Standard Setup Procedures
4.
Set the line. Locate Point D. Using the transit, place a new stake
approximately 5 m (15 ft) in front of the Piper. Look through the
transit and move the beam using the LEFT and RIGHT buttons on the
remote control until the beam hits the stake and intersects with the
transit's cross-hairs.
☞
Place the Piper on top of the pipe when the beam cannot pass
through the pipe, for example, when it is filled with water.
1.
Set the grade. Enter the required grade for
the pipe to be laid in the display of the Piper.
2.
Set the elevation. If the Piper is going to be
placed inside the pipe, attach the required
size feet to the Piper. The Piper comes stand-
ard with 150 mm (6 inches) feet, and offers
optional feet for 200, 225, 250 and 300 mm
(8, 9, 10, and 12 inches) pipes.
3.
Set the line. Place the Piper in or on the pipe and adjust the beam so
that it is in line with the next manhole.
☞
This procedure is the best for shorter runs of pipe, typically those
less that 90 m (300 ft).
