Use the axle hut or QR to hold the remover on tightly, then put it in the vise. Turn the wheel to the left to remove, but the moment the freewheel breaks loose, stop and loosen the nut or skewer, otherwise as the freewheel moves out it'll damage the axle or skewer.
I leave the axle nut about 1/8 turn loose, maybe not even that much. That's enough to hold the freewheel remover in place, but loose enough to give the freewheel room to loosen. If you don't have a solid bench vise, I've removed a lot of freewheels using a BIG (15") Crescent wrench. Hold the wheel vertically in front of you and push down on both sides at the same time.
If your freewheel really only has about 150 miles on it, it'll probably come loose fairly easily.
