Draining water from your filter.

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 the following:

• Flathead screwdriver
• Gloves
• Suitable bowl to collect water
