MANIFOLD
The lift relief valve (SVRV) pressure test should be per-
formed to make sure that the lift c ircuit relief pressure is
correct.
Procedure for LiftRelief Valve(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. Parkmachine ona levelsurfacewiththecuttingunits
loweredandPTOswitchoff.Makesureengineisoff.Ap-
ply the parking brake.
3. Read Precautions For Hydraulic Testing in this sec-
tion.
CAUTION
Before openinghydraulic system, operateall hy-
draulic controls to relieve system pressure and
avoid injury from pressurized hydraulic oil. See
Relieving HydraulicSystemPressure inthe Gen-
eral Information section of this chapter.
