OPERATING A ROTARY LASER
Dual-slope rotary lasers can help you work faster, safer, and smarter. It’s perfect for grading, concrete flatwork, masonry work, as well as for setting forms and footings. With a dual-slope rotary laser, you can work on one or two planes (which allows you to make more complex slope calculations on the job). Once you turn the unit on, it will level itself on a horizontal plane. And if “tilt mode” is enabled, the laser will turn off if it’s bumped. This eliminates the chance of erroneous measurements. If this feature isn’t enabled, it will automatically restart and re-level if it’s bumped
HOW TO USE A LASER LEVEL
Set up the laser on a tripod or flat surface. If it’s a manual level, make sure the bubble vials show level. If it’s a self-leveling model, it will take a moment to level itself once the unit has been turned on. The device will emit a laser beam that will show level on a wall or across an outdoor workspace. And depending on the type of laser, it can be dot, multiple-line, or rotary (which shows level at 360 degrees horizontally and vertically). You can use a laser detector to intercept the laser if there’s no wall to “catch” the beam (which is typically required outdoors). Connect it to a measuring rod, adjust it up or down until you hear a beep, secure the detector in place, and make measurements as necessary.
