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.
