1

SAFE OPERATION

Careful operation is your best insurance against an accident.

Read and understand this manual carefully before operating the tractor.

All operators, no matter how much experience they may have, should read this and other related manuals before operating the tractor or any implement attached to it. It is the owner's obligation to instruct all operators in safe operation.

1. BEFORE OPERATING THE TRACTOR

1. Know your equipment and its limitations. Read this entire manual before attempting to start and operate the tractor.

2. Pay special attention to the danger, warning and caution labels on the tractor.

3. KUBOTA recommends the use of a CAB or Roll Over

Protective Structures (ROPS) and seat belt in almost all applications. This combination will reduce the risk of serious injury or death, should the tractor be upset.

If the CAB or ROPS is loosened or removed for any reason, make sure that all parts are reinstalled correctly before operating the tractor.

Never modify or repair a CAB or ROPS because welding, bending, drilling, grinding, or cutting may weaken the structure.

A damaged CAB or ROPS structure must be replaced, not repaired or revised. If any structural member of the

CAB or ROPS is damaged, replace the entire structure at your local KUBOTA Dealer.

5. Do not operate the tractor or any implement attached to it while under the influence of alcohol, medication, controlled substances or while fatigued.

6. Carefully check the vicinity before operating tractor or any implement attached to it. Check for overhead clearance which may interfere with a CAB or ROPS.

Do not allow any bystanders around or near tractor during operation.

7. Before allowing other people to use your tractor, explain how to operate and have them read this manual before operation.

8. Never wear loose, torn, or bulky clothing around tractor. It may catch on moving parts or controls, leading to the risk of an accident. Use additional safety items, e.g. hard hat, safety boots or shoes, eye and hearing protection, gloves, etc., as appropriate or required.

9. Do not allow passengers to ride on any part of the tractor at anytime. The operator must remain in the tractor seat during operation.

10. Check brakes, clutch, linkage pins and other mechanical parts for improper adjustment and wear.

Replace worn or damaged parts promptly. Check the tightness of all nuts and bolts regularly. (For further details, see "MAINTENANCE" section.)

11. Keep your tractor clean. Dirt, grease, and trash build up may contribute to fires and lead to personal injury.

12. Use only implements meeting the specifications listed under "IMPLEMENT LIMITATIONS" in this manual or implements approved by KUBOTA.

13. Use proper weights on the front or rear of the tractor to reduce the risk of upsets. When using the front loader, put an implement or ballast on the 3-point hitch to improve stability. Follow the safe operating procedures specified in the implement or attachment manual.

(1) Seat belt

4. Always use the seat belt if the tractor has a CAB or

ROPS. Do not use the seat belt if there is no CAB or

ROPS. Check the seat belt regularly and replace if frayed or damaged.

-

2 SAFE OPERATION

14. The narrower the tread, the greater the risk of a tractor upset. For maximum stability, adjust the wheels to the widest practical tread width for your application. (See

"TIRES, WHEELS AND BALLAST" section.)

5. Check before each use that operator presence controls are functioning correctly. Test safety systems.

(See "Checking Engine Start System" in "EVERY 50

HOURS" in "PERIODIC SERVICE" section.)

Do not operate unless they are functioning correctly.

C

Working

1. Pull only from the drawbar. Never hitch to axle housing or any other point except drawbar; such arrangements will increase the risk of serious personal injury or death due to a tractor upset.

(1) Rear wheels (A) Tread Width

15.Do not modify the tractor. Unauthorized modification may affect the function of the tractor, which may result in personal injury.

2. OPERATING THE TRACTOR

Operator safety is a priority. Safe operation, specifically with respect to overturning hazards, entails understanding the equipment and environmental conditions at the time of use. Some prohibited uses which can affect overturning hazards include traveling and turning with implements and loads carried too high etc. This manual sets forth some of the obvious risks, but the list is not, and cannot be, exhaustive. It is the operator's responsibility to be alert for any equipment or environmental condition that could compromise safe operation.

C

Starting

1. Always sit in the operator's seat when starting engine or operating levers or controls. Adjust seat per instructions in the operating the tractor section. Never start engine while standing on the ground.

2. Before starting the engine, make sure that all levers

(including auxiliary control levers) are in their neutral positions, that the parking brake is engaged, and that both the clutch and the Power Take-Off (PTO) are disengaged or "OFF".

Fasten the seat belt if the tractor has a CAB, a fixed

ROPS or a foldable ROPS in the upright and locked position.

3. Do not start engine by shorting across starter terminals or bypassing the safety start switch.

Machine may start in gear and move if normal starting circuitry is bypassed.

4. Do not operate or idle engine in a non-ventilated area.

Carbon monoxide gas is colorless, odorless, and deadly.

(1) Drawbar

2. Keep all shields and guards in place. Replace any that are missing or damaged.

3. Avoid sudden starts. To avoid upsets, slow down when turning, on uneven ground, and before stopping.

4. The tractor cannot turn with the rear wheel or 4-wheel differential locked and attempting to do so could be dangerous.

5. Do not operate near ditches, holes, embankments, or other ground surface features which may collapse under the tractor's weight. The risk of tractor upset is even higher when the ground is loose or wet. Tall grass can hide obstacles, walk the area first to be sure.

6. Watch where you are going at all times. Watch for and avoid obstacles. Be alert at row ends, near trees, and other obstructions.

7. When working in groups, always let the others know what you are going to do before you do it.

8. Never try to get on or off a moving tractor.

9. Do not stand between tractor and implement or trailed vehicle unless parking brake is applied.

C

Safety for children

Tragedy can occur if the operator is not alert to the presence of children. Children generally are attracted to machines and the work they do.

1. Never assume that children will remain where you last saw them.

2. Keep children out of the work area and under the watchful eye of another responsible adult.

3. Be alert and shut your machine down if children enter the work area.

SAFE OPERATION

-

3

4. Never carry children on your machine. There is no safe place for them to ride. They may fall off and be run over or interfere with your control of the machine.

5. Never allow children to operate the machine even under adult supervision.

6. Never allow children to play on the machine or on the implement.

7. Use extra caution when backing up. Look behind and down to make sure area is clear before moving.

8. When parking your machine if at all possible park on a firm, flat and level surface; if not, park across a slope.

Set the parking brake(s), lower the implements to the ground, remove the key from the ignition and lock the cab door (if equipped) and chock the wheels.

C

Operating on slopes

Slopes are a major factor related to loss-of-control and tipover accidents, which can result in severe injury or death.

All slopes require extra caution.

1. To avoid upsets, always back up steep slopes. If you cannot back up the slope or if you feel uneasy on it, do not operate on it. Stay off slopes too steep for safe operation.

2. Driving forward out of a ditch, mired condition or up a steep slope increases the risk of a tractor to be upset backward. Always back out of these situations. Extra caution is required with 4-wheel drive models because their increased traction can give the operator false confidence in the tractor's ability to climb slopes.

3. Keep all movement on slopes slow and gradual. Do not make sudden changes in speed, direction or apply brake and make sudden motions of the steering wheel.

4. Avoid disengaging the clutch or changing gears speed when climbing or going down a slope. If on a slope disengaging the clutch or changing gears to neutral could cause loss of control.

5. Special attention should be made to the weight and location of implements and loads as such will affect the stability of the tractor.

6. To improve stability on slope, set widest wheel tread as shown in "TIRES, WHEELS AND BALLAST" section.

Follow recommendations for proper ballasting.

C

Driving the tractor on the road

1. Lock the 2 brake pedals together to help assure straight-line stops. Uneven braking at road speeds could cause the tractor to tip over.

(1) Brake Pedal (LH)

(2) Brake Pedal (RH)

(3) Brake Pedal Lock

(A) Whenever travelling on the road

2. Check the front wheel engagement. The braking characteristics are different between 2 and 4-wheel drive. Be aware of the difference and use carefully.

3. Always slow the tractor down before turning. Turning at high speed may tip the tractor over.

4. Make sure that the Slow Moving Vehicle (SMV) sign is clean and visible. Use hazard lights and turn signals as required.

(1) SMV emblem

(2) Bracket

5. Observe all local traffic and safety regulations.

6. Turn the headlights on. Dim them when meeting another vehicle.

7. Drive at speeds that allow you to maintain control at all times.

8. Do not apply the differential lock while traveling at road speeds. The tractor may run out of control.

9. Avoid sudden motions of the steering wheel as they can lead to a dangerous loss of stability. The risk is especially great when the tractor is traveling at road speeds.

-

4 SAFE OPERATION

10.Keep the ROPS in the "UP" position and wear the seat belt when driving the tractor on the road.

Otherwise, you will not be protected in the event of a tractor roll-over.

11.Do not operate an implement while the tractor is on the road. Lock the 3-point hitch in the raised position.

12.Do not ride or stand on the step during operation.

Riding or standing there could result in being crushed under the rear tire due to slippage or the step fracturing or displacing due to unintended loading.

(1) Step

13.When towing other equipment, use a safety chain and place an SMV emblem on it as well.

3. PARKING THE TRACTOR

1. Disengage the PTO, lower all implements to the ground, place all control levers in their neutral positions, set the parking brake, stop the engine, and remove the key.

2. Make sure that the tractor has come to a complete stop before dismounting.

3. Avoid parking on steep slopes, if at all possible park on a firm and level surface; if not, park across a slope with chock the wheels.

Failure to comply with this warning may allow the tractor to move and could cause injury or death.

4. OPERATING THE PTO

1. Wait until all moving components have completely stopped before getting off the tractor, connecting, disconnecting, adjusting, cleaning, or servicing any

PTO driven equipment.

2. Keep the PTO shaft cover in place at all times.

Replace the PTO shaft cap when the shaft is not in use.

(1) Safety chain

(1) PTO Shaft cover

(2) PTO Shaft cap

(A) "NORMAL POSITION"

(B) "RAISED POSITION"

3. Before installing or using PTO driven equipment, read the manufacturer's manual and review the safety labels attached to the equipment.

To prevent PTO driven equipment from improper or unsafe use, select the lower speed (540rpm) unless the higher one is specifically recommended as safe by the equipment manufacture.

4. When operating stationary PTO driven equipment, always apply the tractor parking brake and place chocks behind and in front of the rear wheels. Stay clear of all rotating parts. Never step over rotating parts.

5. USING 3-POINT HITCH

1. Use the 3-point hitch only with equipment designed for

3-point hitch usage.

2. When using a 3-point hitch mounted implement, be sure to install the proper counterbalance weight on the front of the tractor.

3. When transporting on the road, set the implement lowering speed knob in the "LOCK" position to hold the implement in the raised position.

SAFE OPERATION

-

7. Disconnect the battery's ground cable before working on or near electric components.

8. To avoid the possibility of battery explosion, do not use or charge the refillable type battery if the fluid level is below the LOWER ( lower limit level ) mark. Check the fluid level regularly and add distilled water as required so that the fluid level is between the UPPER and

LOWER levels.

9. To avoid sparks from an accidental short circuit, always disconnect the battery's ground cable (-) first and reconnect it last.

(1) 3-point hitch lowering speed knob (A) "FAST"

(B) "SLOW"

(C) "LOCK"

(1) Battery

10. Do not attempt to mount a tire on a rim. This should be done by a qualified person with the proper equipment.

11. Always maintain the correct tire pressure. Do not inflate tires above the recommended pressure shown in the operator's manual.

6. SERVICING THE TRACTOR

Before servicing the tractor, park it on a firm, flat and level surface, set the parking brake, lower all implements to the ground, place the gear shift lever in neutral, stop the engine and remove the key.

1. Allow the tractor time to cool off before working on or near the engine, muffler, radiator, etc.

2. 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. If the tractor has a coolant recovery tank, add coolant or water to the tank, not the radiator. (See "Checking Coolant Level" in

"DAILY CHECK" in "PERIODIC SERVICE" section.)

3. Always stop the engine before refueling. Avoid spills and overfilling.

4. Do not smoke when working around battery or when refueling. Keep all sparks and flames away from battery and fuel tank. The battery presents an explosive hazard, because it gives off hydrogen and oxygen especially when recharging.

5. Before "jump starting" a dead battery, read and follow all of the instructions. (See "JUMP STARTING" in

"OPERATING THE ENGINE" section.)

6. Keep first aid kit and fire extinguisher handy at all times.

12. Securely support the tractor when either changing wheels or adjusting the wheel tread width.

13. Make sure that wheel bolts have been tightened to the specified torque.

14. Do not work under any hydraulically supported devices. They can settle, suddenly leak down, or be accidentally lowered. If it is necessary to work under tractor or any machine elements for servicing or adjustment, securely support them with stands or suitable blocking beforehand.

6 SAFE OPERATION

15.Escaping hydraulic fluid under pressure has sufficient force to penetrate skin, causing serious personal injury. Before disconnecting hydraulic lines, be sure to release all residual pressure. Before applying pressure to the hydraulic system, make sure that all connections are tight and that all lines, pipes, and hoses are free of damage.

16.Fluid escaping from pinholes may be invisible. Do not use hands to search for suspected leaks; use a piece of cardboard or wood. Use of safety goggles or other eye protection is also highly recommended. If injured by escaping fluid, see a medical doctor at once. This fluid will produce gangrene or severe allergic reaction.

OPERATING THE ENGINE 11

OPERATING THE ENGINE

To avoid personal injury:

A

Read "Safe Operation" in the front of this manual.

A

Read the danger, warning and caution labels located on the tractor.

A

To avoid the danger of exhaust fume poisoning, do not operate the engine in a closed building without proper ventilation.

A

Never start engine while standing on ground.

Start engine only from operator's seat.

A

Make it a rule to set all shift levers to the

"NEUTRAL" positions and to place PTO lever in

"OFF" position before starting the engine.

A

Do not use starting fluid or ether.

A To protect the battery and the starter, make sure that the starter is not continuously turned for more than 10 seconds.

STARTING THE ENGINE

1. Make sure the parking brake is set.

A Daily checks with the Easy Checker(TM) only, are not sufficient. Never fail to conduct daily checks carefully by referring to Daily Check.

(See "DAILY CHECK" in "PERIODIC SERVICE" section.)

7. Fully depress the clutch pedal.

COLD WEATHER STARTING

If the ambient temperature is below 0 (32 ) and the engine is very cold, follow the procedure below after taking the step 1 through 5 in the previous pages.

8. Turn the key to "START" position and release when the engine starts.

A

Because of the safety devices, the engine will not start except when the PTO clutch control lever is placed in the "OFF" position and shuttle shift lever is placed in the "NEUTRAL" position.

9. Check to see that all the lamps on the

Easy Checker(TM) are "OFF"

.

If a lamp is still on, immediately stop the engine and determine the cause.

10. Release the clutch pedal.

6. Turn the key to "ON" position and hold it until the heater indicator turns off.

Heater indicator comes on when the key is turned to "ON" position and engine coolant temperature is below 0

(32 ), and goes off automatically when preheat is completed.

Turn the key to the "START" position and the engine should start.

(If the engine fails to start after 10 seconds, turn off the key for 30 seconds. Then repeat steps 6 through 8. To protect the battery and the starter, make sure that the starter is not continuously turned for more than 10 seconds.)

B

Block Heater (if equipped)

A block heater is available as an option from your dealer.

It will assist you in starting your tractor when the ambient temperature is below -20 (-4 ).

OPERATING THE ENGINE 15

STOPPING THE ENGINE

1. After slowing the engine to idle, wait 3 to

5 minutes for turbo to slow down and then turn the key to "OFF".

2. Remove the key.

A If key does not stop the engine, consult your local

KUBOTA Dealer.

WARMING UP

To avoid personal injury:

A

Be sure to set the parking brake during warmup.

A

Be sure to set all shift levers to the "NEUTRAL" positions and to place PTO lever in "OFF" position during warm-up.

For 5 minutes after engine start-up, allow engine to warm up without applying any load, this is to allow oil to reach every engine part. If load should be applied to the engine without this warm-up period, trouble such as seizure, breakage or premature wear may develop.

B

Warm-up and Transmission Oil at Low

Temperature Range

Hydraulic oil serves as transmission fluid. In cold weather, the oil may be cold with increased viscosity. This can cause delayed oil circulation or abnormally low hydraulic pressure for some time after engine start-up. This in turn can result in trouble in the hydraulic system.

To prevent the above, observe the following instructions:

Warm up the engine at about 50 % of rated rpm according to the table below:

Ambient temperature

Higher than -10 (14 )

-15 to -10 (5 to 14 )

-20 to -15 (-4 to 5 )

Below -20 (-4 )

Warm-up time requirement

Approx. 10 minutes

10 to 20 minutes

20 to 30 minutes

More than 30 minutes

A

Do not operate the tractor under full load condition until it is sufficiently warmed up.

JUMP STARTING

To avoid personal injury:

A

Battery gases can explode. Keep cigarettes, sparks, and flames away from battery.

A

If tractor battery is frozen, do not jump start engine.

A

Do not connect other end of negative (-) jumper cable to negative (-) terminal of tractor battery.

When jump starting engine, follow the instructions below to safely start the engine.

1. Bring helper vehicle with a battery of the same voltage as disabled tractor within easy cable reach. "THE

VEHICLES MUST NOT TOUCH".

2. Engage the parking brakes of both vehicles and put the shift levers in neutral. Shut both engines off.

3. Put on safety goggles and rubber gloves.

4. Ensure the vent caps are securely in place. (if equipped)

5. Cover vent holes with damp rags. Do not allow the rag to touch the battery terminals.

6. Attach the red clamp to the positive (red, (+) or pos.) terminal of the dead battery and clamp the other end of the same cable to the positive (red, (+) or pos.) terminal of the helper battery.

7. Clamp the other cable to the negative (black, (-) or neg.) terminal of the helper battery.

8. Clamp the other end to the engine block or frame of the disabled tractor as far from the dead battery as possible.

9. Start the helper vehicle and let its engine run for a few moments. Start the disabled tractor.

10. Disconnect the jumper cables in the exact reverse order of attachment. (Steps 8, 7 and 6).

11. Remove and discard the damp rags.

OPERATING THE TRACTOR

OPERATING FOLDABLE ROPS OPERATING NEW TRACTOR

How a new tractor is handled and maintained determines the life of the tractor.

A new tractor just off the factory production line has been, of course, tested, but the various parts are not accustomed to each other, so care should be taken to operate the tractor for the first 50 hours at a slower speed and avoid excessive work or operation until the various parts become "broken-in". The manner in which the tractor is handled during the "breaking-in" period greatly affects the life of your tractor.

Therefore, to obtain the maximum performance and the longest life of the tractor, it is very important to properly break-in your tractor. In handling a new tractor, the following precautions should be observed.

B

Do not Operate the Tractor at Full Speed for the First 50 Hours.

A

Do not start quickly nor apply the brakes suddenly.

A

In winter, operate the tractor after fully warming up the engine.

A

Do not run the engine at speeds faster than necessary.

A On rough roads, slow down to suitable speeds. Do not operate the tractor at fast speed.

The above precautions are not limited only to new tractors, but to all tractors. But it should be especially observed in the case of new tractors.

B

Changing Lubricating Oil for New Tractors

The lubricating oil is especially important in the case of a new tractor. The various parts are not "broken-in" and are not accustomed to each other; small metal grit may develop during the operation of the tractor; and this may wear out or damage the parts. Therefore, care should be taken to change the lubricating oil a little earlier than would ordinarily be required.

For further details of change interval hours.

(See "MAINTENANCE" section.)

3-POINT HITCH CONTROL SYSTEM

B

Position Control

This will control the working depth of 3-point hitch mounted implement regardless of the amount of pull required.

B

Draft Control

This will control the pull of the 3-point implement. As the load on the 3-point hitch changes due to various soil conditions, the draft control system automatically responds to these changes by either raising or lowering the implement slightly to maintain a constant pull.

Place the position control lever in the lowest position and set the implement pull with the draft control lever.

(1) Draft control lever

(2) Position control lever

(A) "UP"

(B) "SENSITIVE"

(C) "INSENSITIVE"

B

Mixed Control

In draft control, when draft decreases, the implement automatically lowers to increase draft. However, the implement sometimes lowers too much. To limit the degree, the implement can be lowered, set the position control lever at the lowest working depth desired for the implement. Lower the draft control lever to the point where the implement is at the desired depth.

This stops the implement from going too deep and causing loss of traction and ground speed.

It is not possible to use triple segments with flow control valve.

B

Remote Control Valve

There are two types of remote valves available for these models.

A

Double acting valve with detents and self cancelling:

This valve may be placed in the detent mode. The lever will stay in this position until the pressure reaches a predetermined level or a cylinder reaches the end of its stroke. Then it will automatically return to neutral

A Double acting valve with float position:

This valve may be placed in the float mode with the control lever all the way forward. The cylinder is free to extend or retract, letting an implement such as a loader bucket follow the ground.

To avoid personal injury:

A

Fast lowering speed may cause damage or injury. Lowering speed of implement should be adjusted to 2 or more seconds.

Flow Control Valve (option)

The optional flow control valve may be added for the following purposes.

1. To operate within limits, the remote control valve (2) above the flow control valve (3) and the 3-point hitch at the same time without one affecting the other.

2. To operate within limits, the remote control valve (2) above the flow control valve (3) and the other remote control valve (1) at the same time without one affecting the other. Activating the remote control valve (1) will interrupt the operation of the 3-point hitch.

3. To maintain within limits, the constant speed of an attachment (hydraulic motor RPM, for example) when connected to the remote control valve (2) above the flow control valve (3).

A At slower engine speeds the total hydraulic flow rate may be inadequate for simultaneous operation of the remote control valve (2) and the 3-point hitch or the remote control valve (1), or operation of an attachment connected to the remote control valves (1)(2). Under these conditions, the engine speed must be increased to provide additional hydraulic flow.

B

Adjusting the flow rate

HYDRAULIC UNIT 49

Refer to the illustration below.

1. The flow rate for the remote control valve (2), located on above the flow control valve (3), can be adjusted.

2. Turn the flow control knob (4) counterclockwise (A), and the flow rate for the remote control valve (2) increases. A clockwise turn (B) of the knob causes the flow to decrease. If the knob is turned all the way (C), there will be no flow.

3. To adjust the flow rate, set the engine speed to the operating RPM, turn the flow control knob once all the way clockwise (C), and then turn it gradually counterclockwise until a required flow rate is reached.

A Full adjustment of the valve will occur in approximately

1 1/2 revolutions of the flow control knob. Turning the flow control knob beyond this point will have no affect on the flow rate.

A

When there is no need to adjust the flow rate, turn the flow control knob all the way counterclockwise and keep it in this position.

To avoid the possibility of personal injury be aware of the following when making adjustments:

A

The 3-point hitch operation is influenced by the combination of the adjustment of the flow control valve and the engine speed.

A

The 3-point hitch may raise slowly or not at all at low engine RPM.

A Engine Oil:

A Oil used in the engine should have an American Petroleum Institute (API) service classification and Proper SAE

Engine Oil according to the ambient temperatures as shown above.

A

With the emission control now in effect, the CF-4 and CG-4 lubricating oils have been developed for use of a lowsulfur fuel on on-road vehicle engines. When an off-road vehicle engine runs on a high-sulfur fuel, it is advisable to employ the CF, CD or CE lubricating oil with a high total base number.

If the CF-4 or CG-4 lubricating oil is used with a high-sulfur fuel, change the lubricating oil at shorter intervals.

To avoid personal injury:

A

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

A

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.

A

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

A

Do not mix different types of Antifreeze.

The mixture can produce chemical reaction causing harmful substances.

A

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

A

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

A

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

A

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.

Consult your local KUBOTA Dealer concerning coolant for extreme conditions.

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.

Vol %

Freezing Point Boiling Point*

50 -37 -34 108 226

D

At 1.013 x 10 Pa (760mmHg) pressure (atmospheric).

A higher boiling point is obtained by using a radiator pressure cap which permits the development of pressure within the cooling system.

5. Adding the LLC

(1) Add only water if the mixture reduces in amount by evaporation.

(2) If there is a mixture leak, add the LLC of the same manufacturer and type in the same mixture percentage.

D

Never add any long-life coolant of different manufacturer. (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.
