Maintenance of safety locks

Nov 01, 2020

Maintenance of safety locks:

1. The locks should not be exposed to rain for a long time. The falling rainwater contains nitric acid and nitrate, which will corrode the locks.

2. Always keep the lock head clean, and don't let foreign matter enter the lock cylinder, which may cause difficulty or even failure to open.

3. Regularly inject lubricating oil, graphite powder or pencil powder into the lock core to help reduce the oxide layer left by the long time of use.

4. Pay attention to the thermal expansion and contraction caused by the weather (humid in spring, dry in winter) to ensure a reasonable fit between the lock body and the key to ensure smooth use of the lock.
