Emergency Procedures
1. In case of a brake failure, hold the steering wheel firmly, wait until the tractor has come to a complete stop
and then shut down the engine.
2. If the steering malfunctions, brake immediately and shut down the engine.
3. If fire should occur, immediately shut down the engine. If a fire extinguisher is available, put out the
flames at the source of the flame; if a fire extinguisher is not available, use sand or other non-flammable
substance to fight the fire.
4. After any safety incident, immediately dial any necessary emergency services (hospital, fire department)
according to the situation and administer first-aid as necessary.
Warning:
1. Always operate the tractor in a safe and responsible manner to avoid injury and possible death.
2. Pay special attention to any obstacles that may impede progress or cause an accident before
starting the tractor. Also check for obstacles and impediments that may be covered by the
tractor, an implements or a trailer.
3. Never leave the driver’s seat to start and operate the tractor. Prior to the startup, make sure that
various shift levers are in the neutral position, the throttle lever and the front drive control handle
are disengaged and the lifter operating handle is in neutral to prevent the sudden start up of
accessories.
4. Do not start the engine by bridging-over the solenoid. If you do this, the tractor could lose
control and cause a dangerous situation, which could lead to injury or death.
5. Make sure that the pedals are free from obstacles and able to move unhindered to their home
position. Never keep anything on the floor or around the pedals that could hinder treadle travel. An
extra foot blanket or non-standard floor mats should not be used as they can hinder pedal
movement and cause serious injury or damage.
6. Never get on or off the tractor while it is in motion.
7. Never climb under the tractor while the engine is running.
8. Always remove the keys, set all shift levels to neutral and lock the auxiliary brake handle
before exiting the cab to avoid accidental start up and to keep the tractor from moving
unattended.
9. Keep your speed under control at all times. Brake prior to turning in order to maintain your load
and avoid tipping.
10. When crossing a bridge or going through a tunnel, pay full attention to the load height.
11. Use the lowest gear with the clutch enabled on a down slope. Never put the tractor in neutral and
coast downhill as this can cause instability. Never change gears on a down slope as this can cause
instability and a possible rollover.
12. Avoid sudden turns at high speed or using unilateral braking to turn as this can result in
instability.
13. When driving on roads, obey all local traffic indicators and laws.
14. Keep a safe distance between the tractor and any other vehicles that may be on the road.
15. Roadbeds along the ditch line tend to be more fragile. Pay specific attention to the weight of

Caution:
your vehicle when riding on the road shoulder.
16. Never overload the tractor. Running the tractor over the specified limits can cause damage to
the tractor and can result in injury.
17. When driving at night, make sure that you have proper lighting to avoid any collisions.
18. When working in tall grass or hay, a spark-extinguishing device must be affixed to the exhaust pipe to
avoid accidental fires.
19. Always slow down when working in wet or rainy conditions to avoid slippage and instability.
20. Always operate the tractor at a safe speed.
21. When attaching implements, make sure all 3-Point hitch pins are securely fastened. When
disconnecting implements assure all 3-Point hitch pins are disconnected.
22. When lifting, reduce engine speed to avoid damage to tractor and personal injury.
23. Upon charging the battery, insure proper ventilation.
24. Beware of overhead high voltage transmission line!
1. Check nuts, bolts, nuts and other loose components regularly and tighten as required. This could
prevent a potentially dangerous situation.
2. When the tractor runs by power take-off (PTO), make sure that there is a safety shield installed.
Never approach the PTO shaft when it is running. Never take sudden turns when the PTO shaft is
under load, as this can damage the universal joint or the PTO shaft. When the PTO shaft is not in
use, the lever should be returned to the neutral position.
3. After parking and before shutting down the tractor, the driver should remove the key from the
ignition, set all gearshift levers to the neutral position, and lock the brake handle. This will
prevent the tractor from accidental startup and unattended movement.
4. When parking the tractor on an incline, the hand braking should be engaged and the engine shut
down. Put the tractor in gear, apply the auxiliary brake and use the triangle chocks to block the rear
wheels.
5. Tire installation and adjustment should be done by trained personnel only, using special tools.
Faulty installation may cause a serious accident or damage.
6. When cleaning the radiator, shut down the tractor and allow the tank to cool for.
7. Pay attention to all safety precautions when replacing or installing new parts on your tractor.

Safety Precautions

Important:
1. Always operate the tractor according to the specified running-in requirements. This will prolong
the life of your tractor.
2. Prior to starting the tractor, the oil system, cooling system and electric circuits must be examined.
After startup, strict attention should be paid to the various instruments.
3. Before activating the PTO shaft, make sure that the equipment is properly inspected. When using
PTO implements, the angle between the PTO shaft and the universal joint drive shaft should be
no more than a 15° angle; the hydraulic operating control should be neutral, and after the farm
tool has been lifted, the included angle between the power take-off shaft and the universal joint
drive shaft should be at no more than 20° angle. Never use the implement without checking for a
proper connection with the power take-off. This can cause damage to the implement and severe
damage to the tractor clutch and power train. To increase work efficiency, the power supply
should never be shut off at the curve and the lifting height must be maintain at 200mm above the
ground.
4. Hanging farm implements can shift tractor weight and should be low to the ground before
exiting the tractor.
5. Antifreeze should always be used in the cooling system.
6. The front driving axle of tractor should only be engaged in agricultural instances and when roads
are muddy. Overuse of the front drive axle may result in premature wear of the tires and
transmission problems.
7. Only use parts recommended by the manufacturer to replace worn or broken components.
8. Never rest your foot on the brake or clutch pedal when the tractor is in motion as this can cause
premature wear of the brakes and clutch system.

Safety Precautions

9. When detaching the tractor from any implements, the upper lever of the suspension unit should
be adjusted to the shortest travel and the limit lever adjusted to prevent the implements from
swinging out of control. The locking nuts on the upper and limit levers must be tighten in order
to guarantee travel safety and to avoid damage to the tractor and the machinery.
1.2 Safety Warning Symbols
Caution:
1. All safety identifiers should be visible and easy to read. When dirty, wash with soapy water and clean them
with a soft rag.
2. When the safety identifiers are lost or damaged, contact the sales department or the manufacturer for
replacement stickers.
3. When replacing parts with attached Safety warning symbols, the safety identifiers that correspond to that
specific part need to be updated as well.
4. To prevent injury, accidents and damage, always comply with safety warning identifiers.
During machine operation, keep a safe distance from the hot surface of the

Preventing Farm Machine Hazards
The following article describes important general safety precautions for machinery such as the NT-204C/NT-254 tractor.
It is reprinted here with permission from Professor Thomas L. Bean, Safety Leader and Professor, Department of Food,
Agricultural, and Biological Engineering, The Ohio State University Extension, The Ohio State University.
AEX-593-91
Thomas L. Bean
Each year, 2,600 farm residents are killed and 230,000 disabled in farm-related injuries, many due to farm machinery.
Farm machinery uses mechanical power to do work. This creates a number of possible hazards for both operators
and bystanders. Even though manufacturers take many steps to make machinery safe, all hazards cannot be removed.
Some machine parts cannot be completely shielded and still do their job. For instance, a totally enclosed cutting
blade could not cut.
Many machinery-related accidents result from human error. The operator either forgot something, took a shortcut or
a risk, ignored a warning, wasn’t paying close attention, or failed to follow safety rules. In addition, guards removed
for maintenance often aren’t replaced.
There are many different kinds of farm machinery: mowers, tractors, shredders, harvesters, grinders, blowers, augers,
balers, etc. They all have similar characteristics and hazards. You can be cut, crushed, pulled in or struck by an
object thrown by these machines. They have cutting edges, gears, chains, revolving shafts, rotating blades, pinch
points and other hazards. You can also be injured if you fall while working on or near any of these machines.
Accidents with farm machinery are often serious, even fatal. It is important to recognize and be alert for machine
hazards and to take precautions to avoid injury.
Shear and Cutting Points
Shear points (Fig. 1 below) are created when the edges of two objects are moved together closely enough to cut a soft
material, as with a pair of shears or an auger. Cutting points are created when a single object moves forcefully or
rapidly enough to cut, as with a rotary mower blade.
Figure 1

Safety Precautions
11
Both shear and cutting points are created on machinery designed to cut, such as harvesters, and on those that are not
designed to cut, such as augers. They are hazardous because of their cutting force and they often move so rapidly
that they may not be visible, so it is easy to forget they are operating or to underestimate the hazard.
Because some shear and cutting points cannot be guarded, it is important to be aware of their hazard and stay alert
when they are operating. It is also important to warn others and to look out for their safety. This is especially true
if there is a danger of thrown objects while using cutting-type equipment.
Pinch Points
Pinch points are another hazard of farm machinery (Fig. 2 below). Pinch points (which should be more
appropriately named mangled or maimed points) are formed when two rotating objects move together and at least one
of them moves in a circle. For example, the point at which a belt runs into a pulley is a pinch point. Belt drives,
chain drives, and gear drives are other sources of pinch points in power transmission devices. Feed rolls, gathering
chains and similar equipment designed to draw crops into the machine also create pinch points.
Fingers, hands and feet can be caught directly in pinch points, or they may be drawn into the pinch points by the
inertia of the moving part or loose clothing that becomes entangled. Contact may be made by falling or brushing
against unshielded parts. You can become entangled in pinch points if you take chances and reach or work near
rotating parts. Machines move too fast to get out of a pinch point once you become caught.
To avoid injury from pinch points, be aware where pinch points occur and avoid them. Wear clothing that fits well
and is not loose or floppy. Never reach over or work near rotating parts. Turn off machinery to work on it.
Always replace shields removed for maintenance.
Wrap Points
Rotating shafts are the most common source of wrap-point accidents, although any exposed machine part that rotates
can be a wrap point. A cuff, sleeve, pant leg, long hair or just a thread can catch a rotating part and result in serious
injury. Entanglement with a wrap point can pull you into the machine, or clothing may become so tightly wrapped
that you are crushed or suffocated. In other cases, you could be thrown off balance and fall into other machinery
parts.
Even a perfectly round shaft can be hazardous if there is enough pressure to hold clothing against the shaft. Hazards
Figure 2

Safety Precautions
12
increase with shafts that are not round. Clothing is more likely to catch if there is dried mud or manure on the shaft,
or if the shaft is nicked. Ends of shafts that protrude beyond bearings are also dangerous. Universal joints, keys
and fastening devices can also snag clothing.
Check all equipment for potential wrap points and, if possible, shield those that can be shielded. Replace any
damaged manufacturer-installed warning labels and place warnings on equipment parts not previously labeled. In
addition, consider painting them a bright color, perhaps with wide stripes. Be aware of wrap points and be alert to
their danger.
Crush Points
Crush points are created when two objects move toward each other or one object moves toward a stationary object.
For example, hitching tractors to implements (Fig. 3 below) creates a potential crush point.
Hitch accidents most commonly occur to fingers placed at the hitching point. Wait until the tractor has stopped
before stepping into the hitching position. If possible, arrange the hitch point so that the tractor can be backed into
position without anyone between. Always know what the other person is doing.
Failure to safely block up equipment can result in a fatal crushing injury. A jack may slip, a hose or overhead
support may break, or the equipment may roll. Take extra precautions when working with machinery that is raised
for any reason. The operator’s head or chest can be crushed between the equipment and a low beam or other part of
a farm building. These accidents usually occur when the machine is being operated in reverse. Tree limbs are also
potential hazards when working with tractors and other machinery.
To prevent being crushed or pinned, recognize and avoid potentially dangerous situations. Block all machinery
securely if you must work under it. If an implement can roll freely, block its wheels so it cannot roll.
Free-Wheeling Parts
Many machine parts continue to spin after the power is shut off, including cutter heads of forage harvesters, hammer
mills of feed grinders, rotary mower blades, fans and flywheels. Never touch these parts until they have stopped
moving. This could take 2 to 21/2 minutes.
Figure 3

Safety Precautions
13
Springs
Compressed springs (Fig. 4 below) will expand with great force when released, and springs that are stretched will
contract rapidly when released. Know what direction a spring will move and how it might affect another machine
part when released, and stay out of its path.
Burn Points
Be aware of burn points: mufflers, manifolds and even gear cases under adverse climatic conditions. They may not
be severe enough to seriously maim, but they can startle the operator enough to cause him or her to “jump” into more
deadly danger.
Hydraulic Systems
Hydraulic systems contain fluid under extreme pressure. Before loosening, tightening, removing or otherwise
working with any fittings or parts, relieve this pressure. Jet streams from even pinhole leaks can penetrate flesh. In
addition, the liquid is often hot.
Before attempting any service on hydraulic systems, shut off the engine that powers the hydraulic pump. Lower the
implement to the ground and relieve the pressure. Follow instructions in the operator’s manual because the specific
procedures for servicing the systems are very important to your safety.
