Rotary Laser Level Alignment Cen Tech Harbor Freight 92801
How to align a manual laser level. Do not mess with the two vial adjust screws until you understand the method. The vials on an instrument like this limit the accuracy to about 1/4 inch in say 30ft. Other brands state 1/4 inch in 100 ft but my tests point more towards 1/4 in say 50 ft.
