Abstract
An adjustable handle assembly for a road surface cutting saw is provided that includes a back plate attached to the saw housing, an outer gear attached to the back plate, a bracket assembly including an inner gear, a tubular member slidably attached to the bracket assembly, and an adjustment lever having a threaded engagement end. The adjustment lever secures the bracket assembly to the saw such that the inner gear engages the outer gear. When the adjustment lever is loosened a bias spring biases the bracket assembly away from the saw such that the inner gear disengages from the outer gear to thereby allow rotation of the handle assembly to a desired operating position.
