Figure 4-2: Transport Lock Locations
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.
a. Carefully hitch the Finisholl 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.
b. Slowly raise the machine, and continue to hold
the hydraulic lever until all lift cylinders are fully
extended.
c. With all cylinders fully extended, remove the
transport locks See Figure
the unit to verify that all cylinders are working
simultaneously throughout the stroke.
d. 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.

OPERATION AND MAINTENANCE
3. Always fully extend the lift 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.
4. Servicing – Before servicing any hydraulic
component, lower the implement to the ground and
relieve all system pressure. If a hydraulic component
is disconnected, repaired, or replaced, it will be
necessary to purge the system of air before
operation.
NOTE
If performing service or repair work, lower the
machine to the ground and relieve hydraulic
pressure.
Hydraulic Fold System
The Finisholl is equipped with a hydraulic fold system to
raise and lower the wing frames for narrow transport.
Figure 4-3: Hydraulic Leak Detection

Escaping hydraulic fluid can cause serious
personal injury. Relieve system pressure before
repairing, adjusting, or disconnecting. Wear
proper hand and eye protection when searching
for leaks. Use cardboard instead of hands
Figure 4-3. Keep all components (cylinders,
hoses, fittings, etc.) in good repair.
1. Be sure the fold system is fully charged with hydraulic
oil before attempting to fold/unfold the unit. Air in the
system can allow uncontrolled dropping of the wing
frames causing serious personal injury or machine
damage. The system needs to be charged with oil
initially and any time the system opened for repair
such as cylinder, hose, or fitting replacement/repair.
