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.
11.The use of after-market grain tank extensions is prohibited from use on combines
equipped with the Model 3700S leveling system.
12. Level Limit Stops should be used on combines that rely on the limit switches to stop
leveling prematurely to prevent sheet metal damage (Look in Table of Contents for Level
Limit Stops).
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.

10
HIGHWAY OPERATION AND TRANSPORT SAFETY
1. Check with local authorities regarding combine transport on public roads. Obey all
applicable regulations and laws.
2. Check clearance elevations and widths of combine for travel near power lines, bridges,
trees, etc.
3. Make sure the Auto/Off/Manual leveling toggle switch is in the “Off” position for all
transport and highway travel situations.
4. Always travel at a safe speed. Use caution when making corners or meeting traffic.
SAFETY LABELS
Familiarize yourself with the location of all safety labels. Read them carefully to understand
the safe operation of your machine.
“Read Operator’s Manual” Symbol
Decals, which display the “Read Operator’s Manual” symbol, are
intended to direct the operator to the Operator’s Manual for
further information regarding maintenance, adjustments and/or
procedures for particular areas of the leveling system. When a
decal displays this symbol refer to the Operator’s Manual for
further instructions.
TO APPLY NEW OR REPLACEMENT LABELS:
1. Make sure the label area is smooth by removing any debris such as dirt or old labels.
2. Wash the area with soap and water and then dry it thoroughly.
3. After the area has completely dried, peal the backing off the safety label and place it onto
the cleaned area.
4. Make sure all areas of the label have adhered to the machine by pressing down on the
entire face of the label, including the corners.

engaged. The automatic leveling controller monitors changes in slope and corrects chassis
position to maintain a level chassis position. The Manual Left/Right Leveling Buttons will
override the automatic leveling controller while the switch is depressed. Upon release of the
switch, the leveling system will return to automatic leveling mode.
MANUAL: Push the A/M (Auto/Manual) Leveling Button once to enter the Manual Leveling
mode (M will be displayed). In Manual mode the Manual Left/Right leveling switches will
