Using the Bosch GOL 32 CK is straightforward. First, set up the aluminum tripod on a stable surface. Then, use the plumb bob to center the level on the tripod. Attach the level to the tripod using the 5/8 - 11 thread. Look through the 32x - power telescope to view your target. The crosshairs and stadia lines will help you measure height and distance. When not in use, always store the level in the hard case to protect it. Keep the lens clean with a soft cloth. Avoid exposing the level to extreme temperatures and humidity. Check the compensator and vial bubble regularly to ensure accurate readings. If you have any issues, refer to the limited 1 - year warranty for support.
