These precautions are not described in each individ- ual section. 4. Do not operate the engine for an extended period of time without proper exhaust ventilation. Keep the work area well ventilated and free of any inflam- mable materials. Special care should be taken when han- dling any inflammable or poisonous materials, such as gasoline, refrigerant gas, etc. When working in a pit or other enclosed area, be sure to properly ventilate the area before working with hazardous materials. Do not smoke while working on the vehicle. 2. Before jacking up the vehicle, apply wheel chocks or other tire blocks to the wheels to prevent the vehicle from moving. After jacking up the vehicle, support the vehicle weight with safety stands at the points designated for proper lifting and towing before working on the vehicle. ‘These operations should be done on a level surface. 3. When removing a heavy component such as the engine or transaxle/transmission, be careful not to lose your balance and drop them, Also, do not allow them to strike adjacent parts, especially the brake tubes and master cylinder. Before starting repairs which do not require battery power, always turn off the ignition switch, then disconnect the ground cable from the battery to prevent accidental short circuit. To prevent serious burns, avoid contact with hot metal parts such as the radiator, exhaust manifold, tail pipe and mut- fler. Do not remove the radiator cap when the engine is hot. GI-2Fender cover PRECAUTIONS 6. Before servicing the vehicle, protect fenders, upholstery and carpeting with appropriate covers Take care that keys, buckles or buttons on your person do not scratch the paint. 7. Clean all disassembled parts in the designated liquid or solvent prior to inspection or assembly. 8. Replace oil seals, gaskets, packings, O-rings, locking washers, cotter pins, self-locking nuts, etc. with new ones. 8. Replace inner and outer races of tapered roller bearings and needle bearings as a set. 10. Arrange the disassembled parts in accordance with their assembled locations and sequence. 11. Do not touch the terminals of electrical components which use microcomputers (such as electronic control units. Static electricity may damage internal electronic components. 42. After disconnecting vacuum or air hoses, attach a tag to indicate the proper connection. 48. Use only the lubricants specified in MA section. 14. Use approved bonding agent, sealants or their equivalents when required. 415. Use tools and recommended special tools where specified for safe and efficient service repairs. 46. When repairing the fuel, oil, water, vacuum or exhaust systems, check all affected lines for leaks. 17. Dispose of drained oil or the solvent used for cleaning parts in an appropriate manner. Precautions for E.F.I. or E.C.C.S. Engine 1. Before connecting or disconnecting E.F.l. or E.C.C.S. har- ness connector to or from any E.F.I. or E.C.C.S. control unit, be sure to turn the ignition switch to the "OFF" position and disconnect the negative battery terminal. Otherwise, there may be damage to contro! unit. 2. Before disconnecting pressurized fuel line from fuel pump to injectors, be sure to release fuel pressure to eliminate danger. 3. Be careful not to jar components such as control unit and air flow meter. GI-3PRECAUTIONS Precautions for Catalyst If a large amount of unburned fuel flows into the converter, the converter temperature will be excessively high. To prevent this, follow the procedure below: 1. Use unleaded gasoline only. Leaded gasoline will seriously damage the catalytic converter. 2. When checking for ignition spark or measuring engine compression, make tests quickly and only when necessary. 3. Do not run engine when the fuel tank level is low, otherwise the engine may misfire causing damage to the converter. 4. Do not place the vehicle on inflammable material. Keep inflammable material off the exhaust pipe. Precautions for Fuel Use unleaded gasoline with an octane rating of at least 87 AKI (Anti-Knock Index) number (research octane number 91).
