To maintain the appearance of the lock and extend its service life, attention should be paid to its maintenance and upkeep during daily use.
1. Regularly keep the transmission part of the lock body lubricated to ensure smooth transmission and extend its service life. It is recommended to inspect every six months or a year, and also check if the fastening screws are loose to ensure tightness.
2. During the use of the lock, a small amount of graphite powder or pencil powder can be applied to the lock cylinder slot regularly (six months or a year) or when the key insertion and extraction are not smooth to ensure smooth key insertion and extraction. But do not add any other oil for lubrication to avoid grease sticking to the spring, causing the lock head to not rotate and not open.
3. Regularly check the fit gap between the lock body and the lock buckle plate, whether the height fit between the lock tongue and the lock buckle plate hole is appropriate, and the optimal fit gap between the door and the door frame is 1.5mm-2.5mm. If any changes are found, the position of the hinge or locking plate on the door should be adjusted. At the same time, pay attention to the cold shrinkage and heat expansion caused by the weather (humid in spring and dry in winter) to ensure that the gap between the door and the door frame, lock body and lock buckle plate matches reasonably, and to ensure smooth use of the lock., You can directly ask the manufacturer's personnel for specific information when purchasing.
