Started my ct332 yesterday at 12 degrees tracks were packed with mud and frozen, let it warm for a few minutes but apparently not long enough. Moved boom up and down a couple times and it was jumpy like when air is in a line. Let it run at high speed for 10 minutes came back and no hydraulics at all anywhere. Opened operator station up and on right side there is hydraulic fluid all over. Also in the bottom of the machine. Cant find a leaking hose or fitting. In these circumstances where do I start looking? Is there a part that usually gets damaged First in cold weather operation?
