The fan assembly may rotate at a speed proportional to the position of the stepless trigger () in a first mode of operation. The control circuitry may be configured to enable the operator to actuate a first button () of the one or more buttons to shift to a second mode of operation in which speed of the fan assembly is not proportional to the position of the stepless trigger () over at least a portion of a range of motion of the stepless trigger ().
