Engine fuel, maintenance of fuel filters and fuel storage

In order to meet the emission control regulation of 3rd-stage, the engine components have been made precisely and

they are to be used under high-pressure conditions.

Therefore, the specified fuel must be used for the engine.

As a matter of course, not only the guarantee will not be given for the use of a fuel other than the specified but also it

may invite a serious breakdown.

In addition, since suitable specifications for the fuel filter elements have been established for this engine, use of the gen-

uine filter is essential.

The following describes the specifications and the requirements of the fuel to be applied, and maintenance of the fuel

and the fuel elements.

Fuel to be applied

Selection of fuel

Following conditions must be met for the diesel engines, that is the one;

1 In which no dust even fine one is mixed,

2 With proper viscosity,

3 With high cetane rating,

4 With good flow properties in lower temperature,

5 With not much sulfur content, and

6 With less content of carbon residue

Applicable standards for diesel fuel

If a standard applied to the fuel for the diesel engine is stipulated in your country, check the standard for details.

Requirements for diesel fuel

Although conditions required for the diesel fuel are illustrated above, there are other requirements exerting a big

influence on its service durability and service life.

Be sure to observe the following requirements for selecting fuel.

Sulfur content .............................................................................. 2500 ppm or less

HFRR* ......................................................................................... 460 mm or less

Water content .............................................................................. 0.05 wt% or less

* HFRR (High-Frequency Reciprocating Rig.): An index showing lubricating properties of the fuel.

Sulfur content reacts to moisture to change into sulfuric acid after combustion.

Use of a fuel containing much sulfur content allows it to accelerate internal corrosion and wear.

In addition, much sulfur content quickens deterioration of engine oil allowing its cleaning dispersive property to be

worse which results in acceleration of wear of sliding portions.

HFRR is an index that indicates lubricating property of a fuel.

Large value of the index means poor lubrication so that seizure of the machine components may result if such a

fuel is used.

Since a fuel with high HFRR value also has lower viscosity, it can easily be leaked out.

Applicable Standard Recommendation

JIS (Japanese Industrial Standard) NO.2

DIN (Deutsche Industrie Normen) DIN 51601

SAE (Society of Automotive Engineers)

Based on SAE-J-313C NO. 2-D

BS (British Standard)

Based on BS/2869-197 Class A-1

EN590

Lep SM700B1002-2EN Issued 04-2010

1002-8

If the fuel is mixed with the engine oil, the oil is diluted to deteriorate its lubricating property resulting in accelera-

tion of wear.

Water content allows inside of the fuel tank to rust which in turn blocking the fuel line and the fuel filter.

IMPORTANT : In cold weather, fill the fuel tank at the end of the day's work, in order to prevent the formation of conden-

sation.This may also cause wear and seizure of the machine components.

If atmospheric temperature goes below the freezing point, moisture content in the fuel forms fine particle of ice

allowing the fuel line to be clogged.

IMPORTANT : Obtain table of analysis for the fuel you are using from the fuel supplier to confirm that it meets the crite-

ria described above.

IMPORTANT : If a fuel which does not meet the specifications and the requirements for the diesel engine, function and

performance of the engine will not be delivered. In addition, never use such a fuel because a breakdown of the engine

or an accident may be invited.

Guarantee will not be given to a breakdown caused by the use of a improper fuel.

Some fuels are used with engine oil or additives mixed together with diesel engine fuel.

In this case, do not use these fuels because damage to the engine may result as the fuel has been contaminated.

It is natural that the emission control regulation of 3rd-stage will not be cleared in case where a fuel that does not

meet the specifications and the requirements is used.

Use the specified fuel for compliance of the exhaust gas control.

IMPORTANT : It you use diesel fuel which contains much sulfur content more than 2500 ppm, be sure to fol- low the

items below for the engine oil selection and maintenance of engine parts. Guarantee will not be given to breakdowns

caused by not to follow these items.

1 Selection of engine oil

Use API grade CF-4 or JASO grade DH-1.

2 Exchange the engine oil and engine oil filter element by the periodical interval reported on the Operator’s

Manual.

3 Inspect and exchange the EGR (*)parts and fuel injector parts of engine every 3000 hour of use.

* EGR: Exhaust Gas Recircultion

Maintenance of fuel filters

Be sure to use the genuine fuel filters.

The fuel injection system is precisely constructed and the genuine filter employs finer mesh than conventional fil-

ters to improve protection of machine equipment.

If a filter with coarse mesh is used, foreign object passing through the filter enters into the engine so that machine

equipment can wear out in a short period of time.

IMPORTANT : If a fuel filter other than the genuine filter is used, guaranty will not be applied to a fault caused by the

use of a wrong filter.

Two kinds of fuel filter, the pre-filter and the main filter, are mounted on the machine.

Be sure to use the genuine fuel filters and replace them at the periodic intervals reported on the operator’s Man-

ual.

IMPORTANT : Since the pre-filter also has a function of water separation, discharge water and sediment when the float

reaches lower part of the filter elements. CHECK EVERY DAY before to start the engine.

Time to replace filters may be advanced according to properties of the fuel being supplied.

• Therefore, take measures to prevent dust or water from being entered in the fuel tank when sup- plying fuel.

• When supplying fuel directly from a fuel drum can, leave the drum as it stands for a long period of time to supply

clean fuel standing above a precipitate.

• If it is hard to leave the drum for a long period of time, install a fuel strainer and a water separator before the fuel

tank of the machine to supply clean fuel.

Water drain cock is provided on the bottom side of the fuel tank.

• Drain water before starting the engine every morning.

• In addition, remove the cover under the tank once a year to clean up inside of the tank.

Fuel storage

Long storage can lead to the accumulation of impurities and condensation in the fuel. Engine trouble can often be

traced to the presence of water in the fuel.

The storage tank must be placed outside and the temperature of the fuel should be kept as low as possible. Drain off

water and impurities regularly.

Anti-freeze/Anti-corrosion

Use anti-freeze in all seasons to protect the cooling system from corrosion and all risk of freezing.

CASE/AKCELA: PREMIUM ANTI-FREEZE (MS 1710)

For areas where the temperature goes down to -38°C (-36.4°F), mix 50/50 with water.

IMPORTANT : Do not mix products of a different origin or brand. The same product must be used when topping up the

system.

Environment

Before carrying out any maintenance operation on this machine and before disposing of used fluids or lubricants,

always think of the environment. Never throw oil or fluid on the ground and never place it in leaking receptacles.

Contact your local ecological recycling centre or your CASE Dealer to obtain information on the correct method of dis-

posing of these lubricants.

Plastic and resin parts

When cleaning plastic parts, the console, the instrument panel, the indicators etc... avoid using petrol, kerosene, paint

solvents etc... Use only water, soap and a soft cloth.

The use of petrol, kerosene, paint solvents etc... causes discoloration, cracks or deformation of these parts.
