METHOD FOR CHECKING FUNCTION OF PPC ACCUMULATOR
For handling of the accumulator, see “HANDLE ACCUMULATOR AND GAS SPRING (2-40)”.
When you cannot restart the stopped engine while the work equipment is raised, you can use, as urgent meas-
ures, the oil pressure stored in the accumulator to actuate the valve, thereby, lower the work equipment to the
ground.
