At the end of the placement, while you’re working your way to toward the exit, remember to think ahead.
Stick to the route you decided on during planning and particularly, as you get close to the end, make
sure that the rest of the placement crew always knows where to dump concrete before your next pass.

LASER SYSTEM SETUP LIST

1) Begin by setting the transmitter up in the beginning of the placement in the best possible locations
(eliminating as many column blocks as possible) approx. 6 feet above floor elevation.
2) Attach the screed head to the lift arm.
3) See page 25 for warm up procedure.
4) Slide the 2 receiver poles into the screed head assembly.
5) Attach the 2 receivers onto the receiver poles, receiver LED’s should be pointed toward the control
panel.
6) Attach the receiver cord from the receiver to the control box on both sides.
7) Verify that the laser system is turned on and working properly. Turn the auto/manual switch to
manual. Raise and lower both sides using the manual switches to verify the system is working porperly.
8) Set the grade stick to the benchmark, do you walk around inspection of the placement verifying that
the grade stick is matching up to all forms, previous screeded concrete, diamonds, and anything that
will be on grade.
9) Start placing the concrete in the best known location. Wherever the screed will start screeding needs
to be on grade. Example: If the first pass of the screed will be against and exterior wall edge this wall
edge needs to be troweled/magged to the proper elevation this procedure will make the setup of the
screed easier and more accurate.
10) Drive the screed into the first pass position.
11) Level the machine.
12) Make sure the laser control system is in the manual position.
13) Instruct a coworker to hold the grade stick on the plow facing the laser transmitter. When doing the
setup, the screed Grade Rod should be held as closely as possible to the linear actuators.
14) At the operator console raise or lower the plow using the manual switch for that side until the grade
stick/handheld receiver indicate that the plow is at the proper elevation. Repeat this same process for
the opposite side. Recheck both sides.
15) Once the plow is on-grade, manually lower the laser receiver (from the top down) until the LED’s
indicate the on-grade signal, repeat the process for the opposite side.
16) Turn the laser control system into the auto mode.
17) Proceed to screed the first 6 feet of the pass.
18) Check the actual screeded surface of the concrete on both sides of the pass.
19) Make the necessary adjustments, if the grade stick is showing that the grade is high or low, use the
“Jog” feature.
20) Rescreed the pass at the new elevation and recheck the elevation with the grade stick. If changes
are needed once again, follow the same process as above.
