Working techniques
The floating operation removes dents on the concrete
surface. The concrete surface must be sufficiently hard
before the floating operation. The concrete surface is
sufficiently hard when a shoe gives not more than 3 mm/
0.12 in. deep recess on the concrete surface.
When the floating operation is completed, the concrete
surface is prepared for the troweling operation. The
troweling operation increases the density of the concrete
surface and makes it smooth and hard.
CAUTION: Look for loose stones on the
concrete surface during operation. Loose
stones can make marks that are not easy
to remove from the concrete surface.
To do the floating operation
1. Set the throttle control to an applicable speed.
CAUTION: Do not set the speed too
high. Too high speed on wet concrete
can cause damage to the surface. Adjust
the speed during the operation as the
concrete becomes harder.
2. Adjust the blade pitch until there is tension in the
blade pitch cable. Refer to To adjust the blade pitch
on page 13 .
