Operation Tips for Power Trowels:
The Floating Operation must be done with the blades free of any cement. Blades must be in a flat position to the surface. The slab is ready for finishing when the operators footprints leave minimal impressions. Use a standard trowel followed by an edger trowel near walls and obstructions that cannot be reached by your power trowel. When surface has set sufficiently, continue to the Finishing Operation.
The Finishing Operation is started after the floating operation is complete and the blades are cleaned. Adjusting blade pitch with the tilt knob controller allows for unlimited variation to compensate for uneven hardness across the slab, as it may cure at varying rates. Start the pitch at approximately 1/4 inch for the first pass and continue increasing pitch on each following pass until desired finish is achieved.
