Line (transit method)
1Set a manhole mount and
transit on the manhole.
2Clamp the manhole mount base
to the side of the manhole to
establish a stable transit support.
3Secure the vertical arm into the
manhole mount base.
4Assemble the horizontal arm,
horizontal clamp, and vertical
support clamp to the vertical arm
and position over the top of the
laser.
5Attach your transit to the
5/8×11 threaded adapter in the
horizontal arm.
6Transit Alignment – You may
position your transit over the
laser’s bull’s-eye target in one of
the following methods:
aUse 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.
bPlumb 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.
7After 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.
8Once 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.
