Danger | Risk of explosion due to escaping combustible gas or overheating of gas cylinders.Risk of injury caused by burns to skin and eyes. Risk of frostbite to body parts caused by escaping gas and by touching components near the valves when emptying gas cylinders. Risk of poisoning or suffocation caused by inhaling gas. | Remove any sources of ignition. | |
Warning | Risk of injury. Skin or eye injuries may result when handling hot or glowing objects. | Wear protective gloves, protective clothing and safety glasses, if necessary. | |
Warning | Risk of accident from vehicle starting off by itself when engine running. Risk of injury (bruises and burns) resulting from working on the engine while it is being started or when it is running. | Secure vehicle to prevent it from starting off by itself. Wear closed and snug-fitting work clothes. Do not touch hot or rotating parts. | |

1 | Start engine and warm up to operating temperature. | See information from body manufacturer. | |
2 | Switch off engine. | ||
3 | Release bracket of the compressed-air line (2.1) from the timing case. | ||
4 | Remove air intake line (0.1) at compressor (1). | ||
5 | Remove control line at compressor (1). | Only if one compressor (1) with control line is installed. | |
As a result, it is ensured that the compressor (1) is then also in the delivery phase if the output of the compressor (1) is impaired by another defect, e.g. on the pressure regulator. | |||
6 | Remove compressed-air line (2.1) at fitting (2). | ||
7 | Check test compressed-air reservoir (3) for proper working condition. | ||
| 000 588 00 21 00 Leak tester | ||
If necessary, drain condensation contained in the test compressed-air reservoir (3). | |||
8 | Attach test compressed-air reservoir (3) with test compressed-air hose (2.2) to fitting (2). | ||
9 | Attach test kit (9) with measuring hose (8) to test compressed-air reservoir (3). | Test kit | |
| Check | ||
10 | Perform filling time test. | To test the filling time, start the engine and the time recording device at the same time. | |
Filling time test (with test compressed air reservoir and test kit) | |||
If the permissible filling time is exceeded, | |||
| |||
replace cylinder head of the compressor (1). | |||
11 | Perform pressure drop measurement. | The factor measured is the pressure drop over the seals in the compressor (1) in a prescribed period of time. | |
Pressure drop measurement | |||
If the pressure drop is too high, | |||
| |||
replace cylinder head of the compressor (1). | |||
12 | Depressurize test compressed-air reservoir (3) on the stopcock (7). | ||
13 | Remove test kit (9) with measuring hose (8) from the test compressed-air reservoir (3). | ||
14 | Remove test compressed-air reservoir (3) with test compressed-air hose (2.2) from the fitting (2). | ||
15 | Check compressed-air line (2.1) for carbonization. | If carbonization is present: | |
| |||
in addition, check compressed-air lines between the compressor (1), compressed-air drier, and four-circuit protection valve and electronic air-processing unit (EAPU); replace carbonized parts if necessary. | |||
| Install | ||
16 | Attach air intake line (0.1) to the compressor (1). | ||
17 | Install compressed-air line (2.1) at fitting (2). | Union nut, compressed air line to fitting | |
18 | Attach bracket of the compressed-air line (2.1) to the timing case. | ||
19 | Install control line at compressor (1). | Only if one compressor (1) with control line is installed. | |
20 | Start engine and run at idle speed. | See information from body manufacturer. | |
21 | Check line interfaces at compressor (1) for leaks | Perform visual inspection. | |
22 | Switch off engine. | ||
23 | Print out questionnaire and fully fill in. | Only if a new compressor (1) was installed and if the cost acceptance for this is applied for as part of the warranty and goodwill. | |
| Questionnaire on compressor delivery rate and oil ejection test, form | ||
For a warranty and goodwill claim, submit the completed questionnaire together with the removed compressor (1). |
