Operating Modes

CUIDADO: Remove loose stones from the concrete surface before operation. Loose stones can leave marks that are difficult to remove.

Float operation removes indentations from the concrete surface. Ensure the concrete surface is sufficiently firm before float operation. Make a test indentation and ensure the shoe mark depth is less than 3 mm (0.12 in).

After float operation, the concrete surface is prepared for finishing. Trowel operation increases the density of the concrete surface, making it smooth and hard.

Moving the Product Correctly

Move the product straight across the concrete surface.

  • Float Operation: Start the first float pass at 90° to the leveling pass to remove imperfections left by the vibratory screeds. Overlap subsequent passes as needed for a flat floor. At the edge of the concrete surface, move the product sideways, then move backward to the opposite edge. Ensure at least 1/2 of the blade diameter overlap between passes. Turn the product slowly and carefully when operating near objects like pipes.
  • Finishing Operation: At the edge of the concrete surface, turn 180° and move the product directly to the opposite edge. Ensure at least 1/2 of the blade diameter overlap.

CUIDADO: Do not turn the product during float operation unless necessary, as this can displace wet concrete and cause damage to the surface.

Moving the Product with Direction Controls

CUIDADO: Do not push or pull the direction controls quickly or forcefully, as this can damage the controls and cause the product to jerk, damaging the surface.
