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.
NOTE: Mice and other critters tend to build nests inside the engine shrouds while the snow blower is stored
during the long off season.
