In order to maintain the appearance of the lock and prolong the service life of the lock, attention should be paid to its maintenance and maintenance during daily use.
1. Always keep lubricant in the transmission part of the lock body to keep its transmission smooth and prolong its service life. It is recommended to check once every six months or a year, and at the same time check whether the fastening screws are loose to ensure fastening.
2. During the use of the lock head, periodically (half a year or a year) or when the key is not inserted smoothly, you can put a little graphite powder or pencil powder in the lock cylinder groove to ensure the smooth insertion and extraction of the key. But do not add any other oil for lubrication, so as to prevent the grease from sticking to the pin spring, causing the lock head to fail to rotate and cannot be opened.
3. Always check the matching gap between the lock body and the strike plate, whether the height of the bolt and the strike plate hole is appropriate, and the best fit gap between the door and the door frame is 1.5mm-2.5mm. If any changes are found, adjust the position of the hinge or strike plate on the door. At the same time, pay attention to the cold shrinkage and heat expansion caused by the weather (wet in spring and dry in winter) to ensure that the gap between the door and the door frame, the lock body and the strike plate is reasonable, so as to ensure the smooth use of the lock. For details, you can directly ask the manufacturer when you buy it.
