1 General 1-9 Warnings and Notices Important precautions for exhaust manifold and oxygen sensor CAUTION: - When the engine temperature is higher than 48 ℃ , the oxygen sensor will be difficult to remove, while excessive force will damage the exhaust manifold or exhaust pipe thread. Important precautions for exhaust system inspection CAUTION: - When inspecting or replacing the exhaust system components, ensure that there is sufficient clearance from all points under the body to avoid overheating of the floor and possible damage to passenger compartment mats and trim materials. Important precautions for torque reaction against timing drive chain CAUTION:
- To avoid component damage, use a wrench to pull the hexagon part of the camshaft during removal or installation. If the torque reaction against timing chain cannot be avoided, the timing chain will fail. Important precautions for removal of exterior markings CAUTION: - When removing signs/nameplates, use a plastic flat-edged tool to avoid damaging the paint. Important precautions for fasteners CAUTION:
- Please use the correct fasteners in the right place, replace the fasteners with correct part number, specify the fasteners needed to be replaced or use thread locking adhesive or sealant in maintenance procedures, and do not use the paint, lubricants or resistance corrosion inhibitors on the fastener or its connection part, unless otherwise specified. These coatings affect the torque and clamping force of fasteners and will damage them. When installing fasteners, use the correct tightening sequence and torque to avoid damaging the parts and system. Important precautions for fuel pressure CAUTION:
- The fuel pressure must not exceed the specified value, otherwise the fuel pressure regulator may be damaged. Precautions for handling electrostatic discharge sensitive components CAUTION: - Handle all electrical components with care because that electrostatic discharge (ESD) will damage many solid electrical components. Observe the following safety precautions to avoid ESD damage: ● Before maintaining any electrical component, touch the metal ground point to release static electricity from the body. ● Do not touch bare terminals. The terminals may be connected to circuits easily damaged by electrostatic discharge.
● When maintaining the connector, do not touch the bare terminal with the tool. ● Do not remove parts from protective housing unless otherwise specified. - Avoid the following operations unless it specifically stated in diagnostic procedures: ● Make the part or connector bonded or grounded. ● Connect the probe of the test equipment to the component or connector. When using the probe, connect the ground lead first. ● Ground the protective housing of the component before opening it. Do not place the solid component on top of a metal workbench or other electrical equipment. VOYAH FREE
