ABSTRACT:
The invention is directed to a motor-driven apparatus such as a motor-driven chain saw or the like. It includes a lubricating-oil pump and an oil supply for a work tool and is equipped with a device for interrupting the supply of oil to the tool. This facilitates use of the chain saw apparatus with an accessory attachment work tool such as a hedge trimmer, drilling tool or the like for which a flow of lubricating oil is unnecessary.
