Note: High ambient temperature will cause nuisance tripping.
ENGINE OIL
We ship the generator without oil in the engine crankcase. You must add oil before starting engine. See engine owner’s manual for specific oil type.
CHECKING OIL LEVEL AND ADDING OIL
Follow steps below to check oil level. Make sure engine is level and stopped.
1.Remove dipstick (see Figure 7). Wipe dipstick clean.
2.Insert dipstick into oil filler neck. Do not screw it in. Oil level should be at top of filler neck. Oil should cover most of dipstick. For Model MGH10000A only, the oil should be between the two dots on dipstick.
3.If level is low, fill to top of oil filler neck (see Figure 7). For Model MGH10000A only, fill to top dot on dipstick. Only use oil recommended in engine owner’s manual.
Note: If oil level is too low, oil alert system will shutdown engine and prevent engine from restarting.

FUEL
WARNING: Gasoline presents a hazard of fire or explosion. Gasoline is flammable. Its vapor is explosive.
•Keep fuel out of children’s reach.
•Refuel generator in a well- vented area. Do not fill fuel tank in the dark. Do not refuel while engine is running. Unhook all electrical loads and shut off engine before refueling.
•Do not overfill fuel tank. Al- ways allow room for fuel to expand. If you overfill tank, fuel can overflow onto hot engine. This can cause fire or explo- sion. After refueling, tightly close fuel tank cap.
•Do not spill fuel. Fuel or fuel vapor may ignite. If fuel spills, make sure area is dry before starting engine.
•Never smoke in refueling area. Never allow open flames or sparks in area.
•Store fuel in approved con- tainer. Store fuel in a well- vented area free of open flames or sparks.
Use clean, fresh, unleaded gasoline. Use gasoline with octane rating of 86 or higher. Service station gasoline pumps should dis- play the octane rating. Using gasoline with lower octane level could damage engine. Avoid getting dirt, dust, or water in fuel tank. Do not mix oil with gasoline.
See engine owner’s manual for more information.
