EXPLANATION OF COMPONENTS OPERATION When starting the engine, G.O. (general operation) mode is auto- matically selected. Each time the switch is pressed, the mode selection changes. NOTICE When the breaker is used, never select the H.O. (heavy- duty operation) mode. REMARK H switch is also used for setting “hours” in the clock and M switch for setting “minutes”. see “DISPLAY” on page 64. 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. AD157780A 3. TRAVEL SPEED SWITCH 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. 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 AD157790A 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 lighted. NOTE: Switching from Hi to Mi or Lo can only be done when the machine is stationary and the service brake is applied (locked). If the Mi or Lo button is pressed without the service brake applied the indicator lamp will show selection of the desired mode but the machine will remain in Hi mode until such time as the service brake has been fully applied (locked). Switching from Mi to Lo or Hi or from Lo to Mi or Hi can be done at any time and whilst travelling.
