Engines Engine Starting Moving a vehicle with the starter and/or using the starter to bump the engine for maintenance proce- dures is strictly prohibited. Use of these methods to bump the engine over or move the vehicle can cause the pinion to release and re-engage, which could cause ring gear and starter pinion damage. NOTE: Before starting the engine, read Chapter 3 for detailed information on how to read the instru- ments and operate the controls. Whenever you start an engine, watch for any signs of engine problems. If the engine vibrates, misfires, or makes unusual noises, turn the engine off as soon as possible and determine the cause of the problem.
Fre- quently, engine damage may be avoided by a quick re- sponse to early indications of problems. IMPORTANT: Ring gear and starter pinion damage caused by improper starting procedures is not warrantable. Pre-Start CAUTION NOTE: These pre-start steps apply to all engines. 1. Perform the engine pretrip inspection and daily maintenance checks in Chapter 9 . When starting a vehicle equipped with a manual transmission and clutch lock out switch, the clutch pedal must be fully depressed during the entire start sequence. Failure to do so can cause the pin- ion to release and re-engage, which could cause ring gear and starter pinion damage. 2. Set the parking brake. 3.
For manual transmissions, place the transmission in neutral and disengage the clutch. If a vehicle does not start on the first attempt, make sure that the engine has completely stopped rotat- ing before reapplying the starter switch. Failure to do so can cause the pinion to release and re- engage, which could cause ring gear and starter pinion damage. For automatic transmissions, make sure the trans- mission shift control is in neutral or park. NOTE: On vehicles equipped with a neutral start switch, the transmission must be in neutral before the engine can be started. For air start systems, check the air supply before starting the engine.
There must be 100 psi (689 kPa) of air pressure available. 4.1
