In order to maintain the appearance of the lock and extend the service life of the lock, care should be taken to maintain and maintain it during daily use.
First, the lock appearance maintenance
1. During the renovation of the house, do not touch the rubberized surface of the adhesive tape with the surface of the lock to seal the exposed parts of the lock handle, panel, etc., so as to prevent the surface treatment layer of the lock component from being decorated with acidic or alkaline materials. And the erosion of gas produces spots, blistering and even delamination, which seriously affects the appearance quality of the lock.
2. In normal use, if there is dirt, use a dry cloth to remove it. Do not scrub with chemicals such as detergent. Otherwise, the exposed protective film will be destroyed, causing discoloration. Do not wipe the lock body and handle with a damp cloth, as some metal locks will rust; alloy locks will wear away the coating and lose the aesthetic effect.
Second, the lock performance maintenance
1. During the use, regularly (half-year or once a year) or when the key is not inserted smoothly, add some graphite powder (pencil powder) to the keyhole to lubricate. Do not add any liquid oil as a lubricant to prevent the grease from sticking to the marble spring, causing the lock to not rotate and not open. If the door is closed, if it is more laborious, you can solve it by applying a little pencil powder on the oblique tongue.
2, when closing the door, it is best to hold the handle, screw the lock tongue into the lock body, then close the door and then let go, do not force the door, otherwise it will reduce the service life of the lock. Because the sealing strip installed between the door body and the door frame has a spring force, when the door or the key is unlocked tightly, the door can be pushed or pulled by the door while the door is opened to overcome the elasticity. Do not turn the handle or the key to open the door. So as not to break the handle or the key.
