Pre-Start Inspection And Procedures
1. Make a "walk-around" inspection of the engine and components for the oil, water or fuel leaks and general appearance. Correct minor adjustments before they develop into major repair jobs.2. Check the crankcase oil level. Maintain the oil level between the ADD and FULL marks on the dipstick. See OIL SPECIFICATIONS for type of oil to use. 3. Check oil level(s) on driven equipment.
Check the engine coolant level when the engine is cool. If the engine is warm, steam may spray outward under high pressure and cause personal injury.
4. Check the engine jacket coolant level. Slowly turn the pressure cap until the cap is removed. Maintain coolant level to the base of the fill pipe. 5. Check the fuel supply. Keep fuel tanks full, as partially filled tanks will collect moisture. See the FUEL SPECIFICATIONS for type of fuel.Keep The Fuel Supply Clean
6. Open the raw water valve on the engine jacket heat exchanger system (if so equipped). Prime the raw water pump if the raw water system has been drained.7. Reset shutoff devices. See the topic, ATTACHMENTS, Emergency Shutoff Devices and Alarms.
OIL PRESSURE RESET
OVERSPEED RESETIf the engine is equipped with an air safety shutoff control, and was tripped to the shutoff position, reset the latch to the run position.
AIR SHUTOFF RESET8. Open the fuel supply valve. If the engine has not run for some time it may be necessary to prime the system. See the topic, PRIMING THE FUEL SYSTEM.9. Disconnect any battery charger which is not protected against starting motor drain.10. Disengage the clutch, or open the circuit breaker on a generator set.
