MAINTENANCE Exhaust Silencer Cleaning 5. If particles are still suspected to be in the silencer, back the machine onto an incline so the rear of the machine is 1 ft. (30.5 cm) higher than the front. Place the transmission in park and block the wheels. Repeat steps 3 and 4 (see WARNING). WARNING 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.

If rubber mounts are cracked or show signs of fatigue, replace them. 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. CAUTION Wear protective gloves when covering the exhaust outlets.
Serious burns could result from contact with exhaust components. 2.16
