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 × 11 threaded adapter in the
horizontal arm.
6 Transit Alignment – You may
position your transit over the
laser’s bull’s-eye target in one of
the following methods:
a 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 lasers’ bull’s-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 lasers’ bull’s-eye
target.
7 After rough positioning the
transit over the bull’s-eye target,
use the transit's leveling base to
accurately adjust the transit to the
bull’s-eye target.
8 Once the transit is set over the
lasers’ bull’s-eye target, sight the
transit on the centerline of the next
manhole and lock the scope on
line.
