Remove
Important. During the whole operation, it is crucial to carry the work out in a clean environment. Dirt around the metering device is to be avoided. Even small contaminations, which can not be seen with the naked eye, can lead to severe problems affecting engine performance. Particles sized 0.3 mm can already prove to be critical. Do not wear gloves. Do not install a metering device that had been previously dropped. Remove battery terminal after fault finding. Before replacing the metering device, wait a few minutes to avoid the system self-starting.
