Removing the Muffler
WARNING: Make sure the muffler is cool
before removing it from the housing to
prevent serious personal injury.
1. Remove the 10 screws holding the unit housing
together with a T20 Torx or flat blade screwdriver
(Fig. 31).
2. Locate the two (2) muffier mounting bolts that are
holding the heat shield and muffler to the engine.
Remove the two (2) bolts using a flat blade
screwdriver or 5/lé-inch socket or nut driver (Fig. 32).
NOTE: Do not remove the heat shield/muffler screw to
separate the top heat shield from the muffler.
The spark arrestor will be accessible without
removing the screw.
