2 | Clean up oil drain plug area (1), screwed cap (2), and oil supply plug (3) | Perform an oil change when vehicle is stopped at horizontal level and retarder oil temperature is higher than 60°C. | |
Warning | Risk of injury caused by touching hot retarder and by scalding from hot retarderoil. Risk of injury to skin or eyes caused by retarder oil escaping under high pressure | Do not carry out any work unless retarder is switched off. Wear suitable protective clothing and safety glasses when working on the hot retarder. | |
3 | Remove oil drain plug (1) | Collect the drained oil in a clean recipient. | |
4 | Remove screwed cap (2) carefully | ||
5 | Install adapter (4), with sealing ring, in the hole where screwed cap was (2) | Adapter for the oil change | |

6 | Connect tire gauge (5) to adapter (4) | ||
7 | Apply short air pulses with tire gauge (5) on the retarder | Repeat this action until getting out just oil mist from oil drain plug (1). | |
Inspect | |||
8 | Check the volume of leaked oil in the recipient | The amount of oil should be removed from the 5.4 to 5.6 liters. In case of doubts: | |
| |||
Low oil volume, you should check the transmission oil level and retarder regarding leak (out) and the sealing between transmission and retarder. | |||
High oil volume, you should check the transmission oil level and sealing between transmission and retarder. | |||
9 | Remove tire gauge (5) and adapter (4) | ||
Refill | |||
