Patent ID: 7082639

Claim:
An apparatus associated with a surface maintenance machine, including a machine frame, for maintaining a selected pattern of a work tool upon a work surface, wherein the work tool includes a medium exhibiting an effective working length that determines the selected pattern of the work tool upon the work surface when selectively engaged with the work surface, the apparatus comprising: a transportable frame assembly, including a transportable frame member, mechanically coupled to the machine frame for supporting the work tool; a settable actuator for selectively positioning said transportable frame member relative to said work surface for selectively engaging the work tool with the work surface; first indicia having graduated markings and disposed in a location proximate said work tool so as to provide an indication of the current effective working length of the work tool medium; and second indicia, disposed in a location proximate said settable actuator, said second indicia having graduated marking corresponding to said graduated markings of said first indicia so that the actuator is settable to achieve a selected pattern of the work tool upon the work surface when engaged with the work surface in relation to said indication of the current effective working length of the work tool medium.
