Volume 1/2 - Operation

GENERAL
This manual has been prepared to assist you in the correct procedure for running in, driving, operating, adjusting
and maintaining your new machine.
This machine has been designed and built to give maximum performance, economy and ease of operation under
a wide variety of crops and conditions.
Prior to delivery, your machine was carefully inspected both at the factory and by your dealer to ensure that it
reaches you in optimum condition. To maintain this condition and ensure trouble-free operation it is important
that routine services, as specified in this manual, are carried out at the recommended intervals.
Before attempting to drive or operate your machine, read this manual carefully (especially the chapter covering
the Safety Precautions) and keep it in a convenient place for future reference.
’’Left” and ’’right” used throughout this manual are determined from the rear, facing in the direction of travel of
the machine during operation.
If at any time you require advice concerning your machine, do not hesitate to contact your authorised dealer.
He has factory-trained personnel, genuine service parts and the necessary equipment to carry out your service
requirements.
IMPORTANT:
This machine has been designed and built according to the European Directive 98/37/EC.
Always use genuine New Holland Service parts or parts matching at least the same quality, reliability and
functionality as the equivalent original Service Parts when servicing and repairing your machine and do not
modify your machine without a written permission of the manufacturer. Failure to do so will void the responsibility
of the manufacturer.
An EC Declaration of Confirmity is separately delivered with your machine.
Store this EC Declaration into the storage space for your Operator’s Manual
(refer to section 2 – Controls, Instruments and Operation).
The maximum road speed of your machine is limited electronically. Do not try to change it.
Check local road legislation before driving the machine on public roads.
When operating interchangeable New Holland built equipment, ensure the equipment is CE approved.
As this publication is distributed throughout our international network, the equipment illustrated, either as
standard or as an accessory, may vary according to the country in which the equipment is to be used. Low cost
configurations, as chosen by the customer, may deviate from the specifications given.
Several figures in this manual show the safety guarding or the additional guards, legally required by certain
countries, open or removed to illustrate better a particular feature or adjustment. The machine must not be used
in this condition. For your own safety, ensure that all guards are closed or replaced before operating the machine.

OWNER ASSISTANCE
We at New Holland and your New Holland dealer want you to be completely satisfied with your investment.
Normally your dealer’s Service Department will handle any problems with your equipment. Sometimes, however,
misunderstanding can occur. If your problem has not been handled to your satisfaction, we suggest contacting
the owner or General Manager of the dealership, explaining the problem, and requesting assistance. When
additional assistance is needed, your dealer has direct access to our branch office.
COMPANY POLICY
Company policy, which is one of continuous improvement, reserves the right to make changes in design and
specification at any time without notice and without obligation to modify units previously built.
All data given in this book is subject to production variations. Dimensions and weights are approximate only and
the illustrations do not necessarily show the machine in standard condition. For exact information about any
particular machine please consult your Dealer.
ACCESSORIES AND OPTIONS
Your machine has been designed to operate in a wide variety of crops and conditions. Nevertheless additional
equipment may, in certain cases, be required to improve the machine performance. A list of this additional
equipment is given in the ’’Accessories” section in this manual.
PARTS AND ACCESSORIES
Genuine New Holland parts and accessories have been specifically designed for New Holland machines.
We would like to point out that ’’nongenuine” parts and accessories have not been examined and released by
New Holland. The installation and/or use of such products could have negative effects upon the design
characteristics of your machine and thereby affect its safety. New Holland is not liable for any damage caused
by the use of ’’nongenuine” parts and accessories.
Rely on your authorised dealer to supply you with genuine New Holland parts only. These parts are covered by
our warranty and will give you the best performance.
When ordering service parts, always quote the model and serial number, as well as the year of manufacture
printed on the manufacturer’s identification plate (refer to chapter General Information).

LUBRICANTS
Your dealer sells a selection of specially formulated lubricants based on own engineering specifications.
Recommended lubricants for your machine are listed on the inside back cover of this manual.
WARRANTY
Your machine is warranted according to legal rights in your country and the contractual agreement with the selling
dealer. No warranty shall, however, apply if the machine has not been used, adjusted and maintained according
to the instructions given in this Operator’s Manual.
It is prohibited to carry out any modifications to the machine unless specifically authorised, in writing, by a New
Holland representative.
CLEANING YOUR MACHINE
Your machine is a state-of-the-art machine with sophisticated, electronic controls. Even though every precaution
has been taken to safeguard electronic components and connections, the pressure generated by some pressure
washers is such that complete protection against water ingress cannot be guaranteed.
When using a high pressure washer, do not stand too close to the machine and avoid directing the jet at electronic
components, electrical connections, breathers, seals, filler caps, etc.
IMPORTANT ENVIRONMENTAL CONSIDERATIONS
Soil, air and water are vital factors of agriculture and of life in general. Where legislation does not yet rule the
treatment of some of the substances, which are required by advanced technology, common sense should govern
the use and the disposal of the products of a chemical and a petrochemical nature.
The following are recommendations, which may be of assistance:
Become acquainted with and respect the relative legislation applicable in your country.
Where no legislation exists, obtain information from suppliers of oils, fuels, antifreeze, cleaning agents, etc. for
their effect on man and nature and for safe ways of storage, usage and disposal. Agricultural consultants will,
in many cases, be able to help you as well.

HELPFUL HINTS
Avoid filling fuel tanks using jerrycans or inappropriate pressurized fuel delivery systems which may cause
considerable spillage.
In general, avoid skin contact with all oils, acids, solvents, etc. Most of them contain substances which can be
harmful to your health.
Use biodegradable oils for chain lubrication where oils cannot be recuperated. In many countries rapeseed oils
or other agro-based lubricants have become available.
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, fuels or coolant mixtures with lubricants. Store them safely until they can
be disposed of in a proper way to comply with local legislation and available resources. They should not be
allowed to get into the soil but should be collected and disposed of safely.
Do not open the air-conditioning system yourself; it contains gases, which should not be released into the air.
Your dealer has a special extractor for this purpose and will have to do the recharging of the system anyway.
Repair any leaks or defects in the engine cooling or the hydraulic system immediately.
Do not increase the pressure in a pressurized circuit as this may lead to bursting of the components.
Protect hoses during welding as penetrating weld splatter may burn a hole or weaken them, causing the loss
of oils, coolant, etc.
Battery recycling
Batteries and electric accumulators contain various components which can damage the environment if they are
not properly recycled after usage. New Holland strongly recommends that you return all used batteries (starting
batteries and small ”dry” batteries which may be used in electric or electronic systems) to your New Holland
dealer who will ensure proper disposal or recycling. In certain countries this is a legal requirement.
