Downloaded from www.Manualslib.com manuals search engine
HAND BRAKE before dismounting Leaving transmission in gear with engine
stopped will NOT prevent the tractor from moving Be sure everyone is clear of tractor and attached equipment before Starting engine
Never try to get on or off a moving tractor
When tractor is left unattended place In NUETRAL, Apply hand brake lower
implements to the ground stop the engine and remove the key
Use Caution on Hillsides
Always wear seat belt with ROPS in upper position Avoid holes ditches and obstructions which cause the tractor to tip especially on hillsides Avoid sharp uphill turns
Never drive near the edge of a gully or steep embankment-it might cave in
Driving forward out of a ditch or mired condition
or up a steep slope could cause tractor to tip over rearward Back out of these situations if possible
While mechanical front wheel drive greatly increases traction it DOES NOT increase stability of the tractor With mechanical front wheel drive engaged the tractor can climb steeper slopes but it does not become more stable When this option is used extra caution is needed on slopes Compared to a 2-wheeI drive a front Wheel drive tractor maintains traction on steeper slopes increasing the possibility of a tip over
Danger of overturn increases greatly with narrow tread setting at high speed
Hitch towed loads only to drawbar. When using a chain, take up the slack slowly
Protect Against Noise
Prolonged exposure to loud noise can cause impairment or loss of hearing
Wear a suitable hearing protective device such as earmuffs or earplugs to protect against objectionable or uncomfortable loud noises
Shift to Low Gear on Hills
Shift to a low gear before descending a
Downloaded from www.Manualslib.com manuals search engine
steep hill to improve your control of the tractor with little or no braking Use engine braking to reduce speed before applying tractor brakes Run-away tractors often tip over Never coast downhill
When driving on icy wet or graveled surfaces reduce speed and be sure tractor is properly ballasted to avoid skidding and loss of steering control For best control engage mechanical front wheel drive(if equipped) Additional ballast may be needed for transporting heavy hitch mounted implements When implement is raised drive slowly over rough ground regardless of how much ballast is used
Keep Riders Off Machine
Only allow the operator on the machine Keep riders off Riders on machine are subject to injury such as being struck by foreign objects and being thrown off of the machine Riders also obstruct the operator’s view resulting in the machine being operated in an unsafe manner
Freeing a Mired Machine
Attempting to free a mired machine can involve safety hazards such as the mired tractor tipping rearward the towing tractor overturning and the tow chain or tow bar (Actable is not recommended) failing and recoiling from its stretched condition
Back your tractor out if it gets mired down in mud Unhitch any towed implements Dig mud from behind the rear wheels Place boards behind the wheels to provide a solid base and try to back out slowly
If necessary dig mud from the front of all wheels and drive slowly ahead
If necessary to tow with another unit use a tow bar or a long chain(a cable is not recommended) Inspect the chain for flaws Make sure all parts of towing devices are of adequate size and strong enough to handle the load Always hitch to the drawbar of the towing unit Do not hitch to the front push bar attachment point Before
moving clear the area of people Apply power smoothly to take up the slack a sudden pull could snap any towing device causing it to whip or recoil dangerously
Avoid High-Pressure Fluids

Safety Precautions
General
■Your tractor was designed with safety very much in mind. However, there is no real substitute for caution and attention in preventing accidents. Once an accident has happened, it is too late to think about what you should have done.
■Read this manual carefully before attempting to start, operate, service, refuel or carry on other operating involving you tractor. A few minutes dedicated to reading will save time and trouble later.
■Remember that your tractor was designed and produced exclusively for agricultural use. If the owner of the tractor is to use it for any other purposes, he has to get the prior authorization from the Manufacturer in advance.
■Keep a first aid tool handy.
■Do not work with loose garments that could get caught in moving parts. Check that all rotating parts connected to the power take-off shaft are properly shielded.
■This tractor has to be operated by the people who were trained on the use and maintenance of it, and they also have to be duly authorized to operate it in advance.
■Do not attempt to increase the maximum engine rpm by altering the setting of the fuel injection system.
■Do not alter the pressure relief valve settings of the different hydraulic circuits hydraulic lift and remote control valves.
■Do not operate tractor if you feel unwell or physically unfit, in which case you should stop working.
■Always operate with the cab and rollover safety frame undamaged, complete of all components and correctly installed on the tractor; periodically check fastenings for tightness and frame and structures to make sure they are free from damages consequent on accidental impacts.
Starting the Tractor
■Prior to starting the engine, check that the parking brake is on and transmission and PTO are in neutral.
■Make sure all implements are fully lowered down to ground before starting the engine.
■Make sure, before starting the engine, that all guards, shields and protections are correctly installed on your tractor.
■Do not attempt to start or drive the tractor unless sitting in the operator’s seat.
■Always make sure, before starting the tractor in motion, that there are no people or obstacle within range.
■Do not run the engine inside closed premises without adequate ventilation, as exhaust fumes are harmful to health or may even become deadly.
Tractor Operation
■Select the track width setting best suitable to work, always keeping tractor stability in mind.
■Engage clutch gradually: abrupt engagements, particularly if pulling out of a rough area, a ditch or muddy grounds, or driving over a steep gradient, may cause dangerous tractor pitching.
15
Downloaded from www.Manualslib.com manuals search engine
Immediately disengage the clutch if front wheels tend to come off the ground.
■When coasting downhill, keep a transmission gear engaged. Never disengage the clutch and never drive your tractor in neutral.
■With tractor in motion, the operator should be correctly seated on driver’s seat.
■Do not get on or off a moving tractor.
■Always press the brake pedal gently.
■Do not corner at high speed.
■Always operate the tractor at a safe speed for the type of ground being worked. When operating on rough ground, use proper caution to assure tractor stability.
■When working on sloping grounds, as for example on hillsides, drive at moderate speed, slow down the tractor particularly when steering.
■Proceed with extreme caution when driving with wheels close to the edge of a ditch or bank.
■Never carry passengers.
■When driving on public roads, be sure to respect traffic rules and regulations.
■Do not override brake and clutch pedals.
■When driving on roads, latch the brake pedals together by using the latch plate. Braking with pedals unlatched may cause side skidding of the tractor. Moreover, avoid overworking the brakes.
Towing and Transport
■To assure tractor stability at work, correctly adjust the towing attachment depending on the towed trailer or drawn implement.
■For your personal safety, trailers should not be towed unless equipped with an independent braking system.
■Always use drawbar and towing equipment to pull heavy loads and avoid in any case hooking or connecting equipment to the 3-point hitch lower links or to the top link, because even in the last case pitching danger subsists.
■When towing, never negotiate bends with a locked differential because you might not be able to steer the tractor.
Using Agricultural Implements and Machinery
■Do not connect implements or machinery requiring a higher power rating than your tractor class.
■Never stand between tractor and implement to facilitate hitching while the tractor is being back up.
■Never actuate the power take-off shaft connected to an operating machine without making sure in advance that no one is within operating range of the same machine.
Stopping the Tractor
■Never leave implements in the raised position while the tractor is stationary, lower down the farm implements before shutting the engine off.
■Before leaving the tractor seat, be sure to move transmission control lever to neutral position, disengage the power take-off shaft, get the hand brake in working status by pulling its handle
and shut the engine off at last.
16
Downloaded from www.Manualslib.com manuals search engine
Besides, when leaving tractor unattended, always remove the key from the starter switch.
■When parking, look for level grounds if any, shift into a gear and lock the hand brake. On sloping grounds, besides locking the hand brake, shift into first forward gear if heading uphill or into first reverse gear if heading downhill. For more safety, also use the specific stopping wedge (available upon request). Be sure to do so if parking your tractor with a trailer.
Tractor Maintenance
■Allow engine to cool off sufficiently before removing the radiator cap. After the engine is shut down for some time, slowly turn the cap to release pressures before removing it completely.
■Disconnect the ground cable of storage battery before starting to work on any of the electrical system parts or component.
■Before disconnecting any hydraulic line or hose, make sure the system is pressure-free.
■Hydraulic oil escaping under pressure could cause serious personal injury. Consequently, when searching for or detecting oil leaks, make sure to use adequate safety protections such as shields, goggles and gloves.
■Prior to inspect, clean, adjust or carry on maintenance of the tractor or of any other mounted or connected implement, always make sure that engine is shut down, transmission is in neutral, brake are locked, power take-off is disengaged and all other moving parts are stationary.
■Do not operate on tyres unless suitable tools and the necessary experience are available. Any wrong tire installation may seriously involve your personal safety. If any doubt subsists, call on qualified persons.
■Do not fill up the fuel tank completely when expecting to work in full sunlight as the fuel might expand and escape. In such case, promptly wipe off any fuel stain.
■Tractor fuel may be dangerous. Never refuel while engine is running, or still hot, or near an open flame or when smoking.
