Pipe Laying Overview
The three basic steps to successfully set up the GradeLight for laying pipe are:
A. Dialing in the correct grade.
B. Transferring the elevation to position the laser at the correct height.
C. Aligning the laser beam to the forward manhole.
Before Starting
Attach the necessary mounting accessories, such as the handle/rod mount, trivet, legs, etc. to
the unit. Power-up the unit and adjust the line control to the center of its range.
At the beginning of a pipe laying job, consider the following tips for improved performance:
• The GradeLight can be used to check the hubs prior to actually starting the work. This is an
opportunity to catch potential errors before using the hubs as a reference to lay pipe.
• Place grade rod or marker at the forward manhole for a place to align to.
• When the last joint of pipe has been laid approaching a manhole, bring the GradeLight
forward so that as soon as the manhole is in place, you can set up again without delay.
Laser Start-up
Press On/Off button to power-up the laser.
Check the following indications on the LCD:
The start-up screen shows AGL.
The battery capacity is displayed. Charge when there is one bar left.
The laser automatically self-levels, and returns to the same grade and
line settings as last used. If the LCD laser beam symbol is flashing, it’s
still leveling. When the symbol is lit solid, the laser has leveled and is
ready for use.
Likewise, the beam emitted from the unit flashes until it has leveled.
Check the electronic cross axis vial. If it’s out-of-level, rotate the laser
slightly to the left or right to level the cross axis.
The bubble should be between the lines on the vial.
Before each setup, center the beam using the laser keypad (press both
arrows simultaneously for 2 seconds) or the remote (press CL button).
