Draining water
Both the grey and blue filters will isolate water collected from fuel. They each have sensors which trigger an alert when they reach a certain level and require the water to be drained. This can however be done regularly before the alert is triggered to avoid the machine stopping.
You will need:
- Flathead screwdriver
- Gloves
- Suitable bowl to collect water
