1. After the product installation is completed, if the site is still undergoing construction and decoration, please pay attention to protecting the door frame and leaf from collision with heavy objects or sharp objects. (Remind on-site construction personnel to pay attention or paste thick cardboard on both sides of the door leaf for protection)

2. If stains or dirt are found on the surface of the door after removing the protective film or during future use, a clean and dry soft towel can be used to wipe it clean. Do not use detergent indiscriminately

Before the decoration is completed, please keep the owner's key safe. After the decoration is completed, the decoration keys should be retrieved and the owner's key package should be opened in a timely manner. Use the C key to dispose of the decoration keys (refer to the AB key usage instructions in the key package or consult our company's customer service hotline by phone for specific usage methods). If the decoration keys are broken, they should be scattered and discarded separately.

4. In daily use, keep and maintain the cleanliness and dryness of the door body, and try to avoid the product from being exposed to rain and sunlight as much as possible

5. Both light and dark hinges have a certain opening angle limit. When the door is opened to its maximum angle, do not push it hard again, otherwise it will damage the door accessories and even cause serious problems such as the door leaf not being able to open and close

6. The closing action should be slow and gentle, and the door leaf should not be pushed forcefully, otherwise it will cause damage to the lock, the flatness of the door leaf, and the sealing performance of the door body

7. When opening and closing the door, it was found that the locking tongue was not flexible enough. You can apply a little butter or clean lubricating oil evenly to the side of the movable inclined tongue that collides with the door frame, and open and close it back and forth a few times to solve the problem. Regular maintenance like this can keep opening and closing easy and smooth at all times

8. When it is found that the door hinge is difficult to open or makes abnormal noise during use, a little butter can be used to lubricate the axis position of the hinge rotation to solve the problem

9. It is strictly prohibited to pour any oily liquid into the lock cylinder! When you find that the key entering and leaving the lock cylinder is not flexible and has a sense of obstruction, you can use pencil ash to scrape the key and repeatedly rotate the lock cylinder a few times

10. The main lock hole and auxiliary lock hole of the door frame may have a few sharp edges after mold processing. Please urge children not to insert their fingers to avoid cutting; At the same time, children should be educated not to use anything to fill the relevant holes, otherwise it will cause the door leaf to fail to open and close normally

11. Due to the tight fit between the craftsmanship and gaps of this product, please educate children not to place their fingers on the opening and closing positions of the lock and hinge edges when opening or closing doors to avoid injury. It is absolutely forbidden for children to play games related to the door, such as hanging the door leaf or frequently opening and closing the door leaf

12. If any other abnormalities or uncertainties are found during use, please do not solve them on your own. Please call our company's agent or service hotline in a timely manner to consult and provide feedback on the corresponding issues, so as to obtain relevant support and services in a timely manner and solve the related problems as soon as possible

13. Close the door well in windy weather to prevent the strong wind from blowing the door leaf and damaging the lock; It is normal for the virtual position of the product to be tight at the beginning of use (no shaking of the lock tongue and lock hole), and it will naturally become smooth after a period of use. Do not adjust the virtual position easily

14. Please read this manual carefully before use and pay attention to relevant reminders. After the product is installed, please cooperate with our customer service personnel to provide feedback. Please keep this warranty card and manual properly (stored together with various home appliance warranty cards) for future use
