Hydro-pneumatic accumulators
Hydro-pneumatic accumulators do not require any
particular maintenance.
Regularly check the tightness of the accumulator fixing
bolts and that no oil has leaked from hydraulic circuit (a
small oil leak can change settings) (1).
To depressurize the circuit:
- Place the machine in parking position.
- Open valves (1) using 18 mm box spanner.
- Decrease pressure until gauges indicate 0 bar (0 psi).
- Shut-off lock valves.
-
Before any work is carried out on a hydraulic
circuit with hydro-pneumatic accumulator,
depressurize the circuit.
It is strictly forbidden to weld, grind or drill
onto a hydro-pneumatic accumulator.
Pressurize the hydraulic circuit before
activating any other hydraulic function of the
machine.
