2. During the use of the lock, periodically (half year or year) or when the key is not inserted smoothly, a small amount of graphite powder or pencil powder can be put into the lock cylinder to ensure the key is inserted and removed smoothly. However, do not add any other oil to lubricate to prevent the grease from sticking to the marble spring, causing the lock to not rotate and not open.
3. Always check the matching clearance between the lock body and the lock plate. The fit between the lock tongue and the lock plate hole is appropriate. The fit between the door and the door frame is preferably 1.5mm-2.5mm. If changes are found, adjust the position of the hinge or lock plate on the door. At the same time, pay attention to the thermal expansion and contraction caused by seasonal changes, to ensure that the clearance between the door and the door frame, the lock body and the lock plate is reasonable, so as to ensure the smooth use of the lock.
