6.2.2. RECOMMENDED LUBRICATION OIL

• The engine oil has a significant impact on the performance and service life of the engine, and fuel economy, so it is recommended to use the recommended oil specified by Hidromek. Any failure or accident which arises from use of inappropriate engine oil is excluded from the coverage of warranty.

• The engine oil has the following important functions:

- Prevents each part of the engine from wearing.

- Cools down each part of the engine.

- Cleans each part of the engine.

- Maintains airtightness of the combustion chambers and prevents rust generation. Replace the engine oil periodically.

CAUTION

Using fuel other than extra-low-sulfur diesel fuel (with sulfur content of 15 ppm or lower) may have a harmful effect on the engine and the exhaust gas purification device (urea SCR system), possibility resulting in a breakdown. If a wrong type of fuel is filled in, drain it completely. It is dangerous to start the engine with the wrong type of fuel filled in because doing so may cause a fire or engine damage. Open the fuel cap slowly. If the cap is opened quickly, the fuel may spurt out. Engine warranty is not applicable if any fuel except extra low sulfur diesel is used.

CAUTION

Engine oil lubricates and cools the engine interior components. The quality of the oil is degraded and the quantity of oil is reduced by evaporation, exhaust and combustion during the engine's operation. Continually using the same oil without checking the level or without replenishing and changing it could cause seizure or damage to the engine. Add or change the oil when the quality of the oil has degraded or the quantity is reduced, even if that occurs before expiration of the specified intervals in the maintenance schedule, which will differ depending on the conditions of use.

Fuel gradually gets mixed with the engine oil, causing the engine oil to become thin. Make sure to replace the engine oil at the specified intervals.

WARNING

Engine life and engine oil life will be affected by the quality and cleanliness of the fuel used. Make sure you know the quality of the fuel you are buying. If you are not sure, USE MINIMAL INTERVAL for oil change as specified below.

CAUTION

It is the responsibility of the user to monitor the actual condition of the engine oil. Perform maintenance (oil, fuel and air filters) according to the Maintenance Section (6.4) and follow recommendations made therein. It is extremely important to pay attention to type of fuel used and to CLEANLINESS.

6.2.3. RECOMMENDED FUEL

Use correct type of fuel that is recommended in this manual.

CAUTION

• Using fuel other than extra-low-sulfur diesel fuel (with a sulfur content of 10 ppm or lower for Japan and Europe, 15 ppm or lower for America) may have a harmful effect on the engine and the exhaust gas purification device (urea SCR), possibly resulting in a breakdown. If a wrong type of fuel is filled in, drain it completely. It is dangerous to start the engine with the wrong type of fuel filled in because doing so may cause a fire or engine damage.

• Any failure which arises from use of fuel other than extra-low-sulfur diesel fuel is excluded from the coverage of warranty.

• Open the fuel cap slowly. If the cap is opened quickly, the fuel may spurt out.

Caution

• For fuel of diesel engine, the following characteristics are required. Use a type of extra-low-sulfur diesel fuel designated for general diesel vehicles that is compliant with the following standards: Japanese Industrial Standards (JIS) K2204, American Society for Testing and Materials (ASTM) D975 No. 1-D S15 and No. 2-D S15, British Standards (BS) EN590, Deutsche Industrie Normen (DIN) EN590, Canada General Standards Board (CGSB) CGSB-3.517

- No fine dust is contained.

- Appropriate degree of viscosity is provided.

- High in cetane value.

- Good low-temperature fluidity.

- Low sulfur content.

- Low carbon residue.

•Besure touseextra-low-sulfur diesel fuel. Adding of or mixing with inferior fuel, water remover, other fuel additives, gasoline, heating oil, heavy oil or alcoholic fuel for use may cause a sliding failure of the fuel lubricating portions in the fuel filter and injector, and have harmful effects on each part of the engine which may result in an engine failure.

NOTE

• The specifications of diesel fuel vary depending on the season and the region.

WARNING

• Be sure to place the starter switch in the "OFF" position to shut down the engine before refueling the machine because refueling while the engine is running may cause a fire.

• When refueling, putting any flame nearby is strictly prohibited. Do not place a lighted cigarette or something similar nearby which may result in a fire.

• When refueling, take care not to spill the fuel. If any fuel is spilled, carefully wipe it away. Leaving as it is may cause the spilled fuel to be ignited, resulting in a fire.

Also, the cloths, papers, etc. used for wiping are easily ignitable. Dispose of them properly as flammable waste.

• When the fuel cap is not securely closed, the fuel may leak and cause a fire while driving.

Caution

• When dust or water mixes into the fuel, this may lead to an engine failure or accident. When adding the fuel to the fuel tank, take care not to let dust or water enter in the tank. When refilling directly from a drum can out of necessity, particularly be cautious to prevent foreign matters from entering into the tank.

• Add sufficient amount of fuel to the fuel tank, and periodically open the drain plug located at the bottom part of the tank to remove the sediments (dust and moisture) deposited at the bottom.

6.2.4. DIESEL EXHAUST FLUID(DEF/AdBlue®) Use DEF/AdBlue® specified by Hidromek. Use DEF/AdBlue® compliant with the following standards: JIS (Japanese Industrial Standards) K2247 standard defined for AUS 32, ISO (International Organization for Standardization) 22241 standard defined for AUS 32, the API (American Petroleum Institute) standards.

DEF/AdBlue® is a clear, colorless liquid. Do not use if there is color, as the DEF/AdBlue® mayhave deteriorated or been altered.

6.2.5. COOLANT WARNING

Use distilled water in the radiator. Do not use water from a well, river, sea, or brackish and waste water otherwise the cooling system maybe damaged.

If you add coolant to the system, use coolant in the same concentration with the coolant in the system.

When refilling coolant, flush out the system with distilled water.

Never mix different brands and different classes antifreeze. For example never mix standard life ethylene glycol antifreeze with extended life ethylene glycol antifreeze. If they are mixed, the protection level will be reduced.

Replace the engine coolant periodically. When only water is used as coolant, it can cause a serious damage in the cooling system because of lower freezing point, lower boiling point, and unfavorable corrosive properties. Therefore, add antifreeze when preparing coolant.

If it is not possible to have distilled water, the coolant water quality should comply with the following requirements.

The mixing ratio is determined according to the temperature, however to get minimum protection, at least 30% per volume is needed. When mixing antifreeze into coolant, determine the mixing ratio considering the lowest temperature expected. Set the freezing point at 10º C lower than the expected lowest temperature. Check the mixing ratio of antifreeze solution with the Baumé scale.

Values given in the table are water and antifreeze volumes in 1 liter of coolant. Multiply the values with the coolant capacity of your machine to calculate the total amount of water and antifreeze.

Eg: For protection of 39 liters coolant to -24 C. Volume of antifreeze is 39 x 0,4 = 15,6 L and volume of water is 39 x 0,6 = 23,4 L.

6.3. PERIODIC REPLACEMENT OF MAIN PARTS

To assure operational and working safety the user must perform maintenance of the machine and its components periodically as specified in the manual. Main parts and components listed in the following section must be replaced in their specified periods to secure max. safety and performance.

As the characteristics of these material deteriorate or the main parts wear out over time, it is hard to judge their condition just by periodical checks. Therefore, they should be replaced with the new ones at specified intervals, even though there are no apparent extraordinary abnormalities.

However, whenever any abnormality is found, replace them immediately. Also when you are replacing the hoses, if any damage is found on the hose clamps, replace the clamps as well.

Regularly, check hydraulic oil hoses in addition to the periodical replaced pads, if any abnormality is found, tighten or replace them.

When replacing the hoses, also replace O-Rings and gaskets.

For replacement of main parts, contact HİDROMEK dealer service centers.

Check the hydraulic oil hoses and fuel hoses periodically as follows:

When the coolant temperature is low.

3. Confirm that the engine speed increases smoothly and there is no knocking when accelerating gradually by operating the accelerator.

*: Inspection items that should be performed at an appropriate period determined based on the operation hours, driving conditions, etc. are indicated.

6.5.4. COOLANT LEVEL CHECK

Coolant reservoir tank has its own cover on the engine hood. It could be reached by opening the cover with its key.

WARNING

Do not perform any maintenance while the engine is running. Right after operating the engine, the coolant is very hot. Never open the radiator cap immediately after shut-down. Wait until it cools down, and then open the cap slowly to release the internal pressure. Hot vapor or boiling water may burst out and cause a burn. When removing the cap of the radiator or reserve tank, use a thick cloth to cover the cap and loosen it gradually.

Notes

Stop the engine before checking the coolant level and wait until it cools down. Coolant expands with temperature thus when the engine is hot, coolant level seems to be higher.

If the coolant level is abnormally low, there may be a leakage in the system. In this case, contact Hidromek Authorized Service and get checked the cooling system.

Inspect the radiator and radiator hose for a crack, damage and water leakage. Also, check whether a stain of water leakage is left on the ground surface where the machine is set. When a crack, damage or water leakage is found, contact a Hidromek Authorized Service.

WARNING

Use without fixing the water leakage can cause engine seizure.

Use specified amount of antifreeze-water mixture as coolant in all seasons.

Check the coolant level in the reservoir tank after the engine is cooled down. Fill the coolant reservoir tank to the maximum level.

Coolant and water specifications, mixing ratios Refer to  Chapter 6.2 "Oil, Fuel, Coolant and Diesel Exhaust Fluid”.

When an overheating problem occurs in your engine, refer to the Chapter "Troubleshooting" before adding coolant to the system.

WARNING

The coolant is toxic and must not be ingested. If the coolant is mistakenly ingested, immediately vomit it and seek prompt medical attention. When the coolant gets in your eyes, rinse it off immediately with a large amount of water for 15 minutes or longer. Also, if still an abnormality such as irritation is felt, seek medical attention. When the coolant gets on your skin, rinse it off using a soap with a large amount of water. Also, if an abnormality is observed, seek medical attention.

The coolant is flammable. Keep flames away from it. Also, the coolant could catch fire if it comes in contact with a hot surface, such as the exhaust manifold. Pay attention to prevent this from happening.
