CHECK BEFORE STARTING Pre-operation checks forestall machine trouble. Never neglect them. a. WALK-AROUND CHECK Look around the machine and under the machine to check for loose nut or bolts, collection of dirt, or leakage of oil, fuel, or coolant, and check the condition of the work equiment and hydraulic system. Check also for loose wiring, play, and collection of dust at places which reach high temperatures. 1. Check for oil leak at high pressure hose, high pressure hose joints and hydraulic cylinder seal. 2. Check tightness of idler mounting bolt. 3. Check tightness of battery terminal. 4. Check radiator for water leaks. 5. Check around the engine for water and oil leaks. 6.
Check final drive case for oil leaks and check tightness of sprocket mounting bolt. 7. Check tightness of air cleaner mounting bolt. b. CHECK AND REFILL COOLANT Open the cover at the rear of the machine and check that the cooling water is inside the correct range (shown in the diagram on the right) for sub-tank (1). If the water level is low, add water through water filler (2). (3): FULL (4): LOW * If the volume of coolant added is more than usual, check for possible water leakage. A Do not remove the cap while cooling water is hot. Hot water may spout out.
When removing the cap, wait until the water temperature goes down and release radiator pressure little by little by loosening the cap slowly, then remove the cap. C. 1. 2. 3. CHECK OIL LEVEL IN ENGINE OIL PAN Open the cover at the rear of the machine. Use the dipstick (G) to check the oil level. The oil level should be between mark L and H, if necessary, add oil at the oil filler (F). The type of lubricant used depends on the ambient temperature. Select according to the table “FUEL, COOLANT AND LUBRICANTS”. When checking the oil level, park the machine on a level surface, stop the engine and wait for 15 minutes before checking. * * - 50 -
