INTRODUCTION Safety rules - Personal safety Precautionary statements A careful operator is the best operator. Most accidents can be avoided by observing certain precautions. To help prevent accidents, read the following precautions before operating this equipment. Equipment should be operated only by those who are responsible and instructed to do so. Carefully review the procedures given in this manual with all operators. It is important that all operators be familiar with and follow safety precautions. 1. Always disengage the drive, lock the tractor brakes, and shut off the tractor engine before: • Leaving the seat. • Lubricating. • Cleaning or unplugging any part of the machine. • Adjusting the machine. 2. Always lower the header to the ground or engage the transport stops when parking. 3. Always use the header transport stops and spring-loaded tongue safety lock when transporting the machine. 4. Never work under a raised header unless it is securely locked with the header transport stops 5. Always block the wheels before working on or under the machine. 6. Do not start the machine until you know that everyone is clear of the machine and have made sure no tools are lying on it. 7. Keep all shields in place. Never work around the machine in loose clothing that could catch in a moving part. 8. Do not modify any shields or operate the machine with any shields removed. 9. Always use adequate lights and safety warning devices when transporting the machine on public roads or after dark. Check with your local law enforcement agencies for speciﬁc requirements. 10. Long exposure to loud noise can damage your hearing. Wear a suitable hearing protection device such as ear- muffs or ear plugs if you are exposed to uncomfortable noise levels. 11.

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-conditioning 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 47851907 11/03/2015 6
