MANIFOLD
The lift r elief valve (SVRV) pressure test should be per-
formed to make sure that the lift circuit relief pressure is
correct.
ProcedureforLiftReliefValve(SVRV)Pressure
Test
1. Make sure hydraulic oil is at normal operating tem-
perature by operating the machine under load for
approximately ten (10) minutes.
2. Parkmachineonalevelsurfacewiththecuttingunits
loweredandPTOswitchoff.Makesureengineisoff.Ap-
ply the parking brake.
3. Read Precautions For Hydraulic Testing in this sec-
tion.
CAUTION
Beforeopening hydraulicsystem,operate allhy-
draulic controls to relieve system pressure and
avoid injury from pressurized hydraulic oil. See
RelievingHydraulicSystemPressureintheGen-
eral Information section of this chapter.
