2.
Determine the centreline of the vehicle and
put a slat on the superstructure roof
protruding into the cab direction.
3.
Put another slat (as a tangent) onto the
outer roof spoiler edge (P) pointing into the
direction of the superstructure.
4.
Both slats should cross at half the distance
(

the start of the superstructure.
The roof spoiler height can be adjusted
using adjusting mechanism (B). For the roof
spoiler adjusting range, see main group
