WARNING!
READ THE INSTRUCTION MANUAL COMPLETELY BE-
FORE ATTEMPTING MACHINE OPERATION!
The following steps are intended as a ba-
sic guide to help in the operation of this
equipment.
A. FAMILIARIZATION WITH EQUIPMENT
Take a walk around the machine. Take notice of all the major
components on the machine like the control handles, the
engine, the strike tubes and the truss sections. Look at the
machine construction. Check the fuel and hydraulic sys-
tem. Look at the engine and find the oil dipstick. Check the
oil levels in the engine and hydraulic tank. Make sure the
machine has fuel enough for the planned operation.
While seated in the operator’s position, note the locations of
the controls. On the left is the electric box with four switches
which were described in the startup section of this manual.
Just above the electric box on the left is the speed control
lever for the drive tubes.
In the center are the levers of the stack valve which operate
the drive tubes forward and reverse on both ends and finally
on the right side is the lever for running the strike tubes. The
speed of the strike tubes depends on the how far you push/
pull the lever. The cable from this lever is attached to the
hydraulic pump lever on the power unit.

B. FIRST MACHINE OPERATION
Now, following the startup procedure found in the “Machine
Start-up and Operation” section of this manual, start the
engine and let it warm up. Remember that when warming up
an engine, let the engine idle. When the engine is warm, test
the kill switch. The engine should die and the key should not
crank the engine with the emergency kill switch down.
Restart the engine. Before operating the roller screed, check
for people around the machine. As a suggestion, imagine a
rectangle that envelopes the entire machine. Never let any-
one into that rectangle while you are operating the machine.
Always be aware of your surroundings.
Practice running the roller screed in a straight line. As you
become comfortable maneuvering the roller screed, try turn-
ing off one side of the drive tubes and then the other. This
adjusts how parallel the screed moves with the forms, and
also allows you to steer around the columns.
C. CONCEPTS FOR USE OF ROLLER SCREED
The purpose of the roller screed is to strike off the surface of
the concrete at a predetermined grade. The quality of
screeding has a big effect on floor levelness and flatness.
This machine was designed to be able to go back and forth
on the forms, working the concrete to the desired grade.
The strike tube rotation should always push the concrete
forward into the areas that don’t have concrete yet.
Depending on the slump of the concrete, several passes
might be required for the right strike off grade. On the last
pass over the concrete, rotate the strike tube in the opposite
direction and go slowly forward. This leaves a thin layer
which can be easily bull floated.
