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.

3. HANDLING PRECAUTIONS FOR ELECTRICAL PARTS
AND WIRING
To ensure safety and prevent damage to the machine and
surrounding equipment, heed the following precautions in handling
electrical parts and wiring.
IMPORTANT
■
• Check electrical wiring for damage and loosened
connection every year. To this end, educate the customer to
do his or her own check and at the same time recommend
the dealer to perform periodic check while carrying out
routine servicing.
• Do not attempt to modify or remodel any electrical parts and
wiring.
• When removing the battery cables, disconnect the negative
cable first. When installing the battery cables, connect the
positive cable first.
W10111140
[1] WIRING
• Securely tighten wiring terminals.
W10112160
• Do not let wiring contact dangerous part.
W10113130
• Securely insert grommet.

• Securely clamp, being careful not to damage wiring.
W10114580
• Clamp wiring so that there is no twist, unnecessary sag, or
excessive tension, except for movable part, where sag be
required.
W10115870
• In installing a part, take care not to get wiring caught by it.
W10116700
• After installing wiring, check protection of terminals and clamped
condition of wiring, only connect battery.

[2] BATTERY
• Take care not to confuse positive and negative terminal posts.
• When removing battery cables, disconnect negative cable first.
When installing battery cables, check for polarity and connect
positive cable first.
• Do not install any battery with capacity other than is specified
(Ah).
• After connecting cables to battery terminal posts, apply high
temperature grease to them and securely install terminal covers
on them.
• Do not allow dirt and dust to collect on battery.
CAUTION
• Take care not to let battery liquid spill on your skin and
clothes. If contaminated, wash it off with water immediately.
• Before recharging the battery, remove it from the machine.
• Before recharging, remove cell caps.
• Do recharging in a well-ventilated place where there is no
open flame nearby, as hydrogen gas and oxygen are formed.
W10118160
[3] FUSE
• Use fuses with specified capacity.
Neither too large or small capacity fuse is acceptable.
• Never use steel or copper wire in place of fuse.
• Do not install working light, radio set, etc. on machine which is not
provided with reserve power supply.
• Do not install accessories if fuse capacity of reserve power
supply is exceeded.
W10120920
[4] CONNECTOR
• For connector with lock, push lock to separate.

4. LUBRICANTS, FUEL AND COOLANT
* KUBOTA original transmission hydraulic fluid.
NOTE
■
• 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.
• 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 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.
• Lubricating oil recommended when a low-sulfur or high-sulfur fuel is employed.

7. CHECK AND MAINTENANCE
CAUTION
• Be sure to check and service the tractor on a flat place with engine shut off, the parking brake on and chock
the wheels.
[1] DAILY CHECK
To prevent trouble from occurring, it is important to know the condition of the tractor. Check the following items
before starting.
Checking
• Check areas where previous trouble was experienced.
• Walk around the tractor.
1. Check the tire pressure, and check for wear and damage.
2. Check for oil and water leak.
3. Check the engine oil level.
4. Check the transmission fluid level.
5. Check the coolant level.
6. Check the condition of seat belt and ROPS attaching hardware.
7. Check and clean the radiator screen and grill.
8. Check the nuts of tires are tight.
9. Care of danger, warning and caution labels.
10.Clean around the exhaust manifold and the muffler of the engine.
• While sitting in the operator’s seat.
1. Check the brake pedals and clutch pedal.
2. Check the parking brake.
3. Check the steering wheel.
• Turning the key switch.
1. Check the performance of the easy checker lights.
2. Check the lights, turn signal lights, hazard lights and other light equipment. Clean if necessary.
3. Check the performance of the meters and gauges.
• Starting the engine.
1. Check to see that the lights on the easy checker go off.
2. Check the color of the exhaust gas.
3. Check the brakes for proper operation.

G-11
[2] CHECK POINTS OF INITIAL 50 HOURS
Changing Engine Oil
CAUTION
• Before changing oil, be sure to stop the engine.
1. Start and warm up the engine for approx. 5 minutes.
2. Place an oil pan underneath the engine.
3. To drain the used oil, remove the drain plug (1) at the bottom of
the engine and drain the oil completely.
4. Screw in the drain plug (1).
5. Fill new oil up to upper hole on the dipstick (3).
IMPORTANT
■
• When using an oil of different manufacture or viscosity from
the previous one, remove all of the old oil.
• Never mix two different types of oil.
• Use the proper SAE Engine Oil according to ambient
temperatures.
• Refer to “LUBRICANTS, FUEL AND COOLANT”. (See page
G-7).
W1014533
Replacing Engine Oil Filter Cartridge
CAUTION
• Be sure to stop the engine before changing oil filter
cartridge (1).
• Allow engine to cool down sufficiently, oil can be hot and
can burn.
1. Remove the engine oil filter cartridge (1).
2. Put a film of clean engine oil on rubber seal of new filter.
3. Tighten the filter quickly until it contacts the mounting surface.
Tighten filter by hand an additional 1/2 turn only.
4. After the new filter has been replaced, the engine oil normally
decreases a little. Make sure that the engine oil does not leak
through the seal and be sure to check the oil level on the dipstick.
Then, replenish the engine oil up to the prescribed level.
IMPORTANT
■
• To prevent serious damage to the engine, replacement
element must be highly efficient. Use only a KUBOTA
genuine filter.

Changing Transmission Fluid
CAUTION
• Be sure to stop the engine before checking and changing
the transmission fluid.
1. Place and oil pan underneath the transmission case.
2. Remove the drain plugs (1) at the bottom of the transmission
case.
3. Drain the transmission fluid.
4. After draining, screw in the drain plugs (1).
5. Fill with the new KUBOTA SUPPER UDT fluid up to the upper
line of the gauge (2).
6. After running the engine for a few minutes, stop it and check the
fluid level again, if low, add fluid prescribed level (A).
IMPORTANT
■
• Use only multi-grade transmission fluid. Use of other fluids
may damage the transmission or hydraulic system.
• Refer to “LUBRICANTS, FUEL AND COOLANT”. (See page
G-7.)
• Never work the tractor immediately after changing the
transmission fluid. Keeping the engine at medium speed for
a few minutes to prevent damage to the transmission.
• Do not mix different brands oil together.
