Abstract
A chain saw unit has a sub-frame defining a plurality of mount locations and a plurality of operating components amongst which are at least: a) a battery operated motor; and b) a battery for operating the motor. The plurality of operating components is each operatively placed and maintained at one of the mount locations such that the sub-frame assembly and operatively placed operating components together make up at least part of a main operating unit to which a chain bar and cutting chain can be operatively assembled. The main operating unit has an exposed surface area. An outer housing assembly overlies the exposed surface area and defines an outermost exposed surface. The plurality of operating components are operatively maintained on the sub-frame assembly independently of the outer housing assembly.
