TLE4550 DPF REGENERATION

CAUTION : When automatic regeneration has to be suspended for some reasons just like in a green house or indoor that cannot ventilate well, press DPF regeneration inhibit switch, 3, for 3 seconds to stop automatic regeneration on the spot with lighting DPF regeneration inhibited lamp , 4, on. After stopping automatic regeneration by pressing this switch, keep away from DPF due to its temperature is too high for a while.

DPF (Diesel Particulate Filter) is equipped for collecting PM (Particulate Matter) contained in exhaust gas.

When the engine electronic control unit (ECU) detects a specified amount of PM, “DPF regeneration” is required.

NOTE: DPF regeneration has two types which are “automatic regeneration” and “manual regeneration”. Automatic regeneration is conducted automatically during operation.

Manual regeneration is conducted by pressing DPF manual regeneration switch while the machine is parked. Depending on the soot amount, either automatic regeneration or manual regeneration will be required.

When the soot amount is in the initial stage (soot amount from 80 to 100%), automatic regeneration will be conducted. If automatic regeneration is not conducted and soot amount increases (over 100%), manual regeneration will be required.

NOTE: If desired inhibiting automatic regeneration, press DPF regeneration inhibit switch for 3 seconds after starting the engine. Then, automatic regeneration will not start during operation.

After restarting the engine, automatic regeneration inhibit mode is cleared. Therefore, if desired inhibiting automatic regeneration, press DPF regeneration inhibit switch for 3 seconds again.

Normal Mode

Manual Regeneration Mode (stage 1)

There are no restrictions on the machine operation. DPF regeneration requested lamp, 1, is not illuminated.

When the DPF regeneration requested lamp is blinking and the buzzer sounds, the amount of soot increased because automatic regeneration was not performed or was insufficient. The machine needs to be parked and the manual regeneration is required.

Automatic Regeneration Mode

Stop the machine in a safe parking place and apply the parking brake to activate the brake switch, return the hand throttle lever to low idle, and push DPF manual regeneration switch, 5, for 3 seconds to start manual regeneration.

The regeneration procedure is started automatically and takes approximately 30 minutes to complete.

If the engine is turned off during the regeneration procedure and the accumulated soot still exceeds a certain amount, then the regeneration procedure continues when the engine starts again.

OPERATION STOPPING TRACTOR

Unlatch brake pedals and use as required to assist turning.

To stop the tractor, move hand throttle lever, 1, rearward, to reduce engine speed and slow travel.

Depress clutch pedal, 2, and brake pedals, 3 and 4, to stop. Put range gearshift lever, 5, and main gearshift lever, 6, and forward / reverse lever, 7, to the neutral position.

Always park tractor on level area whenever possible and apply the parking brake. If hillside parking is necessary, securely block both rear wheels as shown.

NOTE: When parking tractor, be sure the tyres are locked.

When traveling on road or operating at high speed, brake pedals must be latched together with interlocking plate, 8, so both brakes will apply at the same time.

CAUTION: Do not use individual wheel brakes, and latch brake pedals together using interlocking plate when traveling on roads or operating at high speed. Make sure brakes are adjusted evenly.

Pull up parking brake lever, 9, up firmly.

Allow engine speed to idle several minutes to allow even cooling. Then turn the main switch to “OFF” position shutting off engine. Lower 3-point hitch and remove the key from main switch.

FIG. 5-26 To engage differential lock, depress the clutch pedal and allow all rear wheel movement to stop. Depress the lock pedal and slowly engage the clutch.

3

4

To disengage differential lock, depress the clutch pedal and release differential lock pedal. The differential lock pedal should normally return to “OFF” position.

FIG. 5-24

IMPORTANT: Stop the tractor before engaging the differential lock.

NOTE: Brake pedals, 3 and 4, may be used independently to operate respective brake and assist turning at low speed operation.

37

TLE4550 NOTE: On occasion, differential lock pedal may remain engaged due to torque difference exerted by the rear wheels. In this case, operate the tractor slightly in forward and reverse. Tap the brake pedals alternatively while tractor is slowly in motion to release differential lock.

IMPORTANT: Always disengage front axle drive when operating in conditions with minimal wheel slippage (DRY OR HARD SURFACES).

If tyre replacement is necessary, identical replacements must be installed to maintain correct front / rear axle ratio.

CAUTION: When the differential lock is engaged, steering ability of the tractor will be greatly reduced. Disengage before attempting a turn. Do not use during traveling on road.

4-WHEEL DRIVE Tractor has a mechanically driven front axle. 4WD selector lever, 1, engages and disengages the drive for front axle.

With the lever pulled up, the front axle (4WD) is disengaged. With the lever pushed down, the front axle is engaged, and power is available to both front and rear axles.

FIG. 5-28

POWER TAKE-OFF (PTO)

1

CAUTION: Disengage the rear PTO and stop the engine prior to connecting equipment or disconnecting equipment from the tractor’s PTO shaft. Make certain the driver-shaft is securely locked in the annular groove of the tractor PTO shaft before starting the tractor engine.

DO NOT operate tractor without a PTO cap installed. The cap protects people from injury as well as the splines from damage.

FIG. 5-27 IMPORTANT: Stop the tractor before engaging or disengaging 4-wheel drive. Do not use 4WD on hard surfaces. Rapid wear of the front tyres and possible drive line damage could occur if 4WD is operated for prolonged periods on hard surfaces.

Before attaching, adjusting or working on PTO-driven implements, disengage the PTO, stop the engine and remove the key.

When the front axle drive is engaged, the ground speed of the front tyres will vary from that of rear tyres. This is to assist steering when 4-wheel drive is selected.

DO NOT work under raised equipment.

Before engaging a PTO-driven implement, ALWAYS carefully raise and lower the implement using 3-point linkage position control lever. Check clearances, PTO shaft sliding range and articulation.

When using a PTO-driven implement, make sure the universal joint does not interfere with the PTO shield cover.

For this reason, the front axle must be disengaged when the tractor is traveling on road or operating on a hard, dry surface. Failure to do so will result in rapid wear of the front drive tyres and possible driveline damage.

Ensure that all PTO safety shields are in place at all times. Do not step on the PTO shield cover.

38

OPERATION Mid PTO Shaft (option)

Ensure all PTO-driven implements are in good condition.

Mid PTO, 1, (6 splines, 35 mm (1-3 / 8”)) is a forwardfacing shaft located at underside of tractor. This accessory can be installed to operate certain mid or front-mounted implements.

NEVER step across any driveline. DO NOT use the PTO shield cover as a step.

NEVER use driveline as a step. NEVER wear loose fitting clothes. Keep at least your height away from a rotating driveline.

Mid PTO cap must be installed when mid PTO is not in use.

Normal mid PTO shaft operating speed: 2 000 min-1 @ 2 714 engine revolution speed

Rear PTO Shaft

CAUTION: Make sure all PTO safety shields are installed on tractor and equipment. Before cleaning or adjusting tractor or PTO driven machine, stop the engine, and DISENGAGE PTO.

PTO shaft, 1, (6 splines, 35 mm (1-3 / 8”)) provides power to rear-mounted PTO driven implement. PTO cap must be installed when it is not in use. Normal rear PTO shaft operating speed: 540 min-1 @ 2 430 engine revolution speed IMPORTANT: When the rear PTO is used with a 3-point mounted equipment, it may be necessary to remove rear hitch, 2, at rear of the tractor. Some types of mounted equipment, when lowered, the PTO shaft may contact drawbar, or implement drive shaft connected to the rear PTO shaft.

1 FIG. 5-31

1 2 FIG. 5-29 CAUTION: Make sure all PTO safety shields are installed on the tractor and equipment. Before cleaning or adjusting the tractor or PTO-driven machine, STOP THE ENGINE AND DISENGAGE PTO.

FIG. 5-33

Stationary PTO switch, 1, can engage and disengage the rear PTO.

NOTE: PTO can be engaged / disengaged by PTO switch, 1, independently from the main clutch. Reduce engine revolution speed prior to engaging and disengaging PTO. Always set the PTO switch to “OFF” position before shifting the rear or mid PTO selector levers.

Rear and mid PTO can be operated separately or together.

To engage rear PTO - Set all levers and switches in neutral position, and apply the parking brake.

• Seat on the operator’s seat.

• Start the engine.

• Set the rear PTO selector lever to 540 rpm position.

• Get off from the tractor and stand beside left side fender.

40

OPERATION • Press the stationary PTO switch for four seconds and release it.

the linkage has been raised when turning the tractor and traveling on roads.

NOTE: If the rear PTO does not start after pressing the stationary PTO switch for four seconds, try to press the PTO switch.

To disengage rear PTO - Push the stationary PTO switch and release it. Set the rear PTO selector lever in the neutral position.

1 FIG. 5-36 Draft Control Lever (option) - Draft control lever, 3, regulates linkage height to provide constant draft force of ground engaging implements (plows, subsoilers, etc.). Moving the draft control lever forward will provide deeper implements working depth. Moving the draft control lever rearward will provide a shallower depth. As soil conditions change, the system will raise or lower implements to keep even load to tractor.

FIG. 5-35 NOTE: Stationary PTO switch will not work for five seconds after the main switch is turned to “ON” position. However, engine needs to be started for starting stationary PTO switch.

CAUTION: When working on or around mounted implements, always lower them to ground prior to work. If an implement must be raised, always support the implement and the lower links securely.

CAUTION: Always disengage the PTO and stop the tractor engine before servicing any PTO-driven implement. Allow all movement and motion to stop before leaving operator’s seat.

3-POINT LINKAGE 3-point linkage combines the tractor and implement into one working unit. Implement positioning is controlled hydraulically. In addition, implement weight and loads impose downward pressure to the tractor rear wheels to increase traction.

NOTE: When starting the engine, make sure that the implement is lowered to the ground. This reduces load on the starter motor due to linkage trying to raise when the engine is cranked up by starter motor.

Position Control 3-Point Linkage Position Control Lever - 3-point linkage position control lever, 1, maintains the hitch position at constant height in relation to the tractor.

As the 3-point linkage position control lever is moved rearward, the linkage (and implement) are raised.

Moving the lever forward will lower the linkage to the selected position. Each lever setting provides a specific linkage (and implement) position.

Front lever stopper, 2, adjusts the implement lowering position.

TLE4550 Lowering Rate Control Knob - Lowering rate control knob, 4, controls the discharge rate of hydraulic oil and adjust lowering speed of the linkage and implement. Turn the knob clockwise to slow drop rate (increase lowering time), and counterclockwise to increase drop rate (decrease lowering time). Turning the knob fully clockwise will lock the implement in the raised position.

To match variety of implements, rear linkages standardized according to spacing, pin size, etc. This enables usage of different implements with minimal adjustment as long as matching size or “Category” is suitable for the tractor.

FIG. 6-10

FIG. 6-12 After changing the oil, sometimes the oil level gets low after running the engine. Check the oil level after test 57

TLE4550 running and make sure that there are no difference in oil level before and after the test run.

Thoroughly flush out the inside of the radiator with tap water.

Return the drain hose onto the pole and pour coolant into the reserve tank up to “FULL” level to fill the radiator.

COOLING SYSTEM

Securely close the radiator cap and reserve tank cap, and start the engine, allowing it to run for about 5 minutes in the mid speed range (approx. 1 500 min1). Then stop the engine.

CAUTION: Do not open the radiator cap except when checking or replacing the coolant. Make sure to allow the engine to cool sufficiently before opening the cap. If the cap is opened while the engine is hot, coolant can pour from the filler, resulting in a burn or other injury.

When the engine cools, the coolant in the reserve tank will be sucked into the radiator.

Add coolant to the reserve tank up to “FULL” level.

Checking / Replenishing Coolant The radiator is provided with reserve tank, 1, to maintain the coolant in the radiator at the proper level.

Check the level in this reserve tank during the daily inspection.

Open the hood, and make sure that the coolant in the reserve tank is between “FULL” and “LOW” levels. If the coolant level is near to “LOW” level, add coolant to the reserve tank up “FULL” level.

When the coolant level is below “LOW” level, remove radiator cap, 2, after allowing the engine to cool sufficiently. Add coolant and make sure that there is an adequate amount of coolant in the radiator.

FIG. 6-14

2

IMPORTANT: Do not fill the reserve tank higher than “FULL” level. This will prevent the radiator from functioning optimally, and may result in leakage of coolant.

2 3 FIG. 6-15 Use Of Anti-freeze

1

Freezing of the coolant may result in damage to the engine. Mix in 50 / 50 anti-freeze (Long Life Coolant), when the outside temperature will drop below 0 °C (32 °F) during the winter.

FIG. 6-13 Flushing Radiator / Replacing Coolant

The mixture ratio of anti-freeze differs depending upon the anti-freeze manufacturer and temperature. Follow the instruction for the anti-freeze.

Pull drain hose, 1, out from the pole at the right side of the engine to drain coolant. Open radiator cap, 2, at the same time to help the coolant to draining. Remove reserve tank, 3, to drain coolant from it.

LUBRICATION & PERIODIC MAINTENANCE FUEL SYSTEM

Water Draining From drain plug, 3, is attached to the pre-filter, drain the water immediately after the indicator lamp lights up. Also, periodically remove the filter bowl (case), to clean deposits of sediment or water, or inspect / replace the element.

Use only clean diesel fuel of correct grade. Introduction of water or dirt into the fuel tank or other portion of the fuel system can cause repeated clogging of the fuel filter and possible injection pump and injector damage.

Water drain procedure:

IMPORTANT: Do not use Kerosine or heavy oil as fuel. Do not add fuel additive. Do not use diesel after long-term storage in dram can or home tank. Usage of unspecified fuel causes break of fuel filter, parts of fuel injection or postprocessor.

• When water reaches specified level, indicates warning on the instrument panel.

• Clean area around the pre-filter.

• Shift cock lever, 1, to “OFF” position.

• Loosen bolt, 2.

• Drain water from the drain plug at the bottom of pre-filter.

• Tighten up the drain plug and bolt. (tightening torque of drain plug: 1 N.m; tightening torque of bolt: 8~10 N.m).

• Shift the lever to “ON” position.

Use only ultra-low-sulfur diesel. In case to use the fuel containing much sulfur, it will be cause of poisoning DOC and DPF. Then, DPF and DOC lose the functions of cleaning exhaust gas and raising temperature of the exhaust gas.
