IMPORTANT: A flow control orifice is placed be-
neath the hydraulic fittings in lift/lower manifold
ports C2, C4 and C6. If any of these fittings is re-
moved from the manifold, make sure to remove ori-
fice and label its position for assembly purposes.
Also note location of groove in orifice for assembly
purposes. When installing the orifice in the man-
ifold, make sure that the orifice is flat in the base of
the port. Manifold damage is possible if the orifice
is cocked in the port.
