Cleaning the device
Always keep the device clean. Only clean it with a damp, soft cloth and only use mild deter-
gents for cleaning. Do not use water or large amounts of other liquids as this will cause irre-
parable damage.
Make sure that the cleaning agent that you use does not contain benzene, trichloroethylene,
chloride or ammonia, as these substances attack the plastic housing of the device.
Make sure that all entrances and exits for ventilation are always free of dirt and are not
blocked by foreign objects. Cleaning with a soft brush and compressed air is usually sufficient
to ensure sufficient cleanliness.
Always wear gloves and eye protection when cleaning the device.
Emptying the tank
1. Place the device on a flat, stable surface and start the engine to warm it up. Wait a few
minutes and then turn the engine off again.
2. With the device switched off, carefully unscrew and remove the tank cap.
3. Carefully drain the fuel into a container provided for this purpose.
4. Operate the pump several times to drain the fuel that is still in the lines.
5. Close the tank with the tank cap.
