    sounds like your hydraulic pumps are coming on stroke when they should not be. 1.can you check pressures to find out which pump and how much pressure it's building. 2. are any functions trying to move when you start the machine? 3. after it starts does the rest of the machine function normally? 4. has anything been recently repaired or replaced like hoses or wiring? 5. are both batteries good and what is the condition of the cables and starter
