MAINTENANCE

BATTERY MAINTENANCE

The battery shipped with the generator has been fully 

charged. A battery may lose some charge when not in use 

for prolonged periods of time.  

Note: 

Once started, the generator will charge the battery 

after 30–60 minutes of use.  

The included trickle charger can remain connected and will 

maintain the battery for an indefinite period of time. A red 

light on the charger indicates charging in progress. A green 

light indicates charging complete. Charge in a dry location. 

1. 

Plug the charger into the battery charging port on the 

control panel. 

2. 

Plug the wall receptacle end of the battery charger into 

a 120 Volt AC wall outlet.

BATTERY REPLACEMENT

Burn hazard. The battery contains sulfuric acid 

(electrolyte) which is highly corrosive and poisonous. 

Wear protective clothing and eye protection when 

working near the battery. Keep children away from the 

battery. 

Battery posts, terminals contain lead and lead 

compounds. Wash hands after handling. 

1. 

Loosen and remove the bolt on the battery hold-down 

plate and swing the plate out. 

2. 

Disconnect the quick-connect plugs and remove the 

battery from the unit. 

3. 

Disconnect the quick-disconnect cable leads from the 

battery. 

4. 

On the replacement battery, connect the white (-) quick-

connect cable to the battery negative terminal. Slide the 

rubber boot over the connection hardware. 

5. 

Connect the red (+) quick-connect cable to the battery 

positive terminal. Slide the rubber boot over the 

connection hardware. 

6. 

Install the battery into the generator. Reinstall the battery 

hold-down plate and tighten the bolt. 

7. 

Connect the quick-connect plug. 

NOTICE

Dispose of the used battery properly according to the 

guidelines established by your local or state government.

STORAGE

Proper storage preparation is required for trouble-free 

operation and generator longevity.  

NOTICE

Gasoline stored for as little as 30 days can deteriorate, 

causing gum, varnish, and corrosive buildup in fuel lines, 

fuel passages, and the engine. This corrosive buildup 

restricts the flow of fuel, which can prevent the engine 

from starting after a prolonged storage period. The use 

of fuel stabilizer significantly increases the storage life of 

gasoline. Full-time use of fuel stabilizer is recommended. 

Follow the manufacturer’s instructions for use. 

STORAGE TIME

RECOMMENDED PROCEDURE

Less than 1 month

No service required.

2 to 6 months

Fill with fresh gasoline and add 

gasoline stabilizer. Drain the 

carburetor float bowl.

6 months or longer

Drain the fuel tank and carburetor 

float bowl. 

SHORT TERM STORAGE

•  Allow the generator to cool a minimum of 30 minutes 

before storage.  

•  Replace all protective covers on the generator control 

panel. 

•  Wipe the generator with a moist cloth. Clean any debris 

from the muffler cooling vents.   

•  Store the generator in a well-ventilated, dry location 

away from sparks, open flames, pilot lights, heat, and 

other sources of ignition such as areas with a spark-

producing electric motor or where power tools are 

operated. 

•  Do not store the generator or gasoline near furnaces, 

water heaters, or any other appliances that produce 

heat or have automatic ignitions.

•  With the engine and exhaust system cool and all 

surfaces dry, cover the generator to keep out dust. Do 

not use a plastic sheet as a dust cover. Non-porous 

materials trap moisture and promote rust and corrosion.
