During the use of keyed alike padlock manufacturers, pay attention to their maintenance. 1. Always keep the transmission part of the lock body with lubricant to keep its transmission smooth and prolong its service life. It is recommended to check once half a year or once a year, and at the same time check whether the fastening screws are loose to ensure the fastening.
2. When the lock is in use, regularly (half a year or a year) or when the key is not smoothly inserted, a small amount of graphite powder or pencil powder can be put into the lock core slot to ensure smooth key insertion. However, do not add any other oils for lubrication to avoid the grease sticking to the pin spring, causing the lock head to not turn and not open.
3. Frequently check the fit gap between the lock body and the lock plate, whether the height of the lock tongue and the hole of the lock plate is suitable, and the best fit between the door and the door frame is 1.5mm-2.5mm. If you find any changes, you should adjust the position of the hinge or the lock plate on the door. At the same time, pay attention to the cold shrinkage and thermal expansion caused by the weather (wet spring, dry winter) to ensure that the gap between the door and the door frame, the lock body and the lock plate is reasonable, to ensure the smooth use of the stainless steel lock.
