Hazardous chemicals

If you are exposed to or come in contact with hazardous chemicals you can be seriously injured. The fluids, lubricants,

paints, adhesives, coolant, etc. required for the function of your machine can be hazardous. They may be attractive

and harmful to domestic animals as well as humans.

Material Safety Data Sheets (MSDS) provide information about the chemical substances within a product, safe han-

dling and storage procedures, first aid measures and procedures to be taken in the event of a spill or accidental

release. MSDS are available from your dealer.

Before you service your machine check the MSDS for each lubricant, fluid, etc. used in this machine. This information

indicates the associated risks and will help you service the machine safely. Follow the information in the MSDS, on

manufacturer containers, as well as the information in this manual when servicing the machine.

Dispose of all fluids, filters, and containers in an environmentally safe manner according to local laws and regulations.

Check with local environmental and recycling centers or your dealer for correct disposal information.

Store fluids and filters in accordance with local laws and regulations. Use only appropriate containers for the storage

of chemicals or petrochemical substances.

Keep out of reach or children or other unauthorized persons.

Additional precautions are required for applied chemicals. Obtain complete information from the manufacturer or

distributor of the chemicals before using them.

Utility safety

Make sure that the machine has sufficient clearance to pass in all directions. Pay special attention to overhead power

lines and hanging obstacles. High voltage lines may require significant clearance for safety. Contact local authorities

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

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.

shaft rotation

The machine is equipped with a main drive gearbox

that allows it to be installed on tractors with both clock-

wise and counterclockwise rotating front Power Take-

Off (PTO) shafts. By default, the unit is shipped and

configured for use with tractors that have a counter-

clockwise rotating PTO shaft, as depicted in Figure 1.

The direction of rotation is determined by looking to-

ward the tractor PTO shaft. For tractors with clockwise

rotating front PTO shafts, the gearbox will need to be re-

moved and converted before the PTO shaft is installed.
