Abstract

A pavement breaker has a housing, a hammer mechanism mounted within the housing, and at least one handle moveably mounted on the housing. The handle(s) can move in a vertical direction when the pavement breaker is orientated in its normal operation orientation. A sensor is mounted within the housing for detecting when the handle(s) is moved towards or at its uppermost position. If the sensor detects such handle position, the hammer mechanism is deactivated.
