1 - GENERAL INFORMATION

Introduction The excavator is a hydraulically operated machine. It consists of an undercarriage fitted with tracks and a swing bearing which supports the upper frame. The upper frame supports the attachment, the engine, the hydraulic components, the cab, the fuel tank and the counterweight. When the operator activates the controls (pedals/levers), the hydraulic pumps, operated by the engine, pumps the oil from the tank, sending it to the control valve which sends the oil to perform the requested operation. A cooling system maintains the hydraulic oil at normal operating temperature.

NOTICE: Do not use the excavator for operations which are foreign to its specifications and not included in this manual in order to prevent serious injury to persons or damage to the machine. The manufacturer/dealer is not responsible for damage caused by improper use.

The excavator has been designed to carry out digging and earth moving operations through the use of a bucket.

Operations that involve the use of hydraulic hammers or crushers are also possible. Other operations, such as moving suspended loads, are only possible if the specific variant approved by the manufacturer is present.

Using the excavator and its equipment for different operations, such as, for example, towing, transporting and lifting people, is considered inappropriate and is prohibited.

Biodiesel fuel - Biodiesel fuels Biodiesel usage in KOBELCO products

Biodiesel blends are covered by:

Introduction to Fatty Acid Methyl Ester (FAME) biodiesel

• European Diesel Fuel Specification EN 590 allows up to 7 % biodiesel since 2009. European fuel suppliers are allowed to use up to 7 % biodiesel fuel (B7) to supply the network.

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 Selective Catalytic Reduction (SCR) system is compatible with up to 7 % biodiesel fuel (B7). 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 and fuel system of your machine. The use of non-approved fuels may void KOBELCO Warranty coverage.

Biodiesel fuel can be used to run diesel engines as pure biodiesel fuel or when blended with standard diesel fuel: • B7: indicates the blend of 7 % biodiesel and 93 % diesel fuels.

• B20: indicates the blend of 20 % biodiesel and 80 % diesel fuels. Do not use.

• 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.

• United States Diesel Fuel Specification ASTM D6751-09A allows up to 7 % biodiesel since 2009.

United States fuel suppliers are allowed to use up to 7 % biodiesel fuel (B7) to supply the network.

• United States Biodiesel Fuel Specification ASTM D7467-09A provides specifications for diesel and biodiesel blends from B6 to B20.

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 KOBELCO equipment must be transesterified and comply with the European Standard EN14214 or 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 EN14214 or 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 KOBELCO product.

NOTICE: Any engine and fuel injection equipment fitted to a KOBELCO vehicle found to have run with any blend of NON-APPROVED fuel (fuel not fulfilling the specification described in the requirement EN14214 for Europe, or ASTM D6751 for the United States) will no longer be covered for Warranty by KOBELCO.

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 both the engine and the fuel injection equipment.

Diesel and biodiesel fuel specifications Tier 4a diesel fuel specifications are covered by the following: • Europe: EN 590 - Specification of Diesel fuel. (10 ppm sulfur maximum.)

The main concerns related to operation with biodiesel fuels are:

• United States: ASTM D975-10, Standard Specification for Diesel Fuel Oils. (15 ppm sulfur maximum.)

• Filters and injector blockage caused by poor fuel quality.

7-2

7 - MAINTENANCE

• 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 KOBELCO. Purchase biodiesel fuel from a trusted supplier who understands the product and maintains acceptable fuel quality.

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: KOBELCO 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 machine using the FPT NEF and Cursor 9 Common Rail Engines, no change to maintenance intervals is required when using biodiesel blends up to B7.
