SurfaceSticky stains formed during useYou can try wiping with alcohol or a tar remover.
Dents from corner or face impactsFor minor dents, fill with wood filler; for severe dents during use, contact a local door-repair technician.
Accidental scratches and abrasions

  1. For worn paint, apply grease to the worn area to fade the worn surface, or spray on a self-drying paint of matching gloss.

2. Lightly apply a marker pen of a similar color.

3. If paint loss is severe, find a local paint technician or ask a local furniture factory to help with paint repair.

Stains on the bottom door-frame rail


Wipe with rust remover and lacquer thinner.



FittingsSlight hinge creaking during use1. Replace the creaking hinge.
2. Add grease or a little lubricating oil to the hinge central pin.
The external lock cylinder won’t open1. Check whether there is a foreign object inside the cylinder; if so, remove it, then add pencil (graphite) powder and open it with the key.
2. It is recommended to destroy the cylinder and replace it with a new lock.
Stiff key turningLoosen the screws on the handle by half a turn or one full turn.
InstallationDoor gap rubbing against the frame1. Carefully observe the rubbing marks between the frame and the leaf. These marks are what makes the door tight; once found, place a shim above the mark and tap it with a hammer—be sure to control the force. If the door can still close, it means it is not very tight, so this method will surely work. If you cannot control the force well, start gently, try opening and closing the door, then add a bit more force. After several adjustments it will be fine.
2. Simply adjust the screws on the hinge.
Door frame not flush against the wallFirst lay packing paper on the floor, then place the door flat on it; put a towel under the uneven spot and step on it gently a few times.
Protective film left on too long and won’t peel offIf the film won’t peel off, soak it with a hot wet towel to soften it, then peel it off bit by bit. Remove the protective film promptly after the door is delivered.
OpeningFingerprint/code lock out of power with no keyYou can use a power bank for emergency charging to open the door.
