General instructions If other equipment connected to the engine has altered its centre of gravity, special lifting devic- es may be needed to obtain the correct balance and safe handling. Only use the fuels recommended by Volvo Pen- ta. Please refer to the instruction book. The use of fuel of inferior quality can damage the engine. In a diesel engine, poor fuel can cause the regu- lation rod to bind and the engine will over-rev, en- tailing a strong risk of personal injury and ma- chinery damage. Poor fuel can also lead to high- er maintenance costs. Engine (24 V system voltage) Note.

Extra equipment Never do any work on an engine which just hangs from a lifting device. Cable colours BL = Blue P = Pink LBL = Light blue R = Red BN = Brown SB = Black LBN = Light brown VO = Violet GN = Green W = White GR = Grey Y = Yellow OR = Orange Never work alone when heavy components are to be dismantled, even when safe lifting devices such as lockable blocks & tackle are used. Even when lifting devices are used, two people are needed in most cases.

One who operates the lifting device and other who makes sure that components move freely and are not damaged during lifting. Remember the following when washing with a high pressure washer: Never aim the water jet at seals, rubber hoses, electrical components or the radiator. Never use the high pressure water for engine cleaning. Always make sure that there is enough space for disassembly where you are working, with no risk for personal or material damage. WARNING! Components in the electrical and fuel systems on Volvo Penta products have been designed to minimise the risks of explosion and fire. The engine must not be operated in en- vironments with adjacent explosive media.
