V-MAC Co-Pilot Operator's Manual
STARTING THE VEHICLE The following procedure is used to start and warm up a vehicle management and control (V-MAC) IV engine during any ambient air temperature (AAT) condition: Note: Release the clutch and make sure the transmission is in neutral before starting the engine. 1 Turn the ignition key to the ON position clockwise. When the “Wait to Start” indicator on the instrument cluster shuts off, fully engage the starter. Release the ignition key as soon as the engine starts. Note: If the engine does not start immediately, limit cranking periods to 30 seconds to avoid overheating and damaging the starter. 2 After the engine has started, warm the engine until engine coolant temperature (ECT) reaches 60°C (140°F). After reaching 60°C (140°F), the engine can be operated normally. Note: If the engine does not start immediately, limit cranking periods to 30 seconds to avoid overheating and damaging the starter. Note: Warm-up time can be reduced by increasing engine idle speed between 1000–1200 RPM by either applying the throttle pedal or by using the variable speed governor (electronic hand throttle) feature. When operating unloaded, the engine may also be warmed by moving the vehicle (after one minute of idling time) with a “light” throttle application only. Note: Starter Protection will limit cranking time to avoid overheating the starter. If the starter has overheated, it will be forced off until it has cooled.
