The PlaneLok mode can be activated in horizontal and vertical automatic and
manual mode. In PlaneLok mode when set up horizontal, the beam will be
locked to a fixed elevation point (up to 150 m (490 ft) located on one
axis at each side of the laser. For keeping vertical alignments fixed to a
direction point, PlaneLok can be used in both directions on the X-axis.
1. Set up the laser over the reference point.
2. Attach the HL760 receiver to a grade rod. Place the receiver at the second point and adjust it to the
On-grade position. The receiver should be permanently mounted at this location and at the desired
elevation.
3. Use the sighting guides on the top of the laser to align the laser to the receiver. Turn the laser on the
tripod until it is roughly aligned to the receiver’s position (the alignment range on both axes is +/-40).
4. Press and release the MENU button at the Standard Display and select PlaneLok.
5a. When set up horizontally, press and release button 4 to open the PlaneLok submenu; select the
desired PlaneLok axis then press button 4 to start PlaneLok.
Note: The laser starts to search for the receiver. A flashing Receiver and
Lock symbol appears at the selected axis and becomes solid when
PlaneLok has been completed.

(Y only with GL622N)
Note: When used in vertical mode, the receiver has to be placed with the photocell on the bottom side.
The HL760 display shows a flashing –PL– during the time the laser is searching and adjusting the beam to the
on-grade position.
When PlaneLok is complete, –PL– stops flashing at the HL760 display.
Note: The laser continues to servo to the receiver’s signals.
6. Exiting of PlaneLok can be done by pressing button 3 (ESC).
Note: If the setup will be disturbed for a minute (beam will be blocked),
an Alert comes up. After deleting the error message with button 4 PlaneLok needs to be started again.
It’s recommended to use the batter board adapter M402 for setting up the GL6X2N and the 105516 vertical
adapter for setting up the HL760.
Automatic PlaneLok mode
Steep Slope using PlaneLok
Set up the GL6X2N at the bottom part of the steep slope
area using the slope bracket (M401 laser tilting base).
Check the laser beam elevation and place the receiver at the
desired hub.
Change the GL into manual mode and tilt the unit to the
approx. steep slope position until the receiver on top starts to
catch the beam.

Steep Slope using PlaneLok
Select PlaneLok at the menu and start automatic PlaneLok by pressing button 4.
The transmitter starts searching for the receiver HL760 and locks the beam at the on-grade
position.
The Grade Match mode can be activated in horizontal automatic mode.
In Grade Match mode, the laser can be used to measure the existing grade value between two known
elevation points (up to 150 m (490 ft) located on one axis at each side of the laser
1. Set up the laser over the reference point.
2. Attach the HL760 receiver to a grade rod. Check the laser’s elevation next to
the laser then position the receiver at the second point WITHOUT changing the
receiver’s elevation on the rod.
3. Use the sighting guides on the top of the laser to align the laser to the receiver.
Turn the laser on the tripod until it is roughly aligned to the receiver’s position
(the alignment range on both axes is +/-40°).
4. Press and release the MENU button at the Standard Display and select Grade Match.
5. Select the desired Grade Match axis then press button 4 to start Grade Match.
Note: The laser starts to search for the receiver. A flashingReceiver an angle symbol
appears at the selected axis and disappears when Grade Match has been completed.
While the laser is searching and adjusting the beam to the on-grade position,
the HL760 display shows a flashing –GM–. When Grade Match has been completed,
the HL760 goes back to the standard elevation display. The remote control as well as the laser
will display the final measured grade value.
Note: If Grade match can’t be completed by checking the limits, the laser comes with an
Error message (Grade Match has Failed) which can be deleted with button 4 (OK).
Automatic Grade Match mode
(X only GL622N)
Automatic Axis Alignment mode adjusts automatically the direction
the grade axis is pointing to the receiver’s location by an electronically
simulation of rotating the unit on its base to match the hub.
Using Axis Alignment, the laser axes can be aligned to one
direction hub (up to 150 m (490 ft) located on one axis at each
side of the laser.
1. Set up the laser over the reference point.
2. Place the grade rod with the attached HL760 receiver at the desired direction hub.
3. Use the sighting guides on the top of the laser to align the laser to the receiver.
Turn the laser on the tripod until it is roughly aligned to the receiver’s position.
(the alignment range on both axes is +/-40°).
4. Press and release the MENU button at the Standard Display and select Axis Align.
5. Adjust the receiver into the beam before starting the automatic Axis Alignment to reduce the
time needed for finishing the alignment.
5. Select the desired axis then press button 4 to start Axis Align.
Note: The laser starts to search for the receiver while -AA- is flashing at the HL760 LCD.
Note: A flashing Alignment symbol appears at the selected axis, becomes
solid when Axis Alignment has been completed and then disappers while
the flashing bubbles come back. A short line on top of Y and X
confirms an Axis Alignment has been completed.
