MANIFOLD
The gear pump (P4) flow test should be performed to
make sure that the cutting unit lift circuit has adequate
hydraulic flow.
Procedure for Gear Pump (P4) Flow
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.
