54 34... Repair instructions for soft top hydraulic system

WARNING: This page is about a different variant/trim than selected.

Definitions of terms

Hydraulic system (untensioned state):	Turn ignition lock to "0" position. Soft top in extreme setting slowly collapses under its own weight. Open the shutoff valve for the emergency opening	Short circuit in the hydraulic system Observe Point 3
Mechanical activation: Emergency operation:	Soft top is opened or closed by hand Always move soft top with aid of a second person	Observe Point 3
Closed system:	All lines are connected
Function check:	Open and close soft top several times (min. 3 times) Check may be performed on the removed soft top. Check fluid level in hydraulic unit; if necessary, top up fluid	Refer to Operating Instructions
Soft top stowed:	Soft top fully open (folded together)	when the soft top is installed, it will be on the storage shelf

When working on hydraulic system, observe the following
- After it has been removed, the soft top must be safely set down or spread out.
  The UNIVERSAL LEVER is absolutely required for this procedure.
- When the hydraulic system is open (unscrewing of lines, topping up of fluid, etc.), always provide sufficient cloths to catch leak-off fluid.
  Also provide an adherent protective cover to cover/protect fittings.
- When opening the hydraulic system, it is absolutely necessary to ensure that no dirt, dust or debris can enter into the hydraulic circuit.
- Disconnect or unscrew feed and return lines if possible at a later stage, when the soft top is stowed and untensioned and/or unscrewed (check fluid, see also Point 3).
- Once the hydraulic system has been opened, first check the fluid level after completing the tasks before carrying out a function test.
- After disconnecting the hydraulic lines from hydraulic components, do not move the soft top if at all possible (fluid can escape from joints).
- Piston rods must not be damaged (e.g. scratches). Even paint mist and welding spots are harmful.
  When working in the vicinity of hydraulic cylinders, cover the cylinders with suitable materials.
- If the hydraulic unit or the lines stay removed for an extended period of time, the bores on the hydraulic unit and the hose connections must be sealed off (observe installation instructions).
Mechanical soft top operation
- Open the shutoff valve for the emergency opening on the hydraulic unit.
- Slightly lower the front side windows and completely lower the rear side windows.
- Soft top EMERGENCY OPERATION .
- In the event of repeated operation, the system fluid is pumped into the supply tank of the hydraulic unit. If hydraulic components are now replaced, there will be too much fluid in the system. This may cause damage to the system in event of operation. (Checking oil level, see Points 4 and 5).
Check oil level
- when the soft top is closed.
- Note BRIEF INSTRUCTIONS .
- Oil level must be within the markings (circle/cross).
- Oil is supplied with the repair kits (e.g. banjo bolts/seals, hoses, cylinders) and is also available separately via BMW/MINI.
Topping up/extracting fluid
- The hydraulic fluid does not have to be changed because the system is filled with life-time fluid. Only the approved hydraulic fluid may be used in the event of leaks.
- Note BRIEF INSTRUCTIONS .
- Remove hydraulic unit without detaching lines.
- Oil is supplied with the repair kits (e.g. banjo bolts/seals, hoses, cylinders) and is also available separately via BMW/MINI.
- Pour in fluid with bottle through filler opening.
- In the event of overfilling, allow oil to escape through filler opening and collect with suitable expansion tank.
Bleeding hydraulic system
- If there is a significant build-up of noise while the soft top is moving, the soft top must be opened and closed several times. This will automatically bleed the hydraulic system in the oil reservoir.
