General Precautions (Cont’d) After disconnecting vacuum or air hoses, attach a tag to indicate the proper connection. • Use only the fluids and the lubricants specified in MA sec- tion and HA section or their equivalents • Use approved bonding agent, sealants or their equivalents when required • Use tools and recommended special tools where specified for safe and efficient service repairs. • When repairing the fuel, oil, water, vacuum or exhaust systems, check all affected lines for leaks. • Dispose of drained oil or the solvent used for cleaning parts in an appropriate manner. • Precautions for Multiport Fuel Injection System or ECCS Engine Sefore connecting or disconnecting multiport fuel injection system or ECM (ECCS control module) harness connector, be sure to turn the ignition switch to the “OFF” position and disconnect the negative battery terminal Otherwise, there may be damage to ECM. • Before disconnecting pressurized fuel line from fuel pump to injectors, be sure to release fuel pressure to eliminate danger • Be careful not to jar components such as ECM and mass air flow sensor • Precautions for Three Way Catalyst If a large amount of unburned fuel flows into the converter, the converter temperature wfll be excessively high. To prevent this, follow the procedure below: 1. Use unleaded gasoline only. Leaded gasoline will seri- ously damage the three way catalyst. 2. When checking for ignition spark or measuring engine compression, make tests quickly and onfy when neces- sary. 3. Do not run engine when the fuel tank level is low, other- wise the engine may misfire causing damage lo Ihe con- verter. Do not place the vehicle on flammable material. Keep flamma- ble material off the exhaust pipe and the three way catalyst Precautions for Turbocharger The turbocharger turbine revolves at extremely high speeds and becomes very hot. Therefore, it is essential to maintain a clean supply of oil flowing through the turbocharger and to follow all required maintenance instructions and operating procedures. For proper operation of Ihe system, follow the procedure below. 1 Always use the recommended oil. Follow the instructions for proper time to change the oil and proper oil level 2. Avoid accelerating engine to a high rpm immediately after starting. 3. If engine had been operating at high rpm for an extended period of time, let it idle for a few minutes prior [o shutting it off. Engine Oils Prolonged and repealed contact with used engine oil may cause skin cancer. Try to avoid direct skin contact with used oil. If skin contact is made, wash thoroughly with soap or hand cleaner as soon as possible HEALTH PROTECTION PRECAUTIONS • Avoid prolonged and repeated contact with oils, particu- larly used engine oils, • Wear protective clothing, including impervious gloves where practicable. • Do not put oily rags in pockets • Avoid contaminating clothes, particularly underpants, with oil. • Heavily sailed clothing and oil-impregnated footwear should not be worn. Overalls must be cleaned regularly • First Aid treatment shouid be obtained immediately for open cuts and wounds • Use barrier creams, applying them before each work period, to help the removal of oil from the skin • Wash with soap and water to ensure all oil is removed (skin cleansers and nail brushes will help). Preparations containing lanolin replace the natural skin oils which have been removed • Do not use gasoline, kerosine, diesel fuel, gas oil, Ihinners or solvents for cleaning skin • If skin disorders develop, obtain medical advice without delay • Where practicable, degrease components prior to han- dling • Where there is a risk of eye contact, eye protection should be worn, for example, chemical goggles or face shields; in addition an eye wash facility should be provided. i-v ENVIRONMENTAL PROTECTION PRECAUTIONS Burning used engine oil in small space heaters or boilers can . be recommended only for units of approved design The heat- ing system must meet the requirements of HM Inspectorate ol Pollution for small burners of less than 0,4 MW. If in doubt check with Ihe appropriate local authority and/or manufacturer of the approved appliance. Dispose of used oil and used oil fillers through authorized . waste disposal contractors to licensed waste disposal sites, or to the waste oil reclamation trade. If in doubt, contact the local authority for advice on disposal facilities, :•• It is illegal to pour used oil on to the ground, down sewers or drains, or into water courses The regulations concerning the pollution of the environment witl vary from country to country.
