FEDERAL EMISSIONS WARRANTY
(California owner’s emissions warranty is covered elsewhere)
New Holland warrants that your new 1996 and later heavy-duty off-road diesel engine was designed, built, and equipped to conform to applicable
U.S. Environmental Protection Agency regulations for a period of use of five years or 3,000 hours of operation, whichever occurs first.
The new model year, class of diesel engine, and emission application determination for your engine are identified on the emission control
information label affixed to the top of your engine’s rocker arm cover. The warranty period begins on the date the new equipment is sold to the first
retail purchaser.
Any emission control system parts which are proven defective during normal use will be repaired or replaced during the warranty period. The
warranty repairs and service will be performed by any authorized New Holland dealer at the dealer’s place of business, with no charge for parts or
labor (including diagnosis).
As the engine owner, you are responsible to perform all the required maintenance listed in your owner’s manual. New Holland will not deny an
emission warranty claim solely because you have no record of maintenance; however, a claim may be denied if your failure to perform
maintenance resulted in the failure of a warranted part. Receipts covering regular maintenance should be retained in the event of questions and
these receipts should be passed on to each subsequent owner of the engine.
It is recommended replacement parts used for maintenance or repairs be New Holland Service Parts to maintain the quality originally designed
into your emission certified engine. The use of non-New Holland parts does not invalidate the warranty on other components unless the use of
such parts causes damage to warranted parts.
New Holland wishes to assure the emission control systems warranty is being properly administered. If you believe you have not received the
service entitled to under this warranty, you should contact the nearest New Holland Branch Office for assistance. The address and phone
number of each Branch Office is in your vehicle owner’s manual. If additional assistance or information is needed, contact:
Service Department
New Holland North America, Inc.
500 Diller Avenue
New Holland, PA 17557
[phone]
Please note that the Emission Warranty does not cover:
1. Systems and parts that were not first installed on the new equipment or engine as original equipment by New Holland.
2. Part malfunctions caused by abuse, misuse, improper adjustment, modification, alteration, tampering, disconnection, improper or
inadequate maintenance, or use of non-recommended fuels and lubricating oils.
3. Accident caused damage, acts of nature, or other events beyond New Holland’s control.
4. Replacement of expendable items made in connection with scheduled maintenance.
5. Parts requiring replacement, inspection or adjustment maintenance intervals for reasons other than being defective.
6. Parts which are not New Holland Service Parts.
7. Loss of time, inconvenience, loss of use of equipment/engine or commercial loss.
8. Equipment with altered or disconnected hourmeter where the hours cannot be determined.
9. Equipment normally operated outside the United States.

CALIFORNIA EMISSION CONTROL WARRANTY STATEMENT
Your Warranty Rights and Obligations
The California Air Resources Board and New Holland are pleased to explain the emission control system warranty on your engine. In California,
new 1997 and later heavy-duty off-road engines from 100 to 150 HP must be designed, built, and equipped to meet the State’s stringent anti-smog
standards. New Holland must warrant the emission control system on your engine for the periods of time listed below, provided there has been no
abuse, neglect, or improper maintenance of your engine.
Your emission control system includes parts such as the fuel injection system and the air induction system.
Where a warrantable condition exists, New Holland will repair your heavy-duty off-road engine at no cost to you, including diagnosis, parts, and labor.
Manufacturer’s Warranty Coverage:
The 1997 and later heavy-duty off-road engines are warranted from the original date of delivery for five years or 3,000 hours of operation,
whichever occurs first. If any emission-related part on your engine is defective, the part will be repaired or replaced by New Holland.
Owner’s Warranty Responsibilities:
DAs the heavy-duty off-road engine owner, you are responsible for the performance of the required maintenance listed in your owner’s
manual. New Holland recommends that you retain all receipts covering maintenance on your heavy-duty off-road engine, but New Holland
cannot deny warranty solely for the lack of receipts or for your failure to ensure the performance of all scheduled maintenance.
DAs the heavy-duty off-road engine owner, you should, however, be aware that New Holland may deny you warranty coverage if your
heavy-duty off-road engine or a part has failed due to abuse, neglect, improper maintenance, or unapproved modifications.
DYour engine is designed to operate on commercially available diesel fuel only. Use of any other fuel may result in your engine no longer
operating in compliance with California’ s emissions requirements.
DYou are responsible for initiating the warranty process. The ARB suggests that you present your heavy-duty off-road engine to a New
Holland dealer as soon as a problem exists. The warranty repairs should be completed by the dealer as expeditiously as possible.
If you have questions regarding your warranty rights and responsibilities, you should contact your Branch Office at the address and phone number
listed on the Owner Assistance page of your equipments operator manual.
DPrior to the expiration of the warranty, you must give notice of any failure of an emission control warranted part. Such notice must be given to
New Holland or an authorized dealer, and you must deliver the engine to the repair location.
DYou, the owner, are responsible for incidental costs incurred by yourself or your employees as a result of a warrantable failure. Examples of
such costs are communication expenses, meals and lodging.
DThe owner is responsible for any business costs or losses, any “downtime” expenses and any “cargo” damage which result from the failure
of a warranted part. New Holland is not responsible for other incidental or consequential damages, including but not limited to fines, theft,
vandalism or collisions.
Parts covered:
This emission control system warranty applies to the following emission control parts.
Fuel Injection Pump
Fuel Injectors
Turbocharger
Intake Manifold
Exhaust Manifold
Boost Pressure Tubing-connection to Aneroid Device ON F.I.P.
Any replacement part, equivalent in performance and durability, may be used in the performance of any maintenance or repairs and must be
provided without charge to the owner. The use of these parts does not reduce the warranty obligations of New Holland. However, New Holland
recommends the use of new, genuine New Holland service parts or New Holland approved rebuilt parts and assemblies. New Holland also
recommends that the engine be serviced by a New Holland authorized dealer.
New Holland Responsibilities
Warranty work will be provided at no charge to the owner at any authorized dealer, using new genuine New Holland service parts or New Holland
approved rebuilt parts or assemblies..
The owner will not be charged for diagnostic labor which leads to the determination that a warranted part is defective, if the diagnostic work was
performed at a warranty station.
New Holland is liable for damages to other engine components caused by the failure under warranty of any warranted part.
Warranty Limitations
New Holland is not responsible for failures resulting from abuse or neglect by owner or operator.
New Holland warrants to the ultimate purchaser and each subsequent purchaser that the engine is designed, built, and equipped so as to conform
with all applicable regulations adopted by the Air Resources Board, and that it is free from defects in materials and workmanship which cause the
failure of a warranted part.
Any warranted part which is not scheduled for replacement as required maintenance, or which is scheduled only for regular inspection to the effect
of “repair or replace as necessary” is warranted for the warranty period.
Any warranted part which is scheduled for replacement as required maintenance is warranted for the period of time prior to the first scheduled
replacement point for that part.
New Holland is liable for damages to other engine components caused by the failure under warranty of any warranted part.

TO THE USER
GENERAL
This Use and Maintenance Manual provides a guide
for the user with regard to running--in, use and
maintenance of the tractor.
Read this manual carefully and keep in a convenient
place for future reference. Do not hesitate to contact
your local dealer for any questions concerning the
tractor. The dealer can provide skilled personnel,
trained by the Manufacturer, original spare parts and
all tools and equipment necessary for your service
requirements.
The tractor is designed as a power generator and
drive--propulsion unit for use in normal and traditional
agricultural conditions.
The tractor is also designed to provide maximum
performance, economic running and easy use over a
wide range of operations. Prior to delivery, all
machines are carefully inspected (by both the
Manufacturer and your local authorised dealer), to
make sure that they reach the user in perfect
condition. To maintain the tractor in this condition and
ensure trouble--free operation, the routine
maintenance described in Section 3 of this manual
must be carried out at the specified intervals.
CLEANING THE TRACTOR
Your tractor is an advanced machine, fitted with an
electro--hydraulic control system. Care should be
taken when cleaning the tractor, especially if a
pressurised water cleaner is used.
•Never stand too close to the tractor or direct the
water jet on electrical components, seals or
intake openings, etc.
•Never direct jets of cold water at the hot engine
or exhaust. See also Section 3
(Recommendations for bodywork maintenance).
SAFETY
Safety precautions for the operator and bystanders
are shown on pages vii to xiii inclusive. Read the
safety instructions and follow recommendations and
hints before starting to use the tractor.
SERVICE AFTER THE FIRST 50 HOURS OF
WORK
The operations required for the first service are
shown at the end of the Manual, immediately prior to
the index.
After the first 50 hours of use, return to the dealer with
your tractor and this Manual in order to carry out the
Manufacturer’s checks and to fill in the certificates
included on pages (1 and 3). The first sheet (page 1)
must be compiled on completion of the service and
held by the dealer. The second sheet (page 3) must
be kept in the Manual for documentation and
reference purposes. Check that both copies are
signed by both yourself and the dealer.
SPARE PARTS
“Non--original” spare parts have not been tested or
authorised by the Manufacturer. Instalment and/or
use of such products may adversely affect the
tractor’s design specifications, thereby
compromising operational safety. The manufacturer
cannot be held responsible for any damage resulting
from the use of “non--original” spare parts.
No modifications may be made to the tractor without
written authorisation from the Manufacturer.
WARRANTY
The tractor is guaranteed in accordance with current
legislation in your country and in line with contractual
agreements reached with the dealer at the time of
sale. However, the warranty is no longer valid if the
rules and instructions for the use and maintenance
of the tractor, described in this Manual, are not
observe

TRACTOR IDENTIFICATION

IMPORTANT ECOLOGICAL
CONSIDERATIONS
Soil, air and water are essential elements for
agriculture and for life in general. If local legislation
does not control the treatment of certain substances,
the production of which is necessitated by advanced
technologies, products derived from chemical and
petrochemical products must be used and disposed
of according to the rules of common sense.
The following recommendations may be of help:
•Find out what the relevant legislation stipulates.
•Ask your suppliers of lubricants, oils, fuels,
anti--freeze, detergents, etc., for information on the
effects of these products on humans and the
environment and for instructions concerning their
use, storage and disposal. In many cases, local
agricultural consultants will be able to provide
assistance.
SUGGESTIONS
1. Avoid using unsuitable, pressurised filling
systems or fuel cans when filling tanks, as these
may cause considerable spillage and leakage of
liquids.
2. As a general rule, do not allow liquid fuels,
lubricants, acids, solvents, etc., to come into
contact with the skin. The majority of these
products contain substances that are potential
health hazards.
3. Modern lubricants contain additives. Do not burn
contaminated fuel oils and/or oils used in
conventional heating systems.
4. Avoid spillage when transferring used engine
cooling liquids, engine and transmission
lubricants, hydraulic oils, brake fluids, etc..
Never mix used brake oil with fuel oil, or fuel oil
with lubricants. Store safely until suitable
disposal can be arranged according to national
legislation or local regulations.
5. Modern anti--freeze liquids and solutions, e.g.:
anti--freeze and other additives, must be
replaced every two years. They must not be left
to be absorbed into the ground, but must be
collected and disposed of in a suitable manner.
6. Do not open the air conditioning systems to carry
out work. These systems contain gas which must
not be released into the atmosphere. Contact your
dealer or specialised personnel, who are equipped
with the appropriate equipment and are authorised
to re--fill the system.
7. Any leakage or defect in the engine cooling or
hydraulic systems must be repaired immediately.
8. Do not increase the pressure in pressurised
systems, as this may cause component parts to
burst.
9. When welding, make sure that hoses are
properly protected as sparks or molten material
may puncture or weaken the tubes and sleeves,
resulting in leakage of oil, cooling liquid, etc..
10. Do not adjust the setting of the fuel delivery
system as this will alter the emission of exhaust
fumes.
NOTE: The engines installed on the tractors comply
with anti--pollution legislation.

SAFETY NORMS
v
WORKING SAFELY
GENERAL
During the manufacturing of this tractor, every step
has been taken to ensure safe operation. However,
the best way to avoid accidents is to exercise caution
at all times. Once the accident has already happened
it is too late to remember what steps should have
been taken.
Read this manual carefully before starting, using,
carrying out maintenance, refuelling or performing
any other type of operation on the tractor.
The time spent reading this manual will allow you to get
to know your tractor, thereby saving time and effort..
This will also help prevent accidents from taking place.
Read all the safety decals on the machine and follow
the instructions thereon before starting, operating,
refuelling or carrying out maintenance on the ma-
chine. Promptly replace any decals that are dam-
aged, lost or illegible.
Clean the decals if they are covered by mud or de-
bris.
Remember that the tractor is exclusively designed
for agricultural use. Any other use will require prior
authorisation from NEW HOLLAND.
It is advisable to keep a first aid kit on hand.
The tractor must only be used by responsible per-
sonnel, trained in tractor use and authorised to oper-
ate the machine.
Do not alter the injection system calibration in an at-
tempt to increase maximum engine speed.
Do not wear loose clothing that may be trapped in mov-
ing parts.
Check that all rotating parts connected to the power
take--off are correctly protected.

SAFETY NORMS
vi
Do not alter the calibration of the pressure relief
valves in the various hydraulic circuits (hydrostatic
steering, hydraulic lift, auxiliary distributors, etc.).
Avoid using the tractor in unsuitable physical condi-
tions, stop work instead.
Enter and leave the tractor using the steps and
handles provided. Keep these fittings free of mud
and debris.
Always operate with the roll bar correctly and secure-
ly fitted on the tractor: periodically check that the fit-
tings are not loose and that all parts of the structure
are free from any damage and deformation. Do not
modify the roll bar by welding parts, drilling holes,
etc., as this could adversely affect the rigidity of the
structure.
STARTING THE TRACTOR
Before starting the engine, check that the handbrake
is on and that the gears and power take--off are dis-
engaged, even if the tractor is fitted with a start--up
safety device. Never disconnect the start--up safety
switch. If the switch does not work correctly, contact
your local dealer for eventual repair operations.
Before starting the engine, make sure that all at-
tached implements are lowered to the ground.
Before starting the engine, check that all covers and
guards are correctly in position (roll bar, engine side
panels, power take--off guard, front axle trans-
mission shaft cover, etc.).
Never start or maneuver the tractor unless
seated in the driving position.
Before moving the tractor, always check that the
area is free of people or obstacles.
Never run the engine in a closed space without ensur-
ing adequate ventilation. Exhaust fumes are damaging
to the health and can be lethal .
