Warranty maintenance

The proper maintenance of the piano not only affects the playing effect, but also relates to the service life of the piano. Maintenance of piano should pay attention to the following aspects:

Carry:Piano weighs more than 200 kilograms, and casters can be used for indoor handling. Long-distance handling requires experienced people to be careful and handled lightly. When the place is narrow, old felt can be used to wrap it in order to prevent collision.

Place:Placed room should be able to fully spread and evenly distribute the sound. Furniture and bookcase can be used to adjust the reverse. Attention should be paid to the use of sound-absorbing materials to control the remaining sound time in about 0.3-0.6 seconds, so as to achieve the beautiful effect of the sound. The vertical piano should be placed about half a meter horizontally from the wall. The piano should be placed away from the heat source to prevent direct sunshine, especially in the coastal areas of China, the residential buildings should also prevent the direct wind, because the wind contains more sodium, magnesium, zinc ions, easy to rust with the metal parts inside the piano.
Moisture-proof:The piano is sensitive to temperature. The optimum temperature is 20-25 C and the relative humidity is about 40-70%. When the relative humidity is more than 75%, the damper and absorbent can be installed in the piano. Zhejiang, Fujian, Shenzhen and Zhuhai are located in the subtropical marine climate environment. Moisture-proof is an important aspect of piano maintenance.

Pest control: Piano cavity is wide, there are wool, felt and other easy to provoke and breed pests. Small cloth bags can be hung on the big bolts on both sides of the stringer and camphor balls can be filled to prevent cicadas. It is worth mentioning that the piano in the teaching unit is often neglected for a long time during the holidays. If it is not properly maintained, it will inevitably become a "pest and rat park".
Cleanliness:Piano surface and keys can be smeared with soft cloth, appropriate alcohol, furniture wax, car wax, etc. No acetone, methanol, etc.

Timely maintenance:Piano breakdowns should be repaired in time. Piano playing with illness can easily damage internal components. At least one comprehensive overhaul should be carried out every three or two months. It would be better if the tuning was checked every three or two months. Because the tension of the strings will change with the change of season, which directly affects the pitch. Regular overhaul and tuning can find problems in time and troubleshoot them so that the piano is always in the best working state. In addition, do not put on the piano camera racks, vases and other decorations, to the rabbit playing when the impact of sound or fall on the surface of the piano body. Attention must be paid to the professional technicians of the original distributor when overhauling, to ensure that the fittings are in line, the maintenance is reasonable and the quality of the piano is guaranteed.
Tune up:Because each string has a huge pull, after a period of time, the piano will go out of tune and need to be tuned to maintain the correct tone. Xinqin can be adjusted once or twice a year. Professionals are required for tuning and maintenance.

In short, as long as the piano is carefully maintained and prevented, a piano will have a long life. It can accompany a person for life and even serve generations.
