Abstract
A handle for an electric floor polishing or burnishing machine comprising a centrally-mounted actuator with safety lock is disclosed. In one embodiment, the handle is generally T-shaped and has a centrally-mounted actuator, which offers an operator more control over the polisher or burnisher and allows for one-handed operation. In another embodiment, the handle also has a safety lock which prevents the accidental operation of the machine.
