Sudden Loss Of Engine Power - Komatsu 730E Operation & Maintenance Manual

Operation - Section 3
Page 3-12
Bring the truck to a safe stop as quickly as possible by using the foot pedal to apply the service brakes.
If possible, steer the truck to the side of the road while bringing it to a complete stop. Apply the parking brake as
soon as the truck has stopped moving. Turn key switch "Off" and notify maintenance personnel immediately.
If the truck becomes disabled where traffic is heavy, mark the truck with warning flags in daylight or flares at night.
If the engine suddenly stops, there is enough hydraulic pressure stored in the brake and steering accumulators to
allow the operation of the steering and brake functions. However, this oil supply is limited so it is important to stop
the truck as quickly and safely as possible after the loss of engine power. If the brake supply pressure drops to a
pre-determined level, the "Low Brake Pressure" warning light will illuminate and a buzzer will sound. If the brake
pressure continues to decrease, the "Auto-Apply" feature will activate and the service brakes will apply automati-
cally to stop the truck. Apply parking brake as soon as the truck comes to a complete stop.
SUDDEN LOSS OF POWER
