SPARK ARRESTOR MAINTENANCE

NOTE: Pay close attention when disassembling the muffler so you can put it back together correctly. Failure to do so will damage the unit and may cause serious personal injury.

1.Remove air filter/muffler cover. Refer to Removing the Air Filter/Muffler Cover (p. 8).

2.Locate the muffler, but do not remove it. Find the screw on the bottom of the muffler (Fig. 19). This screw holds the Spark Arrestor Hood Assembly and the spark arrestor screen to the bottom of the muffler. Remove this screw using either a Torx T20 or flat blade screwdriver.

3.Using a small flat blade screwdriver, carefully pry up the spark arrestor screen from the recessed hole, taking care to notice that the “raised” part of the spark arrestor screen is inside the recessed hole. Remove the spark arrestor screen from the muffler.

4.Clean the spark arrestor screen with a wire brush. Replace it if it is damaged, or if you are unable to clean it thoroughly.

5.Reinstall the spark arrestor screen by putting the “raised” portion of the screen inside the recessed hole of the muffler. Make sure that the spark arrestor screen fits flat against the muffler.

6.Place the spark arrestor plate on top of the spark arrestor screen with the raised side up and the opening facing toward the engine (Fig. 19)

7.Place the spark arrestor hood on top of the spark arrestor
