and Installing Hydraulic System Components in
this section.
WARNING
If liftmanifold isattached to machine, makesure
that cutting units are fully lowered before loos-
eninghydraulic linesor cartridge valvesfrom lift
manifold. If cutting units are raised as compo-
nents are loosened in manifold, cutting units
may drop unexpectedly.
NOTE: ThehydraulicmanifoldshowninFigure71uses
several zero leak plugs. These plugs have a tapered
sealing surface on the plug head that is designed to re-
sist vibration induced plug loosening. The zero leak
plugs also havean O--ring to providea 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
headoftheplug.Wheninstallingplugsintothemanifold,
torque plugs to the values identified in Figure 71.
For cartridge valve service procedures, see Control
Manifold Cartridge Valve Service in this section. Refer
to Figure 71 for lift manifold cartridge valve and plug
installation torque.
