Safety, general information and standard torque data ROPS Judgment Method 1.

2.

Purpose Check against the ROPS judgment criteria to judge whether the machine satisfies the ROPS criteria or not. The weight and boom of the machine greatly effects whether the ROPS judgment criteria is satisfied or not. The ROPS test assumes that the weight being used is the weight of the machine when the maximum number of selectable options are mounted (as of 2009). However, depending on the derivative machinery or the order details, the weight and boom position may differ from the assumed weight or position. Criteria for judging whether a machine satisfies the ROPS criteria 1)

Weight The weight must not be over the weight shown below for each class. If the weight is exceeded, there is a danger that the cab could be damaged and the operator could die or sustain a serious injury when the machine falls over. If the weight exceeds the stipulated weight, the machine will not satisfy the ROPS criteria. • Weight (C series model) To satisfy the ROPS criteria, the weight must not be over the indicated weight. (The below weights are the weights indicated on the nameplate within the ROPS cab) Machine weight

body

total

Class CX250C CX250CLR CX300C CX370C CX470C

31000 kg or less 40000 kg or less 50000 kg or less

* The ROPS test assumes that the CX470C has a cage guard (alone). • Weight (B series model) To satisfy the ROPS criteria, the weight must not be over the indicated weight. (The below weights are the weights indicated on the nameplate within the ROPS cab) Machine weight

body

25000 kg or less

Safety, general information and standard torque data 2)

Boom position WARNING • If the machine has been modified so that the boom position has been lowered, the machine will not satisfy the ROPS criteria. • It is necessary to consult with our company if it is possible that the boom's position has been lowered by modification. • The extent to which a boom position has moved cannot be determined in the same way for all machines.

a

Ground point

With the tip of the bucket in contact with the ground surface at maximum work radius, if the position (* in the diagram) that overlaps with the cab when viewed from the side is markedly lower than that of a standard machine (standard arm), the machine will not satisfy the ROPS criteria. Also, with a machine body with a cab mounted that can withstand up to 31 tons, the effect of mounting a 24 ton machine, which is near the restriction weight, and a 21 ton machine to the same cab will not be the same.

84402832 NA - May 2011 1001-7


Safety, general information and standard torque data 3.

Prohibited items • Modifications that reduce the strength of a platform that has a cab with a ROPS mounted to it. (Actions or modifications that reduce the functionality of the anchoring part at the left-rear of the cab) • Modifications that effect the strength of the ROPS of a cab. A forbidden all modifications (red part) Allow under specified conditions (gray part)

All modifications (grinding, welding, drilling holes, removing, etc.) are prohibited. Removal of parts is prohibited. Bar welding and making holes (up to diameter 20 mm) by drilling are possible.

FLUIDS AND LUBRICANTS Lubricants must have the correct properties for each application. IMPORTANT: The conditions of use for individual fluids and lubricants must be respected.

HYDRAULIC FLUID CASE/AKCELA hydraulic fluid is specially designed for high pressure applications and for the CASE hydraulic system. The type of fluid to be used depends on the ambient temperature.

ENGINE OIL The "CASE Tutela LE ENGINE OIL" is recommended for your engine. This oil ensures correct lubrication of your engine in all working conditions. If the "CASE Tutela LE ENGINE OIL" cannot be obtained, use the oil corresponding to one of the following categories: API CJ-4. ACEA E6.

FUEL The fuel must conform to Interim Tier 4/Stage 3B Exhaust Gas Control Regulations. Use grade number 2-D (S15) fuel. Using other types of fuel may lead to stalled engine output or deterioration in fuel economy. During cold weather (lower than -7℃), it is temporarily acceptable to use a mixture of No. 1-D (S15) and No. 2-D (S15). Consult the fuel supplier or the CASE dealer. If the temperature drops below the fuel cloud point, output deficiency or engine start problems may occur due to wax crystals.

Conditions applicable to diesel fuel The diesel fuel used must: -

be free from dust particles, even minute ones, have the proper viscosity, have a high cetane number, present great fluidity at low temperatures, have low sulphur content, have very little residual carbon.

RECOMMENDED CONDITIONS THAT CAN BE APPLIED TO DIESEL FUEL - JIS (Japanese Industrial Standards): No. 2 - DIN (Deutsche Industrie Normen): DIN 51601 - SAE-J-313C: SAE (Society of Automotive Engineers) based on No. 2-D (S15) - BS (British Standards) based on BS/2869-1970: Class A-1 - EN 590 (less than 10 ppm sulfur) - Or fuel specified by the country using these standards and this machine

IMPORTANT: EPA regulation ultra low sulfur fuel only. IMPORTANT: If a serious problem occurs when other fuels are used, the warranty is invalidated. Using a non-recommended fuel may lead to damage of the fuel injection pump, injector, DPD, and other fuel supply systems or to the engine. CASE assumes no responsibility for these damages. Note that the warranty will not be applied for these damages. It is recommended that the following safety information be considered in order to prevent damage to the engine fuel supply system. - Some fuel suppliers mix old engine oil and diesel fuel. Makers of larger engine permit the use of this kind of fuel. However, do not use diesel fuel contaminated with engine oil in customer's engines. Not only will this fuel damage the engine, it may also have a negative impact on the exhaust gas purification function. Before using diesel fuel, confirm with the supplier whether the fuel complies with the above specifications. IMPORTANT: Consult the supplier or the CASE dealer regarding appropriate use of fuel additives. Do not use fuel oil or gasoline as these may damage the engine. IMPORTANT: In order to prevent condensation during cold weather, fill the fuel tank to full after the completing the day's work.
