INTRODUCTION
Safety rules - Personal safety
General safety rules
Use caution when operating the machine on slopes. Raised equipment, full tanks and other loads will change the
center of gravity of the machine. The machine can tip or roll over when near ditches and embankments or uneven
surfaces.
Never permit anyone other than the operator to ride on the machine.
Never operate the machine under the influence of alcohol, drugs, or while otherwise impaired.
While driving on the road, the seat swivel position must always be straight forward and locked in position with no
rotation. The seat swivel should only be rotated for in field operation.
Stay off slopes too steep for safe operation. Shift down before you start up or down a hill with a heavy load. Avoid
“free wheeling.”
Do not drive on roads, or at high speed anywhere, with the differential lock engaged. Difficult steering will occur, and
can result in an accident. In field operation, use the differential lock for traction improvement, but release for turning
at row ends.
Do not exceed implement transport speed or the speed rating on the implement tires. Review the implements Oper-
ator’s Manual for specifications. Failure to comply could result in death or serious injury.
For speeds up to 16 km/h (10 mph), make sure that the weight of a trailed vehicle that is not equipped with brakes
does NOT EXCEED 1.5 times the Tractor weight. For speeds up to 40 km/h (25 mph), make sure that the weight of
the trailed vehicle that is not equipped with brakes, does NOT EXCEED the weight of the Tractor. Stopping distance
increases with increasing speed as the weight of the towed load increases, especially on hills and slopes.
Rear upset can result if pulling from wrong location on tractor. Hitch only to the drawbar. Use three point hitch only
with the implements designed for its use – not as a drawbar.
Do not look directly into the front or rear HID (high intensity discharge) lamps. Eye damage can occur.
Do not tamper with the ballast on the front or rear high intensity discharge (HID) lamp since it uses high voltage.
Personal injury or death can occur.
To avoid possible eye damage from microwave signals emitted by the radar sensor, do not look directly into the sensor
face.
When digging or using ground engaging attachments be aware of buried cables. Contact local utilities to determine
the locations of services.
Pay attention to overhead power lines and hanging obstacles. High voltage lines may require significant clearance
for safety.
Hydraulic oil or diesel fuel leaking under pressure can penetrate the skin, causing serious injury or infection.
• DO NOT use your hand to check for leaks. Use a piece of cardboard or paper.
• Stop engine, remove key and relieve the pressure before connecting or disconnecting fluid lines.
• Make sure all components are in good condition and tighten all connections before starting the engine or pressur-
izing the system.
• If hydraulic fluid or diesel fuel penetrates the skin, seek medical attention immediately.
• Continuous long term contact with hydraulic fluid may cause skin cancer. Avoid long term contact and wash the
skin promptly with soap and water.
Keep clear of moving parts. Loose clothing, jewelry, watches, long hair, and other loose or hanging items can become
entangled in moving parts.
Wear protective equipment when appropriate.

INTRODUCTION
DO NOT attempt to remove material from any part of the machine while it is being operated or components are in
motion.
Make sure all guards and shields are in good condition and properly installed before operating the machine. Never
operate the machine with shields removed. Always close access doors or panels before operating the machine.
Dirty or slippery steps, ladders, walkways, and platforms can cause falls. Make sure these surfaces remain clean and
clear of debris.
A person or pet within the operating area of a machine can be struck or crushed by the machine or its equipment. DO
NOT allow anyone to enter the work area.
Raised equipment and/or loads can fall unexpectedly and crush persons underneath. Never allow anyone to enter
the area underneath raised equipment during operation.
Never operate engine in enclosed spaces as harmful exhaust gases may build up.
Before starting the machine, be sure that all controls are in neutral or park lock position.
Start the engine only from the operator’s seat. If the safety start switch is bypassed, the engine can start with the
transmission in gear. Do not connect or short across terminals on the starter solenoid. Attach jumper cables as
described in the manual. Starting in gear may cause death or serious injury.
Always keep windows, mirrors, all lighting, and Slow Moving Vehicle (SMV) emblem clean to provide the best possible
visibility while operating the machine.
Operate controls only when seated in the operator’s seat, except for those controls expressly intended for use from
other locations.
Before leaving the machine:
1. Park machine on a firm level surface.
2. Put all controls in neutral or park lock position.
3. Engage park brake. Use wheel chocks if required.
4. Lower all hydraulic equipment — Implements, header, etc.
5. Turn off engine and remove key.
When, due to exceptional circumstances, you would decide to keep the engine running after leaving the operator’s
station, then the following precautions must be followed:
1. Bring the engine to low idle speed.
2. Disengage all drive systems.
3. WARNING
Some components may continue to run down after disengaging drive systems.
Make sure all drive systems are fully disengaged.
Failure to comply could result in death or serious injury.
W0113A
Shift the transmission into neutral.
4. Apply the parking brake.

Engine - Engine and crankcase
Engine - Change fluid - Changing engine oil and filter
NOTE: Reduce to 300 hours or less if CASE IH AKCELA UNITEK NO. 1™ SBL CJ-4 is not used.
Change the engine oil and filter every 600 hours or once a
year or before storage, whichever occurs first. Your dealer
has approved oil and filters. Do not use other types of oil
or filters.
NOTE: For best results change the oil and filter while the
engine is still warm to the touch from operation (not hot).
The tractor must be on a level surface.
Remove the engine side shields.
9L engine
1. Remove the oil pan drain plug and drain the oil from the
engine into a container.
2. After all oil has drained, install new washer 98474302
on drain plug, center washer on plug and install drain
plug. Torque drain plug to 30 N·m (22 lb ft).
3. Clean the area around the filter head and housing on
the left side of the engine. Place a container under the
oil filter and turn the filter housing counterclockwise to
loosen with a 51 mm (2 in) wrench. After all oil has
drained from the filter, remove the housing with filter.

4. Install the new filter cartridge and O-ring. Lightly oil new
O-ring.
4. Reinstall the filter assembly onto the tractor. Do not
over tighten or O-ring will leak.
