Safety rules - Ecology and the environment
Soil, air, and water are vital factors of agriculture and life in general. When legislation does not yet rule the treatment
of some of the substances required by advanced technology, sound judgment should govern the use and disposal of
products of a chemical and petrochemical nature.
NOTE: The following are recommendations that may be of assistance:
• Become acquainted with and ensure that you understand the relative legislation applicable to your country.
• Where no legislation exists, obtain information from suppliers of oils, filters, batteries, fuels, antifreeze, cleaning
agents, etc., with regard to their effect on man and nature and how to safely store, use, and dispose of these
substances.
• Agricultural consultants will, in many cases, be able to help you as well.
Helpful hints
• Avoid filling tanks using cans or inappropriate pressurized fuel delivery systems that may cause considerable
spillage.
• In general, avoid skin contact with all fuels, oils, acids, solvents, etc. Most of them contain substances that may be
harmful to your health.
• Modern oils contain additives. Do not burn contaminated fuels and or waste oils in ordinary heating systems.
• Avoid spillage when draining off used engine coolant mixtures, engine, gearbox and hydraulic oils, brake fluids, etc.
Do not mix drained brake fluids or fuels with lubricants. Store them safely until they can be disposed of in a proper
way to comply with local legislation and available resources.
• Do not allow coolant mixtures to get into the soil Collect and dispose of coolant mixtures properly.
• Do not open the air-conditioning system yourself. It contains gases that should not be released into the atmosphere.
Your CNH dealer or air conditioning specialist has a special extractor for this purpose and will have to recharge the
system properly.
• Repair any leaks or defects in the engine cooling or hydraulic system immediately.
• Do not increase the pressure in a pressurized circuit as this may lead to a component failure.
• Protect hoses during welding as penetrating weld splatter may burn a hole or weaken them, allowing the loss of
oils, coolant, etc.

Shimming
For each adjustment operation, select adjusting shims and measure individually using a micrometer, then add up
the recorded values. Do not rely on measuring the entire shimming set, which may be incorrect, or the rated value
indicated on each shim.
Rotating shaft seals
For correct rotating shaft seal installation, proceed as follows:
• before assembly, allow the seal to soak in the oil it will be sealing for at least thirty minutes.
• thoroughly clean the shaft and check that the working surface on the shaft is not damaged.
• position the sealing lip facing the fluid; with hydrodynamic lips, take into consideration the shaft rotation direction
and position the grooves so that they will deviate the fluid towards the inner side of the seal.
• coat the sealing lip with a thin layer of lubricant (use oil rather than grease) and fill the gap between the sealing lip
and the dust lip on double lip seals with grease.
• insert the seal in its seat and press down using a flat punch or seal installation tool. Do not tap the seal with a
hammer or mallet.
• whilst inserting the seal, check that it is perpendicular to the seat; once settled, make sure that it makes contact
with the thrust element, if required.
• to prevent damaging the seal lip on the shaft, position a protective guard during installation operations.
O-Ring seals
Lubricate the O-RING seals before inserting them in the seats, this will prevent them from overturning and twisting,
which would jeopardise sealing efficiency.
Sealing compounds
Apply one of the following sealing compounds on the mating surfaces when specified: SILMATE® RTV1473, or
LOCTITE® RTV 598™ or LOCTITE® INSTANT GASKET 587™ BLUE. Before applying the sealing compound, prepare
the surfaces as directed on product container or as follows:
• remove any incrustations using a metal brush.
• thoroughly de-grease the surfaces using a locally approved cleaning agent such as safety solvent or brake parts
cleaner.
Spare parts
Only use "CNH Original Parts" or " CNH Parts".
Only genuine spare parts guarantee the same quality, duration and safety as original parts, as they are the same
parts that are assembled during standard production. Only "CNH Original Parts" or " CNH Parts" can offer this
guarantee.
When ordering spare parts, always provide the following information:
• machine model (commercial name) and serial number
• part number of the ordered part, which can be found in the "Microfiches" or the "Service Parts Catalogue", used for
order processing

Protecting the electronic/electrical system during charging or welding
To avoid damage to the electronic/electrical systems, always observe the following:
1. Never make or break any of the charging circuit connections, including the battery connections, when the engine
is running.
2. Never short any of the charging components to ground.
3. Always disconnect the ground cable from the battery before arc welding on the combine or on any header
attached to the combine.
• position the welder ground clamp as close to the welding area as possible
• if welding in close proximity to a computer module, then the module should be removed from the combine
• never allow welding cables to lay on, near or across any electrical wiring or electronic component while welding
is in progress
4. Always disconnect the negative cable from the battery when charging the battery in the combine with a battery
charger.
NOTICE: If welding must be performed on the unit, either the combine or the header (if it is attached), the battery
ground cable must be disconnected from the combine battery. The electronic monitoring system and charging system
will be damaged if this is not done.
Remove the battery ground cable. Reconnect the cable when welding is completed.
WARNING
Battery acid causes burns. Batteries contain sulfuric acid.
Avoid contact with skin, eyes or clothing. Antidote (external): Flush with water. Antidote (eyes): flush
with water for 15 minutes and seek medical attention immediately. Antidote (internal): Drink large
quantities of water or milk. Do not induce vomiting. Seek medical attention immediately.
Failure to comply could result in death or serious injury.

F4DECOMPLETE 1
The NEF F4DFE engines are turbocharged, four-stroke diesel engines with four or six cylinders and with four valves
per cylinder.
The NEF F4DFE engines have high-pressure fuel injection (common rail system). The control of the NEF F4DFE
engines is fully electronic in order to optimize the working process. The control of the NEF F4DFE engines also takes
into account the operating characteristics, the limitation of emissions and the fuel consumption as far as possible.
NOTE: Data, performance information and power are only valid if the configuration fully matches the installation guide-
lines that FPT (Fiat Powertrain Technologies) provided.
Furthermore, after an overhaul, the use of the device must correspond to the originally specified power and engine

Engine - Service instruction Maintenance procedures
WARNING
Chemical hazard!
When handling fuel, lubricants, and other service chemicals, follow the manufacturer's instructions.
Wear Personal Protective Equipment (PPE) as instructed. Do not smoke or use open flame. Collect
fluids in proper containers. Obey all local and environmental regulations when disposing of chemi-
cals.
Failure to comply could result in death or serious injury.
W0371A
WARNING
Escaping fluid!
Hydraulic fluid or diesel fuel leaking under pressure can penetrate the skin and cause infection or
other injury. To prevent personal injury: Relieve all pressure before disconnecting fluid lines or per-
forming work on the hydraulic system. Before applying pressure, make sure all connections are tight
and all components are in good condition. Never use your hand to check for suspected leaks under
pressure. Use a piece of cardboard or wood for this purpose. If injured by leaking fluid, see your
doctor immediately.
Failure to comply could result in death or serious injury.
W0178A
CAUTION
Burn hazard!
Hot coolant can spray out if you remove the filler cap while the system is hot. After the system has
cooled, turn the filler cap to the first notch and wait for all pressure to release before proceeding.
Failure to comply could result in minor or moderate injury.
C0043A
WARNING
Rotating parts!
The engine is running. Keep clear of rotating fans and belts.
Failure to comply could result in death or serious injury.
W0275A
Engine oil level check
The check can be made using the dipstick (1) placed on
the right hand side of the Engine Control Unit (ECU).
NOTICE: The check must be executed when the engine is
off and possibly cool.
Draw off the rod from it's slot and check that the level is
within the etched tags of minimum and maximum level.
Whether it should be difficult to make the evaluation, pro-
ceed cleaning the rod using a clean cloth with no contami-
nation and put it back in it's slot. Draw it off again and check
the level.
In case the level results being close to the tag showing min-
imum level, provide filling lubrication of the engines com-
ponents.
Add oil through the upper top or through the lateral top (2).
During filling operation, the tops must be removed as well
as the rod in order to make the oil flow easier.

Combustion system inspection
The check must be executed both when the engine off and
when it is running.
The check operation consists in examining the fuel
pipelines running from the tank to the pre-filter (if provided
in the specific equipment), to the filter, to the high pressure
pump and to the rail diffuser and from this last one to the
head.
Special attention must be paid to the connections on the
high pressure pipelines.
Cooling system inspection
The check must be executed both when the engine is off
and when it is running.
Check the pipelines from the engine to the radiator, from
the expansion tank and vice-versa. Find out any blow-by,
verify the status of the pipes specially close to the holding
strips.
Verify that the radiator is clean, the correct working of the
fan flywheels, the presence of any leakage from the con-
nectors, from the manifold and from the radiating unit.
The density of the cooling liquid must be checked any how
every year before winter season and be replaced in any
case every two years.
NOTE: In case of new filling, proceed bleeding the system,
through the bleeds on the engine.
If bleeding of the system is not carried out, serious inconve-
nience might be caused to the engine due to the presence
of air pockets in the engine's head.
Lubricating system inspection
The check must be executed both when the engine is off
and when it is running.
Verify the presence of any oil leakage or blow-by from the
head, from the engine pan or from the heat exchanger.
Inspection of water presence within the fuel
filter or pre-filter
The components of the common rail system can be dam-
aged very quickly in presence of water or impurity within
the fuel.
Timely proceed operating on the pre-filter (not available on
the engine block) to carry out the drainage of the water
within the feed circuit.

Inspection of drive belt tensioning
The drive belt tensioning control is made using an au-
tomatic tensioning device therefore no intervention is
required apart from checking the wear status of the belt
itself.
Inspection and setting of tappet clearance
Adjust clearance between rockers and valves using
setscrew wrench (1), box wrench (2) and feeler gauge (3).
Valve clearance
• Intake - 0.20 - 0.30 mm (0.008 - 0.012 in)
• Exhaust - 0.45 - 0.55 mm (0.018 - 0.022 in)

Engine oil and filter replacement
Due to the several applications, the pan shape and the
oil quantity can change slightly. However, the following
operations are valid for all applications.
We recommend to carry out the oil drainage when the en-
gine is hot.
Place a proper container for the oil collecting under the pan
connected with drain plug.
Unscrew the plug and then take out the control dipstick and
the inserting plug to ease the downflow of the lubrication oil.
After the complete drainage, screw the plug and carry out
the clean oil filling.
NOTICE: Use only recommended oil or oil having the re-
quested features for the correct engine functioning. In case
of topping up, don't mix oils having different features. If you
don't comply with these rules, the service warranty is no
more valid.
Check the level through the dipstick until when the filling is
next to the maximum level notch indicated on the dipstick.
