Q: Where is the calibration screw located on the BOSCH QUIGO laser level?

On the BOSCH QUIGO laser level, the calibration screw is located at the back of the device . This screw allows for precise adjustment of the horizontal and vertical laser lines to ensure measurement and leveling accuracy during your work. Location and access: Turn the QUIGO laser over to access its back panel. Locate a small removable protective cap or cover that covers the calibration screw. Gently remove this cap by pulling it towards you. The calibration screw is now exposed and accessible. Using the screw: Use an appropriately sized screwdriver (usually a small Phillips screwdriver). Turn the screw very slightly to adjust the laser alignment. Check after each small adjustment by positioning the laser against a known reference line (vertical wall or horizontal floor). Do not force the screw to avoid damaging it or breaking the internal mechanism. After your calibration adjustments, replace the protective cap to protect the screw and keep the device in good condition.
