Lubrication Oil
Fill the engine crankcase with lubricating oil through the filler hole, but do not overfill. Make sure the generator is level. With the dipstick inserted all the way, but without being screw into the filler hole, verify that the oil level is maintained between the two notches (Figure 28) on the dipstick. See Table 9 for proper selection of engine oil.
Fuel
Fill the fuel tank with clean and fresh diesel fuel. DO NOT fill the tank beyond capacity.
Pay attention to the fuel tank capacity when replenishing fuel. Refer to the fuel tank capacity listed on page 23, Specification Table 7.
The fuel tank cap must be closed tightly after filling. Handle fuel in a safety container. If the container does not have a spout, use a funnel. Wipe up any spilled fuel immediately.
Figure 28. Engine Oil Dipstick
When checking the engine oil, be sure to check if the oil is clean and viscous. If the oil is not clean, drain the oil by removing the oil drain plug, and refill with the specified amount of oil as outlined in the Komatsu Engine Owner's Manual.
CAUTION:
Never fill the fuel tank while the engine is running or in the dark. Diesel spillage on a hot engine can cause a fire or explosion. If diesel spillage occurs, wipe up the spilled diesel completely to prevent fire hazards.
Coolant
Use only drinkable tap water. If hard water or water with many impurities is used, the inside of the engine and radiator may become coated with deposits and cooling efficiency will be reduced.
An anticorrosion additive added to the water will help prevent deposits and corrosion in the cooling system. See the engine manual for further details.
