1. PRECAUTIONS Precautions for Fuel DIESEL ENGINE Diesel fuel of at least 50 cetane for ZD30DDTi engine If two types of diesel fuel are available use summer or winter fuel properly according to the following temperature conditions e Above 7 C 20 F Summer type diesel fuel e Below 7 20 F Winter type diesel fuel CAUTION e Do not use home heating oil gasoline or other alternate fuels in your diesel engine The use of those can cause engine damage e Do not use summer fuel at temperature below 7 C 20 F The cold temperature will cause wax to form in the fuel As a result it may prevent the engine from running smoothly e Do not add gasoline or other alternate fuels to diesel fuel Precautions for Engine Oils Prolonged and repeated contact with mineral oil will result in the removal of natural fats from the skin leading to dryness irritation and dermatitis In addition used engine oil contains potentially harmful contaminants which may cause skin cancer Adequate means of skin protection and washing facilities must be provided HEALTH PROTECTION PRECAUTIONS 1 Avoid prolonged and repeated contact with oils particularly used engine oils 2 Wear protective clothing including impervious gloves where practicable Do not put oily rags in pockets Avoid contaminating clothes particularly underwear with oil Heavily soiled clothing and oil impregnated footwear should not be worn Overa2.
