d. CHECK FUEL LEVEL 1. Check the fuel level using sight gauge (G) on the side face of the tank. 2. Upon completion of work, pour in additional fuel through filler (F) until the fuel tank is full. * When adding fuel, never let the fuel overflow. This may cause a fire. * If breather hole (1) in the cap is blocked up, fuel flow to the engine may stop. Accordingly, clean it from time to time. t Fuel capacity: 510 II e. CHECK OIL LEVEL IN HYDRAULIC TANK 1. Run the engine at low speed, retract the arm and bucket cylinders, then lower the boom, set the bucket teeth in contact with the ground, and stop the engine. 2.
Operate all the control levers (work equipment and travel) in all directions to the end of their stroke to release the internal pressure. * Carry out this operation within 15 seconds of stopping the engine. 3. If the level of hydraulic oil is not between top H and bottom L lines of sight gauge (G), pour in additional engine oil through filler (F). * The type of lubricant used depends on the ambient temperature. Select according to the table “FUEL, COOLANT AND LUBRICANTS”. t Do not pour in additional oil if the level is above the top line H of the sight gauge. * The oil level will vary depending upon the oil temperature. Accordingly, use the following as a guide:
0 When the oil temperature is close to the ambient temperature (10 to 30X), the level will be close to bottom line L on the sight gauge. 0 When the oil temperature is the normal operating temperature (50 to 80X), the level will be close to top line H on the sight gauge. - 52 -
