Install the counterbalance tank(s) and housings. If the mill has two counterbalance tanks, pressurize each to 1250 psi. If there is just one tank, pressurize it to 1550 psi.
Danger: Each tank is under high pressure. Make sure to wear appropriate personal protection equipment. Installation should only be done by trained personnel. Refer to the Haas Service Manual for complete instructions on installing the counterbalance tank(s) before attempting this procedure.
Note: There may be (1) or (2) counterbalance tank/housing assemblies. If there are two assemblies, install the housings and tanks for both.
Note: The counterbalance charge/discharge kit is P/N 35-4050A.
