Remove the plug (Item 1) [Figure 246] from the bottom
of the muffler.
When the engine is running during service, the
driving and steering controls must be in neutral and
the parking brake engaged. Failure to do so can
cause injury or death.
W-2006-1209
Start the engine and run for about 10 seconds while a
second person, wearing safety glasses, holds a piece of
wood over the outlet of the muffler. This will force
contaminants out through the cleanout hole.
Stop the engine. Install and tighten the plug. Close the
r
ear door.
AVOID INJURY OR DEATH
When an engine is running in an enclosed area, fresh
air must be added to avoid concentration of exhaust
fumes. If the engine is stationary, vent the exhaust
outside. Exhaust fumes contain odorless, invisible
gases which can kill without warning.

Stop engine and allow the muffler to cool before
cleaning the spark chamber. Wear safety goggles.
