Danger! | Risk of accident by the involuntary movement with the engine running. | Protect the vehicle against involuntary moving. | |
Risk of injury by crushing or burn in the contact during the start procedure with the engine running. | Use work clothes that are closed and fit. Do not touch heated or moving parts. | ||
5 | Start the engine and completely charge the pneumatic system with idling rotation | Pay attention to the pressure enough during the tests. If necessary, supply the system again with compressed air. | |
6 | Shut down the engine | ||
7 | Test the pressure of the coupling terminal to the accumulator (35.02) | ||
8 | Perform the pressure test with the parking brake | ||
9 | Perform the pressure test with the service brake | The towing control vale for the 2-circuit brake (18.05) is equipped with a feed device. In the supplying status, it is regulated to a supply of approx. 0 bar. Adjustment range from 0 to 0.6 bar of feed. If it is desirable a different supply adjusted, adjust the semi-towing control valve: | |
Brand Grau: - remove the muffler (4) in the 2-circuit brake control valve (18.05) from the towing. - turn the adjustment bolt with internal hex with Allen wrench (SW 6, length > 140 mm). | |||
Brand Knorr: - remove the threaded plug in the muffler (4). - turn the adjustment bolt with internal hex with Allen wrench (SW 6, length > 140 mm). | |||
Rotation direction to the right increases the supply. Rotation direction to the left decreases the supply. | |||
| |||
10 | Remove the testing case | ||
11 | Remove the coupling terminal for pressure test (5) | ||
12 | Remove the intermediate part (6) |
