Grade Reverse Mode
Note: After you’ve finished grading one side of the road, you can reverse the
sign of the ∠ axis from the cab using the radio remote control.
1. Set the blade on a known elevation hub on the centerline of the road.
2. Select “Grade Reverse” from the operational menu using the radio
remote mode button.
3. Press the enter button to confirm the selection.
Note: On the one-way radio remote control, “Reversing” appears in the radio
remote control’s LCD to indicate that the process is occurring and the sign
of the axis will be changed.
Note: When grade reversing has been completed, “Grade Reversing
Complete” appears in the LCD. If “Grade Reversing Unconfirmed” appears
in the LCD, check the distance between the laser and radio remote control
and try reversing the grade again.
Note: On a two-way radio remote control, the sign of the grade display
reverses to indicate that grade reversing has been completed.
Practical Application for Axis Alignment Mode: Steep Grades Setup
(Embankments, Waste Dumps and Sea Walls)
1. Set up a tripod on an established offset from the baseline of the bank to
make sure that the laser beam will be at the required height above the
bank surface. Make sure that one of the tripod legs is aligned with the
down-grade side of the ∠ axis.
2. Connect the steep-grade adapter to the tripod.
3. Adjust the steep-grade adapter to the desired grade value.
4. Align the adapter with the direction hub on the top of the bank.
5. Connect the laser to the steep grade adapter making sure that the laser’s
handle is parallel with the baseline of the bank.
6. Make sure the desired slope and rotation speed are entered into the
laser.
7. Using the sighting guides as a guide, rough align the laser with the
direction hub.
8. Connect a receiver and radio remote control to a grade rod.
9. Set the grade rod on the direction hub.
10. Slide the receiver up/down the grade rod until the receiver’s LCD
shows an on-grade reading.
