User Manual

The main uses for the laser in road construction are for planar sections where
the road design calls for no vertical or super-elevated curves.
Automatic Axis Alignment Mode
1. Set up the laser over a point on the centerline of the road.
2. Using the sighting guide as a guide, rough align the laser with the
direction hub on the centerline.
Note: Because the laser can provide positive and negative slopes in the ∠
axis, make sure the laser’s handle is at a 90° angle to the centerline of the
road.
Note: If there isn’t enough space for the laser setup on the centerline, the
laser can be set up on a line parallel to the centerline of the road (D1=D2).
3. Enter the grade value for the axis that aligns with the centerline of the
road (∠).
4. Enter the grade value for the side of the road to be graded first into the
axis that is perpendicular to the centerline of the road (∠).
5. Connect a receiver and radio remote control to a grade rod.
6. Set the grade rod on the centerline direction hub.
7. Slide the receiver up/down the grade rod until the receiver’s LCD
shows an on-grade reading.
Note: The grade rod MUST be plumb.
8. Select “Axis Align” from the operational menu using the radio remote
control’s mode button.
9. Select the axis (∠ or ∠) that you are aligning using the up or down
buttons.
10. Press the enter button to confirm the selection. “Start” then “Wait”
appears on the LCD.
11. Hold the grade rod plumb and steady during automatic axis alignment.
Note: Alignment can take from 1 to 5 minutes to complete.
Note: When axis alignment has been completed, “Axis Alignment Complete”
appears in the LCD. If axis alignment fails, a failure message appears in the
LCD.
12. Check the laser’s alignment and grade values using previously
established elevation-control hubs and slope-control hubs as
references.
