When pushed inward and held, this switch has several uses. 1. The override switch permits the operator to move the truck forward when the selector switch is in FORWARD, the dump body is raised, and the brakes are released. Only use the override switch in emergency situa- tions. 2. If the operator stops the truck on an uphill incline, the override switch can be used to set up the forward propulsion while the brakes are applied. As soon as the forward propulsion is felt, release the brakes. As the truck begins to move forward, release the override switch. 3. The override switch deactivates the retard pedal function when the speed of the truck is below 5 kph (3 mph). 4.
The override switch is also used to reset an elec- tric system fault when indicated by the red warn- ing light. Refer to Overhead Warning/Status Indicator Light Panel in this section.
