I have the TA-55 on my tractor, which looks similar to the TA-111. From my book, here are the "official" instructions.
A)- Find a level place to set the loader. (I'm lucky enough to have a concrete slab that works great) Place the bucket on the ground. (I tilt mine forward a little so water won't accumulate in it.) Pull the L-pins (on the front of the tractor) and back away from the loader. Extend the lift cylinders to set the front wrap on the ground and release the shoes from the cross tube.
B)- Disconnect the hoses and complete the oil circuit by connecting the manifold hoses together or switching the flow control.
