Oil Capacity - Hitachi E10U Handbuch

English
NOTE: There is no oil in the engine crankcase when the generator is shipped. You must add oil before
starting the engine. Check the oil level before each use with the generator on a level surface and
the engine stopped.
Engine oil is a major factor affecting engine performance and service life. Non-
detergent and 2-stroke oils will damage the engine and are not recommended.
Use 4-stroke motor oil that meets or exceeds the requirements for API service
classification SE or better.
Always check the API SERVICE label on the oil container to be sure it includes
the letters SE or better. SAE 10W- 30 or 10W-40 is recommended for general,
all-temperature use. Other viscosities shown in Fig.23 may be used when the
average temperature in your area is within the indicated range.
CHECKING THE OIL
Remove the oil maintenance cover and oil filler cap and inspect if the engine oil
is at the upper level (standard level) on the oil level gauge.
If the level is low, supply new oil to the standard level.
NOTE: ● Tighten the oil filler cap securely.
● Be sure to wipe off spilled engine oil.
● Use API classification class SE or better SAE 5W or 5W-30 oil at cold

NOTE: If the oil level is too low, the oil alert system will shutdown the
engine and prevent engine from restarting.
FUEL
WARNING: Gasoline is flammable and its vapor is explosive. To prevent fire or explosion, follow the
• Keep fuel out of the reach of children.
• Refuel the generator in well-ventilated area. Do not refuel while engine is running or hot. Disconnect all
electrical loads and shut off the engine before refueling.
• Do not overfill the fuel tank. Always allow room for fuel vapors to expand. If you overfill the tank, fuel
can overflow onto the hot engine. This can cause fire or explosion. After refueling, tightly close the fuel
tank cap.
• Do not spill fuel. Fuel or fuel vapor may ignite. If fuel spills, make sure that the area is dry before
starting the engine.
• Never smoke in the refueling area. Never allow open flames or sparks in area.
• Store fuel in an approved container. Store fuel in a well ventilated area free of open flames or sparks.

Remove the fuel tank cap and inspect the fuel level. If the fuel evel is low, supply
fuel so that the filling limit position (red level) is not exceeded. Refuel carefully to
avoid spilling fuel.
Use unleaded gasoline with a pump octane rating of 86 or higher.
The engine is certified to operate on unleaded gasoline.
Unleaded gasoline produces fewer engine and spark plug deposits and extends
exhaust system life. Never use stale or contaminated gasoline. Avoid getting dirt
or water in the fuel tank.
Always keep the fuel strainer in place while refueling.
