle and is not completely unscrewed from the spindle.
It is easier to adjust the angle of the seat when there
is nobody sitting in the wheelchair.
The figure shows the position of the spindle (1) for manual
seat angle adjustment.
