Line (transit method)
1. Set a manhole mount and transit on the manhole.
2. Clamp the manhole mount base to the side of the manhole to
establish a stable transit support.
3. Secure the vertical arm into the manhole mount base.
4. Assemble the horizontal arm, horizontal clamp, and vertical
support clamp to the vertical arm and position over the top of
the Laser.
5. Attach your transit to the 5/8 x 11 (M16) threaded adapter in
the horizontal arm.
6. Transit Alignment:
You may position your transit over the Laser’s bulls eye target in one
of the following methods:
a. Optical Plummet: Use the Laser Plummet and if your transit is
equipped with an optical plummet, adjust the horizontal arm
to position the transit’s optical plummet over the Laser’s bulls eye
target.
b. Plumb Bob: If your transit does not have an optical plummet,
suspend a plumb bob from the transit, and align it over the Laser’s
bulls eye target.
