Abstract: A charger is provided with a housing comprising an intake port and an exhaust port. A battery interface is disposed on the housing and is configured to removably receive the battery pack. A charging circuit is disposed within the housing and is configured to supply charging power to a battery pack attached to the battery interface. A blower is provided for introducing air into the housing through the intake port and exhausting air from the housing through the exhaust port. The housing is configured to be mountable on a wall extending in a vertical direction. The exhaust port is located higher in the vertical direction than the intake port when the housing is mounted on the wall.

Abstract: In one aspect, the present disclosure discloses a charging system including a battery pack and a charger. The battery pack includes a first battery pack terminal, a second battery pack terminal, and a third battery pack terminal. The second battery pack terminal is spaced apart from the first battery pack terminal in an intersecting direction. The intersecting direction intersects a removal direction of the battery pack from the charger. The charger includes a first charger terminal, a second charger terminal, and a third charger terminal. The second battery pack terminal is arranged so as to pass through an area spaced apart from the third charger terminal in a process of removing the battery pack from the charger.

Abstract: A work tool includes a motor, a driving mechanism, a body housing and a handle. The driving mechanism is configured to perform an operation of linearly reciprocating the tool accessory along a driving axis extending in a front-rear direction. The handle includes a grip part extending substantially in an up-down direction, and a battery-mounting part provided on a lower side of the grip part. An upper end portion of the handle is connected to a rear end portion of the body housing via an elastic member so as to be movable relative to the body housing. A lower end portion of the handle is connected to the rear end portion of the body housing so as to be rotatable relative to the body housing, around a rotation axis extending in a left-right direction. The rotation axis is located on a lower side of the battery-mounting part.

Abstract: A push cart includes a wheel, a motor, an obstacle detector, and a controller. The motor is configured to generate a rotational force that rotates the wheel. The obstacle detector is configured to detect an obstacle. The controller is configured to execute, in response to detection of the obstacle by the obstacle detector, avoidance control to control driving of the motor such that a movement of the push cart is limited. The controller is configured to disable execution of the avoidance control in response to a determination that a specified disabling condition is satisfied.

Abstract: A work tool includes an elongate outer housing, an elongate inner housing, a motor, a spindle, and a transmitting mechanism. The inner housing includes a first end part, a second end part, an extending part and an elastic connection part. The motor, the spindle and the transmitting mechanism are disposed in the first end part of the inner housing. The first end part is connected to the outer housing via a first elastic member. The second end part includes a power-source-related device configured to enable power supply from a power source to the motor. The elastic connection part includes second elastic members connecting the extending part and the second end part. The second elastic members are spaced apart from each other in a circumferential direction around the longitudinal direction.

Abstract: An adapter connects a plurality of first battery packs, each having a nominal voltage of about 18-36 volts, in series to an power tool having a rated voltage that is 36 volts or higher. The power tool includes a second battery interface configured to removably attach a second battery pack. The adapter includes a plurality of first battery interfaces configured to removably attach the plurality of first battery packs and having a different physical configuration than the second battery interface. A connector of the adapter is configured to be removably attached to the second battery interface. A plurality of visual indicators is disposed on the adapter such that they have the same or substantially the same illumination direction and they visually indicate at least a level of charge of each of the first battery packs attached to the adapter.

Abstract: A grinder includes a motor, a housing, a spindle and a cover. The spindle protrudes downward from the housing, is driven by the motor, and thereby rotates. The cover at least partially covers a tool accessory mounted on the spindle. The cover includes a first cover part and a second cover part. The first cover part is fixed to the housing and at least partially covers the tool accessory from above. The second cover part is held such that it is capable of moving relative to the first cover part. The grinder is configured such that the area of the tool accessory covered by the cover changes in accordance with the relative movement.
