[10] CHECK POINTS OF EVERY 2 YEARS

Flushing Cooling System and Changing Coolant

Warning

To avoid personal injury or death:

•Do not remove radiator cap while coolant is hot. When cool, slowly rotate cap to the first stop and allow sufficient time for excess pressure to escape before removing the cap completely.

1.Stop the engine, remove the key and let it cool down.

2.To drain the coolant, disconnect the radiator hose (engine side) and remove the radiator cap. The radiator cap must be removed to completely drain the coolant.

3.After all coolant is drained, close the drain plug.

4.Fill with clean water and cooling system cleaner.

5.Follow directions of the cleaner instruction.

6.After flushing, fill with clean water and anti-freeze until the coolant level is just below the radiator cap. Install the radiator cap securely.

7.Fill with coolant up to the "FULL" mark on the recovery tank.

8.Start and operate the engine for few minutes.

9.Stop the engine, remove the key and let cool.

10.Check coolant level of recovery tank and add coolant if necessary.

11.Properly dispose of used coolant.

IMPORTANT

•Do not start engine without coolant.

•Use clean, fresh water and anti-freeze to fill the radiator and recovery tank.

•When the anti-freeze is mixed with water, the anti-freeze mixing ratio must be less than 50 %.

•Securely tighten radiator cap. If the cap is loose or improperly fitted, water may leak out and the engine could overheat.

Warning

To avoid personal injury or death:

•When using antifreeze, put on some protection such as rubber gloves (Antifreeze contains poison.).

•If it is swallowed, seek immediate medical help. Do NOT make a person throw up unless told to do so by poison control or a health care professional. Use standard first aid and CPR for signs of shock or cardiac arrest. Call your local Poison Control Center or your local emergency number for further assistance.

•When antifreeze comes in contact with the skin or clothing, wash it off immediately.

•Do not mix different types of Antifreeze. The mixture can produce chemical reaction causing harmful substances.

•Antifreeze is extremely flammable and explosive under certain conditions. Keep fire and children away from antifreeze.

•When draining fluids from the engine, place some container underneath the engine body.

•Do not pour waste onto the grounds, down a drain, or into any water source.

•Also, observe the relevant environmental protection regulations when disposing of antifreeze. Always use a 50/50 mix of long-life coolant and clean soft water in KUBOTA engines.

1.Long-life coolant (hereafter LLC) comes in several types. Use ethylene glycol (EG) type for this engine.

2.Before employing LLC-mixed cooling water, fill the radiator with fresh water and empty it again. Repeat this procedure 2 or 3 times to clean up the inside.

3.Mixing the LLC

Premix 50 % LLC with 50 % clean soft water. When mixing, stir it up well, and then fill into the radiator.

4.The procedure for the mixing of water and antifreeze differs according to the make of the antifreeze and the ambient temperature. Refer to SAE J1034 standard, more specifically also to SAE J814c.

*At 1.013 × 105 Pa (760 mmHg) pressure (atmospheric). A higher boiling points is obtained by using a radiator pressure cap which permits the development of pressure within the cooling system.

[11] OTHERS

5.Adding the LLC a)Add only water if the mixture reduces in amount by evaporation. b)If there is a mixture leak, add the LLC of the same manufacture and type in the same mixture percentage. *Never add any long-life coolant of different manufacture. (Different brands may have different additive components, and the engine may fail to perform as specified.)

6.When the LLC is mixed, do not employ any radiator cleaning agent. The LLC contains anticorrosive agent. If mixed with the cleaning agent, sludge may build up, adversely affecting the engine parts.

7.Kubota's genuine long-life coolant has a service life of 2 years. Be sure to change the coolant every 2 years.

NOTE

•The above data represent industry standards that necessitate a minimum glycol content in the concentrated anti-freeze.

Bleeding Fuel System

Air must be removed:

1.When the fuel filter or lines are removed.

2.When the tank is completely empty.

3.After the tractor has not been used for a long period of time. Bleeding procedure is as follows.

1.Fill the fuel tank with fuel.

2.Start the engine and run for about 30 seconds, and then stop the engine.

Draining Clutch Housing Water

NOTE

•The tractor is equipped with a water drain plug (1) under the clutch housing.

•After operating in rain, snow or tractor has been washed, water may get into the clutch housing.

1.Remove the drain plug and drain the water, then install the plug again.

Replacing Fuse

1.The tractor electrical system is protected from potential damage by fuses.

A blown fuse indicates that there is an overload or short somewhere in the electrical system.

2.If any of the fuses should blow, replace with a new one of the same capacity.

IMPORTANT

•Before replacing a blown fuse, determine why the fuse blew and make any necessary repairs. Failure to follow this procedure may result in serious damage to the tractor electrical system.
