Damper Adjustment
Protects the spine of the driver, as the damper absorbs the vertical shocks
and vibrations. By adjusting the damper, the suspension characteristics of the
seat can be optimally adapted to every roadway and every driver.
Lever up: Soft suspension, minimum damper force.
For at roads.
Lever down: Hard suspension, maximum damper force.
For rough roads.
Damper adjustment must be adapted in case of changing road conditions.
The damper shall be adjusted stiff enough, so that in rough road conditions the
driver’s feet never loose contact with the pedals.
Don’t adjust the damper so soft that on rough roads the seat can knock through.
Take care for a sufcient distance to the cabin´s ceiling.
In general heavy drivers don`t have to use a soft adjusted damper.
Lower Lumbar Support
Promotes an upright posture and prevents fatigue by tuning the backrest con-
tour. This modifable shape of the lower backrest adjusts the position of the
driver’s pelvis by turning the pelvis forward and upright.
● Relaxation of muscles
● Load relief in the spine
● Increase in comfort
Press button forwards for blowing the air-chamber respectively backwards for
exhausting for turning the pelvis forward and upright. This turns your spine into
its ideal double S-shape.
The lumbar support prevents driving in a slouched or hunched position and
prevents driving in a hollow-back position.
It is recommended to change the sitting position from time to time.
Upper Lumbar Support
Promotes an upright posture and prevents fatigue by tuning the backrest con-
tour. This modifable shape of the lower backrest compensates driver’s
hollow back.
● Relaxation of muscles
● Load relief in the spine
● Increase in comfort
Press button forwards for blowing the air-chamber respectively backwards for
exhausting to match the shape of the lower backrest contour in order to sup-
port fully the driver’s back.
The lumbar support prevents driving in a slouched, hunched or in a hollow-
back position.
Please note that your whole back must touch the backrest from the buttocks
to the shoulders. Therefore the lower lumbar support shall be adjusted rstly.
It is recommended to change the sitting position from time to time.
