The norm was to use the control levers as if the system was working, with engine running, pull the boom lever to raise position for a few seconds and then push away to lower position, recycle this and when the boom starts to raise, keep the cycle going until you can extend the boom rams full extent, on lowering, pull the rods in as far as they will go, do this a few times and you will bleed the air from the system, do the same for the crowd and dump rams, work the lever for crowd and then dump until the rods fully extend and retract into the cylinders, it may take a little while, if the cylinders still have oil in them, then shouldn't take long at all.
Shouldn't matter what age the machine is, different procedure if the hydraulic pump was replaced or oil drained,
