If the surface of the safe is stained, do not use chemical solvents to clean it. Use a clean cloth dampened with a small amount of detergent. Lubricate the protruding bolts and drawer wheels with a small amount of lubricant (household cooking oil is also acceptable). Inject a small amount of pencil lead powder (graphite) into the key cylinder to make key insertion, removal, and turning easier. A safe is an anti-theft device; if used responsibly and with attention, its security level will be greatly improved.
① When turning a mechanical combination lock, turn it slowly and gently, never force it. Remember the direction and number of turns. If you accidentally exceed the marked line, do not reverse; you must start over. ② It is best to set the combination with the safe door open. After setting the combination, enter the new combination several times to confirm it is correct before locking the door. ③ Never lock the instruction manual or emergency key inside the safe. ④ When using the alarm, do not arbitrarily adjust the internal switches and electronic components. If the sound becomes quieter, the battery is dead; replace it in an emergency. If a false alarm occurs, the sensitivity can be appropriately lowered. ⑤ To ensure the safe is securely fixed, the taper pin in the expansion nut must be hammered until the nut expands and tightens. The nut must be fully secured in the wall hole. ⑥ The safe must be firmly secured to the concrete wall. ⑦ If an external battery is to be used for an extended period, the battery should be removed from the battery compartment.
