SAFE OPERATION

-1SAFE OPERATION

Careful operation is your best insurance against an
accident.
Read and understand this Operator's Manual carefully
before operating the vehicle.
All operators, no matter how much experience they may
have, should read this and other related manuals before
operating the vehicle or any implement attached to it. It is
the owner's obligation to instruct all operators in safe
operation.

1. BEFORE OPERATING THE VEHICLE

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

2. Pay special attention to the Danger, Warning and
Caution labels on the vehicle.

3. Do not remove Roll-Over Protective Structures
(ROPS) for any application and fasten seat belts at all
times. This combination will reduce the risk of serious
injury or death, should the vehicle be upset.
If the ROPS is loosened or removed for any reason,
make sure that all parts are reinstalled correctly before
operating the vehicle.
Never modify or repair a ROPS because welding,
bending, drilling, grinding, or cutting may weaken the
structure.
A damaged ROPS structure must be replaced, not
repaired or revised.
If any structural member of the ROPS is damaged,
replace the entire structure at your local KUBOTA
Dealer.

5. Do not operate the vehicle 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 the
vehicle or any implement attached to it. Check for
overhead clearance which may interfere with the CAB
or ROPS. Do not allow any bystanders around or near
the vehicle during operation.

7. Never allow anyone without a valid driver's license to
operate this vehicle.

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

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

10.This vehicle is for off road use only.
KUBOTA does not recommend operating on public
roads.

11.In addition to the driver, only 1 passenger should ride
in the vehicle.
Minimum age for passenger is 5 years old.

12.Keep all shields in place and stay away from all
moving parts.

13.Check brakes, speed control pedal, 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.)

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

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

16.The maximum cargo capacity of this vehicle is 200kg.
Reduce cargo capacity to match operating conditions.
Do not carry anything which raises the center-of­gravity and sticks outside the cargo bed.

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

(1) ROPS
(2) Seat belt

4. Always use the seat belts. Check the seat belts
regularly and replace if frayed or damaged.

SAFE OPERATION-2

2. OPERATING THE VEHICLE

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.

5. The vehicle cannot turn with the differential locked and
attempting to do so could be dangerous.

6. Do not operate near ditches, holes, embankments, or
other ground surface features which may collapse
under the vehicle's weight. The risk of vehicle upset is
even higher when the ground is loose or wet.

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

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

9. Never try to get on or off a moving vehicle.

10.Do not stand between vehicle and trailer unless
parking brake is applied.

C Starting

1. Always sit in the operator's seat when starting engine
or operating levers or controls.

2. Before starting the engine, make sure that all levers
are in their neutral positions, that the parking brake is
engaged.

3. Do not start engine by shorting across starter
terminals or bypassing the safety start switch. The
vehicle may start in gear and move if normal starting
circuitry is bypassed.

4. Be sure that the operator (and passenger) seat belts
are fastened.

5. Do not operate or idle engine in a non-ventilated area.
Carbon monoxide gas is colorless, odorless, and
deadly.

C Operating

1. Do not wear headphones while operating.

2. Pull only from the trailer hitch (if equipped). Never hitch
to axle housing or any other point except trailer hitch;
such arrangements will increase the risk of serious
personal injury or death due to a vehicle upset.

C Safety for children

Tragedy can occur if the operator is not alert to the
presence of children. Children generally are attracted to
vehicles 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 vehicle down if children enter
the work area.

4. Never carry children in the cargo bed. There is no safe
place for them to ride. No person under the age of 5
may ride as a passenger in this vehicle. A passenger
under 5 years of age requires special restraints which
are not available with this vehicle.

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

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

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

8. Whenever possible, park your vehicle on a firm, flat
and level surface. If this is not possible, park it across
the slope. Set the parking brake(s), lower the
implements to the ground, remove the key from the
ignition and chock the wheels.

(1) Trailer hitch (if equipped)

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

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

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. Travel straight up or down hill.

2. Reduce load when operating on hilly or over rough
terrain.

3. Keep front wheels straight at crest of hill or going over
bumps.

4. Do not stop or start suddenly when going uphill or
downhill. Be especially cautious when changing
direction on slopes.

-3SAFE OPERATION

5. If vehicle stops or loses power going up a hill, lock
parking brake to hold vehicle on slope. Maintain
direction of travel and release brake slowly. Back
straight downhill while maintaining control. Do not turn
vehicle sideways. Vehicle is more stable in a straight
forward or rearward position.

6. When riding on soft terrain, turn front wheels slightly
uphill to keep vehicle on a straight line across the hill.

7. If the vehicle begins to tip, turn front wheels downhill to
gain control before proceeding.
(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 vehicle to
be upset backward. Always back out of these
situations. Extra caution is required with 4-wheel
drive mode because the increased traction can
give the operator false confidence in the vehicle'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) Special attention should be made to the weight

and location of implements and loads as such will
affect the stability of the vehicle.

C Operation in inclement conditions

1. Only operate during daylight or with good artificial
light.

2. Operate vehicle in an open, unobstructed area.

3. Use helmet and/or protective gear for certain
operating conditions.

4. Reduce speed according to trail, terrain and visibility
conditions.

5. Never drive exceeding the limit of visibility. Slow down
near crest of hill until getting a clear view of the other
side.

6. Stay alert for holes, rocks and other hidden hazards in
the terrain.

7. Never cross any body of water where depth may be
unknown to the operator (Deep water is considered
anything above the bottom edge of the axle cap).
Choose a course within the waterway where both
banks have a gradual incline. Cross at a point known
to be safe.

5. Do not apply the differential lock while traveling at high
speeds. The vehicle may run out of control.

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

C Other miscellaneous

1. Clean platform if dirty and remove any debris from
around foot controls.

2. Always keep both hands on the steering wheel.

3. Always keep arms and legs inside the operating
compartment.

4. Never operate the vehicle while standing.

5. Do not tow a cart with any riders on it.

6. Never attempt wheelies, jumps or other stunts.

3. HAULING LOADS IN THE CARGO BED

1. No riders in cargo bed or anywhere else.

2. Do not overload vehicle. Securely anchor all loads.

3. Be sure load is evenly distributed.

4. Reduce cargo capacity when operating on rough or
hilly terrain.

5. Balance loads evenly and secure them. Braking could
shift the load and affect vehicle stability.

6. Never operate vehicle with the cargo bed raised.

7. Operate cargo bed dump with vehicle stationary and
parking brake locked. Do not dump while moving.

8. Operate the cargo bed dump on level ground only.

9. Do not place hands or body under the cargo bed when
lowering bed.

4. PARKING THE VEHICLE

1. 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 vehicle 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 and always with attachment on the
ground.
Failure to comply with this warning may allow the
vehicle to move and could cause injury or death.

C Driving the vehicle at high speeds

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

2. Always slow the vehicle down before turning. Turning
at high speed may tip the vehicle over.

3. Turn the headlights on.

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

SAFE OPERATION-4

(1) Parking brake lever

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

5. TRANSPORTING

1. Disengage power to attachment(s) when transporting
or not in use.

2. Do not tow this vehicle. Use a suitable truck or trailer
when transporting on public roads.

3. Use extra care when loading or unloading the vehicle
into a trailer or truck.

6. SERVICING THE VEHICLE

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

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

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

3. 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.

4. Before "jump starting" a dead battery, read and follow
all of the instructions. (See "JUMP STARTING" in
"OPERATING THE ENGINE" section.)

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

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

7. 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 marks.

(1) Battery

9. 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 vehicle 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.)

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.

12.Securely support the vehicle when changing wheels.

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
the vehicle or any vehicle elements for servicing or
adjustment, securely support them with stands or
suitable blocking beforehand.

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.
"High pressure fluid - Injection into body" hazard
warning.

-5SAFE OPERATION

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.

(1) Cardboard
(2) Hydraulic line
(3) Magnifying glass

17.Waste products such as used oil, fuel, hydraulic fluid,
and batteries, can harm the environment, people, pets
and wildlife. Please dispose properly.
See your local Recycling Center or KUBOTA Dealer to
learn how to recycle or get rid of waste products.

OPERATING THE ENGINE12

BCold Weather Starting

When the ambient temperature is below 0 (32 ), the
engine is very cold. If the engine fails to start after 10
seconds, turn off the key for 30 seconds. Then repeat
steps 3 and 4. To protect the battery and the starter, make
sure that the starter is not continuously turned for more
than 10 seconds.

STOPPING THE ENGINE

1. After slowing the engine to idle, turn the key to "OFF".

2. Remove the key.

WARMING UP

To avoid personal injury:
A Be sure to set the parking brake during warm-

up.

A Be sure to set the range shift lever to the

"NEUTRAL" position.

For 5 minutes after engine start-up, allow the 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.

BWarm-Up Transmission Oil in the 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 Warm-up time requirement

Above 0 (32 ) Approx. 5 minutes

-10 to 0 (14 to 32 ) 5 to 10 minutes

-20 to -10 (-4 to 14 ) 10 to 15 minutes

Below -20 (-4 ) More than 15 minutes

A Do not operate the vehicle 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 vehicle battery is frozen, do not jump start

engine.

A Do not connect other end of negative jumper

cable to negative terminal of vehicle battery.

A The parts such as the muffler may be hot. Be

careful not to get burned in connecting jumper
cables.

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

1. Bring helper vehicle with a battery of the same voltage
as disabled vehicle within easy cable reach. "THE
VEHICLES MUST NOT TOUCH".

2. Engage the parking brake of both vehicles and put the
shift lever in neutral. Shut the engine 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 vehicle 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 vehicle.

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

11.Remove and discard the damp rags.

13OPERATING THE ENGINE

(1) Dead battery
(2) Lay a damp rag over the vent caps
(3) Jumper cables

starting" a low or dead battery.

14 OPERATING THE VEHICLE

OPERATING THE VEHICLE

OPERATING NEW VEHICLE

How a new vehicle is handled and maintained determines
the life of the vehicle.
A new vehicle 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 vehicle 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
vehicle is handled during the "breaking-in" period greatly
affects the life of your vehicle. Therefore, to obtain the
maximum performance and the longest life of the vehicle,
it is very important to properly break-in your vehicle. In
handling a new vehicle, the following precautions should
be observed.

BDo not Operate the Vehicle at Full Speed

for the First 50 Hours

A Do not start quickly nor apply the brakes suddenly.
A In winter, operate the vehicle 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 vehicle at fast speed. The above
precautions are not limited only to new vehicles, but to
all vehicles. But it should be especially observed in the
case of new vehicles.

STARTING

1. Fasten the seat belt.

BSeat Belt

To avoid personal injury:
A Seat belts reduce injury. Always wear your seat

belts. The lap-style seat belts may not provide
adequate protection for small children. Special
care is recommended when carrying a child
passenger.

To avoid personal injury:
A Always use the seat belts when operating and

riding in the vehicle.

Adjust the seat belts for proper fit and connect the buckle.
This seat belt is an auto-locking retractable type.

BChanging Lubricating Oil for New

Vehicles

The lubricating oil is especially important in the case of a
new vehicle. The various parts are not "broken-in" and are
not accustomed to each other. Small pieces of metal grit
may develop during the operation of the vehicle; 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.

to the "L" range to control the vehicle speed.

A If you shift gears while ascending or

descending a slope, be prepared to use the
brake to maintain control.

A Operate in reverse at slow speeds to maintain

control.

1. The range gear shift lever can only be shifted when
vehicle is completely stopped and the speed control
pedal is in the "NEUTRAL" position.

2. To avoid transmission and shift linkage damage,
completely stop the vehicle using the brake pedal
before shifting gears.

3. Select proper gear and engine speed depending on
the type of job.

DAILY CHECK

For your own safety and maximum service life of the
vehicle, make a thorough daily inspection before
operating the vehicle to start the engine.

To avoid personal injury:
A Be sure to check and service the vehicle on a

flat surface with the engine shut off and the
parking brake "ON".

BWalk Around Inspection

Look around and under the vehicle for such items as loose
bolts, trash build-up, oil or coolant leaks, broken or worn
parts.

BChecking Amount of Fuel and Refueling

To avoid personal injury:
A Handle fuel carefully. If the engine is running,

do not fill the fuel tank. If engine is hot, let
engine cool several minutes before adding fuel.
Do not smoke while filling the fuel tank or
servicing the fuel system. Fill fuel tank only to
bottom of filler neck. Do not fill completely full.
The empty space in the tank allows gasoline to
expand, when it heats up. Never remove the
fuel tank cap or add fuel when the fuel tank is
hot.

Check the fuel level. Take care that the fuel tank does not
become empty.

Fuel tank capacity 20 L (5.3 U.S.gals.)

A Do not mix oil with gasoline.

Use only unleaded gasoline with an octane rating index of
87 or higher may be used.

A Use fuel within approximately 30 days after purchase

to avoid deterioration in fuel quality, or add fuel
stabilizer to keep fuel fresh and stabilized.

A Fuel blend differs from season to season for the best

seasonal engine performance. To prevent engine
performance troubles such as vapor lock or hard
starting, use fuel within the season in which the fuel is
purchased.

A Infrequent use of the engine during a season can

make fuel stale in the fuel tank of the machine. Stale
fuel condition can cause engine performance troubles
by varnish and plugged carburetor components.

A Seal the fuel storage container tightly and store it out

of sunlight and heat to prevent fuel degradation.

A Condensation in the fuel tank may occur because of

various operating or environmental conditions. To
reduce condensation and avoid affecting machine
operation, fill the fuel tank at the end of daily operation
and store fuel in the plastic container.

A Use only an approved fuel container. Use only non-

metal, portable fuel containers approved by the
Underwriter's Laboratory (U.L.) or the American
Society for Testing & Materials (ASTM). If using a
funnel, make sure it is plastic and has no screen or
filter.

A Never remove the fuel tank cap or add fuel with the

engine running. Allow the engine to cool before
refueling.

A Never add fuel to or drain fuel from the machine

indoors. Move the machine outdoors and provide
adequate ventilation.

A Clean up spilled fuel immediately. If fuel is spilled on

clothing, change clothing immediately. If fuel is spilled
near machine, do not attempt to start the engine but
move the machine away from the area of spillage.
Avoid creating any source of ignition until fuel vapors
have dissipated.

A Never store the machine or fuel container where there

is an open flame, spark, or pilot light such as on a
water heater or other appliance.

A Prevent fire and explosion caused by static electric

discharge. Static electric discharge can ignite fuel
vapors in an ungrounded fuel container.

A Never fill containers inside a vehicle or on a truck or a

trailer bed with a plastic liner. Always place containers
on the ground away from your vehicle before fueling.

PERIODIC SERVICE42

A Remove fuel-powered equipment from the truck or the

trailer and refuel it on the ground. If this is not possible,
then refuel such equipment with a portable container,
rather than from a fuel dispenser nozzle.

A Keep the nozzle in contact with the rim of the fuel tank

or container opening at all times until the fueling is
complete. Do not use a nozzle lock-open device.

A Never overfill fuel tank. Replace the fuel tank cap and

tighten securely.

A Replace all fuel container caps securely after use.
A For gasoline engines, do not use gas with methanol.

Methanol is harmful to your health and to the
environment.

A Do not use stale fuel.
A Fill fuel tank at the end of daily operation to prevent

condensation in the fuel tank.

[Use of alcohol mixed gasoline (Gasohol)]

Use "gasohol" only when the ethanol additive is less than
10% of the fuel. The use of methanol additive is not
recommended. For the best results, use unleaded fuel
with a minimum of 87 octane.

BChecking Engine Oil Level

To avoid personal injury:
A Be sure to stop the engine before checking the

oil level.

1. Park the vehicle on a flat surface and raise the cargo
bed. Shut off the engine and remove the key.

2. Allow the engine to cool for 5 minutes or more.

3. To check the oil level, draw out the dipstick, wipe it
clean, replace it, and draw it out again. Check to see
that the oil level lies between the 2 notches.
If the level is too low, add new oil to the prescribed
level at the oil inlet.

45PERIODIC SERVICE

BChecking Brake Fluid Level

To avoid personal injury:
A Never operate the vehicle, if the brake fluid is

below the "MIN" mark.

A Use only KUBOTA DOT3 GENUINE BRAKE

FLUID from a sealed container. Using other
type of oil ruins synthetic resin or rubber
installed in brake system components, and
may cause brake failure.

A Avoid contamination of the brake fluid.

Thoroughly clean area around the filler cap
before removing. Do not open the brake fluid
reservoir cap unless absolutely necessary.

A Use extreme care when filling the reservoir. If

brake fluid is spilled on power steering hose,

BFlushing Cooling System and Changing

Coolant

To avoid personal injury:
A Do not remove the 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 and let cool down.

2. Remove the radiator maintenance cover.

3. To drain the coolant, open the radiator drain plug and
remove radiator cap. The radiator cap must be
removed to completely drain the coolant.

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

5. Fill with clean water and cooling system cleaner.

6. Follow directions of the cleaner instruction.

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

8. Fill with fresh water up to the "FULL" mark on the
recovery tank.

9. Start and operate the engine for few minutes.

10.Stop the engine and let cool.

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

Coolant capacity 1.8 L (1.9 U.S.qts.)

(1) Drain plug

(1) Radiator cap
(2) Recovery tank

A Do not start engine without coolant.
A Use clean, fresh water and anti-freeze to fill the

radiator and recovery tank.

A When the anti-freeze is mixed with water, the

antifreeze mixing ratio must be less than 50%.

A Securely tighten radiator cap. If the cap is loose or

improperly fitted, water may leak out and the engine
could overheat.

BAnti-Freeze

To avoid personal injury:
A When using antifreeze, put on some protection

such as rubber gloves. (Antifreeze contains
poison.)

A If should drink antifreeze, throw up at once and

take medical attention.

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.

(A) "FULL"
(B) "LOW"

67PERIODIC SERVICE

If it freezes, coolant can damage the cylinders and
radiator. If the ambient temperature falls below 0
(32 ) or before a long-term storage, let out cooling water
completely, or mix fresh water with long-life coolant and fill
the radiator and recovery tank with the mixture.

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
Put the LLC in cooling water in the percentage (%) for
a target temperature. 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.

A When the antifreeze is mixed with water, the

antifreeze mixing ratio must be less than 50%.

Vol %

Anti-freeze

Freezing Point Boiling Point*

A When the coolant level drops due to evaporation, add

water only to keep the antifreeze mixing ratio less than
50%. In case of leakage, add antifreeze and water in
the specified mixing ratio before filling into the radiator.

EVERY 1 YEAR

BChecking Radiator Hose and Clamp

Park the vehicle on a flat surface and raise the cargo bed.
Check to see if radiator hoses are properly fixed.

1. If hose clamps are loose or water leaks, tighten bands
securely.

2. Replace hoses and tighten hose clamps securely, if
radiator hoses are swollen, hardened or cracked.

Replace hoses and hose clamps if you checked and found
that hoses are swollen, hardened or cracked.

40 -24 -12 106 222

50 -37 -34 108 226

* At 1.013 x 10 Pa (760 mmHg) 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.

* 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 2000
hours or every 2 years whichever comes faster.
