Chapter 3 OPERATION
Preparations for operation
Always conduct the following inspection before starting the engine.
Engine external - Inspect
Inspect the engine exterior as described below.
1. Make sure there is no combustible material near the engine or battery. Also, check to make sure that the engine
and battery are clean. If combustible materials or dust are found near the engine or battery, remove them.
2. Check the electrical wiring for such components as the starter and alternator for looseness.
3. Check the entire engine for fuel leakage, engine oil or coolant. If leakages are found, repair or contact a dealer
of Mitsubishi Heavy Industries, Ltd.
4. Make sure the following valves, plugs and cocks are open or closed (tightened) properly:
Fuel feed valve: Open
Coolant drain cock (plug): Closed (Tightened)
Oil drain valve: Closed
Battery electrolyte level - Inspect
Battery electrolyte evaporates during use and the
electrolyte level gradually decreases. Proper electro-
lyte surface level is between the "LOWER LEVEL"
and "UPPER LEVEL" lines.
For the battery without level lines, proper electrolyte
surface level is about 10 to 15 mm [0.394 to 0.591 in.]
above the top of the plates.
If the electrolyte level is low, remove the caps and add
distilled water to the proper level.
Note: When adding distilled water, pour in carefully.
Fig. 3-1 Battery electrolyte level - Inspect
Should an engine abnormality be observed during operation, stop the engine and correct the problem, or contact a
dealer of Mitsubishi Heavy Industries, Ltd.
Be sure to keep combustible materials away from the engine, especially from the hot engine parts such as exhaust
manifolds, or the battery. Check for fuel and oil leakage. Clean the top surface of the battery. A fire can be caused
by combustible materials placed near hot engine parts. If any abnormality is found, be sure to repair it or contact a
dealer of Mitsubishi Heavy Industries, Ltd.
If battery electrolyte is spilled on your skin or clothes, flush immediately with plenty of water. If battery electrolyte
get into your eyes, flush them immediately with plenty of water and then get medical attention.
Do not use open flames or other fire hazards near the battery. When handling the battery, be careful of sparks gen-
erated by accidental shorting. For other cautions in handling the battery, refer to "Service battery" (1-6).
