maintenance.
If the machine is not stored properly, there is a danger of fuel spoilage, the machine failing to start, or

●
When removing fuel, be sure that the engine and muffler have cooled before touching the
●
machine. There is a danger of burns. Also, take care to handle any removed fuel in a responsible
manner.
■Cleaning all parts
Clean the recoil starter, air filter, muffler, around the carburetor, and inside the belt cover by
