60 kg load to the seat suspension for 24
hours. The lowering within this time must
not exceed 15 mm.
1 Remove the upper seat part at the seat
suspension and put it aside (see
Chapter 3.1).
Notes:
● Cable ties at cable harness for upper
seat part need not be removed and the
electrical connections need not be
disconnected.

for the upper seat part when putting it
aside.

suspension part (see Chapter 3.3) and
press it down.
