Systems Features and Basic Operation
If the job site is to be level, the
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.
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).
Figure 6. Method One: Align Rotating Laser with Grade 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.
