ABSTRACT:
This disclosure is directed to a portable handheld power-driven tool such as a cutoff machine. The cutoff machine includes an engine having a drive shaft. A drive wheel for the work tool is provided at one end of the drive shaft and a fan wheel for moving cooling air to the engine is mounted at the other end of the drive shaft. A pull rope starter is mounted at the power takeoff end of the drive shaft so that it lies outside of the flow of cooling air. In this way, abrasive dust is prevented from accumulating on the pull rope starter and its operational service life is significantly increased.
