exactly with the line pivot LED.  Repeat step 2 and 3 until the vertical crosshair is on 
both the forward manhole marker and the line pivot LED on the unit.

3. Align the Laser Beam to the Transit – Place a target in the ditch approximately 15’ 

(5m) in front of the laser.  Looking through the transit at the target, adjust the beam left 
or right using the alignment buttons on the remote control until exactly centered on the 
vertical crosshair.  The transit should then be able to swing from beam, to line pivot 
LED, and to forward manhole marker, with each being aligned to the crosshair (Figure 
D),  Repeat steps 2,3, and 4 if necessary.  When all three are accurately aligned, pipe 
laying can proceed.

Aligning the beam with a standard transit

Align the transit over the instrument – Mount the 
standard transit to the transit mount at the end of 
the arm.  Using a plumb bob, adjust the arm so the 
transit is directly over the centerline of the pipe.  
Level the transit.  Position the laser so the line 
pivot LED is exactly under the plumb point.
Align the Transit to the Forward Manhole – Pivot 
the transit until the vertical crosshair splits the 
forward manhole marker.
Align to the beam using step 4 above.

Special Transit Method

This method uses the Rod and Crossbrace 
system.  The laser is mounted with the 
Handle/Rod Mount. (Figure F)

1. Mount the Special Transit – With the rod 

plumbed, and the laser leveled, mount the 
Special Transit on the rod. Position the 
transit where it is possible to see the 
forward manhole marker, yet as low as 
possible on the rod.  Secure the rod mounting bracket with the secure knob.

2. Align Transit to Forward Manhole – Use the forward marker knob to adjust the vertical 

crosshair until it is aligned with the forward manhole marker.
