HOW TO SET GRADE WITH A LASER LEVEL
Set up your laser level on a tripod on firm, dry ground while making sure it’s stable. Turn on the laser level, and give it a moment to self-level. Identify the initial height of your grade, because the pitch will slope downward from there. Place the bottom of the leveling rod at the desired height, adjust the laser detector up or down until you hear a beep, and secure the detector. Identify the desired amount of fall from the top of the grade to the bottom, move the detector up to the desired height, and secure it. Walk to where the bottom of the grade will be, and find level with the laser detector. Depending on the workspace, you will have to either lift the rod or dig into the ground. The bottom of the leveling rod represents the bottom of the grade. Mark the spot by inserting a stick into the ground, and make sure it displays your desired height.
HOW TO OPERATE A ROTARY LASER
These types of laser tools can help you work faster, safer, and smarter. They’re ideal for grading, concrete flatwork, masonry work, as well as for setting forms and fittings. A dual-slope model will allow you to tilt the laser into one or two planes, which can eliminate the need for complex slope calculations while you’re on the job. Once you turn the device on, it will self-level and rotate along a horizontal plane. If tilt mode is on, the laser will shut off if it’s bumped. This will prevent erroneous measurements due to laser movement. If tilt mode is turned off, the device will automatically re-level and restart if it’s bumped. A rotary laser level can make it easier to set up drainage ditches on concrete flatwork as well as on any type of grading project.
