SPRUNG mode provides for a smooth ride up to 30 mph (48km/h) and is used for over the road marches and

parking of the vehicle. Hydraulic pressure is supplied to the front actuators through line 9.

WARNING

S

High oil pressure is present in the M9 hydraulic system. Do not disconnect any

hydraulic system component unless hydraulic system pressure has been relieved.

After hydraulic system pressure has been relieved, wait at least 4 minutes before

disconnecting any hose or fitting. Ensure each of the hydraulic control levers is

moved several times through all positions and the hydraulic tank dipstick is slowly

loosened to relieve pressure. Failure to comply may result in severe injury or

death to personnel.

S

Transmission shifting lines are pressurized. Do not disconnect lines, fittings, or

accumulator unless transmission shift control valve pressure has been relieved.

Discharge transmission shift accumulator by moving shift control lever through all

forward and reverse ranges several times, with engine off. Failure to comply may

result in severe injury to personnel.

NOTE

Use these procedures to troubleshoot either left or right front of vehicle.
