I just bought a 2003 Series II skid steer. On the parking brake switch it stays red all the time including when the switch is disengaged. It appears to disengage because I can tell a difference when trying to move and also the parking light (red dot) goes off. Is the red light (parking brake swich) on all the time normal? Also I have noticed sometimes at lower RPM's that when tilting the bucket I kind of here a screatching noise. Is this normal? It appears to be coming from the cylinders. Anything to watch for on these machines? It has 1900 hrs on it and appears to have had a very good home. There is tons of these in the area and everyone seems to love them.
