Accumulator Charge
The precharge should be checked every 6 months.
The accumulator must be charged by a qualified hydraulic service
facility to a nitrogen precharge of 500 psi.
An approximate amount of charge can be noted on the system
pressure gauge when the HPU is turned on. When the HPU is
turned on, the gauge will jump to a pressure before continuing
to build pressure. The initial jump in pressure will indicate the
approximate pressure of the precharge.
NOTICE: The precharge should be checked/maintained by a
qualified hydraulics repair tech.
