I have a linde e15s-02 model lift. Serial number H2X32324S00283.
Unplugged from the charger the other day and the hydraulic pump started immediately when I plugged the battery into the unit with the key in the off position. Turned off main switch and pump stopped but would turn on again as soon as main switch was turned back on. Needed to use the lift for a minute so drove it across the shop and used it with the pump running the entire time. (Maybe 3 minutes). Parked unit to mess with later and when I returned I now have no hydraulic function of any kind. Drive and power steering work correct but main hydraulic pump will not turn on at all.
