5 Applications and Setups
50 DG711 and DG511 Pipe Laser User Guide
9 Plunge the scope into the trench
and set a stake on line 6–8 m (20–
25 ft) from the first manhole.
10 Use the line buttons to intersect
the stake with the laser beam.
11 Look through the transit at the
stake and readjust the beam until it
is aligned with the vertical
crosshair of the transit.
12 Lay pipe – Set the pipe target in
each new section of pipe and adjust
the pipe until it intersects the
target’s bull’s-eye.
Note – This method assumes that
the manhole was set at the correct
elevation. If there is any question
as to the manhole accuracy, check
the manhole and pipe invert
elevation and transfer an offset to
check the line of pipe entering or
exiting the manhole.
On Top of the Pipe
1 Line – Set the laser until it is
over the vertical centerline of the
pipe and pointing toward the next
manhole.
Note – It may be necessary to
support the Laser with extra
gravel, dirt, or sub-base material.
2 Set an adjustable pipe target
(Model 936 or 956) so that the
target’s bull’s-eye is at the same
distance above the pipe as your
laser beam.
