1. Fill the fuel store evenly with fuel to approx. 30 cm
above the leaf springs/articulated arms.
2. Start the spring core or horizontal discharge via the
silo filling control unit function.
As the discharge rotates, this causes the leaf
springs/articulated arms to turn.
This process takes about 4 minutes.
3. Once the process has finished and the shut-off
gate valve (if present) is closed, the fuel store can
be filled completely.
