MAINTENANCE

Exhaust Silencer Cleaning

Do not perform clean out immediately after the
engine has been run, as the exhaust system
becomes very hot. Serious burns could result
from contact with exhaust components.
To reduce fire hazard, make sure that there are
no combustible materials in the area when
purging the exhaust silencer.
Wear eye protection.
Do not stand behind or in front of the vehicle
while purging the carbon from the silencer.
Never run the engine in an enclosed area.
Exhaust contains poisonous carbon monoxide.
Do not go under the machine while it is inclined.
Set the hand brake and block the wheels to
prevent roll back.
Failure to heed these warnings could result in
serious personal injury or death.
The exhaust silencer must be periodically purged of
accumulated carbon as follows:
1. Remove the clean out plug on the bottom of the silencer.
2. Place the transmission in park, and start the engine.
3. Purge accumulated carbon from the exhaust system by
momentarily revving the engine several times.
4. If some carbon is expelled, cover the exhaust outlets and
lightly tap on the silencer around the clean out plug with a
rubber mallet while revving the engine several more times.
Wear protective gloves when covering the
exhaust outlets. Serious burns could result from
contact with exhaust components.
