CAUTION!

Do not store fuel from one season to another.

CAUTION!

Never place any type of storage cover on the generator 

while it is still hot.
When transporting or storing your generator for extended 

periods of time:

• Empty the fuel tank.

• Disconnect the spark plug.

• Do not obstruct any ventilation openings.

• Keep the generator in a cool dry area.

The cross-sectional of cable should not be less than that of 

below annex, and the length should not longer than 10m .

CHANGING/ ADDING OIL

NOTE:

You should check the oil level of your generator according to 

the maintenance schedule. When the oil level is low you will 

need to add oil until the level is sufficient to run the 

generator.
The oil capacity of your generator engine is 0.6L oz.

AIR CLEANER MAINTENANCE

Routine maintenance of the air cleaner helps maintain 

proper airflow to the carburetor. Occasionally check that the 

air cleaner is free of excessive dirt.

1. Unhinge the clasps at the top and bottom of the air

    cleaner cover (Fig.14, Fig. 15).

2. Remove the sponge-like elements from the casing.

3. Wipe the dirt from inside the empty air cleaner casing.

4. Wash the sponge-like elements in household detergent 

    and warm water. Allow to drying.

5. Soak the dry elements in engine oil. Squeeze out any 

    excess oil.

6. Replace the sponge-like elements in the air cleaner 

    casing and replace the cover.

FUEL FILTER CUP CLEANING

The fuel filter cup is a small well underneath the fuel valve. 

It helps to trap dirt and water that may be in your fuel tank 

before it can enter the engine. To clean the fuel filter cup:

1. Turn the fuel valve to the "OFF' position (Fig. 12).

2. Unscrew the fuel filter cup from the fuel valve using a 

    wrench. Turn the valve toward you to unscrew (Fig. 16).

3. Clean the cup of all sediment. Using a rag or brush.

4. Reinstall the fuel filter cup.

The spark plug is important for proper engine operation. A 

good spark plug should be intact, free of deposits, and

properly gapped. To inspect you spark plug:
1. Pull on the spark plug cap to remove it.

2. Unscrew the spark plug from the generator using the 

    spark plug wrench included with this product (Fig. 17).

3. Visually inspect the spark plug. If it is cracked or chipped, 

    discard and replace with a new spark plug.

4. Measure the plug gap with a gauge (Fig. 18). The gap 

    should be 0.7-0.8mm (0.028

-

0.031 in).

5. If you are re-using the spark plug, use a wire brush to 

    clean any dirt from around the spark plug base and then 

    re-gap the spark plug.

6. Screw the spark plug back into its place on the generator 

    using the spark plug wrench.

7. Replace the spark plug cap.

Before storing your generator for extended periods of time, 

you should drain your generator of petrol. To drain the 

generator of fuel:
1. Turn the fuel valve to the "OFF" position.

2. Remove the fuel filter cup.

3. Empty the fuel filter cup of any fuel.

4. With a receptacle underneath the generator to catch the

    fuel, turn the fuel valve to the "ON" position. Drain all the 

    fuel from the generator.

5. Turn the fuel valve to the "OFF" position.

6. Replace the fuel filter cup.

7. Store the emptied petrol in a suitable place.

It is only necessary to drain the oil from the crankcase if it 

has become contaminated with water or dirt. In this case, 

you can drain the oil from the generator according to the 

following steps:
1. Place a bucket underneath the generator to catch oil as it 

    drains.

2. Using a hex wrench, unscrew the oil drain plug, which is 

    located on the crankcase underneath the oil filler/dipstick 

    cap (Fig. 13). Allow all the oil to drain from the generator.

3. Replace the oil drain plug and tighten with a hex wrench.
To add oil to the crankcase, follow these steps:
1. Make sure the generator is on a level surface.

2. Unscrew the oil filler/dipstick cap from the engine (Fig. 1).

3. Using a funnel, add high detergent motor oil to the 

    crankcase. We recommend SAE 10W30 motor oil for 

    general use. When full, the oil level should come close in 

    the top of the oil fill opening (Fig. 2).

Never dispose of used motor oil in the trash or down 

a drain. Please call your local recycling center or 

auto garage to arrange oil disposal.

4. Insert the dipstick as if you were replacing the cap and 

    then remove again. There should now be oil on the stick. 

    If there is no oil on the stick, or oil only at the very end of

    the stick, you should add oil until the engine crankcase is 

    filled. 

5. Be sure to replace cap when finished checking oil.
