Set-up Methods
These instructions describe four ways to
set up: height adjustable legs, trivet, rod
and crossbrace, or above ground on a
tripod.
Height Adjustable Legs
The adjustable legs can be used to set up
in a manhole base, pipe, invert, or open
cut.
Manhole Base Set-up
1. Prepare laser for use: Attach leg
set with centerline leg at front and
two side legs at rear. Apply power,
center the line adjustment, and enter the desired grade.
2. Transfer elevation from the hub to the manhole base.
3. Ser the front (centerline) leg to the desired height: After determining the desired beam
height above the manhole base, adjust the front leg so the beam will be projected at
that height.
4. Set the unit in place: Position the point of the front leg on pipe centerline, 2 inches (5
cm) in front of the manhole center, toward the pipe being laid for accurate alignment.

5. Roughly level the instrument by loosening the rear leg knobs and sliding the unit up or
down, then tighten.
6. Align laser to the forward manhole (see previous section on “Alignment”).
7. Recheck for level and accurate grade setting and proceed to lay pipe.
In-the-pipe Set-up
When setting up in-the-pipe, be sure the joint of pipe used for the set-up I accurately placed
for line and elevation.
Set-up in 6 inch (150 mm) pipe:
1. Remove the handle/rod mount and legs, if attached. Apply power, center the line
adjustment, and enter the desired grade.
2. Slide the unit into the pipe. It should rest on the three fixed short leg points of the
housing. Rough level the unit in the cross axis direction is necessary, using the cross-
axis level vial indicator on the display.
3. Align the beam to the forward manhole using the remote line control, or the line
adjustment buttons on the unit.
Set-up in 8 inch (200 mm), 10 inch (250 mm), and larger pipe:
1. Remove the handle/rod mount and legs, if attached. Apply power, center the line
adjustment, and enter the desired grade.
