OPERATION

The following steps are intended as a basic guide to machine operation, and are not to be considered a complete guide to concrete finishing. We suggest that all operators (experienced and novice) read “Slabs on Grade” published by the American Concrete Institute, Detroit, Michigan. Read the “Training” section of this manual for more information.
