Pressure Setting Procedures - Manitowoc RT9150E Service Maintenance Manual

HYDRAULIC SYSTEM

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.
• Three dial pressure gauge, 0-5000 psi
• Pressure check diagnostic quick disconnect - Grove P/N
9999101806 and straight adapter fitting 7447040401
• ORFS reducers as required to attach work port hoses to
the gauge.

RT9150E SERVICE MANUAL
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.
The number after G (gauge port) corresponds to
the gauge port number on the hydraulic system
schematic (G1 through G3).
All valve settings can be obtained by adjusting the
valve "in" to increase or "out" to decrease the
pressure accordingly.
