Check the Aftertreatment Exhaust Piping

WARNING!
Never operate a machine with a damaged or defective exhaust system, exhaust leaks, or
restrictions. Failure to follow this warning could result in death or serious injury.
CAUTION!
Make sure that the engine is off and that the exhaust components have cooled so they can be
touched without burning. Failure to do so could result in injury.
1. Prepare the machine for service. See "Maintenance
Safety" on page 2-8.
2. Open the engine cover.
3. Locate the exhaust system (2) under the engine cover,
next to the engine.
4. Inspect the exhaust system and its mount for leaks or
signs of damage.
5. Check the connection to the expansion pipe (1) for leaks
or signs of damage.
6. Make sure the exhaust pipe is clear and not restricted.
