Maintenance Manual
Main Relief Valve
Pressure Adjustment
(Vane Pump Systems)
Note:Make sure to perform the
“Dump Valve Pressure
Adjustment Procedure” on
page 100 prior to performing
any adjustment on the main
relief valve.
It is recommended to check the
pressure setting once every month in
order to prevent damage to the
equipment and to make sure it
operates as efficiently as posssible.
(i.e: keeping a good packing capacity).
If the pressure is not at the
recommended setting, both the dump
valve and the main relief valve have to
be readjusted. Refer to the pressure
adjustment table for proper settings
according to the type of chassis and
packer cylinder size.
Each of the hydraulic valve sections
operates at a different pressure
setting. Some are using a fixed work
port relief (Figure 164. “Main hydraulic
valve”) and some others use system
pressure. For details, refer to the
hydraulic system schematics included
in the operator manual pocket located
in the cab.
