User Manual
2. Using the sighting guide as a guide, rough align the laser with one of the
slope-control hubs.
Note: The two slope-control hubs must be in lines that are at a 90° angle
from one another.
3. Enter the approximate grade into the axis that needs to be aligned and
an exact grade value into the other axis.
Note: The automatic slope searching range is ±1.5%. The approximated
grade should be within 1.5% of the final matched grade.
4. Connect a receiver and radio remote control to a grade rod.
5. Set the grade rod on the elevation-control hub.
6. 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.
7. Go to the slope-control hub on the axis to be aligned and set the grade
rod on the hub. Make sure you DON’T change the height of the
receiver on the grade rod.
8. Select “PlaneLok” from the operational menu using the 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 in the LCD.
Note: Note: When the PlaneLok function has been completed, “PlaneLok
Complete” and a “Lock” icon (padlock symbol) appear in the radio remote
control LCD.
Note: Alignment can take 1 to 5 minutes to complete.
Note: If the PlaneLok function fails, the remote indicates the cause of failure.
See the ‘Troubleshooting” section of this manual for more information.
Note: The receiver should be permanently mounted at this location and at the
desired elevation. Use a bipod (commonly used with prism poles) to hold the
grade rod steady for the entire workday.
Note: The resultant grade on the locked axis is displayed in the remote LCD.
Note: The laser continues to servo to the receiver’s elevation signals. Any
loss of signal over an extended period of time (1 minute) causes the laser
beam to turn off and rotor to stop. The PlaneLok mode must be reactivated
when the laser experiences loss of signal over an extended period.
