Exhaust system
The exhaust system is a frequently overlooked component of an engine. It is important to make sure the muffler
is in good condition and free of blockage.
NOTE: A blocked muffler will result in poor performance. If a muffler is completely blocked, the engine may not
start.
Cleaning the engine
1.
To maintain a proper operating temperature and to keep the equipment looking good, all debris should be
removed from the engine.
2.
It is recommended to use compressed air to blow all of the debris off of the engine.
NOTE: A pressure washer may be used to clean outdoor power equipment but only after the unit has been
allowed to properly cool.
