identification of components (e.g. P is the supply con-

NOTE: The lift control manifold includes several zero
leak plugs. These plugs have a tapered sealing surface
on the plug head that is designed to resist vibration in-
duced plug loosening. The zero leak plugs also have an
O--ring as a secondary seal. If zero leak plug removal is
necessary, lightly rap the plug head using a punch and
hammer before using an allen wrench to remove the
plug: the impact will allow plug removal with less chance
of damage to the socket head of the plug.
