IMPORTANT INFORMATION
All repair and maintenance works listed in this manual must be carried out only by staff belonging to the NEW HOL-
LAND Service network, strictly complying with the instructions given and using, whenever required, the special tools.
Anyone who carries out the above operations without complying with the prescriptions shall be responsible for the
subsequent damages.
The manufacturer and all the organizations of its distribution chain, including - without limitation - national, regional or
local dealers, reject any responsibility for damages due to the anomalous behavior of parts and/or components not
approved by the manufacturer himself, including those used for the servicing or repair of the product manufactured
or marketed by the Manufacturer. In any case, no warranty is given or attributed on the product manufactured or
marketed by the Manufacturer in case of damages due to an anomalous behavior of parts and/or components not
approved by the Manufacturer.
No reproduction, though partial of text and illustrations allowed.

INTRODUCTION
Foreword - How to use and navigate through this manual
This manual has been produced by a new technical information system. This new system is designed to deliver
technical information electronically through web delivery (eTIM), DVD, and paper manuals. A coding system called
SAP has been developed to link the technical information to other Product Support functions, e.g., Warranty.
Technical information is written to support the maintenance and service of the functions or systems on a customer's
machine. When a customer has a concern on their machine it is usually because a function or system on their ma-
chine is not working at all, is not working efficiently, or is not responding correctly to their commands. When you refer
to the technical information in this manual to resolve that customer's concern, you will find all the information classified
using the SAP coding, according to the functions or systems on that machine. Once you have located the technical
information for that function or system, you will then find all the mechanical, electrical or hydraulic devices, compo-
nents, assemblies, and sub assemblies for that function or system. You will also find all the types of information that
have been written for that function or system: the technical data (specifications), the functional data (how it works),
the diagnostic data (fault codes and troubleshooting), and the service data (remove, install adjust, etc.).
By integrating SAP coding into technical information, you will be able to search and retrieve just the right piece of
technical information you need to resolve that customer's concern on his machine. This is made possible by attaching
3 categories to each piece of technical information during the authoring process.
The first category is the Location, the second category is the Information Type and the third category is the Product:
• LOCATION - the component or function on the machine, that the piece of technical information is going to describe
(e.g., Fuel tank).
• INFORMATION TYPE - the piece of technical information that has been written for a particular component or func-
tion on the machine (e.g., Capacity would be a type of Technical Data describing the amount of fuel held by the fuel
tank).
• PRODUCT - the model for which the piece of technical information is written.
Every piece of technical information will have those three categories attached to it. You will be able to use any combi-
nation of those categories to find the right piece of technical information you need to resolve that customer's concern
on their machine.
That information could be:
• the procedure for how to remove the cylinder head
• a table of specifications for a hydraulic pump
• a fault code
• a troubleshooting table
• a special tool

INTRODUCTION
ACCIDENT PREVENTION
WARNING
Avoid injury! Always do the following before lubricating, maintaining, or servicing the machine.
1. Disengage all drives.
2. Engage parking brake.
3. Lower all attachments to the ground, or raise and engage all safety locks.
4. Shut off engine.
5. Remove key from key switch.
6. Switch off battery key, if installed.
7. Wait for all machine movement to stop.
Failure to comply could result in death or serious injury.
W0047A
Most accidents or injuries that occur in workshops are the result of non compliance to simple and fundamental safety
principles. For this reason, IN MOST CASES THESE ACCIDENTS CAN BE AVOIDED by applying the fundamental
safety principles, acting with the necessary caution and care.
Accidents may occur with all types of machine, regardless of how well the machine in question was designed and
built.
SAFETY REQUIREMENTS FOR FLUID POWER SYSTEMS AND COMPONENTS - HY-
DRAULICS (EUROPEAN STANDARD EN982)
• Flexible hose assemblies must not be constructed from hoses which have been previously used as part of a hose
assembly.
• Do not weld hydraulic pipes: when flexible hoses or piping are damaged, replace them immediately.
• It is forbidden to modify a hydraulic accumulator by machining, welding or any other way.
• Before removing hydraulic accumulators for servicing, the liquid pressure in the accumulators must be reduced to
zero.
• Pressure check on hydraulic accumulators must be carried out by a method recommended by the accumulator
manufacturer.
• Take care not to exceed the maximum allowed pressure of the accumulator. After any check or adjustment, check
for leakages or gas in the hoses or pipes.
SAFETY RULES
General guidelines
• Carefully follow specified repair and maintenance procedures.
• When appropriate, use P.P.E (Personal Protective Equipment)
• Do not wear rings, wristwatches, jewellery, unbuttoned or loose articles of clothing such as: ties, torn clothing,
scarves, open jackets or shirts with open zips that may remain entangled in moving parts. It is advised to wear
approved safety clothing, e.g.: non-slip footwear, gloves, safety goggles, helmets, etc.
• Do not carry out repair operations with someone sitting in the driver's seat, unless the person is a trained technician
who is assisting with the operation in question.
• Do not operate the machine or use any of the implements from different positions, other than the driver's seat.
• Do not carry out operations on the machine with the engine running, unless specifically indicated.
• Bring all hydraulic cylinders to the home positions (down, retracted, etc.) before engine shut down.
• Stop the engine and check that the hydraulic circuits are pressure-free before removing caps, covers, valves, etc.
• All repair and maintenance operations must be carried out using extreme care and attention.
• Service steps and platforms used in the workshop or elsewhere should be built according to the applicable stan-
dards and legislation.
• Disconnect the power take off (p.t.o). and label the controls to indicate that the machine is being serviced. Any
parts that are to be raises must be locked in position.
