24. SERVICE PROCEDURE 24.7.4 CLEAN AND INSPECT RADIATOR FINS, OIL COOLER FINS AND CONDENSER FINS (ONLY FOR MACHINES EQUIPPED WITH AIR CONDI- TIONER) WARNING If compressed air, steam, or water hit your body directly, there is danger of injury. Always wear protective glasses, mask and safety shoes. 1. Open the engine hood and the battery room door on the left side of the machine. 2. When cleaning radiator fins, remove four bolts , fixing the oil cooler to the radiator. Tilt the oil cooler outward, then clean the radiator fins. 3. Blow off mud, dust or leaves clogging the radiator fins and oil cooler fins using compressed air. At the same time, clean the net in front of the oil cooler.
Clean the condenser fins on machines equipped with the air condi- tioner. Steam or water may be used instead of compressed air. 4. After cleaning, fix the oil cooler with bolts . 5. Check the rubber hose. Replace with a new one if the hose is found to have cracks or to be hardened by ageing. Further, check hose clamps for looseness. NOTICE To prevent damage to the fins, apply compressed air from an appropriate distance. Damaged fins may cause water leakage or overheating. In a dusty site, check the fins daily, irrespective of the maintenance interval. PC130/150LGP-6K ENG 3-57
