Before handling diesel fuel, refer to the chapter 5-1-(3), 5-1-(5) in this manual.

Before handling Bio-diesel, refer to the chapter 5-1-(4) in this manual.

Fire hazard!

When handling diesel fuel, observe the following precautions:

1. Do not smoke. Keep any type of flame away.

2. Never fill the tank when the engine is running.

3. Wipe up spilled fuel immediately. Always tighten the fuel tank cap securely.

Failure to comply could result in death or serious injury.

Pull the throttle lever to the low idle position.

Start the engine after operating the cold start aid indicator sufficiently.

If the engine runs rough, push the throttle pedal down 2-3 times for a while. (Mechanical type)

If the engine runs smoothly, carry out warm-up for 5-10 minutes at low idle position.

Use the engine oil for winter in cold weather. Refer to the chapter 5-3, “Lubricants and Capacity” or the last page in this manual.

Use the diesel for winter when it is very cold weather. It is much easier to start the engine.

When storing the tractor in cold weather, the battery must be removed and stored in a cool and dry place that is not frozen away from children.

Allowing engine to idle for a long time will waste fuel and cause a build up of carbon.

Breathing diesel engine exhaust exposes you to chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.

Always start and operate the engine in a well-ventilated area.

If in an enclosed area, vent the exhaust to the outside.

Do not modify or tamper with the exhaust system.

Do not idle the engine except as necessary.

Battery post, terminals and related accessories contain lead and lead compounds.

When handling engine oil, diesel fuel, anti-freeze solution and other chemical substances, wear protective clothes, mask and gloves.

WASH YOUR HANDS AFTER HANDLING.

Wash your tractor cleanly and follow the procedure as below.

Apply grease or lubricant oil or spray paint to the non-painted metal to avoid corrosion. Keep the tractor in a covered, dry and well-ventilated place. Temperature: 10℃ ~ 35℃ (50℉ ~ 95℉), Humidity: 45% ~ 70%.

Place all controls, including electrical switches, in neutral position and apply the wheel chocks to the tires and disengage the parking brake.

Check the lubricant level of each parts and if the engine oil has exceeded 100 hours of work, change the oil and run the engine for 5 minutes at idle rpm.

Drain engine coolant completely. If the engine coolant is anti-freeze solution, it is not necessary to drain but check its density.

Fill the fuel tank full with fuel.

Loosen all drive belts and clean the air cleaner.

Loosen the rubber plug (if fitted) under the clutch chamber to drain water.

Remove the battery, clean the cover and smear the terminals with grease. Place the battery in a ventilated place not less than 10°C (50°F) and away from direct sunlight.

Remove the lift-rod and place the lift-arm to the highest position to lubricate the lift cylinder.

If possible, fit stands or other suitable supports under the axles to raise the wheel off the ground. And let the air out of the tires. If not, check the tire pressure from time to time.

Remove the ignition key.

Cover the tractor with a non-water-proof cover.

If the implements are attached, lower the implements on a support off the ground.

Apply grease or lubricant oil regularly to the non-painted parts.

Check the leakage of fuel, oil and coolant. If necessary, repair the damaged part.

Check if the tire air pressure is normal.

Start engine periodically, at least every 6 month for circulation and lubrication in fuel system.

The battery should be charged about once a month not to be discharged entirely.

As the electrolyte of battery is sulfuric acid, it is emits the explosive and poisonous gas. It is strong enough to burn skin, clothing and can cause blindness if splashed into eyes. Keep the sparks and flames and cigarettes away from the battery. When handling the battery, wear safety glasses to protect the eyes. If the electrolyte contacts the eyes and skin, wash with water immediately and go to see a doctor.

When removing and storing battery, select dry and cool place out of reach of children.

When using first after long-term storage, check each part as below.

Inflate the tires to the recommended pressures and remove the blocking.

Check the damaged part or loosen part.

Check the leakage of fuel, coolant, engine oil, transmission and front axle oil.

Check the level and density of the engine coolant.

Check the level of engine, transmission, rear and front axle oil, and fuel. (For further information, refer to the chapter 5, “Lubrication and Maintenance” in this manual.)

Check all drive belts carefully, paying particular attention to the point where the straight run of the belt starts to bend around the pulley. Check the vee groove in the pulley for corrosion.

Electric system check

• Is there any open circuit or any other problem in the wiring?
• Is there any problem of the instruments?
• Is the charging state of the battery sufficient?

• when working with tiller on hard ground.
• When crossing a ridge

When driving on public roads, disengage the 4WD. If not, it may cause damage of the transmission drive line and a serious accident. After working, before coming out from the field, select the 2WD.

When driving the tractor at high speed while the 4WD is engaged, sharp steering may cause an accident.

If the tractor cannot go forward as one side rear wheel is slipping, stop the tractor and press down the differential lock pedal.

The differential lock is effective for working on a slippery ground.

If the differential lock is engaged, both rear wheels will rotate at equal speed. So, It can disturb the steering operation and you cannot turn smoothly.

Take your foot off the pedal to release the differential lock. If the differential traction force is reduced to some extend, the differential lock is released automatically.

If the differential lock does not disengaged automatically, i.e., the turning radius is larger than normal condition and the turning is not smooth, turn the steering wheel left and right after stopping the tractor.

Do not turn the tractor while the differential lock is engaged.

Do not use this differential lock while driving on public roads.

Stop or drive slow the tractor before engaging the differential lock.

Hydraulic oil leaking under pressure can penetrate skin and cause infection or other injury. To prevent personal injury, comply with the instructions as below.

• Relieve all pressure before disconnecting hydraulic lines.
• Before applying pressure, make sure all connections are tight and components are in good condition.
• Never use your hand to check for suspected leaks under pressure.
• If injured by leaking fluid, get medical attention immediately.

The hydraulic hoses and fittings on your tractor meet engineering specifications for the particular function. When replacing damaged parts, use only manufacture authorized service parts.

Care in hydraulic hose installation is a must:

• Make sure pressure is relieved before starting installation procedure.
• DO NOT kink or twist a hose, failure may occur. Properly route the hose.
• Have a certified hydraulic technician install the hose.
• Remove air from the hydraulic system after installing any hydraulic component.

Periodically check hydraulic system for leaks or damaged parts – kinked, crushed, flattened, hard blistered, heat cracked, charred, twisted, soft or loose covered hoses and fittings.

DO NOT pull or apply external forces to the hose. The hose may fail and cause injury.

Keep all persons away from the working area. If a hose fails, mechanisms controlled by fluid power can become hazardous. Lifted mechanisms can fall to the ground, steering system may fail, etc.

Stay clear of a pressurized hose assembly that has blown apart. Hose fittings can be thrown off at high speed and a loose hose can whip around with great force.

Hydraulic oil can reach high temperatures. Wait for all components to cool before you perform any maintenance or adjustment operation. Do not handle any service fluid (engine coolant, engine oil, hydraulic oil, etc.) at temperatures that exceed 50 °C (122 °F). Allow fluids to cool.

Vibration can reduce hose service life. Make sure all retaining clamps and/or devices are secured.

Environmental conditions can cause hose and fittings to deteriorate. You must periodically inspect the hydraulic hoses. The hoses do not require any operator-performed maintenance. Always see your authorized local dealer for hydraulic hose repair or replacement. Replace worn or damaged hoses and fittings.

Before checking or repairing the hydraulic system, make sure the engine is stopped, and all the transmission gears are in neutral, and lower the implements to the ground.

Before removing hydraulic pipes or hoses and other parts, make sure to check that hydraulic pressure is relieved completely. The leaks of pressurized oil can cause a fatal physical injury.

Use proper protection equipment, before servicing the hydraulic system.

Before connecting or disconnecting the hydraulic quick coupler, lower the implements to the ground, and check if the hydraulic pressure is relieved.

The hydraulic steering system controlled by fluid power provides you more convenience to operate the steering wheel.

Notices when using the steering system:

1. If there is too much of a load in front-end loader bucket, it could be difficult to operate the steering wheel. In this case, it is necessary to reduce the size of the load.

2. Do not operate the tractor unnecessarily in a state of fully steered front wheels for a long time. As unnecessary hydraulic force is applied to the steering linkage, it may cause damage to the steering system and excessive increase of the hydraulic oil temperature which may cause reduction of the product life or a failure of the hydraulic and steering system. Especially, DO NOT operate the steering wheel excessively when a front wheel is mired in a ditch. The rim and disk of the wheel could be damaged or deformed.

3. If an abnormal noise sounds off when operating the steering wheel, this may mean that there is some air in the steering components or lines. In this case, turn the steering wheel to the left and right direction fully about 2-3 times. It will exhaust the air and the abnormal noise shall disappear. If it’s not cleared, contact your authorized local dealer for check.

4. When starting engine in cold weather, an abnormal noise may occur. In this case, warm up the tractor before using it in order to reduce the oil viscosity.

When the engine is stopped, the steering wheel becomes hard to turn. But this does not mean a failure. It can be only used in an emergency state.

When releasing the steering wheel after steering operation while driving, the steering wheel does not return to neutral position automatically.

The 3-point linkage can be lifted/lowered by using the position control lever as below.

1. Push the position control lever forward, the 3-point linkage goes down.

2. Pull the position control lever backward, the 3-point linkage goes up. The raising speed is depend on the engine speed. If it does not raised at the low rpm, increase the engine speed.

3. If releasing the position control lever, the lever goes to neutral automatically and the 3-point linkage shall be stopped.

It is use to adjust the down speed of the 3-point linkage. Turn the knob to the right direction in order to lower the implement slower, and to the left direction for faster down speed.

If turning the knob right direction fully, the implement shall be fixed and even if lowering down the position control lever, the implement does not let down.

• Tiller : Slow in down speed
• Plough : Fast in down speed

When working in hard ground, slow down the down speed to avoid the bounding of the implement.

When driving on the road, replacing tiller blades or removing grass around the tiller blades, turn the down-speed control knob clockwise slightly to lock.

The knob rotates about two revolutions. Do not over-tighten the knob. It may cause damage to the control valve and connection parts.

This is used to operate the hydraulic cylinder and/or motor of the implement attached to the tractor by the hydraulic oil pressure.

If you push the remote control lever forward, the hydraulic pressure works to the upper coupler, and the lower coupler is connected to the drain.

After connecting and preliminary operating the hydraulic equipment, check again the transmission oil level of the tractor.

Before removing hydraulic pipes or hoses and other parts, make sure to check that hydraulic pressure is relieved completely. The leaks of pressurized oil can cause a fatal physical injury.

Use proper protection equipments, before servicing hydraulic system.

Before connecting or disconnecting the hydraulic quick coupler, lower the implements to the ground, and check that hydraulic pressure is relieved.

To get the best performance, comply with the followings.

DO NOT start or stop the tractor suddenly.

DO NOT operate heavy loaded work and do not increase the engine rpm to high speed suddenly.

Despite warm ambient temperature, warm up the engine for about 5 minutes at low idle rpm.

Use the lower gear ratios when pulling heavy loads and avoid continuous operation at constant engine speeds. You will save fuel and minimize engine wear by selecting the correct gear ratio for a particular operation

Avoid prolonged operation at either high or low engine speeds without a load on the engine.

Check the instruments frequently and keep the radiator and oil reservoirs filled to recommended levels. Daily checks include the engine oil level, radiator coolant, and air cleaner.

After using the first 50 hours, be sure to perform the maintenance items listed in the maintenance schedule. Refer to the chapter 5-4, “First 50 hour check” in this manual. If possible, contact your authorized local dealer for “First 50 hour check”.

Check if there is some other people around before starting.

Place all the levers and switches in NEUTRAL or OFF position.

Pull the throttle lever backward to reduce the engine speed and turn the key switch to “OFF” position. The engine shall be stopped.

Remove the ignition key after stopping engine.

To stop the engine after finishing heavy work, run the engine for about 2 minutes at the low idle rpm. If you stop the engine suddenly, the engine life could be reduced.

The tractor hydraulic oil also serves as the tractor transmission fluid. During cold weather operation, the hydraulic oil viscosity increases. This increase in oil viscosity restricts the oil’s ability to flow and lubricate in the transmission and hydraulic circuits. The cold oil can result in abnormal noises and slower operation times due to the increased oil viscosity.

A warm up time at 50% rated engine speed is recommended to assure proper vehicle functionality, transmission lubrication and operation.

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

During the warm-up operation, do the following: Engage the parking brake, set all shift levers to their NEUTRAL positions, and place the Power Take-Off (PTO) clutch lever in the OFF position. Failure to comply could result in death or serious injury.

Recommended Warm-Up Time:

1. Lift up all the implements (front/middle/rear) from the ground after starting engine

2. Set the engine speed more than 1500 rev/min.

3. Place the range gear shift lever on a suitable position.

4. After pressing down the brake pedal, release the parking brake.

4. Plug in charger cord.

5. Charge battery with a “SLOW CHARGE”.

6. Check the charging current and temperature of electrolyte during the charging.

7. Unplug charge cord and remove charger cables.

8. Attach battery to the tractor.

Put on eye protection and globes to protect human body from poisonous sulfuric acid before handling the battery.

Always remove grounded (-) battery clamp first and assemble it last. If not, it can cause explosion by spark.

Keep all flames and sparks away and DO NOT smoke while charging the battery.

Detach battery from the tractor before charging. DO NOT charge directly while the battery is attached to the tractor.

Turn off or unplug the charger cord, before connecting or disconnecting the charger cable to or from the battery.

Charge the battery in an area with good ventilation.

Do not charge the frozen battery.

Use the rated 12V-5A charger.

Never check battery charge by placing a metal object across the terminals.

If the battery which is attached to the tractor is discharged and needs to connect a auxiliary battery, follow the instructions as below.

Connecting Jumper cables

• Check followings before connecting the cables.

– Is the spring of clamp normal?

– Is the cable and clamp cut-off?

1. Stop engine, apply parking brake and remove the ignition key.

2. Connect two (+) terminals of both batteries with red cable. (tractor battery, auxiliary battery)

3. Connect one end of black cable to (-) terminal of auxiliary battery and the other end to engine block desired to start.

4. Start engine. If the engine does not start, check the electrolyte level of each battery.

The gas generated from the battery can be exploded by spark. DO NOT connect the negative(-) cable of auxiliary battery to the negative (-) terminal of tractor battery. Make sure to connect to the engine block.

Keep all flames and sparks away and DO NOT smoke while charging the battery.

Removing Jumper cables

Remove jumper cables as referring to the right figure, “Removing order of jumper cables”.

Pay attention not to change the (+) and (-) pole. If not, it may cause a failure of electric circuit or the damage of wire and even the polarity of battery can be changed at over-discharged state.

The tractor alternator (1) is belt-driven from the engine crankshaft pulley. It is important that belt slippage does not occur, or the charging system will be affected. To adjust the fan belt, see page 5-31.

Required alternator periodical maintenance:

• Belt adjustment
• Inspect alternator terminals
• Clean alternator cooling fan fins

When working on or checking the alternator, adhere to following precautions or alternator damage may occur:

• Do not UNDER ANY CIRCUMSTANCES short the field terminal of the alternator to ground.
• Do not disconnect the alternator output lead or battery cables while the alternator is operating.
• Do not remove the alternator from the tractor without first disconnecting the negative (-) battery cable. When removing the battery, disconnect the negative (-) cable first.
• To install a battery, MAKE SURE that the positive (+) cable is connected first and that the negative terminal is connected to ground. Reverse polarity will destroy the rectifier diodes in the alternator.

If the battery charge warning indicator illuminates, indicating that the alternator is not charging the battery, check the fan belt and the wiring connections. If these items are in satisfactory condition and the warning light continues to indicate no charge, contact your authorized local dealer.
