<p>A random orbital sander has improved arrangements (24), (88), (90), (120) for resiliently supporting an air motor (32), controlling the flow of pressurized air to the motor and utilizing air exhausted from the motor to withdraw dust from a shroud (120) arranged to collect dust generated incident to the operation of the sander. Also disclosed is an alternative dust collecting arrangement wherein the shroud is connected by a sander-mounted duct (120d) to a vacuum source.</p> |
