I don't think your winch has a power out mode. Most of the skidders did not.
If I am wrong about this please send me your serial number and I will dig into the model you have. I have some information on winches attached. If you winch is different include the winch model and serial number with your reply. It is stamped on the winch but, I am not sure of the exact location.
518 winch operation.
Here is more on the later models, these are usually CAT made winches and were very common in my area.
I would guess your brake release is not working correctly. Check this info and see if it won't help understand this unit.
Here is the testing book also.
Let me know if this is not correct, the serial number may help if it is not. I will try to find other information.
Here is info for the older Gearmatic winch, it has more cast iron in its housing and is rounder shaped.

Either way you should be covered.
Glad to hear that, thanks for the reply.
Let me know if I can help you again.
I did like the simple design of the 518, it only has some tough spots to work on. The rest of the machine is solid as long as it doesn't use wide tires.
Important note: Replace the u-joints every year in the center section or it will fail and damage the transmission housing.
