❖
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 off the material manufacturer’s instructions.
❖
Never use gasoline as a cleaning solvent.
❖
To avoid getting burned, do not touch the engine, engine oil or exhaust system during or for a while
after engine operation.
❖
After servicing fuel, oil, 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 equivalent.
❖
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, and also lubricated when specified.
❖
When use of a certain type of lubricant, bond, or sealant is specified, be sure to use the specified type.
❖
When removing the battery, disconnect the negative cable first and then positive cable. When
reconnecting the battery, connect the positive cable first and then 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 bat- tery
power, diconnect the negative cable at the battery.
❖
Tighten cylinder head and case bolts and nuts, beginning with larger diameter and ending with smaller
diameter, from inside to outside diagonally, to the specified tightening torque.
❖
Whenever you remove oil seals, gaskets, packing, O-rings, locking washers, 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 leftover material from the mating surfaces.
❖
Never reuse a circlip. When installing a new circlip, take care not to expand the end gap larger than
required to slip the circlip over the shaft. After installing a circlip, always ensure that it is completely
seated in its groove and securely fitted.
❖
Do not use self-locking nuts a few times over.
❖
Use a torque wrench to tighten fasteners to the torque values when specified. Wipe off grease or oil if a
thread is smeared with them.
❖
After reassembly, check parts for tightness and operation.
