INTRODUCTION
Safety rules - Ecology and the environment
Soil, air, and water quality is important for all industries and life in general. When legislation does not yet rule the
treatment of some of the substances that advanced technology requires, sound judgment should govern the use and
disposal of products of a chemical and petrochemical nature.
Familiarize yourself with the relative legislation applicable to your country, and make sure that you understand this
legislation. Where no legislation exists, obtain information from suppliers of oils, filters, batteries, fuels, anti-freeze,
cleaning agents, etc., with regard to the effect of these substances on man and nature and how to safely store, use,
and dispose of these substances.
Helpful hints
• Avoid the use of cans or other inappropriate pressurized fuel delivery systems to fill tanks. Such delivery systems
may cause considerable spillage.
• In general, avoid skin contact with all fuels, oils, acids, solvents, etc. Most of these products 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 you drain fluids such as used engine coolant mixtures, engine oil, hydraulic fluid, brake fluid,
etc. Do not mix drained brake fluids or fuels with lubricants. Store all drained fluids safely until you can dispose of
the fluids in a proper way that complies with all local legislation and available resources.
• Do not allow coolant mixtures to get into the soil. Collect and dispose of coolant mixtures properly.
• The air-conditioning system contains gases that should not be released into the atmosphere. Consult an air-condi-
tioning specialist or use a special extractor to recharge the system properly.
• Repair any leaks or defects in the engine cooling system 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. Penetrating weld splatter may burn a hole or weaken hoses, allowing the loss of oils,
coolant, etc.
Battery recycling
Batteries and electric accumulators contain several substances that can have a harmful
effect on the environment if the batteries are not properly recycled after use. Improper
disposal of batteries can contaminate the soil, groundwater, and waterways. NEW
HOLLAND strongly recommends that you return all used batteries to a NEW HOLLAND
dealer, who will dispose of the used batteries or recycle the used batteries properly. In
some countries, this is a legal requirement.
Mandatory battery recycling
NOTE: The following requirements are mandatory in Brazil.
Batteries are made of lead plates and a sulfuric acid solution. Because batteries contain heavy metals such as lead,
CONAMA Resolution 401/2008 requires you to return all used batteries to the battery dealer when you replace any
batteries. Do not dispose of batteries in your household garbage.
Points of sale are obliged to:
• Accept the return of your used batteries
• Store the returned batteries in a suitable location
• Send the returned batteries to the battery manufacturer for recycling

INTRODUCTION
Basic instructions hardware
General
Your tractor has been built using metric hardware.
NOTE: Be sure to use the hardware specified when using tapped holes, as trying to install a metric bolt in an inch
thread, or an inch bolt in a metric thread, will damage the thread.
Certain hardware must be tightened to specific torque specifications. If specific torque specifications are not noted,
tighten the hardware to the standard torque chart specification listed in this manual.
Plating
Hardware used on NEW HOLLAND balers is plated with zinc chromate (gold color). Gold colored hardware has
different torquing requirements from unplated or zinc plated (silver color) hardware because of the difference in the
coefficient of friction of the plating material. The torque charts in this manual list the correct specifications for gold,
silver, and unplated bolts.
Nut tightening
Whenever possible, the nut should be tightened, not the head of the bolt. When tightening using the bolt head, the
clamp load can be lost because some of the torque applied twists the bolt instead of tensioning (stretching) it. The
tension on the bolt is what holds the joint together.
Approximately 90% of the torque applied during assembly goes to overcoming friction between the parts. The other
10% is used to tension (stretch) the bolt. After assembly, the frictional forces disappear, which is the basis for the
saying 'If it does not fail during assembly, it will not fail in service.' The bolt may later fail due to other factors, but not
from being over tightened.
Locknuts
Most locknuts are coated with a special lubricant that is dry to the touch. Anytime a locknut is used, a lower than
normal torque is required. Refer to the torque charts in this manual for specific values.
Jam nuts
When using a jam nut to lock a regular nut, the jam nut should be installed first and tightened to one half the recom-
mended torque, then held in place while installing a regular nut to the recommended torque.
Thread lubrication
The addition of antiseize compound, Molykote, oil, graphite, or any other lubricant to a bolt decreases the friction
between it and a nut. This makes it necessary to reduce the recommended torque to prevent over tensioning of the
bolt. When using the torque charts in this manual, decrease the value by 20% whenever a lubricant is used.

INTRODUCTION
Torque - Standard torque data for hydraulic connections
General information
• Hydraulic connections require a minimum assembly torque in order to provide zero leakage at rated pressure with
adequate fatigue resistance. Over-torquing of a hydraulic connection can also lead to leakage or failure. For some
connections, NEW HOLLAND requires a different torque value than is listed in the ISO and SAE standards.
• The torque values in this document should be used whenever possible or applicable.
NOTICE: Always follow the instructions in this manual for specific torque values when you service components.
The information in this section is for general guidance only when a procedure contains no specific torque value.
Tolerance
• The tolerance for all torque values is ± 10 %. This tolerance must include all assembly variation, not only the torque
wrench repeatability.
Lubrication
Application of grease or other lubricants to hydraulic connectors should be avoided. If clean hydraulic oil is already
on the connection, it is not required to remove the oil. Generally, application of grease:
• May cause a significant change in the torque required to properly tighten the connection.
• May reduce the connection’s resistance to vibration.
• Excessive grease may displace an elastomer seal during tightening.
• Grease extrusion when connection is tightened may be mistaken for leakage.
NEW HOLLAND products generally use O-Ring Boss (ORB) connectors that have Teflon™-coated O-rings, eliminat-
ing the need for O-ring lubrication during installation. For connections which are made into aluminum manifolds or
with stainless steel connectors, it may be required to apply a lubricant to prevent galling.
Use of LOCTITE® and other thread-locking compounds is prohibited. These compounds:
• May cause a significant change in the torque required to properly tighten the connections.
• Reduce the serviceability of the joint.
• May prevent the O-ring from properly sealing if the compound gets on the O-ring.

INTRODUCTION
Basic instructions - Shop and assembly
Shimming
For each adjustment operation, select adjusting shims and measure the adjusting shims individually using a microm-
eter, then add up the recorded values. Do not rely on measuring the entire shimming set, which may be incorrect, or
the rated value shown on each shim.
Rotating shaft seals
For correct rotating shaft seal installation, proceed as follows:
1. Before assembly, allow the seal to soak in the oil it will be sealing for at least thirty minutes.
2. Thoroughly clean the shaft and check that the working surface on the shaft is not damaged.
3. Position the sealing lip facing the fluid.
NOTE: With hydrodynamic lips, take into consideration the shaft rotation direction and position the grooves so that
they will move the fluid towards the inner side of the seal.
4. Coat the sealing lip with a thin layer of lubricant (use oil rather than grease). Fill the gap between the sealing lip
and the dust lip on double lip seals with grease.
5. 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.
6. While you insert the seal, check that the seal is perpendicular to the seat. When the seal settles, make sure that
the seal makes contact with the thrust element, if required.
7. To prevent damage to the seal lip on the shaft, position a protective guard during installation operations.
O-ring seals
Lubricate the O-ring seals before you insert them in the seats. This will prevent the O-ring seals from overturning and
twisting, which would jeopardize sealing efficiency.
Sealing compounds
Apply a sealing compound on the mating surfaces when specified by the procedure. Before you apply the sealing
compound, prepare the surfaces as directed by the product container.
Spare parts
Only use CNH Original Parts or NEW HOLLAND Original 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 NEW HOLLAND Original Parts can
offer this guarantee.
When ordering spare parts, always provide the following information:
• Machine model (commercial name) and Product Identification Number (PIN)
• Part number of the ordered part, which can be found in the parts catalog

INTRODUCTION
Protecting the electronic and/or electrical systems during charging and welding
To avoid damage to the electronic and/or electrical systems, always observe the following practices:
1. Never make or break any of the charging circuit connections when the engine is running, including the battery
connections.
2. Never short any of the charging components to ground.
3. Always disconnect the ground cable from the battery before arc welding on the machine or on any machine
attachment.
• Position the welder ground clamp as close to the welding area as possible.
• If you weld in close proximity to a computer module, then you should remove the module from the machine.
• Never allow welding cables to lie on, near, or across any electrical wiring or electronic component while you
weld.
4. Always disconnect the negative cable from the battery when charging the battery in the machine with a battery
charger.
NOTICE: If you must weld on the unit, you must disconnect the battery ground cable from the machine battery.
The electronic monitoring system and charging system will be damaged if this is not done.
5. Remove the battery ground cable. Reconnect the cable when you complete welding.
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.

INTRODUCTION
General specification
Fatty Acid Methyl Ester Biodiesel (Biodiesel Fuel) consists of a family of fuels derived from vegetable oils treated with
methyl esters.
NOTICE: Biodiesel Fuel blends are approved for your engine only if they comply with EN14214 Specification Stan-
dards or ASTM D6751.
NOTICE: It is imperative that you check which blend is approved for your engine with your NEW HOLLAND dealer.
Be aware that the use of Biodiesel Fuel that does not comply with the Standards mentioned above could lead to
severe damage to the engine and fuel system of your machine. The use of fuels that are not approved may void NEW
HOLLAND Warranty coverage.
Biodiesel fuel usage conditions
NOTICE: The Biodiesel Fuel must meet the fuel Specification mentioned above.
Biodiesel Fuel must be purchased from a trusted supplier that understands the product and maintains good fuel qual-
ity. Biodiesel Fuel must be pre-blended by the supplier. Mixing Biodiesel Fuels on-site can result incorrect mixture
that can lead to problems with both engine and fuel system.
Engine performance is affected by the use of Biodiesel Fuel. There may be up to 12 % reduction in power or torque
depending on the blend used.
NOTICE: DO NOT modify the engine and/or injection pump settings to recover the reduced performance.
The reduced power must be accepted if using any Biodiesel Fuel blend.
Some modification may be required to allow your engine to run Biodiesel Fuel. Consult you dealer for complete
information on these modifications.
Biodiesel Fuel has a higher cloud point than Diesel Fuel.
NOTICE: The use of high Biodiesel Fuel blends are not recommended in cold weather conditions.
With Biodiesel Fuels, it may be necessary to change the engine oil, engine oil filter and fuel filter elements more
frequently than with Diesel Fuels. Biodiesel Fuel can remove rust and particles from the inside of on-site fuel storage
tanks that would normally adhere to the sides of the tank. Like particle deposits that commonly occur with Diesel Fuel,
these particles can become trapped by the machine fuel filters, causing blockage and shortening filter life. In cold
weather, this is more likely to happen. Consult your NEW HOLLAND dealer for information on cold weather operation
and proper maintenance intervals when using any Biodiesel Fuel blend.
When handling Biodiesel Fuel, care must be taken not to allow water into the fuel supply. Biodiesel Fuel will actually
attract moisture from the atmosphere.
Fuel tanks must be kept as full as possible to limit the amount of air and water vapors in them. It may be necessary
to drain the fuel filter water tap more frequently.
Potential oxidation and stability could be a problem with the fuel stored in the machine.
NOTICE: Machines must not be stored for more than three months with Biodiesel Fuel blends in the fuel system.
If long storage periods are necessary, the engine must run on Diesel Fuel for 20 hours to flush the Biodiesel Fuel out
of the engine fuel system prior to storage.
NOTICE: Biodiesel Fuel must not be stored in on-site storage tanks for more than three months.
Any spillage of Biodiesel Fuel must be cleaned up immediately before it can cause damage to the environment and
the paint finish of the machine.
Before using Biodiesel Fuel blends you should consult with your dealer to receive full information about the approved
blend for your machine and any detailed conditions of its usage.
NOTICE: Be aware that not fulfilling the requirements and conditions of Biodiesel Fuel usage will void your machine’s
NEW HOLLAND Warranty coverage.
