I have an older TMZ 34/19 lift.. I seem to have lost hydraulic pressure... Aa of the cylinders have recently been rebuilt...all of the solenoid valves seen to be working...I was useing the lift, cradled the booms, moved it and now it doesn’t want to raise the lower boom...the middle boom is slow and the oil heats up very rapidly... It seems to be bi-passing in the control block on the pump. I have removed the pump ( A gear pump) and cleaned and checked it and the pressure relief, still acts the same...
