1) Loosen all mounting screws (countersunk head screws) between the seat plate and seat plate supports (see
fig. 12, item 1).

6.7 Adjusting the Seat Height

CAUTION
Installation without an assistant
Pinching on components, damage to the seat
► Always get help from an assistant to adjust the seat height.
The seat height can be modified/adapted if necessary – e.g. to obtain more ground clearance for the footplates
because of long lower legs.
1) Remove the locking mechanism linkage (see Page 15).
2) Loosen 2 x Allen head screws on both sides between the seat frame and main frame (see fig. 14, item 1). Have
the assistant hold the seat during this process.
3) Select the new seat height. Move the seat up or down in the adapter tube in order to do so.
INFORMATION: Note the allowable seat height settings (see the chapter "Technical Data"). Please
note that excessive seat height can lead to overall system instability with large/heavy seating shells.
4) Firmly retighten all Allen head screws to a torque of 10 Nm.
5) Adjust/install the locking mechanism linkage (see Page 15).
