Attaching Blade
Refer to Figure 1.
1. Loosen the bolts that secure the clamps to the exciter
assembly.
2. Lay the float blade on the floor with the decals facing
upward.
3. Center the exciter between the “Exciter Location”
decals on the float blade.
4. Tilt the exciter forward and hook the small leg of the
clamping plates under the front lip of the float blade.
5. Set the exciter onto the blade so the rear part of the
exciter casting lines up with the rear cavity of the float
blade.
6. Tighten the clamping plate bolts.
Starting Engine
1. Turn engine switch to “ON”.
2. Press the primer bulb repeatedly until fuel can be
seen in the clear plastic return tube.
3. Choke engine if necessary (you may not need to
choke a warm engine).
4. Pull starter rope repeatedly until engine starts.
5. If choke was moved to the closed position to start,
gradually move it to the open position as the engine
warms up.
6. Allow engine to warm up for one or two minutes.

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.

Handle Adjustment
The operator can adjust the handle on the
ScreeDemon to a comfortable position.
Refer to Figure 2.
1. Loosen the handle by turning the handle
adjustment knob counter-clockwise.
2. Move the handle to the desired position.
3. Tighten the handle adjustment knob.
Kickstand
The kickstand will support the ScreeDemon in an
upright position when not in use.
Transporting
It is recommended to transport the ScreeDemon with the
float bar removed. The float bar is more likely to be
damaged if attached to the main unit during transport.
The handle can be collapsed for easier transport. See
Figure 3.
