CHECKS DURING OPERATION While running, make the following checks to see that all parts are working correctly. Radiator Cooling water (Coolant) To avoid personal injury: • 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. When the engine overheats and hot coolant overflows through the overflow pipe and cannot be stopped, stop the engine immediately and make the following checks to determine the cause of trouble: 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. Check to see if there is any dirt or dust between radiator fins and tube; 4. Check to see if the fan belt is too loose; 5. Check to see if radiator water pipe is clogged; and 6. Check to see if anti-freeze is mixed into coolant in warm seasons. Fuel To avoid personal injury: • Fluid escaping from pinholes may be invisible. Do not use hands to search for suspected leaks; Use a piece of cardboard or wood, instead, If injured by escaping fluid, see a medical doctor at once. This fluid can produce gangrene or a severe allergic reaction. • Check any leaks from fuel pipes or fuel injection pipes. Use eye protection when checking for leaks. Be careful not to empty the fuel tank. Otherwise air may enter the fuel system, requiring fuel system bleeding. While the engine is run within the rated output range: • The color of exhaust remains colorless. • If the output slightly exceeds the rated level, exhaust may become a little colored with the output level kept constant. • If the engine is run continuously with dark exhaust emission, it may lead to trouble with the engine. • Immediately stop the engine if; • The engine suddenly slow down or accelerates. • Unusual noises suddenly appear. • Exhaust fumes suddenly become very dark. 8.2. MAINTENANCE SCHEDULE Perform maintenance at whichever interval that occurs first. At each scheduled maintenance interval, perform all previous maintenance checks that are due for scheduled mainAR- EXP-CUMMINS-07-00 OWNERS MANUAL Page 29 tenance.

NOTE: The lubricating oil and lubricating oil filter interval can be adjusted based on application, fuel consumption, gross vehicle weight, and idle time. For engines whose aspiration is jacket water- cooled, turbocharged only, or natural, refer to Table in the Oil Drain Intervals section. 2. The lubricating oil and lubricating oil filter interval can be adjusted based on application, fuel consumption, gross vehicle weight, and idle time. For engines whose aspiration is charge air cooled, refer to Table in the Oil Drain Intervals section. 3. Antifreeze check interval is every oil change or 500 hours or 6 months, whichever occurs first. The operator must use a heavy-duty year-round antifreeze that meets the chemical composition of GM6038M. The antifreeze change interval is 2 years, 2000 hours, or whichever occurs first. Antifreeze is essential for freeze, overheat, and corrosion protection. 4. Follow the manufacturer's recommended maintenance procedures for the starter, alternator, generator, batteries, electrical components, charge air cooler, radiator, air compressor, air cleaner, refrigerant compressor, and fan clutch.
