1. The rephasing hydraulic lift system contains 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 operate 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.
2. The hydraulic system is not filled with oil and should
be purged of air before transporting and field
operations. Carefully hitch the Wing Coulter Chisel to
the tractor and connect 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 (See Figure 4-3.) Lower and raise the unit
to verify that all cylinders are working simultaneously
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 operating limits.
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.
