Anonymous users2024-01-24Door lock lubrication requires a special low-viscosity synthetic lubricant.
Most of the well-known lock factories such as Escola use fully synthetic lock lubricants from Hotolube or Kluber. Fully synthetic base oil production, clear and transparent, colorless and odorless, low temperature resistance, no dust. Tao is full of 30 ml needle-nosed small oil bottles, drop a few drops, easy to use.
The maintenance interval is six months.
Mineral oil should not be used because it is highly viscous and tends to get dirty. It is also not suitable to use pencil end or black graphite lubrication, which cannot lubricate the internal parts, and there will be heavy metal and color pollution.

You can go to the place where you bought the security door, buy the lock cylinder there, and then ask the boss to arrange a professional decorator. Maybe the boss will give you a certain discount because you are a repeat customer.
