2) With one person operating the pump and another person monitoring the ends
of the hydraulic lines, pump hydraulic fluid through the hydraulic lines using the
pump until a steady stream of hydraulic fluid comes through the ends of both
lines, with no apparent bubbles.
Note:
Fill reservoir as necessary
3) Once air is completely purged from the system, reconnect the hydraulic line to
the HASCO valve.
4) Top off reservoir with hydraulic fluid and reinstall vent plug as shown in Fig. C.
Note:
It should take 5-7 pumps on average to open both valves in series. If more than
10 pumps are required, it is an indication the system is not properly charged. Steps to
purge system (air still in system) will need to be repeated.
Step 10
