Also, check for abnormal vibration from the engine, noise, and the conditions of smell and color in the exhaust gas.

4.3.1. AUTOMATIC WARM-UP OPERATION

If the hydraulic oil temperature and the engine coolant temperature are low, the control system will start automatic warm-up operation. This will be observed particularly in cold weather operations. Warm-up is necessary to prevent damage to the hydraulic system and the engine.

Proceed with the following steps for warming:

Important

If abnormal sounds, excessive vibration, or abnormal operation occurs, turn the key to OFF position immediately to stop the engine.

1. After starting the engine, “Engine Warm Up” message appears on MED to indicate that the engine cooling system and hydraulic system is warming-up. Message displays until the temperatures reach minimum required values.

2. While engine is automatically warming-up, the engine rpm is gradually increased to 1200 rpm and cannot exceed this value until the system is warm enough.

3. Engine warm-up operation may take up to 15 minutes depending on the external temperature.

4. In case it is necessary for emergency or maintenance needs, operator may cancel preheat function by pressing 3 seconds auto warm up stop switch to cancel pre-heat.

4.3.2. WARMING-UP HYDRAULICS

1. Lower the left control console to release the safety locking system,

2. Raise the bucket from the ground.

3. Slowly move attachments without a load for five minutes, swing clockwise / counterclockwise a few times, to circulate the oil through the system. Travel forward and reverse at low speed for about two revolutions of the drive sprocket.

4. If any abnormal operation such as delayed response occurs in any operation, warm up the hydraulics as described.

WARNING

The SAFETY LOCK LEVER must be pushed in LOCKED position to prevent machine controls from an accidental movement.

When the safety lock lever is at straight position, the safety locking system is UNLOCKED. Make sure to rotate safety lock lever down to correctly engage the LOCKED position.

See chapter 3.15. "SAFETY LOCKING DEVICE".

IMPORTANT

Never operate the control levers with higher stroke when the hydraulic oil temperature is low. Always perform the warm-up procedures to raise hydraulic oil temperature.

4.4. INSPECTIONS AFTER STARTING THE ENGINE

After warming up, check whether the gauges, warning lamps and pilot lamps are as in the following.

4.4.1. “ENGINE OIL PRESSURE IS LOW”

WARNING LAMP

Status: OFF

After the engine is warmed up, confirm that the engine oil low indicator is turned off.

CAUTION

Since the oil pressure is low immediately after the engine is started, take measurements after the engine is warmed up.

CAUTION

For the following cases, immediately stop the engine, check the oil level and inspect for an oil leakage: The oil pressure warning light flashes or comes on

When the oil level is normal and no oil leak is found, a failure in the hydraulic system can be suspected. Promptly consult a Hidromek Authorized Service

4.4.2. ENGINE WARNING LIGHT

Status: OFF

CAUTION

When the failure indicator light comes on, or the engine failure code is indicated in the liquid crystal display (LCD) on the actual machine, promptly contact a Hidromek Authorized Service.

4.4.3. BATTERY CHARGE WARNING LAMP

Status: OFF

CAUTION

Make sure to confirm that the alternator warning light turns off.

4.4.4. ENGINE TEMPERATURE GAUGE

Status: NORMAL

4.4.5. HYDRAULIC OIL TEMPERATURE GAUGE

Status: NORMAL

4.4.6. FUEL LEVEL GAUGE

Status: NORMAL

4.4.7. AIR CLEANER IS CLOGGED INDICATOR

Status: OFF

4.4.8. AUTO WARM UP INDICATOR

4.4.10. REDUCED ENGINE POWER INDICATOR

LIGHT

Status: OFF

4.4.11. PARKING INDICATOR

Status: OFF

4.4.12. LOW BRAKE PRESSURE

Status: OFF

4.4.14. ABNORMAL NOISE OF ENGINE AND COLOR OF EXHAUST SMOKE

CAUTION

Immediately after the engine is started, the engine sound is louder compared to the sound after the engine is warmed up, and also the color of the exhaust smoke becomes more whitened or more blackened than the smoke discharged during the normal operation. The engine sound and the color of the exhaust smoke turn to normal after the engine is warmed up.

During urea SCR system purging and its cancellation, the sound may change, but this does not indicate a failure.

If an abnormality is found in the engine sound or the color of the exhaust, immediately contact a Hidromek Authorized Service.

4.4.14.1. ABNORMAL NOISE OF ENGINE

Listen to the engine sound carefully, and if an abnormal noise is heard, check the engine and identify the possible cause.

4.4.14.2. COLOR OF EXHAUST SMOKE

Check the combustion state of the fuel and the urea SCR system condition by observing the color of the exhaust smoke.

After the engine is warmed up, the color of the exhaust smoke becomes as follows without any load applied.

Also, inspect the exhaust pipe for leakage.

CAUTION

During urea SCR system purging, white smoke may be emitted temporarily, but this is not a failure.

When the engine is started in a low temperature, moisture vapor may be generated temporarily, but this is not a failure.

4.4.15. BRAKE TEST

Perform brake test as told in the chapter 3.24.3

4.4.13. AXLE LOCK INDICATOR

Status: OFF

4.4.16. COOLANT TEMPERATURE

Both too high and too low temperatures of the coolant can cause an engine malfunction. The temperature in the range of approx. 75~90°C (167~194°F) is suitable.

When the engine coolant temperature gauge reads a value exceeding the appropriate temperature, or when the coolant temperature warning light comes on, a dangerous condition of substantially heated engine can be suspected.

When the temperature of the coolant exceeds the appropriate temperature, the fuel flow is restricted. After stopping the machine operation, decrease the engine speed to the level equal to the idling speed, and then confirm that the coolant temperature has dropped to the appropriate temperature before stopping the engine.

Caution

Avoid stopping the engine when it is overheated. Operating the engine for a long period of time with a low coolant temperature not only increases the oil and fuel consumptions but also accelerates the engine wear, resulting in an engine failure.

4.4.17. HOUR METER (CUMULATIVE OPERATING HOUR COUNTER)

The cumulative time during engine operation is counted. Confirm that it is always operating while driving. Perform inspection and maintenance on each part in accordance with the time count displayed in this hour meter.

CAUTION

The hour meter cannot be reset.

4.4.18. BE CAREFUL WITH THE TOO COLD ENGINE

When the engine is too cold, in addition to engine wear, it will also deteriorate fuel economy. While operating the machine, when the coolant temperature does not reach the appropriate temperature (approx. 75 - 90 °C (167 - 194 °F)) indefinitely, take an appropriate action such as inspecting or replacing the thermostat.

4.4.19. WHEN THE WARNING LIGHT COMES ON

4.4.20.

When The Engine Coolant Is Hot

Do not loosen or remove the radiator cap. Doing so would be dangerous because steam and hot air will spurt out.

Caution

It is dangerous to ignore the warning light and continue operating the machine. Perform an inspection and take appropriate actions. When the meter shows an abnormality, take necessary actions.

4.5. OPERATING THE MACHINE

4.5.1. FORWARD TRAVEL WARNING

Make sure to read and understand all operating controls, Cautions, and Warnings before traveling.

Obey all traffic rules and regulations. Do not travel faster than conditions allow.

Before putting the machine into gear, make sure in which direction the machine is facing. Locate the front section of the excavator and select the appropriate gear for the direction of travel desired.

Before moving, make sure that there are no personnel in the way or on the machine. Sound the horn to alert workers that you are above to move the machine.

Be sure the path is clear during travel, especially when traveling in reverse gear.

If an alarm buzzer sounds or a warning light turns “ON”, stop machine and determine the cause of the problem.

If an unusual sound or smell is noticed, immediately stop the machine and determine the cause of the problem. Avoid sudden stops or turns. The machine is top heavy. Make sure to make turns at a slow speed.

Take extreme caution when traveling on road shoulders or narrow streets.

Before leaving the operators seat, make sure to lock out all control systems and shut down the engine to avoid accidental activation.

4.5.2. BEFORE TRAVELING

1) Raise the outrigger and dozer blade and make safe.

2) Before putting the machine into gear, make sure in which direction the machine is facing. Locate the front section of the excavator and select the appropriate gear for the direction of travel desired

3) Before moving the excavator, make sure that the swing lock pin has been engaged. This will prevent the excavator from accidentally rotating during traveling.

4) Before traveling make sure that axle lock switch is set to the OFF position.

5) Set the mode selection switch in the “T”, travel position.

Warning

The SAFETY LOCK LEVER must be pulled in LOCKED position to prevent machine controls from an accidental movement. The operator must lock the safety lever before he leaves the operator’s seat and especially during maintenance and repair work unless it is necessary to operate the machine for this purpose. If not, an accidental movement of any control lever will cause the machine or an attachment to move, and will cause serious injury or death.

4.5.3. TRAVELING PROCEDURES

1. Make sure that “Brake System Failure Indicator Light”, buzzer and “Low Brake Pressure” message is off.

2. After making sure the front attachment is facing forward, set the mode selection switch in the “T”, travel position.

3. Using the FNR Switch, select forward or reverse travel direction and step on the accelerator pedal.

4. Test the brakes before beginning over the road travel.

5. During forward motion you can shift from speed range 1, to speed range 2 with using FNR Switch on the steering console. Downshifting from speed range 2 to speed range 1 should not be done if the machine is traveling at high rate of speed. Damage to the transmission could result.

6. To stop the machine, release slowly the accelerator pedal. The dynamic braking action of the machine’s momentum against the engine’s backpressure will begin to slow the machine. Step on the brake to bring the machine to stop.

Important

Never drive down a slope with speed range 2; otherwise dynamic braking action of the machine’s momentum will be insufficient. Drive down a slope with a speed range 1 and low speed traveling position. It can be impossible to stop the machine when brake failure is occur.

7. After traveling a long distance, front attachment, outriggers or dozer blade may begin to drift due to normal internal hydraulic leakage. Position the machine in a safe location and reposition the front attachment, outriggers or dozer blade.

4.5.4. PARKING PROCEDURE

1. Slowly release the pressure on the accelerator pedal.

2. Step on the brake to fully stop the machine.

3. Move the FNR Switch to the “N”, neutral position.

4. Reduce the engine speed to idle level from the instrument panel.

5. Lower the bucket and the dozer blade to the ground.

6. Pull the safety lock lever.

7. Move the mode selection switch to “P” park mode.

8. Shut the engine down.

9. If the machine is parked on a slope, insert the wheel chocks on the downhill side of the wheels to secure the machine.

NOTE:

As the brake pedal is applied and if it is pressed all the way to the floor, a mechanical lock will engage and hold the pedal in the fully applied position.
