A wireless charging system for a power tool includes a charging module, docking frame, and tool holder. The charging module has a charging surface and an inductive charging device for charging a power tool resting on the charging surface, and is mounted in the docking frame, which is mounted in a mounting interface of the tool holder such that the charging surface is at an angle. The tool holder further includes a holding portion extending from a downward portion of the mounting interface such that the holding portion transversely supports the power tool. A soft insert structure received in the holding portion forms an interference fit with the power tool and applies a load to the power tool toward the charging surface that urges the power tool to an optimal location for charging, relative to the inductive charging device.

A power tool includes a housing and a hook assembly. The hook assembly includes a hook support and a hook member. The hook support is rotatably attached to the housing for rotation about a first axis. The hook member has a shank portion and a hook portion. The shank portion defines a second axis that is transverse to the first axis and is configured to rotate with respect to the hook support about the second axis.

A power tool includes a working element, a motor, a motor actuator, a housing, a light emitting element, a locking element, and a switch element positioned between the housing and the locking element. The housing supports the motor, the motor actuator, and the light emitting element and movably supports the locking element. The light emitting element illuminates a work area around the working element, and the motor drives the working element when actuated by the motor actuator. The locking element enables operation of the motor actuator when in an unlocked position and prevents operation of the motor actuator when in a locked position. When in the unlocked position, the locking element operates the switch element to activate the light emitting element.

A wireless charging system for charging a tool includes a tool holder and charging module. The tool holder includes a mounting interface, a holding portion extending from the mounting interface, and at least one surface t configured to mount the tool holder onto a support surface, such as of a mobile structure. The charging module is mounted in the mounting interface, and includes an inductive charging device that wirelessly charges a tool resting on the charging module. The holding portion is configured to at least partially engage the tool and act as a transverse support relative to the mounting interface. The at least one surface can include a base of the tool holder for horizontal mounting, a side of the tool holder for vertical mounting, or two opposite sides of the tool holder for mounting on a mounting rail.

A wireless charging system for power tools and other devices includes a charging module, docking frame, and tool holder. When a device is placed on a charging surface of the charging module, the charging module is configured to wirelessly charge the device. The charging module can be mounted within the docking frame or the tool holder via a mounting interface, and the tool holder can be affixed to a rigid surface. The docking frame can also be attached to a rigid surface, or can be mounted within the tool holder as an intermediate piece. The tool holder is configured to support the charging module such that the charging surface is at an angle. This configuration optimally locates the device relative to the charging module and allows the charging surface to act as a resting surface for the device between operations.

A circular saw includes a motor, a blade, a blade guard, and at least one panel. The blade is attached to the motor so as to be driven by the motor during a cutting operation. The blade guard is configured to at least partially cover the blade. The blade guard includes a leading portion and a guard lower edge. The at least one panel is substantially composed of substantially transparent scratch-resistant material and is coupled to the blade guard. The at least one panel is coupled to the blade guard such that a lower edge of the panel is adjacent to the guard lower edge.

A power tool includes a housing and a hook assembly. The hook assembly includes a hook support and a hook member. The hook support is rotatably attached to the housing for rotation about a first axis. The hook member has a shank portion and a hook portion. The shank portion defines a second axis that is transverse to the first axis and is configured to rotate with respect to the hook support about the second axis. The hook portion extends in a radial direction from the shank portion. The rotation of the hook support about the first axis alters an orientation of the shank portion of the hook member with respect to the housing, and the rotation of the shank portion with respect hook support alters the radial direction of the hook portion.

A pneumatic nailer for use with a fluid source includes a housing, a cylinder, a first valve assembly, a piston, and a port assembly. The housing defines a storage chamber configured for fluid communication with the fluid source. The cylinder is configured for movement with respect to the housing between a first cylinder position and a second cylinder position. An inner side of the cylinder defines a sleeve chamber and an outer side of the cylinder and the housing defines an actuating chamber therebetween. The first valve assembly is connected to the cylinder and is configured to (i) to allow fluid flow from the sleeve chamber to the actuating chamber and (ii) to prevent fluid flow from the actuating chamber to the sleeve chamber. The piston has a piston head and a driver member extending from the piston head.
