General Precautions
○ Proper service and repair procedures are important for the safety of the service mechanic and the safety
and reliability of the vehicle.
○ When 2 or more persons work together, pay attention to the safety of each other.
○ When it is necessary to run the engine indoors, make sure that exhaust gas is forced outdoors.
○ When working with toxic or flammable materials, make sure that the area you work in is well‐ventilated
and that you follow all of the material manufacturer's instructions.
○ Never use gasoline as a cleaning solvent.
○ To avoid getting burned, do not touch the engine, engine oil, radiator and exhaust system until they
have cooled.
○ After servicing the fuel, oil, water, exhaust or brake systems, check all lines and fittings related to the
system for leaks.
○ If parts replacement is necessary, replace the parts with genuine parts or their equivalents.
○ When removing parts that are to be reused, keep them arranged in an orderly manner so that they may
be reinstalled in the proper order and orientation.
○ Be sure to use special tools when instructed.
○ Make sure that all parts used in reassembly are clean. Lubricate them when specified.
○ Use the specified lubricant, bond, or sealant.
○ When removing the battery, disconnect the negative cable first and then the positive cable.
○ When reconnecting the battery, connect the positive cable first and then the negative cable, and replace
the terminal cover on the positive terminal.
○ When performing service to electrical parts, if the service procedures do not require use of battery
power, disconnect the negative cable from the battery.
○ When tightening the cylinder head or case bolts and nuts, tighten the larger sizes first. Always tighten
the bolts and nuts to the specified torque.
○ Whenever you remove oil seals, gaskets, packing, O‐rings, locking washers, self‐locking nuts, cotter
pins, circlips and certain other parts as specified, be sure to replace them with new ones. Also, before
installing these new parts, be sure to remove any left over material from the mating surfaces.
○ Never reuse a snap ring. When installing a new snap ring, take care not to expand the end gap larger
than required to slip the snap ring over the shaft. After installing a snap ring, always ensure that it is
completely seated in its groove and securely fitted.
○ Use a torque wrench to tighten fasteners to the specified torque. Wipe off grease and oil if a thread is
smeared with them.
○ After reassembling, check parts for tightness and proper operation.
○ To protect the environment, do not unlawfully dispose of used motor oil, engine coolant and other
fluids: batteries, and tires.
