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 13) on the dipstick. See Table 7 for proper selection of engine oil.
Figure 13. 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 Kubota Engine Owner's Manual.
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 19 Specification Table 5.
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.
CAUTION :
Never fill the fuel tank while the engine is running or in the dark. Gasoline spillage on a hot engine can cause a fire or explosion. If gasoline spillage occurs, wipe up the spilled gasoline 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. See maintenance section on page XX and XX on instructions to flush out radiator.
An anticorrosion additive added to the water will help prevent deposits and corrosion in the cooling system.
