PRESSURE SETTING PROCEDURES
The following procedures should be used to properly check,
adjust and set the hydraulic system pressures.
The following equipment is required for checking the
hydraulic pressure settings.
• Pressure Gauge
• Three dial gauge 0-345 bar (0-5000 psi)
• Diagnostic quick disconnect - Grove P/N 9999101806
and straight adapter fitting 7447040401
• ORFS reducers as required to attach work port hoses to
the gauge.
NOTE: When checking the directional control valve relief
settings, unless otherwise specified, start with the
engine at idle RPM and move the controller to its
fully stroked position. Then slowly accelerate the
engine to the specified RPM. Read gauge and
make adjustments to specified setting.
When checking the outrigger relief valve setting,
start with the engine at idle RPM and activate and
hold the extend or retract switch. Then slowly
accelerate the engine to the specified RPM. Read
gauge and make adjustment as required.
