8. Now operate the release lever and move the guide rails until the two rear mounting points are ac-
cessible.
9. Then tighten each of the two rear fastening screws to 25 Nm.
10. Carry out a final functional check of the guide rails and their locking mechanism (see 4.1 Seat
length adjustment (option)).
The fixing of the seat is relevant to safety and must therefore be strictly observed.
The standard screw set for fastening is matched to the optional guide rail set of GREINER GmbH.
When fastening to other guide rails or directly to adapters or brackets, the minimum or maximum
screw-in depth from the surface contour of the six screw-on points on the seat must be observed.
Minimum screw-in depth 20 mm
Maximum screw-in depth 25 mm
The selection of screws with regard to head shape and strength class must be based on the stand-
ard screw set for fastening by GREINER GmbH. When using screws not coated with polyamide, it
is essential to use a suitable liquid screw locking.
