SAFETY STARTING

(1)Do not start the engine by shorting across starter terminals or bypassing the safety start switch.

(2)Do not alter or remove any part of machine safety system.

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

(4)Never start the engine while standing on ground. Start the engine only from operator'sseat.

00000Z00030

SAFETY WORKING

(1)Do not work on the machine while under the influence of alcohol, medication,or other substances or while fatigued.

(2)Wear close fitting clothingiand safety equipment appropriate to the job.

(3)Use tools appropriate to the work. Makeshift tools, parts, and procedures are not recommended.

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

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

(6)Do not touch the rotating or hot parts while the engine is running.

(7)Never remove the radiator cap while the engine is running, or immediately after stopping. Otherwise, hot water will spoutouLfrom 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.

(8)Escaping fluid (fuel or hydraulic oil) under pressure can penetrate the skini9ausing serious injury. Relieve pressure before disconnecting hydraulic or fuel lines. Tighten all connections •before applying pressure.

00000Z00040

AVOID FIRES

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

(2)To/avoid sparks from an accidental short circuit, always <disconnect the battery negative cable. first and connect it last.

(3)Battery gas can explode.Ke~p sparks and open flame away from the top of battery, especially when charging the. battery.

(4)Make sure that no fuel has been spilled on the engine.

VENTILATE WORK AREA

(1)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.

00000200060

PREVENT ACID BURNS

(1)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.

00000200070

DISPOSE OF FLUIDS PROPERLY

(1)Do not pour fluids into the ground, down a drain, or into a stream,pond, or lake. Observe relevant environmental protection regulations when disposing of oil, fuel, coolant, electrolyte and other harmful waste.

00000200080

PREPARE FOR EMERGENCIES

(1)Keep a first aid kit and fire extinguisher handy at all times.

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

[3] GENERAL PRECAUTIONS

			•	During disassembly, carefully arrange removed parts in a clean
				area to prevent confusion later. 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 tractor performance and to assure safety.
(A)		(B)	•	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

[4] 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 wlrmg 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 for a fee.

•Do not attempt to modify or remodel any electrical parts and wiring.

11790F00060

• When removing the battery cables, disconnect the negative cable first. When installing the battery cables, connect the positive cable first.

•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.

A 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.

Changing Engine Oil

A 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 line on the dipstick (2) .

•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-8.)

Replacing Engine Oil Filter Cartridge

A CAUTION

•Be sure to stop the engine before changing oil filter cartridge.

1.Remove the oil filter cartridge with the filter wrench.

2.Apply a slight coat of oil onto the cartridge gasket.

3.To install the new cartridge, screw it in by hand. Over tightening may cause deformation of rubber gasket.

4.After the new cartridge has been replaced, the engine oil normally decrease a little. Thus see that the engine oil does not leak through the seal and be sure to read the oil level on the dipstick. Then, replenish the engine oil up to the specified level.

•IMPORTANT

•To prevent serious damage to the engine, replacement element must be highly efficient. Use only a KUBOTA genuine filter or its equivalent.

A CAUTION

•Be sure to stop the engine checking and changing the transmission fluid.

1.Place an oil pan under the tractor.

2.Remove the drain plugs (1) at the bottom of the rear axle cases and oil tank.

3.Drain the transmission fluid.

4.After draining, screw in the three drain plugs.

5.Fill new oil from filling port after removing the filling plug (2) up to the upper notch on the dipstick.

6.After running the engine for a few minutes, stop it and check the oil level again, if low, add oil prescribed level.

•IMPORTANT

•Use only mUlti-grade transmission oil. Use of other oils may damage the transmission or hydraulic system.

Refer to "LUBRICANTS AND FLUID" (See page G-8).

•Never work the tractor immediately after changing the transmission oil. Keeping the engine at medium speed for a few minutes to prevents damage to the transmission.

•Do not mix different blands oil together.

1. Drain the transmission fluid.

2. Remove the oil filter cartridge by using a filter wrench. 3. Apply a slight coat of oil onto the cartridge gasket.
