ABSTRACT:
A handheld paving breaker includes a reciprocal chuck in a front head and an elastic spring for biasing the chuck toward the fronthead. The chuck can move longitudinally, but is restrained from rotation in the fronthead. A moil mounted in the chuck is biased against the work surface by the chuck, to provide better control of the moil, during start-up and operation. Wear pads between the spring and members against which the spring is seated improve spring life.
