Lock Performance Maintenance

1. During use, regularly (once every six months or once a year) or insert and pull out the keyhole no more than once, add some graphite powder (pencil powder) into the keyhole for lubrication, and do not add any oily substances. As lubricant, coconut oil sticks to the pin spring, causing the lock to be unable to rotate and open. If it is difficult to close the door leaf, you can apply a little powder on the latch tongue to solve the problem.

2. When closing the door, it is best to hold the handle, screw the lock tongue into the lock body, and then let go after closing the door. Do not hit the door hard, otherwise the service life of the lock will be reduced.

3. When the main deadbolt or safety deadbolt is extended outside the door, the force will be strong, otherwise the deadbolt and door frame will be damaged.

4. Since the sealing strip installed between the door body and the door frame has elasticity, when using a blade or the door to open the lock tightly, you can push or pull the door with your hands while opening the door to overcome the elasticity. Do not turn the side or the door with force. Cracks in doors, panels or parts.
