GENERAL INFORMATION AND SAFETY

TO THE OWNER

GENERAL

This Manual has been prepared to assist you in the correct procedure for running--in, driving and operating and for the maintenance of your new tractor. Your tractor, which was designed to power and propel itself, is intended for use in normal and customary agricultural applications.

Read this Manual carefully and keep it in a convenient place for future references. If at any time you require advice concerning your tractor, do not hesitate to contact your Authorised Dealer. He has company trained personnel, genuine manufacturers’ parts and the necessary equipment to carry out all your service requirements.

Your tractor has been designed and built to give maximum performance, economy and ease of operation under a wide variety of operating conditions. Prior to delivery, the tractor was carefully inspected, both at the factory and by your dealer to ensure that it reaches you in optimum condition. To maintain this condition and trouble--free operation, it is important that the routine services, as specified in Section 4 of this manual, are carried out at the recommended intervals.

CLEANING THE TRACTOR

When cleaning the tractor, particularly if using a high pressure washing machine. precaution has to be taken to safeguard electrical / electronic components and connections. The pressure generated by some of these machines is such that complete protection against water ingress cannot be guaranteed.

While washing the tractor, using a high pressure washing machine, do not stand too close to the tractor and avoid directing the jet at electrical connections, breathers, seals, filler caps, etc. Never direct a cold water jet at a hot engine or exhaust.

SAFETY

Pages 5 to 9 include the list of precautions to be observed to ensure your safety and the safety of others. Read the safety precautions and follow the advice offered before operating the tractor.

FIRST 50 HOUR SERVICE

After you have operated the tractor for 50 hours, take your tractor, together with warranty booklet to your dealer. He will then perform the manufacturer recommended 50 hour service and complete the service report. Ensure the completion of the coupon and signature of Service Manager/Dealer.

SERVICE PARTS

It should be pointed out that genuine parts have been examined and approved by the company. The installation and/or usage of ‘non-genuine’ products could have negative effects upon the design characteristics of your tractor and thereby affect it’s safety. The Company is not liable for any damage caused by the use of ‘non--genuine’ parts and accessories.

Only Genuine New Holland replacement parts should be used. The use of non-genuine parts may invalidate legal approvals associated with this product.

It is prohibited to carry out any modifications to the tractor unless specifically authorised, in writing, by the After Sales Service department of the Company.

ECOLOGY AND THE ENVIRONMENT

Soil, air and water are vital factors of agriculture and life in general. Where legislation does not yet rule the treatment of some of the substances which are required by advanced technology, common sense should govern the use and disposal of products of a chemical and petrochemical nature.

The following are recommendations which 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, cleaning agents, etc., with regard to their effect on man and nature and how to safely store, use and dispose off these substances.

HELPFUL HINTS

1. Avoid filling tanks using open containers or inappropriate pressurised fuel delivery systems which may cause excessive spillage.
2. In general, avoid skin contact with all fuels, oils, acids, solvents, etc. Most of them contain substances which can be harmful to your health. 3. Modern oils contain additives. Do not burn contaminated fuels and/or waste oils in ordinary heating systems. 4. 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 off in a proper way to comply with local legislation and available resources. 5. Modern coolant mixtures, i.e. antifreeze and other additives, should be replaced every two years. They should not be allowed to get into the soil but should be collected and disposed off safely. 6. Repair any leaks or defects in the engine cooling or hydraulic system immediately. 7. Do not increase the pressure in a pressurised circuit as this may lead to the component exploding. 8. Protect hoses during welding as penetrating weld splatter may burn a hole or weaken them, causing the loss of oils, coolant, etc.

DRIVING THE TRACTOR

1. Always sit in the driver’s seat while starting or driving the tractor.
2. When driving on public roads, have consideration for other road users. Pull in to the left side of the road occasionally to allow any following traffic to pass. Do not exceed the legal speed limit set for agricultural tractors.
3. Dip the tractor lights when meeting a vehicle at night. Make sure the lights are adjusted to prevent blinding the driver of an oncoming vehicle.
4. Reduce speed before turning or applying the brakes. Brake both wheels simultaneously when making an emergency stop. Ensure that both brake pedals are locked together when travelling at road speeds or when on public roads ensure correct operation of trailer brakes.
5. Use extreme caution and avoid hard application of the tractor brakes when towing heavy loads at road speeds.
6. Keep the tractor in the same gear when going downhill as would be used when going uphill. Do not coast or freewheel down hills. 7. Any towed vehicle whose total weight exceeds that of the towing tractor must be equipped with brakes for safe operation. 8. Never try to apply the differential lock when turning. When engaged, the differential lock will prevent the tractor from turning. 9. Always check overhead clearance, especially when transporting the tractor. Watch where you are going, especially at row ends, on roads and around trees and low overhanging obstacles. 10. To avoid overturns, drive the tractor with care and at speeds compatible with safety, especially when operating over rough ground, when crossing ditches or slopes and when turning corners. 11. Use extreme caution when operating on steep slopes. 12. If the tractor becomes stuck or the tyres are frozen to the ground, reverse the tractor out to prevent overturning.

OPERATING THE TRACTOR

1. Apply the parking brake, place the P.T.O. control in the ‘OFF’ position, the lift control lever in the down position, and the transmission levers in neutral before starting the tractor.
2. Do not start the engine or operate controls while standing beside the tractor. Always sit in the tractor seat when starting the engine or operating the controls.
3. Do not bypass the transmission neutral start switches. Consult your authorised dealer if your neutral start controls malfunction.
4. Use jump leads only in the recommended manner. Improper use can result in a tractor runaway on its own or causing damage to the battery.
5. Avoid accidental contact with the gear shift levers while the engine is running. Unexpected tractor movement can result from such contact.
6. Do not get off the tractor while it is in motion.
7. Before leaving the tractor, park the tractor on level ground, apply the parking brake, lower attached implements to the ground, disengage the P.T.O. and stop the engine.
8. Do not park the tractor on a steep incline.
9. Do not operate the tractor with parking brake applied 10. Do not run the tractor engine in an enclosed building without adequate ventilation. Exhaust fumes are toxic and can cause death. 11. Pull only from the pick-up hitch, swinging drawbar or the lower link drawbar in the lowered position. Use only a drawbar pin that locks in place. Pulling from the tractor rear axle or any point above the axle may cause the tractor to overturn. 12. Always select Position Control when attaching equipment and when transporting equipment. Be sure hydraulic couplers are properly mounted and will disconnect safely in case of accidental detachment of the implement. 13. If the front end of the tractor tends to rise when heavy implements are attached to the three--point hitch, install front end weights. Do not operate the tractor with a light front end. 14. Engage the clutch slowly when driving out of a ditch, gully or up a steep hillside. Disengage the clutch promptly if the front wheels rise off the ground. 15. Ensure any attached equipment or accessories are correctly installed, are approved for use with the tractor, do not overload the tractor and are operated and maintained in accordance with the instructions issued by the equipment or accessory manufacturer.

5. To prevent fire or explosion, keep open flames away from battery or cold weather starting aids. To prevent sparks which could cause explosion, use jumper cables according to instructions.
6. Hydraulic fluid and fuel oil in the injection system operate under high pressure. Escaping hydraulic fluid or fuel oil under pressure can penetrate the skin causing serious injury. Unqualified persons should not remove or attempt to adjust a pump, injector, nozzle or any other part of the fuel injection or hydraulic systems. Failure to follow these instructions can result in serious injury.

• Do not use your hand to check for leaks. Use a piece of cardboard or paper to search for leaks.
• Stop the engine and relieve pressure before connecting or disconnecting lines.
• Tighten all connections before starting the engine or pressurising lines.
• If fluid is injected into the skin obtain medical attention immediately or gangrene may result.

7. Do not modify or alter or permit anyone else to modify or alter the tractor or any of its components or any tractor function without first consulting an Authorised Dealer.
8. Continuous long term contact with used engine oil may cause skin cancer. Avoid prolonged contact with used engine oil. Wash skin promptly with soap and water.
9. Keep equipment clean and properly maintained.
   10. Dispose of all drained fluids and removed filters properly.
   11. Tractor wheels are very heavy. Handle with care and ensure, when stored, that they cannot topple and cause injury.

DIESEL FUEL

1. Under no circumstances should gasoline, alcohol or blended fuels be added to diesel fuel. These combinations can create an increased fire or explosive hazard. In a closed container such as a fuel tank these blends are more explosive than pure gasoline. Do not use these blends.
2. Never remove the fuel cap or refuel with the engine running or hot.
3. Do not smoke while refuelling the tractor or when standing near fuel. Keep any type of open flame away.
4. Do not fill the fuel tank to capacity. Fill only to the bottom of the filler neck to allow room for expansion.
5. Wipe up spilled fuel immediately. Always tighten the fuel tank cap securely.
6. If the original fuel tank cap is lost, replace it with an approved cap. A non--approved cap may not be safe.
7. Never use fuel for cleaning purpose.

FUEL SAVING TIPS FOR OPTIMUM OUTPUT

Proper maintenance of Tractor reduces fuel consumption to a greater extent.

1. Store fuel in properly cleaned, rust and contamination free containers.
2. Always fill the tank at the end of each day to reduce overnight condensation of moisture in the air, in turn to avoid damage to the fuel system.
3. Fuel filters should be replaced as per recommended time schedule as the filtering capacity is not retained after this specified time. It may allow harmful contamination and damage the fuel injection system. Follow the service schedule for draining the water from the filters and cleaning the feed pump filter.
4. Always use genuine fuel filters available from your Authorised Dealers.
5. Stop diesel leakage, if any, immediately.
6. Dirt particles entering the engine causes early wear of liners and piston rings, resulting in loss of power, engine oil & fuel consumption. Clean the pre--cleaner bowl daily and change the air cleaner oil as mentioned in service schedule. Ensure that there is no leakage through hoses and the air cleaner bowl seal is in good condition, keep hose clamps tight.
7. Check the Radiator coolant level daily and top--up with clean water only. Radiator fins should always be kept clean. Should it be necessary to replace radiator cap, use only genuine cap of the specified pressure. Never try to remove the thermostat. Check and adjust fan belt tension regularly. Ignoring these, will result in engine over heating and heavy diesel consumption. 8. Follow the running--in procedure given in this manual for optimum performance of your tractor. 9. Do not run the engine in idle condition for more than two minutes. It may result in wastage of fuel. 10. Do not rest your foot on clutch pedal, as this will cause clutch slippage, loss of engine power and increased fuel consumption. Maintain the specified cluctch pedal free play. 11. Always drive the tractor in proper gear. 12. Use a lower gear while driving down a slope and use brakes sparingly. 13. Maintain proper tyre pressures for field work as well as for roadwork. Refer the tyre pressure chart given in this manual. Worn out tyres causes wheel slippage and waste fuel. Re--tread or replace the tyres if they are badly worn out. Adhere to tyre ballasting as and when required to reduce wheel slippage and fuel consumption. 14. Always use matching implements to cut down the diesel wastage. Implements should be maintained in good condition, as usage of worn out implements will waste fuel. 15. Always plough length wise and plan your field run to reduce fuel consumption. Adjust the wheel track to suit the implement and avoid overlap when working in the field. 16. When using a PTO driven equipment, operate the engine at the recommended speed to reduce fuel consumption.
