1002-2 TABLE OF CONTENTS WARNING: This symbol is used in this manual to indicate important safety messages. Whenever you see this symbol, carefully read the message which follows. Your safety depends on it. TYPE, SERIAL NUMBER AND YEAR OF MANUFACTURE OF THE MACHINE..................... 5 Machine ..................................
For all part orders, request for information or assistance, always specify the type and the serial number of the machine to your Case dealer. Fill in the following lines with the required information: Type, serial number, year of manufacture of the machine and the serial numbers of the hydraulic and mechanical components.
CASE/AKCELA: HYDRAULIC EXCAVATOR FLUID (MS 1230. ISO VG 46. DIN 51524 PART 2 HV) Hot climates: 0°C to +50°C (32° to 122° F) CASE/AKCELA: AW HYDRAULIC FLUID 68 HV (MS 1216. ISO VG 68. DIN 51524 PART 3 CATEGORY HVLP) Cold climates: -25°C to +20°C (-13° to 68° F) CASE/AKCELA: AW HYDRAULIC FLUID 32 (MS 1216.
1002-7 Engine Oil THE CASE/AKCELA No. 1 engine oil is recommended for your engine. This oil ensures proper lubrication of your engine for all operating conditions. If the CASE/AKCELA Multigrade "No. 1 ENGINE OIL" cannot be obtained, use the oil corresponding to one of the following categories: ACEA E7 API CI-4.
1002-8 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.
Page 18
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.
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.
