Hydraulic System, Filling and Bleeding

Hydraulic System, Filling and Bleeding


Oil level must be between "MIN" and "MAX" marking. If oil level is over "MAX" marking, pressure in hydraulic system can become so high that damage occurs.

• The electro-hydraulic convertible top operation is a closed system. Hydraulic oil generally only needs to be topped off after a loss of oil.

• The hydraulic system is filled when the CSC roof is "closed" due to the lift and displacement effects in the hydraulic cylinders.

• New hydraulic pumps are delivered with the bypass bolt open. Close the bypass bolt before filling the hydraulic fluid.

• Always use central hydraulic oil (G 004 000 M2).






Filling

- Remove bracket and hydraulic pump cover.

- Make sure the bypass bolt is closed. Tightening specification: 2 Nm.

- Remove oil filler plug - 4 -.

- Fill central hydraulic oil (G 004 000 M2) until oil level is between "MIN" and "MAX" markings - arrow -.

- Install oil filler plug - 4 -, tightening specification: 2 Nm.

Bleeding

• The hydraulic system is a self-bleeding system. The system is bled after opening and closing the roof 2 times.

- Turn on the ignition.

- Open and close roof 2 to 3 times.

The roof must move smoothly and without jerking.

- Check oil level in oil reservoir - 1 - with roof closed.

- Oil level must be between "MIN" and "MAX" markings - arrow -.

- Correct oil level if necessary.
