1.To increase the service cycle and smooth out the transmission, lubricate the lock body transmission and keep it in place. It is advised to perform an examination once every six months or once a year, and during the inspection, the screws need to be tightened.

2. To ensure that the key inserts and extracts smoothly, periodically smear a tiny bit of graphite or pencil powder into the lock cylinder hole when the lock is in a safe operating condition. To prevent grease from adhering to the spring sheet and preventing the lock head from rotating, which would prevent the lock from opening, additional oils cannot be applied as lubrication.

3. Occasionally, measure the mutual matching distance between the locking plate and the lock body, determine whether the locking plate hole and the lock tongue height are appropriate, and note that the ideal mutual matching distance between the door and the door frame is between 1.5 and 2.5 mm. Make precise adjustments to the door's catch plates or hinges if you observe any changes. In order to ensure that the space between the door and the door frame and the lock body and plate is appropriate and that the locks can be operated securely and smoothly, it is also vital to take into consideration the cold shrinkage and thermal expansion brought on by weather conditions.
