Operation
Before placing the ScreeDemon in concrete make sure the
clamps securing the exciter to the float blade are tight.
CAUTION
Keep the blade clamps tight at all times. Operat-
ing the ScreeDemon with the clamps loose will
damage the float blade.
CAUTION
Never run the ScreeDemon above idle when the
float blade is not in contact with concrete. This
can damage the float blade.
The ScreeDemon can be used with or without forms. The
following describes the use of the ScreeDemon without
forms.
1. Use a hand float to make a 12-18” diameter wet pad
(A) at the desired grade in the four corners of the area
you wish to screed. The outer extents of the wet pads
should not exceed the length of the float blade being
used.
NOTE: Use a laser receiver, transit level, or grade
stakes to help establish the correct grade.
2. Run the ScreeDemon between the wet pads to create
two parallel strips (B) that define the grade for the
remainder of the wet screeding. These strips should
be 12-18” wide.
3. Place one end of the float blade on each of the
parallel strips (B) and screed the concrete (C) in
between the strips. Be sure the float blade follows
the contour of the parallel strips.
