SAFETY INSTRUCTIONS

SAFETY STARTING

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

• Do not alter or remove any part of machine safety
system.

• Before starting the engine, make sure that all shift
levers are in neutral positions or in disengaged
positions.

• Never start the engine while standing on ground.
Start the engine only from operator’s seat.

SAFETY WORKING

• Do not work on the machine while under the influe nce
of alcohol, medication, or other substances or while
fatigued.

• Wear close fitting clothing and safety equipment
appropriate to the job.

• Use tools appropriate to the work. Makeshift tools,
parts, and procedures are not recommended.

• When servicing is performed together by two or more
persons, take care to perform all work safely.

• Do not work under the machine that is supported
solely by a jack. Always support the machine by
safety stands.

• Do not touch the rotating or hot parts while the engine
is running.

• Never remove the radiator cap while the engine is
running, or immediately after stopping. Otherwise, hot
water will spout out from radiator. Only remove
radiator cap when cool enough to touch with bare
hands. Slowly loosen the cap to first stop to relieve
pressure before removing completely.

• Escaping fluid (fuel or hydraulic oil) under pressure
can penetrate the skin causing serious injury. Relieve
pressure before disconnecting hydraulic or fuel lines.
Tighten all connections before applying pressure.

AVOID FIRES

• Fuel is extremely flammable and explosive under
certain conditions. Do not smoke or allow flames or
sparks in your working area.

• To avoid sparks from an accidental short circuit,
always disconnect the battery negative cable first and
connect it last.

• Battery gas can explode. Keep sparks and open
flame away from the top of battery, especially when
charging the battery.

• Make sure that no fuel has been spilled on the engine.

SAFETY INSTRUCTIONS

VENTILATE WORK AREA

• If the engine must be running to do some work, make
sure the area is well ventilated. Never run the engine
in a closed area. The exhaust gas contains poisonous
carbon monoxide.

PREVENT ACID BURNS

• Sulfuric acid in battery electrolyte is poisonous. It is
strong enough to burn skin, clothing and cause
blindness if splashed into eyes. Keep electrolyte
away from eyes, hands and clothing. If you spill
electrolyte on yourself, flush with water, and get
medical attention immediately.

DISPOSE OF FLUIDS PROPERLY

• Do not pour fluids into the ground, down a drain, or
into a stream, pond, or lake. Observe relevant
environmental protection regula tions when disp osing
of oil, fuel, coolant, electrolyte and other harmful
waste.

PREPARE FOR EMERGENCIES

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

• Keep emergency numbers for doctors, ambulance
service, hospital and fire department near your
telephone.

2. GENERAL PRECAUTIONS

• During disassembly, carefully arrange removed parts in a clean
area to prevent confusion later. Screws, bolts and nuts should be
installed in their original position to prevent reassembly errors.

• When special tools are required, use KUBOTA genuine special
tools. Special tools which are not frequently used should be
made according to the drawings provided.

• Before disassembling or servicing electrical wires, always
disconnect the ground cable from the battery first.

• Remove oil and dirt from parts before measuring.

• Use only KUBOTA genuine parts for parts replacement to
maintain machine performance and to assure safety.

• Gaskets and O-rings must be replaced during reassembly.
Apply grease to new O-rings or oil seals before assembling.
See the figure left side.

• When reassembling external snap rings or internal snap rings,
they must be positioned so that sharp edge faces against the
direction from which a force is applied. See the figure left side.

• When inserting spring pins, their splits must face the direction
from which a force is applied. See the figure left side.

• To prevent damage to the hydraulic system, use only specified
fluid or equivalent.

• Engine Oil : Oil used in the engine should have an Ame rican Petroleum Institute (API) service classification
and Proper SAE Engine Oil according to the ambient temperature as shown above.
Do not mix different brands together.

• With the emission control now in effect, the CF-4 and CG-4 lubricating oils have been developed for use
of a low-sulfur fuel 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 o il with a high total base number. If the CF-4 or CG­4 lubricating oil is used with a high-sulfur fuel, change the lubricating oil at shorter intervals.

• Lubricating oil recommended when a low-sulfur or high-sulfur fuel is employed.

• Transmission Oil : The oil used to lubricate the transmission is also used as hydraulic fluid. To insure
proper operation of the hydraulic system and complete lubrication of the transmission, it is important that
a multi-grade transmission fluid be used in t his syste m. We rec ommend t he use of KUBOTA SUPER UDT
fluid for optimum protection and performance.
Do not mix different brands together.

• Indicated capacity of water and oil are manufacture’s estimate.

Q Anti-Freeze

CAUTION

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

• If should drink antifreeze, throw up at once and take medical
attention.

• 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 caus ing 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 conta iner
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.

If it freezes, coolant can damage the cylinders and radiator. If the

ambient temperature falls below 0 °C or befor e a long- term storage ,
let out coolant completely, or mix fresh water with long-life coolant
and fill the radiator and reserve 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 coolant, 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 coolant 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.

IMPORTANTQ

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

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
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.

NOTEQ

• The above data represents industry standards that
necessitate a minimum glycol co ntent in the concentrated
anti-freeze.

• 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 in to the radiator.

Q Bleeding procedure is as follows:

1. Fill the fuel tank with fuel, and open the fuel cock (1).

2. Pump the fuel pump knob (2) located on the top of the fuel filter.
The fuel pump knob will pump easily at first and with added
resistance as air is purged from the system. To make sure air is
completely purged, pinch the fuel overflow hose (3) with fingers,
if a pulsation is felt when the knob is pumped, then, no air
remains.

3. Set the hand throttle lever at the maximum speed position, turn
the key switch to start the engine, and then reset the throttle lever
at the mid speed (around 1500 min
