OPERATION AND MAINTENANCE
4-3
1. The rephasing hyd raulic lift system contains smaller
wing frame cylinder s plum b e d in series with larger
center frame cylinders. It is important that the
cylinders be connected in the prop er 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 operat e in syn c. T his als o allows th e
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 hydr au lic re ser vo ir is
full of the manufacturer’s recommended oil. Slowly
raise the machine, and continue to hold the hydr aulic
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 tra n spo r t locko u ts
as shown (See Figure 4-3.) Lower and raise the unit
to verify that all cylinders are working simultaneo usly
throughout the stroke. If the cylinders are not working
evenly or together, fully extend the lift cylinders and
continue to hold the lever to pu rge any r emaining 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.
