1. Drain the oil while the engine is still warm to assure rapid and complete draining.
2. Remove the drain plug and filler cap, and drain the oil. Retighten the plug securely.
3. Refill with the recommended oil and check the level.

⚠ Keep the generator level to prevent fuel spillage when transporting. Fuel vapor or spilled fuel may ignite.

1. With the fuel valve OFF, remove and empty the filter cup.
2. Turn the fuel valve ON and drain the gasoline in the fuel tank into a suitable container.
3. Replace the filter cup and tighten securely.
4. Drain the carburetor by loosening the drain screw; drain the gasoline into a suitable container.
5. Pull the starter grip until resistance is felt (piston on its compression stroke) to close the exhaust and intake valves.

⚠ After installing the filter cup, check for fuel leaks and make sure the area is dry before starting the engine.

1. Turn the fuel valve OFF. Remove the filter cup.
2. Clean the cup thoroughly.
3. Reassemble. Do not damage the rubber gasket.

⚠ Do not smoke or allow flames or sparks where the generator is refueled or where gasoline is stored.

1. Check the engine oil level with the generator on a level surface and the engine stopped.
2. Remove the oil filler cap and check the oil level; fill to the top of the oil filler neck with recommended oil if low.
3. Check the fuel level; use automotive gasoline with a research octane of 91 or higher or a pump octane of 86 or higher.
4. Make sure the AC circuit breakers are OFF.
5. Make sure the fuel tank cap is securely closed after refueling.

⚠ If the generator has been running, the muffler will be very hot. Allow it to cool before proceeding.

Tools: 8 mm bolts wrench

2. Clean any dirt from around the spark plug base.
3. Remove the spark plug cap.
4. Use the wrench supplied in the tool kit to remove the spark plug.
5. Visually inspect the spark plug; discard it if the insulator is cracked or chipped.
6. Measure the plug gap with a feeler gauge; the gap should be 0.6-0.7 mm. Correct by bending the side electrode.
7. Thread the plug in by hand to prevent cross-threading.
8. Tighten a new spark plug 1/2 turn with the wrench to compress the washer; if reusing a plug, 1/8-1/4 turn after it seats.
