INTRODUCTION
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 NEW HOLLAND 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.

INTRODUCTION
Safety rules - Personal safety
Carefully study these precautions, and those included in the external attachment operators
manual, and insist that they be followed by those working with and for you.
1. Thoroughly read and understand this manual and the attachment Operator’s Manual before operating this or any
other equipment.
2. Be sure all people and pets are clear of the machine before starting. Sound the horn, if equipped, three times
before starting engine.
3. Only the operator should be on the machine when in operation. Never allow anyone to climb on to the machine
while it is in motion. If the machine is equipped with an Instructors Seat, this must only be used for training
purposes. Passengers must not be allowed to use the Instructors Seat.
4. Keep all shields in place. Never work around the machine or any of the attachments while wearing loose clothing
that might catch on moving parts.
5. Observe the following precautions whenever lubricating the machine or making adjustments.
• Disengage all clutching levers or switches.
• Lower the attachment, if equipped, to the ground or raise the attachment completely and engage the cylinder
safety locks. Completing these actions will prevent the attachment from lowering unexpectedly.
• Engage the parking brake.
• Shut off the engine and remove the key.
• Wait for all machine movement to stop before leaving the operators platform.
6. Always keep the machine in gear while travelling downhill.
7. The machine should always be equipped with sufficient front or rear axle weight for safe operation.
8. Under some field conditions, more weight may be required at the front or rear axle for adequate stability. This is
especially important when operating in hilly conditions or/when using heavy attachments.
9. Always lower the attachment, shut off the engine, set the parking brake, engage the transmission gears, remove
the key and wait for all machine movement to stop before leaving the operators platform.
10. If the attachment or machine should become obstructed or plugged; set the parking brake, shut off the engine
and remove the key, engage the transmission gears, wait for all machine or attachment motion to come to a stop,
before leaving the operators platform to removing the obstruction or plug.
11. Never disconnect or make any adjustments to the hydraulic system unless the machine and/or the attachment is
lowered to the ground or the safety lock(s) is in the engaged position.
12. Use of the flashing lights is highly recommended when operating on a public road.
13. When transporting on a road or highway, use accessory lights and devices for adequate warning to the opera-
tors of other vehicles. In this regard, check local government regulations. Various safety lights and devices are
available from your NEW HOLLAND dealer.
14. Practice safety 365 days a year.
15. Keep all your equipment in safe operating condition.
16. Keep all guards and safety devices in place.
17. Always set the parking brake, shut off the engine and remove the key, engage the transmission gears, wait for all
machine or attachment motion to come to a stop, before leaving the operators platform to service the machine
and attachment.
18. Remember: A careful operator is the best insurance against an accident.
19. Extreme care should be taken in keeping hands and clothing away from moving parts.

light oil. Make sure both surfaces are aligned properly.
Torque the fitting to specified torque listed throughout the
repair manual.
NOTICE: If the fitting surfaces are not properly cleaned,
the O-ring will not seal properly. If the fitting surfaces are
not properly aligned, the fittings may be damaged and will
not seal properly.
NOTICE: Always use genuine factory replacement oils
and filters to ensure proper lubrication and filtration of en-
gine and hydraulic system oils.

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

INTRODUCTION
Basic instructions - Chain wear tables - Roller chains
Chain wear
The individual joints in a roller chain articulate as they en-
ter and leave the sprockets. This articulation results in
wear on the pins and bushings. Material that is worn away
from these surfaces will cause the chain to gradually elon-
gate. Chains do not stretch. Material is worn from pin and
bushing.
Critical dimensions of the chain are as follows:
• (1) 2X pitch
• (2) Wear plus 2X pitch
• (3) Elongation due to pin and bushing wear
96091478 1
Elongation is normal and may be minimized by proper
lubrication and drive maintenance. The rate of wear is
dependent upon: the relationship between the load and
the amount of bearing area between pin and bushing, the
material and surface condition of the bearing surfaces, the
adequacy of lubrication, and the frequency and degree
of articulation between pins and bushings. The latter is
determined by the quantity of sprockets in the drive, their
speeds, the number of teeth and the length of the chain
in pitches.
An accurate wear measurement (1) can be made by us-
ing the above illustration. Measure as closely as possible
from the center of one pin to the center of another. The
more pitches (pins) contained within the measurement in-
crease the accuracy. If the measured value exceeds the
nominal by more than the allowable percentage the chain
should be replaced. The maximum allowable wear elon-
gation is approximately 3 % for most industrial applica-
tions, based upon sprocket design. The allowable chain
wear in percent can be calculated using the relationship:
200/ (N), where (N) is the number of teeth in the large
sprocket. This relationship is often useful since the nor-
mal maximum allowable chain wear elongation of 3 % is
valid only up to 67 teeth in the large sprocket. In drives
having fixed center distances, chains running in parallel
or where smoother operation is required, wear should be
limited to approximately 1.5 %.
For example, if 12 pitches (12 pins) of a #80 chain were
measured and the result was 313.944 mm (12.360 in)
or greater (using 3 % as the maximum allowable wear),
the chain should be replaced. Anything less than
313.944 mm (12.360 in) would still be acceptable by
most industrial standards.
