NOTE: The ports on the manifold are marked for easy
identification of components. Examples: BV is the deck
circuit braking valve and P1 is the gear pump c onnection
port (see Hydraulic Schematic to identify the function of
the hydraulic lines and cartridge valves at each port
location).
NOTE: The Groundsmaster 3500--D hydraulic man-
ifold uses several zero leak plugs. These plugs have a
tapered sealing surface on the plug head that is de-
signed to resist vibration induced 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 r emove the plug: the impact will allow
plug removal with less chance of damage to the socket
head of the plug.
