SPARK ARRESTOR MAINTENANCE

It is recommended to inspect and clean the spark arrestor (Fig. 20 -

1) every 100 hours of operation.

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

hot during operation. Allow the engine to cool completely before ser-

vicing the spark arrestor.

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

cover.

3. Remove the screw that holds spark arrestor (Fig. 20 - 1) to muf-

ﬂer.

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 the gasoline has drained fully, close the carburetor drain screw, turn the engine switch to 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.
