Abstract: A handheld power tool comprises a cruise control actuator (22), which is mechanically connected to a controller input actuator (27) so as to variably move the controller input actuator (27) in a trigger direction (T) based on the position of the cruise control actuator (22). The cruise control actuator (22) is movable between a plurality of different, stable cruise speed positions, in which the cruise control actuator (22) is connected to said controller input actuator (20) in a unidirectional manner to allow a trigger (20) to move the controller input actuator (27) even further in the trigger direction (T) without moving the cruise control actuator (22). The cruise control actuator (22) is also movable to an “OFF” position in which it mechanically blocks the trigger (20) from moving the controller input actuator (27) in the trigger direction (T).

Abstract: A blower may (100) include a power unit and fan assembly powered by the power unit, a stepless trigger (146), control circuitry configured to at least partially control application of power to drive the fan assembly based on a position of the stepless trigger (146), and one or more buttons. The fan assembly may rotate at a speed proportional to the position of the stepless trigger (146) in a first mode of operation. The control circuitry may be configured to enable the operator to actuate a first button (164) 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 (146) over at least a portion of a range of motion of the stepless trigger (146).

Abstract: A blower (100) may include a housing (110), a motor (120), a fan assembly (170) and an inlet assembly (160). The housing (110) may include a handle (140) operably coupled thereto. The fan assembly (170) may be operably coupled to the motor (120) to force air through a blower tube (150) responsive to operation of the motor (120). The blower tube (150) may define a tube axis (152). The inlet assembly (160) may provide a path for air to the fan assembly (170). The inlet assembly (160) may include an inlet aperture (162) formed at an end of the housing (110). The inlet assembly (160) may further include an inlet mesh (164) disposed within the housing (110) spaced apart from the inlet aperture (162).
