Zusammenfassung:	A blower may include a housing having a handle, an electric motor powered by a battery pack, and a fan assembly operably coupled to the electric motor to force air through a blower tube responsive to operation of the electric motor. The blower tube defines a blower tube axis. The fan assembly creates a low pressure area in a intake chamber that provides the air to the fan assembly. The air enters the intake chamber via at least one radial entrance and an axial entrance disposed in the housing. The axial entrance is configured to receive cooling air that has passed through the battery pack.
