Abstract
A multi-tool () includes a power head () including a power head housing () having a handle () operably coupled thereto, a tool attachment () configured to perform a work function, the tool attachment () being alternately separable from and operably coupled to the power head (), a motor () disposed in the power head housing (), a battery () configured to be operably coupled to the motor () to selectively power the motor (), a power head mating interface () including structures disposed at the power head () for defining a physical mating assembly, a drive power transfer assembly and an electronic assembly, and a tool mating interface () including structures disposed at a housing of the tool attachment () for defining the physical mating assembly, the drive power transfer assembly and the electronic assembly. The structures disposed at the power head () and the structures disposed at the housing of the tool attachment () for defining the physical mating assembly are configured to contact each other before the structures disposed at the power head () and the structures disposed at the housing of the tool attachment () for defining the drive power transfer assembly contact each other responsive to operably coupling of the power head mating interface () to the tool mating interface (). The structures disposed at the power head () and the structures disposed at the housing of the tool attachment () for defining the drive power transfer assembly are configured to contact each other before the structures disposed at the power head () and the structures disposed at the housing of the tool attachment () for defining the electronic assembly contact each other responsive to operably coupling of the power head mating interface () to the tool mating interface ().
