Using the Bosch BP350 is a breeze. First, extend the telescoping pole to your desired height between 4.6 and 11.5 feet. You can rotate the pole sections to set the position easily. Then, use the quick - set clamp to fix the system at the height you need, whether it's close to the floor or near the ceiling. Attach your line or point layout laser to the swiveling threaded mount (1/4 - 20). If you have the optional Bosch WM1 universal mount, you can use its microfine height adjustment system for more precise positioning. When using it, make sure the anti - slip surface on the foot and the ball - jointed head plate are firmly placed on the floor and ceiling to prevent any slipping. For maintenance, keep the system clean and dry. Check the threaded mount regularly to ensure it's in good condition. If you're not using the system for a long time, store it in a cool and dry place.
