SYSTEMS FEATURES AND BASIC OPERATION

• If the Rod Eye Receiver indicates the

plane of laser light is too high or too
low, have a second person rotate the
Rotating Laser on the tripod in small

steps until the Rod Eye Receiver indi
cates “On Grade.”

7. Enter on the Rotating Laser the required

percent of grade for each axis and allow the
Rotating Laser to level itself again.

8. Bench the machine. See the “Benching and

Operating Your Machine” procedure in this
section.

Method Two:

NOTE: This procedure requires that the elevations

of the grade stakes are correct and aligned
to the slope or percent of grade required.

1. Set a minimum of two surveyed grade

stakes. The stakes must have elevation
information.

2. Place the Rotating Laser a few feet (meters)

behind the first grade stake and in line with
one of the far grade stakes (it is not critical
to align the Rotating Laser exactly). (Refer
to Figure 9.)

NOTE: Follow the guidelines at the beginning

of this section when placing the Rotating
Laser.

3. Switch on the Rotating Laser. Level the

Rotating Laser.

4. Roughly align one of the axis to the grade

stakes by sighting over the top of the

Rotating Laser (Refer to Figure 7).

5. Set both the counters on the Rotating Laser

to the required percent of grade (If needed,

see the Rotating Laser Operation Manual).

Figure 9. Method Two: Align Rotating Laser with Grade

Stakes

NOTE: The Grade Rod must be held plumb for

each of the readings taken in the following

steps.

Establish the H.I. (height of the instrument)

for the plane of laser light.

a. Align the bottom of the Grade Rod to the

mark on the near grade stake.

b. Adjust the Rod Eye Receiver up and down

until it indicates “On Grade.”

c. Adjust the Rod Eye Receiver for any cut

or fill amount indicated by the grade stake.

• If the grade stake shows a cut, extend

the Grade Rod and Rod Eye by the

amount shown as a cut.

• If the grade stake shows a fill, lower the

Rod Eye by the amount shown as fill.
