Abstract
A lubricating-oil pump is disclosed for a motor-driven apparatus such as a chain saw. The lubricating-oil pump delivers lubricating oil to a tool. The supply of lubricating oil from the oil pump to the tool can be interrupted. For example, in this way the flow of oil can be stopped when an accessory tool or the like is mounted on the motor-driven apparatus which requires no lubricating oil during operating.
