6.8 Adjusting the Locking Pedal
CAUTION
Incorrect setting of the locking mechanism linkage
Falling from the seating shell, malfunction, damage to/destruction of the release mechanism
►
Adjust the length of the locking mechanism linkage so that the locking pins fully engage in the locking plate in
the seat frame and the locking mechanism is in the front position. Only then is the support of the seat assured
with extreme settings or when driving over rough surfaces.
►
Secure the screw connections of the locking mechanism linkage so it is free of tension, without pulling or
pushing.
Changing the seat height (see Page 14) or the positions of the wheel adapters (see Page 22) requires changing
the length of the locking mechanism linkage.
1) Loosen 2 x Allen head screws on the locking mechanism linkage (see fig. 15, item 1).
2) Change the seat height or the position of the wheel adapters.
3) Prior to assembly, determine the correct length of the locking mechanism linkage:
→
The locking pedal must be in the neutral position (see fig. 15: pedal is up against the stop at the top).
→
The locking pins must be fully extended (see fig. 16, item 1).
→
The locking mechanism must be in the forward position (neutral position).
4) Secure the screw connections of the locking mechanism linkage so it is free of tension (without pushing or
pulling, straight in one plane). Use suitable slotted holes in order to do so.
5) Tighten the Allen head screws to a torque of
8 Nm
.
Testing the locking mechanism
Carry out a functional test after assembly is complete. Note the following:
•
The locking pins must fully engage in the locking plate. Reference point: the locking pins protrude slightly from
the locking plate (see fig. 16, item 1).
•
It must be possible to depress the locking pedal to the stop without a lot of force. The mechanism unlocks
completely in this process. Reference point: the locking pins are recessed 1 – 2 mm in the plastic locking
mechanism housing.
