Customer Question

I have an older skyjack scissor lift model #sjiii3220. The lift will steer but not move forward or in reverse and it will not go up not even with the switch in the hyd. door. I have checked to see if the solenoids are firing and they are. When I try to raise it you can hear the pump pull down but again nothing happens. At first I thought maybe the level switch was out of wack, it has a green and red light that are both lit and when I move it slightly a orange light also comes on(I'm not sure what all the lights mean). Any ideas would be greatly appreciated. Thank You.
