TM 9-2320-366-34-1 2-1037 Left and right outriggers are tested the same way. Left outrigger is shown. NOTE Fuel and oil are slippery and can cause falls. Wipe up spilled fuel or oil with rags. Failure to comply may result in injury to personnel. Wear approved eye protection when performing pressure checks. Failure to comply may result in oil getting into eyes. If oil contacts eyes, seek medical attention immediately. Drop hydraulic pressure to zero before disconnecting any hydraulic line. Failure to comply may result in injury to personnel. WARNING Check position of left outrigger to verify that it is held in the stowed position. If left outrigger will not remain stowed over a period of time, holding valve is faulty. CONTROL VALVE FLOW TEST (13)  Position PTO switch to off (TM         9-2320-366-10-1). (14)  Shut down engine (TM 9-2320-366-10-1). (15)  Disconnect hydraulic tester, hoses and         adapters. (16)  Connect hose to port B.     (1)  Place drain pan under vehicle.   (2)  Disconnect hose from port B of left outrigger         jack cylinder.   (3)  Connect hydraulic tester between hose and         port B with test hoses and adapters.   (4)  Start engine (TM 9-2320-366-10-1).   (5)  Position PTO switch to on (TM         9-2320-366-10-1).   (6)  Position MHC power switch to on         (TM 9-2320-366-10-1).   (7)  Increase engine rpm to 1250-1450 rpm (TM         9-2320-366-10-1).   (8)  Lower left outrigger (TM 9-2320-366-10-1).   (9)  During lowering, observe reading of 4 gpm (15         lpm) at 3000-3100 psi (20685-21375 kPa). (10)  If flow reading is not 4 gpm (15 lpm) and         pressure is not between 3000-3100 psi (20685-         21375 kPa), replace control valve in eight bank         valve assembly (para 16-59). (11)  Raise outrigger (TM 9-2320-366-10-1). (12)  Position MHC power to off (TM         9-2320-366-10-1).
