Page 16: Engine Oil
Copyright © 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.
Page 17: Engine Fuel, Maintenance Of Fuel Filters And Fuel Storage
Copyright © 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.
Page 19: Anti-Freeze/Anti-Corrosion
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.
