The owner manual says you loosen the gearbox strap bolt, then loosen the six retaining bolts that hold the idler sprocket bracket from underneath the chassis, and slide the idler sprocket as required. There should be 5 mm of chain drop mid-span when you've done it. The picture hasn't reproduced well, so I don't feel all that well-informed, but it doesn't sound complicated.
