OPERATION SAFETY
1. Read and understand the Operator’s Manual and all safety labels before operating the
leveling system.
2. Make sure that all controls are in the manual position before starting the combine.
3. Clear the area of all bystanders, especially children, before starting the leveling system
and during operation.
4. Make sure all safety shields are in place before operating the combine. Never operate
the machine with the shields removed.
5. Keep hands, feet, hair and clothing away from all moving and/or rotating parts.
6. Stay seated in the cab during operation.
7. Operate controls only when sitting in the seat of the combine.
8. To avoid engine damage, do not run the machine for extended periods of time when it is
in the leveled over position.
9. Always travel at a safe speed. Use caution when making turns or traversing ditches.
10. The leveling system is equipped with a maximum level warning lamp. This lamp indicates
when the machine has reached its maximum leveling capability. There are restrictions as
to tread width and tire selection for combines used in harvesting slopes greater than the
maximum leveling capability of the leveling system. Refer to page 13 for important
information on these restrictions.
11. The use of after-market grain tank extensions is prohibited from use on combines
equipped with the Model 2810 leveling system.
12. Level Limit Stops should be used on combines that rely on the limit switches to stop the
leveling prematurely to prevent sheet metal damage (Refer to Page 14).
HYDRAULIC SAFETY
1. Do not search for high-pressure hydraulic leaks without hand and face protection. A tiny,
almost invisible leak can penetrate skin, thereby requiring immediate medical attention.
2. Use cardboard or wood to detect leaks – never your hands!
3. Double check that all is clear before operating hydraulics.
4. Maintain proper hydraulic fluid levels.
5. Ensure all fittings and hoses are in good repair.
6. Do not make any repairs to the leveling system hydraulic system including: cylinders,
valves, hydraulic hoses, adapters, pumps, manifolds, or reservoirs without first contacting
you 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.
SERVICING AND MAINTENANCE SAFETY
1. Review the Operator’s Manual and all safety items before servicing or maintaining the
leveling system.
2. Place the Auto/Off/Manual leveling switch in the “Off” position, stop the combine engine,
wait for any moving parts to stop, block the tires, the header, and the cylinder areas
before servicing, repairing, adjusting, or maintaining the leveling system.
3. Hydraulic oil is under pressure. Use caution when dealing with the hydraulic system.
4. Keep hands, feet clothing and hair away from all moving and/or rotating parts.
5. Clear the area of bystanders, especially children, when carrying out any maintenance,
repairs or making any adjustments.

ELECTRICAL SETTINGS
LIMIT SWITCHES AND MAXIMUM LEVEL LAMP
The leveling system is equipped with left and right level limit switches that disable the
automatic/manual leveling when the combine reaches its maximum leveling capability in
either direction. These switches are preset by the installer at either the maximum leveling
capability of the combine or in some cases at a lesser angle to provide for proper tire
clearance. It is important to note that in the event of a limit switch failure the combine may
continue to level to its maximum capability. Care should be taken to make sure tire
clearances are adequate in the maximum level position to prevent damage to the tire or
chassis in the event that a limit switch failure should occur. The limit switches also actuate
the maximum level lamp that indicates to the operator when the combine has reached its
maximum leveling capability. The operator should daily level the combine to its maximum
level position, with the bulk tank empty, using the manual leveling switch to insure the limit
switches and maximum level lamp are operational. The maximum level lamp will only light
when the manual switch is held into the left or right leveling position or the system is in the
automatic mode when the combine reaches maximum level.
IMPORTANT: With certain tire selections the limit switches can be used to prevent
the need to modify the sheet metal on the left and right side panels of
the combine. Installation of level limit stops is recommended to
prevent sheet metal damage in the event of a limit switch failure. (See
LEVEL LIMIT STOPS on Next Page)
23
HOW TO SET LIMIT SWITCHES
To set the limit switches, park the combine on level ground and set the parking brake.
Then raise the feeder spout and drop the header lift cylinder safety stop. Place the
auto/manual-leveling switch in the manual position. Lean the combine to the left until either
the maximum leveling capabilities of the leveling system are reached or there is
approximately one inch of clearance between the tires and any metal that may interfere
with them. Next, shut off the machine. The limit switches are located on each side of the
gray controller box near the main pivot pin. Loosen the bolt that holds the left limit switch
stop in place. Adjust the left limit switch stop up to the point where you can hear the
contacts on the limit switch snap and move slightly past this point. Repeat this process for
the right limit switch.
If Level Limit Stops are used be sure that the limit switches are set to stop
leveling before the level limit stops make contact. Damage to the cylinders or
other leveling system components may occur if limit switches aren’t set
properly.
LEVEL LIMIT STOPS
On the Model 2810 Leveling System a Level Limiting Spacer Kit can be clamped on the
main leveling cylinders to mechanically stop leveling if the limit switches were to fail. To
determine how many spacers are needed to create a mechanical stop follow these steps:
1. Park the combine on level ground and apply the parking brake.
2. Raise the feeder spout and drop the header lift cylinder safety stop.
3. Place the auto/manual-leveling switch in the manual position and lean the combine
to the left until the limit switch that was set previously stops leveling.
4. Shut off the machine and measure the distance between the packing gland on the
rod end of the cylinder and the ring that is welded to the rod end.
5. Write down this dimension and repeat the process for the right side. (Both sides
must be measured due to the fact that the combine may level further one direction
than the other.)
6. The dimensions obtained will determine how many spacers are needed.
There is no additional charge for the level limit stops (Call Hillco with dimensions to
order).
If Level Limit Stops are used be sure that the limit switches are set to stop
leveling before the level limit stops make contact. Damage to the cylinders or
other leveling system components may occur if limit switches aren’t set
properly.

LEVELING CONTROLLER FUNCTION
The Hillco Model 2810 Leveling System is equipped with a proportional leveling system with
manual control and automatic with manual override control. The clinometer, located in the
control box, monitors changes in slope and corrects the position of the combine’s chassis
using proportional leveling. The clinometer maintains leveling accuracy to +/- 1/10th degrees
by sending the leveling signal to the proportional leveling control valve on the manifold. As
the combine reaches higher degrees of being out of level, the clinometer sends more voltage
to the directional control valve’s coil and pulls the spool open further to allow oil to flow faster
and speed up leveling. As the combine gets closer to +/- 1/10th degrees out of level, less
voltage is sent to the coil to slow leveling.
MECHANICAL ADJUSTMENTS
MODEL 2810 TREAD WIDTH – Slope Restrictions
The Model 2810 Leveling System is designed around a main undercarriage length of
3120mm (122-13/16”), which is identical to the combine’s original axle tube length with
265mm (10-7/16”) axle extensions. The final drives are mounted directly to the
undercarriage and axle extensions are not required. Dual tires are required on all
AFX 8010 combines equipped with the Model 2810 Leveling System. The dual
tire and wheel package sold from Hillco creates a 120”-180” tread spacing.
TIRE SELECTION – Slope Restrictions
Model 2810 Dual Tires – Combines equipped with the Model 2810 Leveling
System must be equipped with the 650/75R32 172A8 R1W dual tire and wheel
package supplied by Hillco or the 620/70R42 160A8 R1W supplied by Case IH to
safely support the weight of the combine.
Model 2810 Steering Tires – Combines equipped with the Model 2810 Leveling
System must be equipped with 480/70R30, 540/65R30, or 600/65R28 rear tires for
proper rear side panel clearance. The 600/65R28 tire has the highest load
carrying capacity and is the tire of choice.
FEEDER ADJUSTMENT FOR TIRE SIZE
Adjust the feeder adapter to obtain the proper header angle and cutter bar height as
shown in the AFX 8010, 8120 or 9120 Operator’s Manual. The chart shown in those
manuals will no longer be a correct guide to adjust the feeder adapter due to the
height increase created by the leveling system.
Important: When rotating the transition throat to obtain proper header angle, pay
special attention to the 60P chain tension. The 60P chain will have to be
lengthened when rotating rearward.
25
Do not use the eyebolt
to adjust the header
angle. The threads will
strip.
26
CONVEYOR DRUM FORE / AFT POSITION
The conveyor drum may need to be repositioned. The position of the conveyor drum
should be set fore or aft so that there is approximately a 1-inch distance between
feeder chain slat tip and the paddle beater.
HEADER AND COMBINE CONNECTION
Refer to the AFX 8010, 8120 or 9120 Operators Manual for instructions on connecting
the header to the combine.
All headers require header kits to function properly on the Model 2810 Leveling System.
Contact your dealer for additional information on these kits.
REAR AXLE WEIGHTING
Proper rear axle weighting of a combine equipped with a 2000 Series leveling system is
critical to the performance and safety of operation. Rear axle weighting increases the tip
angle of the combine to improve down hill maneuvers. The appropriate weighting is
dependent on such items as feeder house length, header selection, and tire selection.
Consult your authorized 2000 Series dealer for weighting information.
Weight can be added to the rear axle through:
1) Calcium Chloride in rear tires
2) CNH Rear Axle Weight System
3) CNH Rear Wheel Weight System
Use caution when using individual turning brakes. Installation of a Hillco Leveling System
transmits additional weight to the rear axle of the combine. Excessive braking to turn can
damage your combine chassis.
The responsibility for making the final determination of appropriate
rear axle weighting lies with the operator.
When first operating the 2000 Series leveling system in hillside conditions, begin operation
on gradual slopes and work up to more severe slopes only after you have determined that
rear axle weighting is appropriate for downhill maneuvers. The first indication of insufficient
rear axle weighting is sluggish or unresponsive steering while traveling down hill. This effect
will worsen if the operator decelerates. Make sure rear axle weighting is sufficient for safe
down hill maneuvers, under normal deceleration, in your most severe down hill conditions.
Use of grain tank extensions other than those provided by the
Combine manufacturer is strictly forbidden. Use of such
Extensions voids both the Hillco and Case IH NEW
Equipment Warranties.
27
REAR AXLE TOE IN
If the rear tire and wheel size changed after the proper sized rear tires were installed the toe
in should be checked. Consult your combine’s operator’s manual on the correct toe in for
your tire and wheel size.
FEEDER CONVEYOR SLIP CLUTCH
The feeder conveyor slip clutch should be adjusted yearly to make sure it will protect all of
the feeder drive components. Consult your combine’s operator’s manual on the correct
procedure for adjusting the slip clutch.
TRANSITION DRIVE CHAIN
Check to see that the transition drive chain is in proper alignment and has proper tension.
Misalignment of these sprockets will cause premature wear of the sprockets and chain.
Chain tension is maintained on the 60-pitch chain with an idler sprocket and on the 80-pitch
chain by moving the jackshaft assembly. Both are located on the right side of the transition.
60-Pitch Chain
Tightener
80-pitch chain is

60P chain will have
to be lengthened
when rotating
rearward.
Do not over tighten idler sprockets or premature chain and sprocket wear will occur.
TRANSITION SLIP CLUTCH
The transition slip clutch is preset at the factory so that damage will not occur to any of the
transition drive components; it cannot be adjusted and will never require any adjustment.
See page 23 for lubrication information.
SHAFT STRIPPERS & NARROWING PLATES
The purpose of the Shaft Stripper is to strip viney material from the paddle and prevent it
from wrapping around the end of the paddle beater shaft causing premature bearing failure.
The Narrowing Plate forces the material in towards the center of the paddles to help prevent
material from wrapping.
The Narrowing Plates are NOT REQUIRED. They are OPTIONAL and intended for use in
viney crops. They can be added or removed at the Operator’s Discretion.
Adjust Shaft Strippers so
they are approximately
1/32” from contacting the
beater shaft.
Improper adjustment may
cause damage to the
beater shaft.

Rotate the Beater Shaft One Full Revolution after adjusting Shaft
Strippers to be sure they don’t contact shaft. Adjust Shaft Strippers so
they are 1/32 inch from contacting beater shaft. Improper adjustment
may cause damage to the beater shaft.

LADDER
If the ladder doesn’t extend and retract properly check the fasteners in all of the pivot
locations and make sure they aren’t over tightened. Over tightening of these fasteners will
cause the ladder to bind.
Make sure that the gas-charged struts keep the ladder fully retracted. Replace the struts if
they appear to be weak. If the ladder doesn’t fully retract permanent damage may occur
during field operation.
LEVELING CYLINDER SAFETY STOPS
When the leveling cylinder safety stops are installed on the leveling cylinders, the
carriage cannot rotate. The stops must be installed before working on or around the
leveling system and also when hauling the combine. It is recommended that the stops
be used during long term storage. When the stops are not being used, they should be
stored on the mount next to the leveling cylinder.

GENERAL
Before operating the combine all shields must be in place and in working condition.
Shield to tire clearance needs to be checked once the correct tires are installed on the
combine. Check to see if the clearance is correct by having someone watch the tire and
shields as the operator leans the combine to the far right and far left. Some tire selections
require limit switches to be set slightly early to allow enough tire clearance between the left
and right front side panels.
SHIELDING
HYDRAULIC SETTINGS
Refer to the Hydraulic Safety section located on page 6 for precautions regarding the
hydraulic system.

The Model 2810 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.
PRESSURE COMPENSATOR SETTING (36’ Draper Headers Only)
The pressure compensator setting must be adjusted to 3200-3300psi to maintain proper
header lift speed when using 36’ Draper headers unless combine is equipped with 90mm left
cylinders. Refer to the AFX 8010, 8120 or 9120 Repair Manual for pressure compensator
location and adjustment procedure.
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 AFX 8010, 8120 or 9120 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.

TIRE INFLATION
Keep the tires properly inflated to the pressures shown in the combine’s operator’s manual
for the front and rear tires. Both under-inflation and over-inflation are detrimental to tire life.
Don’t re-inflate a tire that has been run flat or when there is obvious or suspected damage to
the tire or wheel components. Check the tire pressure weekly or after 50 hours of operation.
WARNING: When inflating tires, use a clip on air chuck and extension hose
long enough to allow you to stand to one side and NOT in front or over the tire
assembly. Use a safety cage if available.
WARNING: A tire can explode during inflation and cause serious injury or
death. Never increase air pressure beyond 35 PSI to seat the bead on the rim.
Replace a tire if it has a defect. Replace a wheel rim, which has cracks, wear
or severe rust. Make sure that all the air is removed from a tire before
removing the tire from the rim. Never use force on an inflated or partially
inflated tire. Make sure the tire is correctly seated before inflating.
