12. 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

(1) Clutch cover (4) Release bearing (7) Clutch release lever (10) Flywheel
(2) Clutch disc (5) Release bearing hub (8) Clutch lever shaft (11) Diaphragm boss
(3) Diaphragm spring (6) Clutch main shaft (9) Pressure plate
The clutch assembly bolts to the flywheel and the clutch main shaft (6) connects to the diaphragm boss (11) in the
clutch assembly with splines. The pressure plate will compress the clutch by the force of the diaphragm spring (3).
When the engine is running, the flywheel, clutch assembly, clutch disc and clutch main shaft rotate together. When the
operator depresses clutch pedal, the clutch lever (7) pushes the release bearing hub (5) toward the flywheel. Then,
the release bearing (4) installed to the end of the release bearing hub pushes the center of the diaphragm spring (3)
of the clutch assembly. As a result, the edge of the diaphragm is separated from the pressure plate (9) which is then
separated from the clutch disc (2).As the clutch disc in between the flywheel and pressure plate loses contact, the
clutch disc and diaphragm stop but the flywheel and clutch cover continue to turn. Therefore, the rotating force of the
flywheel is not transferred to the clutch main shaft, resulting in the interruption of power from the engine.
