11. EXPLANATION OF COMPONENTS 2. AUTO-DECELERATION SWITCH (Selection switch) This switch acts to activate the function that automatically lowers the engine speed and reduces fuel consumption when the control lever is at neutral. ON lights up: Auto-deceleration is actuated. OFF: Auto-deceleration is cancelled. Each time the switch is pressed, the auto-deceleration is actuated or cancelled. 3. TRAVEL SPEED SWITCH This is used to select the three travel speeds. Lo lights up: Low speed travel Mi lights up: Mid range speed travel Hi lights up: High speed travel When the engine is started, the travel speed is automatically set to Lo.
When travelling in Hi, the travel speed is automatically adjusted to match the travel surface on soft ground or when travelling uphill, so there is no need to operate this switch. The monitor indication keeps lamp Hi or Mi lighted. PC450-ENG 2-13 WARNING If the Hi-Lo switch is operated when the machine is travelling, the machine may deviate even when travelling in a straight line. To prevent this, always stop the machine before operating the travel speed switch. WARNING
