SPARK ARRESTOR MAINTENANCE

It is recommended to inspect and clean the spark arrestor (Fig. 23 - 1) every

100 hours of operation.

1. The spark arrestor is located outside the mufﬂer, which gets very hot dur-

ing operation. Allow the engine to cool completely before servicing the spark

arrestor.

2. Unscrew the six Phillips head screws and remove the mufﬂer cover.

3. Remove the screw that holds the spark arrestor (Fig. 23 - 1) to the mufﬂer.

4. Remove the spark arrestor screen.

5. Carefully clean and remove the carbon deposits from the spark arrestor screen with a wire brush. Replace the

spark arrestor if it is damaged (part no. 56477i-115, available for purchase at wenproducts.com).

6. Reinstall the spark arrestor in the mufﬂer and secure it in place with the screw.

7. Replace the mufﬂer cover and secure it with the six screws.

DRAINING THE FUEL TANK

1. Prepare an approved gasoline-storage container. Make sure the engine switch is turned to OFF.

2. Open the right side panel to access the carburetor, as instructed on the previous page.

3. Open the carburetor drain screw and turn the 4-in-1 switch to “RUN”. This will allow gasoline to drain from the

gas tank through the carburetor.

NOTE: It may take a few hours for your tank to drain completely, depending on the amount of gasoline in the tank.

4. Once drained fully, close the carburetor drain screw, turn the engine switch OFF, and close the side panel.

CAUTION! Running the engine with a dirty, damaged, or missing air ﬁlter will result in possible danger and

cause the engine to wear out prematurely.

BATTERY MAINTENANCE & STORAGE

The lithium-ion battery will receive charge when the engine is running. Remember to run the generator once a

month for 20-30 minutes to charge the battery. A charged battery will allow you to start the generator using the

electric start button during your next time of need. If the battery is out of charge, you may start the generator using

the recoil starter. If the generator is not used for a long period, it is recommended to disconnect the quick-connector

to protect it from losing charge. TIP: You can also connect the battery to an automatic trickle charger to keep the

battery charged. If using a trickle-charger, charge the battery at room temperature.

Lithium-ion batteries can be damaged or suffer a shortened lifespan if they are charged in very cold temperatures

(below freezing). If you expect to store the generator in temperatures below 25°F (-5°C), we recommend removing

the battery from the generator and storing it indoors. If using the generator in temperatures below 25°F (-5°C), we

recommend running the generator for at least 15 minutes with the battery removed, or the quick-connector discon-

nected and covered with an insulator such as electrical tape, and then connecting the battery. This will allow the

inside of the generator to warm up, and will greatly reduce the chance of damage to the battery.

WARNING! It is best to store the battery indoors at room temperature. Do not store your battery outside in

the winter, where temperatures may go below 25°F (-5°C), or in any location where temperatures may exceed

104°F (40°C), such as in direct sunlight or inside a vehicle or metal building during the summer.
