Abstract
A knob sub assembly for adjusting bar clamp tension holding a chainsaw bar of a chainsaw to a chainsaw body of the chainsaw may include a cap, a nut and a feedback assembly. The nut may be threaded to facilitate engagement with a fixing post of the chainsaw body responsive to a transfer of torque from the cap to the nut when the cap is rotated by an operator. The feedback assembly may be disposed substantially between the cap and the nut to at least selectively transfer torque from the cap to the nut. The feedback assembly may provide feedback to the operator when a predetermined threshold of applied torque is reached.
