HYDRAULIC
SETTINGS
Refer to the Hydraulic Safety section located on page 6 for precautions regarding the
hydraulic system.
The Model 3700S Leveling System utilizes the existing auxiliary combine hydraulic system
for their hydraulic requirements with the exception of the addition of a stand-alone leveling
manifold located behind the left shield to the rear of the operator’s platform. The hydraulic
schematic located in the rear of this manual covers the leveling system circuitry. Consult
your combine’s operator’s manual or contact your Case-IH dealer for diagnostics and
maintenance regarding the remainder of the hydraulic system.
IMPORTANT:
All adjustments on the hydraulic system are preset at the
factory for optimal leveling and header trim performance. DO
NOT MAKE ANY ADJUSTMENTS TO THESE SETTINGS
WITHOUT FIRST CONTACTING YOUR AUTHORIZED HILLCO
DEALER.
HYDRAULIC
HOSES
Inspect hydraulic system for leaks, damaged hoses, improper routing, and loose fittings.
Hydraulic hoses that are not routed correctly could become worn from working against
abrasive edges or moving parts. If abrasions or holes do occur, the hydraulic hoses can only
be repaired by replacement.
Do not attempt repairs with tape or cements.
High pressure
will burst such repairs and cause system failure and possible injury.
Hydraulic Hose Connections – When tightening loose hoses on the cylinders, pump, etc.,
always use one wrench to keep the hose from twisting and another wrench to tighten the
union. Excessive twisting will shorten hose life and allow the fitting to loosen during
operation. Do not over-tighten fittings or adapters.
Refer to the Case IH® 5088/6088/7088 Operator’s Manual for information regarding
hydraulic oil check intervals, and reservoir fluid levels. Leveling and header trim speeds are
preset at the factory. If different speeds are desired please contact your Hillco dealer.
HYDRAULIC
CYLINDERS
IMPORTANT:
Each leveling cylinder is equipped with a safety valve (counterbalance valve)
that is in place to prevent unintentional leak down of the cylinder. These safety
valves are preset at the factory, and should not be adjusted.
DANGER:
Do not make any repairs to the cylinders, disconnect valves, or
disconnect any hoses connected to the cylinders, counterbalance valves, bulkhead
mount or manifold without first contacting your authorized Hillco dealer. These
hydraulic components stabilize the chassis of the combine. Improper repair or
replacement of these components could lead to uncontrolled leveling of the
combine’s chassis. The leveling cylinder safety stops can be used to prevent
accidental tipping of the combine during repair.
