1. Remove the retaining screw and remove
the arrestor from the end of the muffler.
2. Use a non-synthetic brush to clean the

sary, blow debris from the screen with
compressed air.
3. Inspect the screen for wear and damage.
Replace a worn or damaged screen.
4. Reinstall the arrestor. Torque screws to
5-7 ft. lbs. (7-9 Nm).
