Abstract: A power tool includes: an electric motor; an energy storage device (a) that includes hybrid supercapacitors and (b) that has an energy density of at least approximately 150 watt hours per kilogram (Wh/kg); and at least one switch configured to selectively enable power flow from the energy storage device to the electric motor and to selectively disable power flow from the energy storage device to the electric motor.

Abstract: Power drive tools are described. The tools include one or more threading pawls, one or more release pawls, and a drive ring selectively positionable relative to the tool and engaged with the pawls to selectively extend or retract the pawls. Also described are tools that include one or more lights to illuminate a workpiece. Also described are tools having distally located shoulder regions at which force may readily be applied. In addition, gear train assemblies for use in the power drive tools are described.

Abstract: Battery charging systems having battery charging circuits are described. The battery charging circuit can be located within a battery housing. Alternatively, the battery charging circuit can be located within a charging shoe housing. Also described are power source modules. In addition, various methods of charging and discharging are described.

Abstract: Wheeled transport carts are described which are configured for transporting drain cleaning equipment such as drain cleaning machines and drain cleaning cable. The carts include engagement provisions that enable a drain cleaning machine to be affixed to the cart and preclude unintended separation from the cart during use or transport. The engagement provisions also enable the drain cleaning machine to be quickly and easily separated from the cart. Also described are methods of transporting such equipment using the carts. In addition, systems of the cart(s) with various equipment are described.

Abstract: Systems and methods are described for governing and monitoring operations of tools. The systems include a registration and control computer, one or more mobile devices, and one or more tools. The tools include electronic locking provisions which upon activation selectively enable tool operation.

Abstract: Various clutch adjusting assemblies for incorporating in drain cleaning machines are described. The assemblies enable adjustment or setting of a clutch in a drain cleaning machine without the use of tools.

Abstract: Pressing tools and jaws are described which include communication provisions that enable information concerning the jaws to be used with the press tool, to be transmitted to the tool. The press tool includes provisions that limit or otherwise tailor the output of the tool based on information concerning the jaws.

Abstract: Charge adapters for use with batteries and AC power adapters are described. Also described are systems and related methods using the charge adapters and particularly tool systems with detachable batteries.

Abstract: Augers that utilize a drain cleaning cable which can be rotated and selectively extended or retracted from the auger are described. The augers utilize coupling assemblies that enable easy coupling or decoupling between the drain cleaning cable and a torque transmission shaft of the auger.

Abstract: An extractor cleaning machine that includes a base movable along a surface to be cleaned, the base including a distribution nozzle and a suction nozzle. The extractor further includes a suction source in fluid communication with the suction nozzle. A recovery tank is in fluid communication with the suction source and the suction nozzle to receive the fluid drawn through the suction nozzle. The extractor further includes a supply tank including a first chamber for storing a first fluid, a second chamber for storing a second fluid, and a third chamber in fluid communication with the first chamber and the second chamber to receive the first and second fluids, the third chamber also in fluid communication with the distribution nozzle for supplying a mixture of the first and second fluids to the distribution nozzle.
