Set-Up for Level Grading
If the job site is to be level, the set-up of the
Rotating Laser is simple. Since no slope is required
in either axis, the Rotating Laser does not need to
be aligned. The Rotating Laser will provide a level
plane of laser light in all directions.
1. Locate the Rotating Laser following the
guidelines above.
2. Apply power to the Rotating Laser. Level the
Rotating Laser (some Rotating Lasers will
automatically level, others will need manual
adjustment).
3. Set the counters for both axis at 0.000% (If
needed, see the Rotating Laser Operation
Manual).
4. Bench the machine. See the “Benching and
Operating” procedure in this section.
Set-Up for Sloped Grading
If the job site is to be graded for a single or dual
slope, the Rotating Laser requires its axis to be
aligned for the job site. The Rotating Laser will
then provide a plane of laser light at the required
slope(s).
The following procedures are for two typical
examples of job sites requiring sloped grades.
Remember, each job site is unique, so consider the
following methods as guidelines and not as the only
methods possible.
Method One:
1. Set a minimum of two grade stakes exactly
in line with one of the axis to be graded
(Refer to Figure 6).
2. Place the Rotating Laser in line with the two
grade stakes.
3. Switch on the Rotating Laser. Level the
Rotating Laser (some Rotating Lasers will
automatically level, others will need manual
adjustment).

Stakes
4. Set the counter on the Rotating Laser for
both axis to 0.0000% (If needed, see the
Rotating Laser Operation Manual).
5. Roughly align one of the axis to the grade
stakes by sighting over the top of the
Rotating Laser (Refer to Figure 7).

6. Align the plane of laser light.
a. Set a grade rod with Rod Eye Receiver
on the far grade stake and adjust the rod
until the Rod Eye Receiver indicates “On
Grade.”
b. On the axis not aligned with the stakes,
enter on the Rotating Laser: 5.000%.
Allow the Rotating Laser to level itself to
this new position, if needed.
c. Check the Rod Eye Receiver again.
• If the Rod Eye Receiver indicates
“On Grade”, the plane of laser light is
aligned correctly.
