EXPLANATION OF COMPONENTS OPERATION SWING LOCK MONITOR This monitor (2) informs the operator that the swing lock is being actuated. Actuated: Lights up When the swing lock switch is turned ON (ACTUATED), the monitor lamp lights up. This monitor flashes when the swing holding brake cancel switch is turned on. REMARK The swing motor is equipped with a disc brake that mechani- cally stops the rotation. When the swing lock monitor lamp is lighted up, the brake remains applied. GAUGES AND METER ENGINE WATER TEMPERATURE GAUGE This monitor (3) displays the engine coolant temperature. During operations, the green range should be lighted up.
If the red range lights up during operations, the overheat prevention system is actuated. The overheat prevention system is actuated as follows. Red range (A) lights up:Engine water temperature monitor lamp (C) flashes. Red range (B) lights up:Engine speed is reduced to low idling, engine water temperature monitor lamp (C) flashes, and alarm buzzer sounds at the same time. The overheat prevention system is actuated until the gauge returns to the green range. When red range (A) has lighted up, wait for the engine water temperature to go down, then set the fuel control dial to low idling to cancel the display. FUEL GAUGE This meter(4) shows the fuel level in the fuel tank.
During nor- mal operation, the lamp should light up in the green range. If the lamp in the red range flashes during operation, there is less than 60 liters (15.85 US gal) of fuel remaining, so check and add fuel. Red range (A) lights up: Fuel gauge monitor lamp (B) flashes. The correct level may not be displayed for a short time after the starting switch is turned to the ON position, but this is not an abnormality. With the engine stopped, turn the starting switch ON to check that each item and meter lights up. 3-12
