Return the speed control lever to low idle, and run the engine under idling conditions. B Radiator cooling water(Coolant) 2. Set the engine stop lever to the "STOP" position. To avoid personal injury: A Do not remove radiator cap until coolant temperature is well below its boiling point. Then loosen cap slightly to the stop position, to relieve any pressure, before removing cap completely. 3. With the starter switch placed at the "OFF" position, remove the key.
(Be sure to return the engine stop lever to the "START" position to be ready for the next start.) If the water temperature warning lamp lights up or overflow of steam or water from the overflow pipe does not stop, stop loading and let the engine “COOL DOWN” by idling for at least 5 min. Allow the engine to cool down gradually, stop the engine and proceed to the next inspection and maintenance work according to “RADIATOR” section. Check item 1. Check to see if there is any coolant leak; 2. Check to see if there is any obstacle around the cooling air inlet or outlet; 3.
