A power tool () is disclosed comprising a tool (), a power source () arranged to power the tool (), a throttle lever (), a circuit board (), and a human machine interface () comprising components () arranged on the circuit board (). The power tool () further comprises a magnet () operably connected to the throttle lever (), and a sensor arrangement () configured to sense the intensity of the magnetic field of the magnet (). The sensor arrangement () is arranged on the circuit board ().

Hand held power tool with a human machine interface

A lubrication monitoring arrangement () is disclosed configured to monitor a supply of lubricant in a lubrication system () of a hand-held cutting tool (). The arrangement () comprises a heating element () and a control unit (). The heating element () is arranged to heat a portion () of the lubrication system (). The control unit () is configured to monitor the supply of lubricant in the lubrication system () by monitoring the change in temperature of the portion () of the lubrication system (). The present disclosure further relates to a hand-held cutting tool (), and a method () of monitoring a supply of lubricant in a lubrication system () of a hand-held cutting tool ().

Lubrication monitoring arrangement, hand-held cutting tool and method

A handheld power tool comprises a cruise control actuator (), which is mechanically connected to a controller input actuator () so as to variably move the controller input actuator () in a trigger direction (T) based on the position of the cruise control actuator (). The cruise control actuator () is movable between a plurality of different, stable cruise speed positions, in which the cruise control actuator () is connected to said controller input actuator () in a unidirectional manner to allow a trigger () to move the controller input actuator () even further in the trigger direction (T) without moving the cruise control actuator (). The cruise control actuator () is also movable to an 'OFF' position in which it mechanically blocks the trigger () from moving the controller input actuator () in the trigger direction (T). Suggested figure for publication.

Cruise control of portable garden or forestry tool

A blower may () include a power unit and fan assembly powered by the power unit, a stepless trigger (), control circuitry configured to at least partially control application of power to drive the fan assembly based on a position of the stepless trigger (), and one or more buttons. 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 ().

Blower with cruise control and boost function

A blower () may include a housing (), a motor (), a fan assembly () and an inlet assembly (). The housing () may include a handle () operably coupled thereto. The fan assembly () may be operably coupled to the motor () to force air through a blower tube () responsive to operation of the motor (). The blower tube () may define a tube axis (). The inlet assembly () may provide a path for air to the fan assembly (). The inlet assembly () may include an inlet aperture () formed at an end of the housing (). The inlet assembly () may further include an inlet mesh () disposed within the housing () spaced apart from the inlet aperture ().

Blower with improved sound reduction

A blower () may include a housing (), a blower tube (), a fan assembly () and an eyelet (). The housing () may include a handle portion () defining a handle aperture (). The blower tube () may extend forward from the housing () and define a tube axis (). The fan assembly () may be operably coupled to the blower tube () to force air through the blower tube () responsive to operation of a motor (). The eyelet () may be disposed on a side portion of the housing () proximate to the handle aperture ().

Blower comprising an eyelet

A blower may include a housing, a motor, a fan assembly and an aperture array. The housing may include a handle portion, a top wall and a bottom wall. The fan assembly may be operably coupled to the motor to force air through a blower tube responsive to operation of the motor. The blower tube may define a tube axis. The aperture array may be provided at a portion of the housing to provide a path for air to the fan assembly. The aperture array may be defined by a plurality of vanes disposed at a portion of the housing between the top wall and the bottom wall. The vanes may be angled downward relative to the handle portion.

Noise reduction system for a blower

A method of cooling blower components may include rotating a fan assembly () responsive to operation of a motor (). The rotation of the fan assembly may create an underpressure region in an inlet portion () and an overpressure region at a main channel () of the fan assembly (). The method may further include drawing air into the inlet portion () through a control unit housing portion () of a housing () of the blower () to cool a control unit () of the blower (), drawing air into the inlet portion () through a battery compartment () to cool a battery () of the blower (), and pushing air from the main channel () through a motor housing () to cool the motor ().
