How to Set Up Laser Levels to Establish Grades

Laser levels, sometimes called laser transits or optical builder's levels, can help you establish grade levels for landscaping and building projects. You should place the tripod where it can remain undisturbed for the entire project, if possible, so you always use the same base point for measuring grade. Double check accuracy occasionally if you're using big machinery, since the vibrations may knock the laser level out of alignment. If you rent a laser level from a tool rental store, check the kit to ensure that all parts are there and in good condition before taking it home.

Instructions

1. • 1

     Set up the laser level on firm dry ground so it doesn't shift as you walk around. Push the tripod's pins into the ground as far as they will go.

   • 2

     Mount the level to the tripod securely. Use the adjustment screws to bring the level's bubbles into the center. Don't worry about exact accuracy at this point.

   • 3

     Swing the level around 180 degrees and center the bubbles again.

   • 4

     Return the level to the starting position and check the bubbles. Adjust as needed until the level is accurate in all dimensions.
