NOTE: The ports on the Ultra Sonic Boom System
boom lift control manifold are marked for easy identifica-
tion of components. Example: P is the pump supply con-
nection port and S2 is the location for solenoid valve S2.
See Figure 25 to identify the function of the hydraulic
lines and cartridge valves at each manifold port.
NOTE: The boom lift control manifold includes two (2)
zero leak plugs. These plugs have a tapered sealing
surface on the plug head that is designed to resist vibra-
tion induced plug loosening. The zero leak plugs also
have an O−ring as a secondary seal. If zero leak plug re-
moval is necessary, lightly rap the plug head using a
punch and hammer before using a wrench to remove
the plug: the impact will allow plug removal with less
chance of damage to the head of the plug.
