700- Pneumatic Gearshift and Pedals

700 - 1 Pedals

The pedal box has a large adjustment range in order to achieve the best possible

ergonomics for drivers of different stature. The individual possibilities are

described below in details.

700 - 1.1 Longitudinal Adjustment Pedal Unit

The seat is bolted firmly to the chassis. The pedal unit is mounted to a sledge

adjustable longitudinally. The adjustment range is 60 mm in 20 mm steps.

Image 20: Rails with Ratchet and Detent Mechanism

To move the pedal unit it must be released. A pneumatic valve as button is

located in the centre console. It activates a small pneumatic cylinder that

disengages the pedal unit.

Compressor

The compressed air is taken from the compressor for the gearshift. If the car is

not used for a long time, the compressed air reservoir will be empty. In this

case, the MAIN switch in the centre console must be switch on. The compressor

will start to run. As soon as it switches off automatically, there is sufficient

pressure stored in the reservoir to disengage the pedal unit.

The pneumatic valve takes the form of a button in the centre console. This

means that as long as the button is depressed the pedal unit disengages.

A gas pressure cylinder moves the sledge automatically to the rear towards the

driver, who can then move the sledge forwards by pushing the cover below the

throttle pedal plate with the heel of their right foot.

Attention

Only push the pedal unit forward using the area marked in the image below.

Pushing in other positions (e.g. on the left footrest or the brake pedal) increase

the force required and can cause the unit to jam!

Image 22: Push Surface on the Pedal Unit Cover

When the button is released, two independent springs push the lock into the

detents. If the lock is between two detents, the next closest position can be

selected by releasing or pushing with the right heel. The lock then clicks audibly

into position and the pedal unit is locked in position. Pressing with heel again

checks whether the unit is locked safely and thus ready for use.

Procedure to Adjust the Longitudinal Position of the Sledge

-

Ensure that the pneumatic reservoir is charged with sufficient pressure, or

switch on the MAIN switch and wait until the compressor switches off

-

Press the button valve in the centre console

Move the sledge to the desired position by pushing below the throttle

pedal plate with the heel of the right foot

-

Release the button valve in the centre console

The next closest locking position is achieved by pushing the sledge with

the right heel or by releasing the sledge

-

Check that the sledge is securely locked by pushing with the feet

700 - 1.2 Throttle Pedal

The following adjustments can be made to the throttle pedal:

-

Lateral position of the pedal plate

Spring preload

Damping

a) Lateral Position of Pedal Plate

There are two positions. The pedal in the left hand image shows the standard

position. The plate can be moved 10 mm to the right to create more space

between the throttle and brake pedal.

b) Spring Preload

A long compression spring is installed in the throttle pedal. At one end, a

plunger pushes the pedal against the foot, at the other end there is a threaded

stud with a nut.

By turning the nut (16 mm AF spanner), the threaded stud is moved and the

spring preload changed. The basic setting is shown in the following image. The

pin in the slot shows the actual setting. The pin at the top means the minimum

spring preload is set. The pin at the bottom means the maximum spring preload

is set.

c) Damping

The damper of the throttle pedal is located below the cover on the left of the

gas spring used for moving the sledge.

Image 26: Pedal Assembly – Throttle Pedal Damper

The damping is adjustable. The standard setting is completely soft. Changing

the damping is made by rotating the cylinder relative to the piston rod. When

fitted, the damping is adjusted as follows:

-

Remove the pedal unit cover (4 bolts)

Disconnect the spherical bearing of the gas spring used to adjust the

sledge

-

Remove the rear mounting bolt of the damper

-

Swing the damper to the right (see Image 27)

Rotate the damper clockwise --> stiffer damping

Rotate the damper anticlockwise --> softer damping

While rotating pull lightly on the cylinder so that the adjustment gears engage

in the piston.

When the resistance increases noticeable while rotating stop the adjustment!

Attention

Do not use force to rotate otherwise the adjuster segment in the damper can be

damaged!

Attention

The driver’s foot can get tired if the damper is set too hard.

-

Remount the damper using the bolt

To check the pedal force required press the pedal at different speeds to

simulate throttle application

-

Remount the gas spring used to adjust the sledge position

Refit the pedal unit cover (4 bolts)

Sit in the driver’s seat and check the force required to press the throttle

pedal. Do this at different speeds to simulate throttle application.

700 - 1.3 Brake Pedal

The following adjustments can be made to the brake pedal:

-

X Position (longitudinal offset between brake and throttle pedals)

Y Position (distance to throttle pedal and to left foot rest)

Z Position and angle (height and angle of pedal plate)

a) X Position

In the standard position, the brake pedal plate is on the same plane as the left

footrest and compared to the throttle pedal plate 10 mm closer to the driver. If

required, the brake pedal can be moved another 10 mm closer to the driver. A

second row of holes is provided in the brake pedal plate for this purpose.

Attention

The distance between the pedal plate and the driver should not be adjusted on

the brake master cylinder, otherwise the bell crank geometry changes and the

system can stick in the depressed position!

b) Y Position

To increase the distance to the left footrest or the throttle pedal plate to the

right, the brake pedal plate can be turned through 180°.

c) Z Position and Angle

The brake pedal plate can be adjusted in both height and angle for drivers with

particularly large or small feet.
