Dispose of suspension strut. - OS32.25-P-0122-01N
| Risk of injury to skin or eyes from hydraulic fluid spraying out under pressure. Risk of poisoning from swallowing hydraulic fluid. | Depressurize the hydraulic system completely before starting any work on the system. Wear protective clothing and safety glasses. | AS00.00-Z-0013-01A | |
| Risk of injury caused by drilling gas-filled assemblies or components (noncombustible gases) | Wear safety glasses and a face mask. | AS00.00-Z-0006-01A |
Observe regulations governing disposal of hydraulic fluid.
- By scanning check whether the spring cup abuts the upper stop (arrow) and cut open boot (40e) if necessary.

- Detach hydraulic line (40f) carefully from the suspension strut (due to residual pressure).
- Empty the hydraulic line (40f); to do this, press on the nipple (arrow) of the quick-release coupling and dispose of the hydraulic line (40f).
- Place suspension strut with the hydraulic line connection downwards in a suitable vessel and allow the hydraulic fluid to run out (drainage time at least 5 minutes).

- Drill out suspension strut (40) in the area A through the outer and inner wall (twin-tube damper) and allow gas to escape. (dimension: 40 mm, drill diameter: 5 mm)
- Drill out suspension strut below the spring cup (area B) (max. 13 mm deep, drill diameter: 5 mm) and allow hydraulic fluid to drain out.
