Charge Pressure Test (Using Pressure Gauge) (Machine Serial
Numbers below 316000000)
A charge pressure test should be performed to identify if a worn or damaged
hydrostatic transmission is causing a hydraulic system problem.
Note:
Before conducting charge pressure test, determine counterbalance
pressure setting for the machine; refer to the
Traction Unit Operator’s Manual
.
1. Ensure that the hydraulic fluid is at normal operating temperature.
2. Park machine on a level surface with the cutting deck (or implement) lowered
and PTO switch off. Ensure that the engine is shut off. Set the parking brake
and block the front wheels to prevent machine movement.
3. Read all Warning, Cautions, and precautions listed at the beginning of this
section.
CAUTION
Before opening hydraulic system, operate all hydraulic controls to
relieve system pressure and avoid injury from pressurized hydraulic
fluid.
