If I was you, I would stop running it right now. First thing you should do is check the coolng fan speed. I have a feeling the fan is turning too slow. So to do that, you and a buddy should start the thing and check how fast the fan is spinning. Should be around the speed of an electric fan of a car or just slower. If its turning too slow, you'll need to buy a pressure guage, hose, and a quick connect setup that threads into the housing of the hydrostatic pump, and check your "charge pressure". Charge pressure is very important, if its too low you will destroy your hydrostatic pump, and that is a $3000 dollar kiss you don't want. Charge pressure should be 450PSI give or take 20PSI. The charge pump controls all work tool movement, cooling fan, and oil supply to the hydrostatic pump. The hydrostatic pump controls the drive function of the machine. The drive pressure is 5600PSI, so be careful not to test the wrong port. If you don't have a service manual now is a good time. Best $500 bucks I ever spent. Let us know what you found and I'll try to post some pictures of my pressure tap locations. Oh, and don't buy a guage that will read 6000PSI to test a 450 pound port. A guage isn't accurate until 60% of its capacity.</p></blockquote><p></p>
