2 - SAFETY INFORMATION

Ecology and the environment Soil, air, and water are vital factors of life in general. When legislation does not yet rule the treatment of some of the substances required by advanced technology, sound judgment should govern the use and disposal of products of a chemical and petrochemical nature.

NOTE: The following are recommendations that may be of assistance: • Become acquainted with and ensure that you understand the relative legislation applicable to your country.

• Where no legislation exists, obtain information from suppliers of oils, filters, batteries, fuels, antifreeze, cleaning agents, etc., with regard to their effect on man and nature and how to safely store, use, and dispose of these substances.

Helpful hints • Avoid filling tanks using cans or inappropriate pressurized fuel delivery systems that may cause considerable spillage.

• In general, avoid skin contact with all fuels, oils, acids, solvents, etc. Most of them contain substances that may be harmful to your health.

• Modern oils contain additives. Do not burn contaminated fuels and or waste oils in ordinary heating systems.

• Avoid spillage when draining off used engine coolant mixtures, engine, gearbox and hydraulic oils, brake fluids, etc.

Do not mix drained brake fluids or fuels with lubricants. Store them safely until they can be disposed of in a proper way to comply with local legislation and available resources.

• Modern coolant mixtures, i.e. antifreeze and other additives, should be replaced every two years. They should not be allowed to get into the soil, but should be collected and disposed of properly.

• Do not open the air-conditioning system yourself. It contains gases that should not be released into the atmosphere.

Your CASE CONSTRUCTION dealer or air conditioning specialist has a special extractor for this purpose and will have to recharge the system properly.

• Repair any leaks or defects in the engine cooling or hydraulic system immediately.

• Do not increase the pressure in a pressurized circuit as this may lead to a component failure.

• Protect hoses during welding as penetrating weld splatter may burn a hole or weaken them, allowing the loss of oils, coolant, etc.

• In hot cab air temperatures, open the doors and windows to replace the hot air before you turn on the air conditioner.

• When there is hot coolant temperatures, it is possible to heat the air with the coolant.

• For health reasons, do not over cool the cab. Periodically ventilate the cab.

NOTICE: Do not splash water on the control panel. Water can cause an unexpected failure.

NOTICE: Keep fire away from the air conditioner.

NOTICE: Adjust the air conditioner according to the ambient temperature and the weather conditions. The optimum difference between the ambient temperature and the temperature inside the cab is 5 to 6 degrees.

Precautions for inspection and maintenance for the air conditioner • To achieve the best performance, have your authorized dealer inspect and maintain the air conditioner.

• Your authorized dealer will use specific tools and instruments to refill the refrigerant gas and to service your air conditioner.

• Operate the air conditioner for two to three times a month (even during the off-season) to sustain the oil in the compressor.

• Check the refrigerant for gas leakage. If there is leakage over a period of time, rust will occur and cause a failure.

• When you clean in the cab, keep electrical components of the air conditioner parts away from water. Water will cause rust which will cause a failure.

6 - WORKING OPERATIONS

Practices to improve efficiency • Swinging the upper structure on a slope may cause the machine to overturn. On a slope, it is very dangerous to swing the upper structure downhill with a full bucket.

Prepare a level area for the machine to operate safely.

• Make sure the rotation area is clear of persons and obstacles before operating the engine.

NOTE: The optional attachments offer a wider range of application other than the showed ones.

Digging instructions Use mainly the arm force for digging. Use the full bucket rotation travel to fill it completely. Setting the bucket too deep will decrease the machine’s efficiency.

Maximum digging force position The attachment will provide maximum digging force when arm and boom are positioned at 90 - 110 ° from each other. Operate slowly to get maximum digging force.

Caution while using rubber crawlers Proper usage

Rubber belt

The rubber crawlers offer excellent features which steel crawlers do not possess.

However, if they are used the same way as the steel crawlers, then their advantages cannot be fully exploited.

Operation of the machine varies upon working site and conditions.

Although the rubber crawler offers many advantages thanks to the properties of its material, it also has disadvantages in terms of strength. As a consequence, it is necessary to be familiar with the characteristics of this kind of crawler.

Less vibration Smooth operation Low noise Harmless for paved road Easy handling Resistant Large traction force : Excellent : Good

: Normal

Rubber crawler warranty The warranty does not cover such damages to the rubber crawlers resulting from improper working or if their tension is inaccurate.

Forbidden operations Do not carry out the following operations: Do not travel nor work on following surfaces: gravel-mixed land, rugged and solid rock bed, reinforced concrete, steel plate edges.

LELI11E0259AA

Do not work in asphalt levelling.

When storing the machine for a long period (more than three months), keep it in a closed room where it will not be exposed to direct sunshine or rain.

When the machine travels only on one side of the crawler, and keeps the other side floating, the crawler may come off of the rollers or get damaged.

Precautions for use Use care of the following when working.

Rubber crawlers slip easily on icy surfaces.

Take the necessary safety precautions.

Avoid making a spin turn on concrete surfaces.

Avoid abrupt changes of direction as this will cause an early wear or damage of the rubber crawlers.

Mud and water adhering to the machine may freeze interfering with proper machine operation. Use the following general guidelines as reference to prevent malfunctions:

• Keep all belts properly tensioned.

• Make certain that the engine coolant mixture is sufficient to keep the machine safe.

• If the machine becomes overheated, idle the machine to help cool the engine, turn the engine off and check coolant level. After filling to proper level the machine continues to over heat, stop engine, allow to cool, drain and flush entire cooling system and refill with the proper mixture of fresh, clean coolant.

• Check the batteries electrolyte (acid) level frequently and fill as necessary with distilled water.

• Keep a close watch on the instrument cluster for warning icons during operation. Avoid unnecessary low speed running of the engine during operation. During slow, or no work periods, place throttle control lever to LO position.

Operation in high altitudes • Due to low atmospheric pressure at high altitudes, a decrease in engine power will be experienced. Be aware of this fact when placing machine under heavy load in high altitude climates.

• Keep close watch on the coolant temperature meter to avoid overheating of the engine.

Operation in sandy and dusty areas Air filter • Check the engine air filter element frequently in sandy or dusty conditions. Clean or replace the filter element at the corresponding intervals Radiator • Clean the radiator regularly to prevent the radiator core from becoming clogged with dust.

• Remove water and mud from the machine. Remove water adhering to the travel system thoroughly and park on dry ground to prevent the travel system from freezing.

• Retract the hydraulic cylinder rods as much as possible to reduce the exposed areas of the rods. This will prevent mud or water on the rod faces from damaging the seal.

Operation in extreme heat

Fuel • Be careful not to let contamination in the fuel when refuelling. Inspect the elements and filters at the corresponding interval.

Electrical equipment • Clean the starter and generator especially, at the corresponding interval, to prevent dust from accumulating.

Fitting with O-ring The O-ring (2), allows to insulate the oil pressure inside of hose (1) and to avoids oil spillages.

The tightening torque of the joint of each hydraulic hose (1) is determined by the diameter of the hose fitting thread.

If you notice a fault of operation, repair hose connection or replace it.

When connecting worn parts, pay particular attention to keep sealing surfaces clean from dirt and try not to damage them.

O-ring If the fitting is loose and oil leaks may occur, do not tighten it. It is necessary to install a new O-ring and to check again for tightness.

Never install a damaged and deteriorated O-ring even if it is new one. The use of an O-ring other the specified one, causes oil leakage and short life of hydraulic equipment.

Joint Be careful not to damage hoses, pipes or seal faces, this can impair the tightness.

Keep seal surfaces free from dirt.

Fitting with foreign matter inside causes oil leakage.

Hose Avoid high pressure hoses to twist during connection. Life of twisted hoses is drastically reduced.

Wash pipes and hoses, both inside and outside, with washing fluid and accurately dry them before reconnection.

Biodiesel fuel Biodiesel usage in CASE CONSTRUCTION products Introduction to Fatty Acid Methyl Ester (FAME) biodiesel FAME biodiesel, called biodiesel fuel in the following section, consists of a family of fuels derived from vegetable oils treated with methyl esters.

There are two main biodiesel fuel types: Rapeseed Methyl Ester (RME) and Soybean Methyl Ester (SME).

RME is a blend of rapeseed and sunflower methyl ester, and is the preferred crop in Europe. SME is the preferred crop in the United States.

Biodiesel fuel is a renewable alternative fuel source. Its use and development is promoted worldwide, especially in Europe and in the United States.

NOTICE: Your emissions control system is compatible with up to 20 % biodiesel fuel (B20). Be aware that the use of biodiesel fuel that does not comply with the standards mentioned in this section could lead to severe damage to the engine, fuel system or aftertreatment system of your machine. The use of non-approved fuels may void CASE CONSTRUCTION Warranty coverage.

Biodiesel fuel can be used to run diesel engines as pure biodiesel fuel or when blended with standard diesel fuel: • B5: indicates the blend of 5 % biodiesel and 95 % diesel fuels.

• B7: indicates the blend of 7 % biodiesel and 93 % diesel fuels.

• B20: indicates the blend of 20 % biodiesel and 80 % diesel fuels.

• B100: indicates pure biodiesel, or 100 % biodiesel fuel.

Do not use.

Biodiesel fuel has several positive features in comparison with diesel fuel: • Biodiesel fuel adds lubricity to the fuel, which is beneficial in many circumstances, particularly as sulfur and aromatics are removed from the fuel.

• Biodiesel has a greater cetane number and burns cleaner.

• Biodiesel produces less particulate matter and reduces smoke emissions.

Biodiesel blends are covered by: • United States Diesel Fuel Specification ASTM D6751-09A allows up to 5 % biodiesel since 2009.

United States fuel suppliers are allowed to use up to 5 % biodiesel fuel (B5) to supply the network.

• United States Biodiesel Fuel Specification ASTM D7467-09A provides specifications for diesel and biodiesel blends from B5 to B20.

Pure biodiesel (B100) specification is covered by the following requirements: • ASTM D6751-09A - Standard specification for biodiesel fuel blend stock (B100) for middle distillate fuels.

NOTE: ASTM D6751 specification has been updated to improve the quality of biodiesel in the market place.

Before raw oil can be converted into usable biodiesel fuel, it must undergo transesterification to remove glycerides. During the transesterification process, the oil reacts with an alcohol to separate the glycerine from the fat or vegetable oil. This process leaves behind two products: methyl ester (the chemical name for biodiesel) and glycerine (a byproduct usually sold for use in soaps or other products).

NOTICE: Biodiesel fuels approved for use in the CASE CONSTRUCTION equipment must be transesterified and comply with the North America Standard ASTM D6751.

NOTICE: Cold Pressed Biodiesel, Cold Pressed Oil, Straight Vegetable Oil (SVO), or more generally unrefined vegetable oils used as motor fuel, are fuels that are normally made from Rapeseed oil or similar high oil content crops. These kinds of fuel are not transesterified, so they do not fulfil the ASTM D6751 requirements. There is no recognized quality standard available for these types of fuel. Therefore the use of Cold Pressed Biodiesel, Cold Pressed Oil, Straight Vegetable Oil (SVO), or more generally unrefined vegetable oils used as motor fuel are NOT APPROVED at any blend in any CASE CONSTRUCTION product.

NOTICE: Any engine and fuel injection equipment fitted to a CASE CONSTRUCTION vehicle found to have run with any blend of NON-APPROVED fuel (fuel not fulfilling the specification described in the requirement ASTM D6751) will no longer be covered for Warranty by CASE CONSTRUCTION.

Biodiesel fuel usage conditions

• Biodiesel is fully biodegradable and non-toxic.

You must stringently follow the biodiesel fuel usage conditions. Incorrect application of the biodiesel fuel usage conditions could lead to severe damage to the engine, fuel injection equipment and aftertreatment system.

Diesel and biodiesel fuel specifications Tier 4a diesel fuel specifications are covered by the following: • ASTM D975-10, Standard Specification for Diesel Fuel Oils. (15 ppm sulfur maximum.)

The main concerns related to operation with biodiesel fuels are:

7-10

7 - MAINTENANCE

• Filters and injector blockage caused by poor fuel quality.

• Wear and corrosion of internal components due to water content, which affects lubricity.

• Deterioration of some rubber sealing compounds in the fuel system.

• Biodiesel oxidation, which can lead to the formation of deposits that can harm the fuel injection system.

NOTICE: Any problem in the engine fuel injection equipment associated with non-compliance to the following conditions for biodiesel fuel handling and maintenance will not be covered for Warranty by CASE CONSTRUCTION. Purchase biodiesel fuel from a trusted supplier who understands the product and maintains acceptable fuel quality. It is highly recommended that you use biodiesel from BQ 9000 accredited suppliers to maintain the quality and consistency of the fuel. The BQ 9000 Quality Management Program is accredited by the National Biodiesel Board for producers and marketers of biodiesel fuel. See the National Biodiesel Board website at www.biodiesel.org for more information.

The use of biodiesel blends above B5 through B20 will not void the CASE CONSTRUCTION warranty as long as the following conditions for biodiesel fuel handling and maintenance are stringently followed: Biodiesel fuel must be pre-blended by the supplier. Mixing biodiesel fuels on-site can result in an incorrect mixture that could damage the engine and/or fuel system.

NOTICE: For machines using Tier 4a engines with an exhaust aftertreatment system in regions where the biodiesel blend stock is supplied to the ASTM D6751-09A standard, it is essential that evidence of compliance to the special limits for Group I Metals, Group II Metals and the reduced phosphorus content specified above be obtained on every delivery of fuel from the fuel supplier. Failure to comply with this requirement can result in damage to the catalyst of the aftertreatment system which will not be covered under warranty.

NOTICE: CASE CONSTRUCTION may void your warranty if the problem is associated with poor fuel quality due to improper blending. It is the responsibility of the fuel supplier and/or yourself to ensure the right type of fuel and blend is delivered and used.

Maintenance intervals For machines using the all electronic engines with a high pressure common rail fuel system, the engine oil and filter change interval is reduced to 250 h when using biodiesel blends greater than B5 up to B20. Please refer to the maintenance intervals specified in the Operator Manual for all engines.

Check all hoses, connections and gaskets to ensure integrity and cleanliness every 3 months or 150 hours of operation, whichever comes first.

Regular oil sampling is highly recommended to monitor for oil and engine deterioration.

For machines using Tier 4a engines with an exhaust aftertreatment system:

NOTE: Oil sampling kits are available from your authorized CASE CONSTRUCTION dealer.

1. If the biodiesel blend stock to ASTM D6751-09A is used, special precautions need to be taken to insure that it fully complies with the following special requirements:

When switching back from biodiesel to regular #2 diesel, all fuel filter, oil and oil filter should be changed even if this falls between routine service intervals.

• Group I Metals content (Sodium + Potassium) is ≤ 5 mg/kg per EN14538 as specified in the biodiesel spec.

• Group II Metals content (Calcium + Magnesium) is ≤ 5 mg/kg per EN14538 as specified in the biodiesel spec.

• Phosphorus content lower than specified is a mandatory requirement. Phosphorus must not exceed 4 mg/kg per ASTM D4951.

2. The resulting greater than B5 through B20 blend must not exceed 1 mg/kg for Group I Metals (Sodium + Potassium) and for Group II Metals (Calcium + Magnesium).

Storage The machine should not be stored for more than three months with biodiesel in the fuel system. For longer storage time, it is strongly suggested that only regular #2 diesel fuel is used.

NOTE: If storage for longer than 3 months is necessary, the engine must be run on regular #2 diesel for a minimum of 20 h to flush the biodiesel fuel out of the fuel system prior to storage.

Biodiesel is highly hygroscopic and tends to collect water more than diesel fuel. This increases the risk of algae and bacteria growth which can cause severe damage to the fuel injection system. Keep the machine fuel tanks and on-site storage tanks as full as possible to limit the amount of air and water vapors inside the tank. Drain water from the tanks at least once a week.

NOTICE: Do not use biocide additives on Tier 4a engines with an exhaust aftertreatment system.

Use of biodegradable oils When you use biodegradable oil, please refer to following: • There are two types of biodegradable oil available: vegetable-based and synthetic-based. We recommend using synthetic oils, because vegetable ones have a maximum operating temperature of 80 °C (176 °F). For this reason, the degradation of vegetable-based oil occurs more rapidly, and they have a reduced service life.

• Do not mix bio-oil with original factory-filled mineral oil; in case it is necessary to use bio-oil, flush the hydraulic system that was filled with bio-oil three times.

• If you use bio-oil, the performance of the rotation brake and that of the parking/travel brake will be reduced, because of the lower friction factor of bio-oil compared to that of mineral oil.

• For further information about the type of biodegradable lubricant and the relevant specifications for use and maintenance, please refer to chapter ACCESSORIES.

Use of coolant • There are two types of coolant depending on the corrosion inhibitors base: ORGANIC-base and INORGANIC base.

• Both type can be used, BUT THEY CANNOT BE MIXED. Flush the cooling system before change coolant type.

Replacing fuses The spare fuses are stored in the fuse and relay box. A blown fuse must be replaced with a fuse with the same capacity or it may cause damage to the electrical system.

If fuse replacement is frequent, it may be caused by a failure in the electrical system. Contact your authorized dealer.

NOTICE: The ignition switch key must be turned to the OFF position before you replace a fuse.

The main fuse box is positioned under the seat stand cover.

1. Lower to bucket to the ground.

2. Place the safety lock lever in the LOCKED position.

3. Turn the ignition switch key to the OFF position.

4. Use the ignition switch key to unlock the cover. (2).

5. If the fuse box cover (1) is locked, unlock it.
