Safety Precautions

1. Safety Precautions

1.1 Safety Rules and Notices of Use

Reading Prior to Use

1 The instructions for use, maintenance, and the safety warning

identifiers should be fully read and understood.

2. The correct usage and operating method should be observed.

3. Local traffic rules and safety regulations must be observed at all times.

Fig. 1-1 Reading prior to use

AQualified Operator

1. When operating the machine, the driver must use sound judgment.

2. Never operate the tractor if you have been drinking or are tired.

3. The driver should read and understand this operator’s manual.

4. Drive slowly at first in order to test your skill level.

Clothing

During the operation, the driver should avoid loose fitting clothing.

Baggy and bulky clothes are not recommended.

Fig.1-3 Driver’s clothes

Fuel Usage

1. Diesel fuel is a combustible substance. Keep all fuel away

from open flames.

2. The engine should be shut down prior to refueling.

3. Smoking is strictly prohibited when the fuel system is

being refueled and overhauled.

4. Use a clean rag to wipe off any fuel or machine oil overflow.

5. The requirements set out in the “Appendix” must be strictly

complied with for fuel and lubricating oil quality assurance.

Fig.1-4 Use of fuel

Fig.1-2 A qualified operator

Safety Precautions

Waste Oil Disposal

1．Used machine oil is a hazardous waste. Dispose of it properly.

2．The used acid from the battery is also a hazardous waste. Dispose of it properly.

Fig.1-5 Waste oil disposal

Hydraulic Line Leaks

Do not use your hand to check for leaks in the high-pressure hydraulic oil lines.

You may use a piece of cardboard or a wooden board to test for possible leaks.

Fig. 1-6 Hydraulic line leaks

Removing the Radiator Cap

Never remove the radiator cap when the engine is hot. Turn the engine off

and wait until the engine has cooled, then turn the cap to the first position.

Once pressure has been reduced, you can then remove the cap.

Fig. 1-7 Removing the radiator cap

Electric Parts Maintenance

1. Remove the ignition switch key.

2. Never service any of the tractor’s electrical components without

first removing the ground wire from the battery.

Fig. 1-8 Electric parts maintenance

In Case of Defects orAbnormal Operation

1. The tractor should not be operated “in spite of defects.” In case of a

lack of oil pressure, excessively low oil pressure, an overly high water

temperature or unusual sounds and smells, stop the tractor and

troubleshoot the problem.

2. During lubrication maintenance and for any on-field adjustment,

the engine should be shut down.

Fig. 1-9 In case of defects or abnormal operation

Safety Precautions

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 and get off the tractor. 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 implement 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 starter 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 pedal 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

Safety Precautions

Caution:

avoid tipping.

10. When crossing or going under 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 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 lines!

1. Check nuts, bolts and other loose components regularly and tighten as required. This could prevent a

potentially dangerous situation.

2. When the tractor runs the power take-off (PTO), make sure that there is a safety shield installed.
