HYDRAULIC SYSTEM DESCRIPTION•The following is a detailed description ofthe hydraulic system used on the CONDOR® modelV14331XL, VI 833IXL scissor, and how it designed to operate. To assist in understanding the system,this description should be used in conjunction with the hydraulic schematics found at the end of thissection.GENERALThe hydraulic system on the CONDOR® model VI 4331XL, V1833IXL consists primarily of asingle manifold assembly, used to control all the hydraulic functions through the use of hydrauliccylinders and motors. The system is electric over hydraulic, meaning that the hydraulic valve assemblyis activated by electrical signals from the function controls. The system is also of the open-center valvetype, meaning that the hydraulic fluid circulates back to the tank when the pump is running and nofunctions are being operated. All lift and drive functions can be performed from the platform console,while ONL Y lift functions are available from the lower control console.HYDRAULIC TANKThe hydraulic tank is an ItL It shapedweldment having a fluid capacity of 7 US gallons.The main portion of the tank is locatedbetween the batteries in the belly pan, with thesmaller portion extending outward to the rightside ofthe unit (See FIG. 1) next to the hydraulicpump. A filler neck and cap, and a sight glass areprovided at the extended section of the tank forchecking and maintaining the fluid level. Filtrationof the hydraulic oil is provided through a 10micron spin-on return filter, and a 100 mesh, 10GPM, tank-mounted strainer. The filter, andstrainer are located at the end of the tank, justbehind the pump.BallValveFiller CapFIG. 1NOTE: Only check the tank fluid level when the unit is in its stowed position to ensure the level willbe at its highest. The hydraulic fluid used is Shell Tellus T -32 and only this fluid, or its equivalent shouldbe used.DO NOT MIX HYDRAULIC FLUIDS.MANUAL 92370-002November 1997
