4-4.1 The rephasing hydraulic lift system con-
tains smaller wing frame cylinders plumbed
in series with larger center frame cylinders. It
is important that the cylinders be connected
in the proper series for the lift system to op-
erate correctly. When the cylinders are fully
extended and held in this position, oil is able
to flow through the cylinders (or rephase)
and allow the cylinders to operate in sync.
This also allows the system to purge any air
that may enter the system without having to
loosen or crack hydraulic lines.
4-4.2 The hydraulic system is not filled with oil
and should be purged of air before transport-
ing and field operations. Carefully hitch the
Wing Coulter Chisel to the tractor and con-
nect the hydraulic lift hoses. Check to make
sure the tractor hydraulic reservoir is full of
the manufacturer’s recommended oil. Slowly
raise the machine, and continue to hold the
hydraulic lever until all lift cylinders are fully
extended. With all cylinders fully extended
remove the 2 X 16 transport lockouts
(See
Figure 4-2). Store transport lockouts as
shown in Figure 4-3. Lower and raise the
unit to verify that all cylinders are working si-
multaneously throughout the stroke. If the
cylinders are not working evenly or together,
fully extend the lift cylinders and continue to
hold the lever to purge any remaining air. Do
not loosen any hoses or fittings. Recheck
tractor reservoir to make sure it is within op-
erating limits.
4-4.3 Always fully extend the cylinders and
hold the lever to ensure the cylinders are
rephased before starting any field operation.
This will keep all cylinders in time and frame
sections level when operating.
