When you need to climb spiral stairs, the single step mode
is particularly useful. As stated in chapter 4.6, there it is
indispensable to advance the scalamobil’s outer wheels to
the edge of the following step. When you activate the single
step switch, you automatically prevent an erroneous initiation
of the climbing cycle before the scalamobil’s wheels are all
the way at the edge. Therefore, the climbing and descending
becomes even safer for both the person operating the
scalamobil and the person being transported.
For persons unskilled in operating the scalamobil, we
recommend to activate the single step switch also for
climbing regular stairs.
If you continuously push the driving switch
[2], the wheels complete one rotation. As soon
as you release the driving switch [2] the wheels
come to a standstill, also when the single step is
activated.

Special Soft Step Function
The Soft Step feature is integrated into the scalamobil
control program and activated in the factory settings. If
desired, your
representative can deactivate the
function.
When Soft Step is activated, and depending on the selected
driving speed, the rotation speed of the scalamobil motor
decreases just before the wheels come to rest on a step.
Once this has been surmounted, the motor increases its
speed of rotation again until just before the next step is
reached. This movement procedure produces a softer landing
of the scalamobil wheels on the steps of the staircase,
resulting in the wheelchair occupant noticing a much gentler
course of movement.

Operation on Winding Stairs
In principle the operation of the scalamobil climbing or
descending winding stairs follows the analogous steps
described in chapter 4.2 and 4.3. Also the same safety
instructions apply. However, we would like to call your
attention to the following particular characteristics, since
the inside wheels cross a shorter distance than the outside
wheels.
