ABSTRACT:
A belt tension system for a power tool such as a demolition saw. The system includes a driven gear and a drive gear. The drive gear is orientated perpendicular to the driven gear for more convenience access to adjust the driven gear and, hence, adjust the drive belt. The driven gear can include a second member movably connected to a first member. The second member has a threaded portion and a shaft portion. The first member has helical grooves to interact with the drive gear and a center hole with the second member shaft portion slidingly located therein. The first member can axially rotate the second member when it is axially rotated.
